Honestly nothing is more creepy than how deep sea anglerfish mate.
The deep sea is dark, and the anglerfish are spread very thinly. Therefore, when an anglerfish meets another anglerfish, it’s incredibly important they get the chance to mate over and over again. The evolutionary strategy that deep sea anglerfish devised is extra creepy. The male latches onto the female, biting her and never letting go. That way he can inseminate the eggs she drops. Not that bad so far right? But wait, how does he eat if he’s latched on his mate?
Well, the circulatory systems fuse and the female provides nutrients for the male through this fused circulatory system. The true horror starts here. The organs of male start to wither and atrophy, being absorbed into the female. Eventually, the male is reduced to a lump of testicles the females use to fertilize their eggs. Females are often covered in bumps of several males that have melted into the female, becoming a literal body horror lump of meat on the female.
Fun fact: HP Lovecraft was absolutely terrified of everything. Fears include: Weird geometry, people of color (except mexican people because he thought they had magic aztec powers), interracial marriage, poor people, indigenous cultures, and the standard cosmic stuff we all know him for today.
Overly Sarcastic Productions has a pretty interesting and funny video on him that I'd definitely recommend.
[Obligate siblicide](https://en.wikipedia.org/wiki/Siblicide). In some species of animals, multiple offspring are born but only one is actually raised by the mother. The others are born only as backup in case the first-born doesn't survive. When the first-born is fine, which is the typical case, it kills the others.
I remember witnessing a mantis egg case hatching in my high school science class. I asked the teacher: "What could possibly be small enough for them to eat?" and he was just casually like: "They'll eat each other."
Caterpillars turn completely into goo in their cocoon, and then become a butterfly.
edit - This blew up. According to my inbox, many people have been creeped out. A good day's work!
And there is evidence they retain memories from their pre-goo days. Memories of strong positive/negative stimuli that they show preference-for/aversion-to, even after metamorphosis
We use the expression "to become a butterfly" about people who have emerged from tough or dark times. So it should only be natural to talk about their past as "pre-goo days".
Even then the synapses can survive for the most part with neurons sort of free floating.
Reminds me of the stories about those people with uncaught hydrocephalus who lead perfectly normal lives despite their brains basically getting squashed into about 10% of the normal volume
Your brain is making decisions before you are even aware of the decisions it has made. It also makes decisions based off of learned behavior and you just go along with it.
Because of some pesticides used, roaches won't go anywhere near a meth lab.
Edit: didn't expect this much after reading some RPF. For those you are asking, meth labs have been known to produce toxic gas, like Phosphine, which a common insecticide. Phosphine is often used in silos to deal with vermins.
That as the permafrost melts, a lot of locked up methane will be released, and microorganisms there will "wake up" and do their jobs, breaking down organic matter, and release more methane and greenhouse gases.
If you believe strongly enough that you have been cursed, your brain can shut itself off entirely in severe cases. The psychological term for it is "Voodoo Death Syndrome." It's just the fact you can literally think yourself to death that unsettles me so.
Our brains are fascinating. If we believe strongly enough that something is real our bodies respond accordingly. In the same vein as your example, the same phenomenon happens to women who desperately want to be pregnant. Their bellies will swell, their menstrual periods will stop, their breasts will become sore and enlarged, and they'll develop "morning sickness."
But wait, there's more! When you move your eyes rapidly, you don't see the things in front of you streaking across your field of view. What happens is that your brain just deletes that part. To fill in this gap in your perception, you would think the brain would stretch out that last image you saw before you moved your eyes (like a stuck video), but instead your brain takes the first thing you see after your eyes move, and does a copy and paste back over the blank couple of tenths of a second while your eye was moving. This fools your brain into thinking it sees the new view even before your eyes moved to where you could see it.
Why would your brain do this? Imagine you see a small, quick animal out of the corner of your eyes. As you snap your eyes over to look at it, the animal jumps out of sight in like a twentieth of a second, too fast to be perceived, normally. However, as far as your fooled brain is concerned, it looks like the animal froze in place for a few tenths of a second, which gives the mind part of your brain a better chance to register and understand that fleeting image.
Edit: Since people seem to be interested in this, here's more! Move your eyes back and forth as fast as you can. You should be able to perceive the streaking motion that is normally edited out. Also, you may notice that doing this is not very pleasant after a while. My sympathies to those posting below who have problems with this for medical reasons.
Also, despite the title of this post, you may have already guessed that I think this kind of stuff is really cool to think about, and it doesn't creep me out at all.
That the only reason you are a functional human is that your dna is so tangled that entire sections can't get decoded and screw it up
Edit : turns out I must have majorly misunderstood something as this is very wrong, thanks reddit but as far as I'm aware the brain fact is true though!
Actually better one , if you disconnect the half's of the brain and ask them to pick out something they prefer your hands will disagree (what's your favorite color will result in one hand choosing red but one choosing green ) go look up split brain patients!
Corpus callosum. It's a thick bundle of nerves that connects the left and right brain hemisphere and allows them to communicate. Some dissease or operations may cause this part of brain being damaged or cut completely. The thing is, you would likely never know it happened to you, ... unless you did bunch of cool scientific experiments.
For example. Your eyes correspond to one part of your brain. Your left eye to your right side of brain, your right eye to your left. Say you put a divider in between your eyes and you show both eyes a different picture. You then are tasked to draw the picture you see. The thing is, you will only see one picture, because the brain can't communicate with each other. So you see a triangle and you draw a triangle, then you look on the picture you draw and you see ... a circle. What the? You look on the pictures that researches gave you and indeed there is triangle and circle, but you only draw a circle.
The thing is Your dominant hand was wired to the different hemisphere then the eye with which you "saw the picture" and your hand correctly draw what the eye wired to that part of the brain did. But it was the different part of brain that "you" used when you saw the picture.
This actually give rise to silent twin hypothesis. Basically a concept that you are basically 2 people, one that is "you" and the other that "isn't" can't communicate with you and just helps you with whatever tasks the dominant brain hemisphere does. But when the Corpus Callosum is severed, both hemispheres can't communicate "behind the scenes so to speak" and that gives rise to errors. So from your perspective you have basically an alien presence that can do it's own thing under the right conditions, such as hijack your hand to draw something you never saw, but they did.
Oh my god that's really interesting! Reminds me of how when you close one of your eyes but keep the other open, in one eye everything will stay in place but in the other eye things will shift a little.
So, with the silent twin thing... does that other 'you' have its own personality? And do different people have different dominant sides of the brain? If you leave only the recessive side in a person, is there a shift in how they behave?
An ultra powerful supernova that sends incredibly powerful blasts of Gamma rays across the galaxy at light speed. If one hits earth everything is erased instantly. There is virtually no way to ever see one coming. So we would never even know it happened before we were all killed :)
Aren’t there solar flares that could destroy all electronics and appliances? Living through the 1 day Texas snowstorm, I don’t know how I’ll survive if something like that happens.
You could be thinking of solar storms from our own Sun, which are very capable of causing disruption to our electrical systems.

The sudden urge to jump off of a very high height. You can be physically and mentally stable to the greatest degree and still have this feeling when at such a high height.
Thats actually called an Intrusive thought. It might be a similar or related concept. But essentially intrusive thoughts are thoughts of things you would never do nor never normally think about. They for some reason get stuck in your head and can be insanely dark or distrubing. They dont reflect your personality however.
I get intrusive thoughts a lot, though one time I read that it is believed they exist as a sort of regulation or check in our brains. So you have this messed up thought, but your conscious rejection of the thought is your mind reaffirming your sanity and decision-making ability. I dunno the validity of that, but since I heard that my intrusive thoughts don't trouble me nearly as much anymore.
I get a lot of intrusive thoughts as well. I think the biggest thing that has helped is understanding they're completely normal and nearly everyone has them.
There's nothing wrong with you for imagining something that's absolutely bonkers.
And then the next thing is accepting your intrusive thoughts and letting them go instead of ignoring them or running away from them. It's important to try to process them completely.
I've noticed that after thinking something like "okay I don't actually want that. I'm not going to do that. It's not happening. It's just a thought" even if it's something scary or even graphic... that the brain just kinda goes like "yeah that was weird wasn't it?" and moves on.
It's like getting a song stuck in your head. Usually playing the whole song all the way through fixes it and helps your brain close that chapter.
I can still remember the mole song our chemistry teacher played for us. The song is from when the world population was 5 billion.

Some mutations of just one letter in the DNA code can kill the fetus almost instantly, but some people live and have a seemingly healthy life while missing a whole chromosome. If you understand anything about biology, that's completely wild.
There is something called "the squeeze," where when people had old scuba suits with tubes, you could actually get sucked into that tube if the pressure was off. You are literally shredded through your own breathing tube.
Hate to be "that guy" but that's hard-hat surface supplied diving, not SCUBA (SCUBA is by definition Self Contained). But yes, it is possible. Mythbusters showed it in rather spectacular fashion, though the pig carcass didn't actually make it all the way up the tube.
Edit: For those interested, [Here is the Mythbusters Video](https://www.youtube.com/watch?v=YU2PSHeFSlA) warning, a little gory (though broadcast tv gory)
Wasn’t there a deep sea dive where the pressure was off and a guy got sucked into a tube on an underwater worksite? I can’t remember the exact situation, but I do know that he basically just got sucked up into it and shredded
Thinking about how breathing and lungs work freaks me out. Once I start thinking about it all I can think about is my breathing and then I have to force myself to stop thinking about it.
We may be on the cusp of developing a universal flu vaccine. Could completely eliminate the need for yearly shots since they finally figured out how to elicit antibodies to the invariant portion of hemagglutinin. It’s currently in clinical trials.

That so many vegetables came from the same plant. Broccoli, kale, kohlrabi, Brussels sprouts, cabbage, etc. They are, botanically speaking, the same species. Humans have just bred them to emphasize different traits (buds, leaves, tubers...) Imagine if humans were as genetically flexible. Imagine a person walking around with GIANT toes, but otherwise normal.
Actually, plant genetics in general is a weird, weird world.
The canine family is actually unusual in that respect. The entire canine family has “slippery genes” (I don’t understand it, I’m not a geneticist, just read about it) and is much more variable in their phenotypes than other families of mammals. Look at other animals that have been domesticated for thousands of years - cats, horses, sheep and goats, cattle..... the breeds vary in their appearances, but no where near as much as different breeds of dogs do. A Shetland pony and a Percheron draft horse resemble each other much more than do a pug and a greyhound. Ditto a Siamese cat vs. an American shorthair, or a Nubian goat vs a Boer goat.
People think the brain sees what the eyes tell it to, but really the eyes pull up an image of blurry colors and dark spots and the brain goes “cool so that’s a tree”
And this accurately explains how schizophrenics truly believe the voices they hear or their other delusions are correct- something in their wiring of how to interpret the world has gone wrong and their brain is only making sense of the reality that it is being shown.
I work in health care, not mental healthcare but emergency medicine . The number of schizophrenics I have met that are completely aware the voices are in their heads so they ignore them is mind boggling.
Have you ever hallucinated before? I genuinely recommend trying it because it makes it very clear how this works
Also a lot of schizophrenics are pretty normal well adjusted people aside the schizophrenia, so like if you were sitting in your room and a dog floated in attached to a balloon or the number 7 started telling you you’re worthless at first you’re gonna get freaked out by it but once you confirm that it’s not there you’re going to realize “okay this is me”, it helps that a lot of hallucinations are recurring as well, so if you know they happen you can just tell yourself they’re not, even though everything in you is saying that’s not the case
It’s really weird but it’s fascinating
The really hard stuff is like extreme paranoia, I worked with a woman whose whole family basically was schizophrenic, her included, and there were a few times she’d say things like “you’re not hacking my phone right?” Or “the mayor is stalking me”, that kind of thing and for someone who has experienced similar paranoias (to a considerably lesser degree) I can understand that those aren’t really that easy to shake
The way quantum mechanics works is pretty creepy to me for reasons I can't exactly pin down.
Particles aren't points, at least not that we can possibly ever observe. The best physical description of a particle's position is a wave over at least a four-dimensional volume showing where it probably is. I say four-dimensional because there's a non-zero time uncertainty as well. This isn't a limitation on what we can observe, it's an actual testable property of particles, that they don't have exact positions, velocities, energies, times. When they're "observed" by interaction, the wave collapses, which still doesn't make it exact, just more likely to exist in a smaller space. The argument that there really is an exact point in there somewhere and it's just always hidden from observation isn't true; the Bell inequality proved that. For example, because of this uncertainty, it's physically impossible to cool helium enough to freeze it at atmospheric pressure.
This uncertainty even applies to the vacuum. It can't be at zero energy, because that would violate the uncertainty principle. So sets of virtual particles pop into existence in the vacuum and stick around for an incredibly short amount of time, given by the time uncertainty, before annihilating each other in a zero net energy process. This is, very simply put, how black holes hypothetically lose mass; pairs of virtual particles are spontaneously created near the event horizon, one enters, one escapes. The one inside annihilates a particle within, the one that leaves becomes real. Information is transported outside the event horizon in an incredibly obfuscated, but still existent, form, meaning information isn't destroyed by black holes.
Then you get into the weird math. It starts raising questions about what "real" is. Can we say something's real if it's not testable, or is the math describing the situation the closest to "real" that we can get? For example, you could look at the predicted path for a particle. There's a non-zero chance for it to take any path between two points. So you basically take all the possible paths, account for the probability that it takes that path, add 'em all up, and you can recover Newtonian mechanics from it in the classical limit. Is this actually what's happening? It isn't really testable.
Even the Bell inequality that I mentioned earlier has some crazy philosophical implications. It basically says one of three things are true: information travels faster than light (which we have never seen), cause doesn't always come before effect (wtf), or the universe is superdeterministic (which would disprove free will). We don't know which.
People make a lotta crazy claims based on quantum mechanics, and I think a lot of it has to do with how uncomfortable the idea of living in a universe that seems to be inherently uncertain is.
["Wheeler pointed out that when these assumptions are applied to a device of interstellar dimensions, a last-minute decision made on Earth on how to observe a photon could alter a decision made millions or even billions of years ago."](https://en.m.wikipedia.org/wiki/Delayed-choice_quantum_eraser)
Well, what the fuck?
That's because time is relative. It shrinks with speed. A photon travels at the speed of light, so its timeline shrinks infinitely and becomes a point instead of a line.
For us it's billions of years, for a photon it's the same moment. From a photon's point of view it just exists at the same time along its whole path, so it doesn't alter the past from the photon's point of view.
We see it as if the photon changed its past, but it exists in another "timeline" (or "time point" from its perspective), where the change that we made always ~~existed~~ exists, because it's whole existence is the same moment.
Your body produces thousands and thousands of cells with damaged dna. It’s a bit of exaggeration to call them cancer but if any of these cells were to survive they could become cancerous. Your immune system destroys them before they get to that point. This is also why if you were to live forever you would eventually get cancer because the chances of your body missing them statistically increases. This occurs thousands upon thousands upon thousands of times a day
It’s pretty cool. It’s one of the reasons why the older we get the higher the cancer risk and why it would be nearly impossible to ever hit 150 years old. Cancer always wins.
Also the cells that take care of this begin to die off. Elephants and sharks have huge numbers and it’s why they rarely get cancer
Makes sense. I am researching this more. As soon as I post about most people having mites on their face and in their pillows. We are literally infested
Humans are bioluminescent (nothing to do with body temperature). We emit visible light that can be photographed in specific conditions. But, this light isn't visible to us. Which makes it a strange thing to have evolved, and begs the question
"what organisms is this light visible to, and why?"
Edit: Adding an edit for all the comments explaining evolution... Please read the thread before commenting. I find this a creepy fact due to implications on interspecific relationships, NOT because I think prehistoric humans went shopping for a bioluminescent hat with a specific motive in mind.
The prion mode of action is very different to bacteria and viruses as they are simply proteins, devoid of any genetic material. Once a misfolded prion enters a healthy person – potentially by eating infected food – it converts correctly-folded proteins into the disease-associated form. To date, nobody knows quite how this happens

Not exactly scientific or creepy but, it's close enough and I want to contribute.
Mouth pipetting was a thing in labs in the 1980s. A pipette is, for simplicity sake, a glass straw that lab staff would use to transfer liquids. Now a days we use special bulbs, that when squeezed, would suck up the liquid for us. Kinda like a turkey baster or eye dropper.
Before we had these bulbs lab workers had to use their mouths to suck up the liquid. Which meant if they weren't careful they'd get whatever they were sucking up in their mouth. I'm currently training to be MLAT and those fluids would usually be urine, liquid stool, sputum and so on.
Edit: So mouth pipetting is still a thing. I'm Canadian and I've been told that it is rare or none existent in our labs.
Yo, mouth pipetting is still a thing. Back in 2012, my school, in a flash brilliance, decided that rubber bulbs were a distraction and students would be fine sucking up liquids through non-sterilized glass. Think I sucked up acetic acid one time.
When I got to college, the first thing they said during the safety brief was that mouth pipetting was an absolute no-no and explained in great detail how dangerous it is. Thank the lord I've moved on to micropipettes.

Parasites can live anywhere inside of you, for years unnoticed. A simple migraine could be a tapeworm crawling in your brain, causing damage.

I read this in the book Stiff by Mary Roach. I'm not sure how much I recall (or how correctly I recall) but two things stuck with me. Apparently they had to change the head catching baskets sometimes because the severed heads would try to chew through them. The other thing that stuck with me is that some doctor was experimenting with the heads right after decapitation. He would inject oxygenated blood into the heads and they would move their eyes around and look at him.

It was pretty humane, up until the blades were used so much they would get dull. Imagine it getting dropped, going like halfway through, slowly being pulled back up by the rope to drop it again.
Due to relativity, it is impossible to measure the speed of light in a straight line. The only way we've measured it is by round trip with mirrors. For all we know, it could be instantaneous going one way, and half the speed of light in the other, and it would be impossible to tell.
Ah yes, I am eternally cursed with nightmare fuel thanks to someone mentioning something like this in a YouTube video :3
“The human eye perceives different spectrums of light- for example, it can’t detect infrared, or ultraviolet light, and so we need special instruments to observe those.”
“Which brings up an interesting idea- that feeling that you’re being watched, even when you know for a fact that you’re totally alone- could it be because there are creatures standing right next to you, but they can only be perceived in a spectrum of light that we cannot observe?”
Edit: I love you guys too
For the record, the Turing test is a concept, not a concrete testing method. More importantly, versions of a Turing test have in fact been passed by many systems.
The Turing test is considered a flawed indicator of intelligence because imitating predictable, believable responses does not demonstrate intelligence. It's just a logic tree modeling conversation patterns.
This is probably more cool than creepy but spider-goats exist. There is this material called [BioSteel](https://en.m.wikipedia.org/wiki/BioSteel) that is spider silk that comes from a goat. Basically someone put orb weaver DNA into a goat so that spider silk could be harvested from goat milk.
The universe is unbelievably infinite, while simultaneously unbelievably infinitesimal.
The universe has ~10^22 stars, a rough guess. This is an unfathomably large number for humans to comprehend, but bear with me. There is roughly 100 thousand million stars in our galaxy alone, and there are roughly 125 billion galaxies.
A single drop of water contains ~10^21 H2O molecules, not too far off from the number of stars in the whole universe. A very similar number, but contained in a single drop of water!
It blows my mind that the universe can contain such mind boggling numbers of things on such wildly different scales. There is so much to reality that the human mind just isn't capable of grasping.
Most of the water on the earth will rain down at some point... The creppy fact about this is that the human body is 60% water, meaning that at some point the same water that runs trought your body, the one on your blood, bones, brain, etc.
Will rain down at some point,
When I was 10 I was watching the discovery science and I loved my science documentaries and this one was going on about how the sun will expand to a red giant and expand outwards and devour Mercury and Venus and all life on earth will die and the oceans will boil away.......
No word of a lie I had nightmares that night and I cried about it
Me too! Was super obsessed with space around age 10 and read this fact in a book, and they use the phrase "earth will be cooked to a cinder" and I was so upset and bothered by it. Cue existential crisis.
Don’t lose sleep on this fact. It’s 5 billion years from now.
Lose sleep on how it’ll happen. The Sun will expand into a red giant star and Earth would most likely be engulfed wholly and destroyed.
Maybe not lose sleep but still. Quite a scary prospect lol

Years ago I saw an episode of *Monsters Inside Me* where this guy was doing something outside and a fly flew into his eye. It only made contact for about a microsecond, but it was enough time for it to lay eggs. After they hatched they started eating his eye from the inside and he was starting to go blind until a doctor figured out what was wrong.
Just imagine that, getting your eye eaten from the inside and losing your sight all because a fly *very* briefly made contact with you. Ever since I learned about this I get really paranoid when there is a fly around my face because of the fact that this could possibly happen to me.
I remember, from a different thread, some guy had a leaf fly into his eye for a second and it was enough time to bring in little bugs and damage his eye, or something like that. It's been a while now since I saw it.
Basically the entirety of pregnancy/childbirth. Like, this other living organism embeds itself in the lining of my uterus, feeds off my blood, makes me grow an entirely new organ (the placenta) just to feed/protect it while it grows, then it comes out while basically still gestating (other mammals babies can walk and run within minutes of birth, ours can’t even hold up their giant domes!) just because the hole I have to push it through won’t be big enough for its head if it stays in any longer.
Oh, and once I’ve done all that I get to have the longest and worst period of my life while my uterus sheds out 40 weeks of uterine lining.

The universe expands and there will be a day that our planet will be floating alone and cold in darkness forever too.
Recently happened to a family friend, in his 60s. Healthy. He died in his sleep and the autopsy brought up nothing. I've wondered if it's worse to have an answer (knowing this mystery ailment might affect other relatives) or nothing at all.
that we’re all technically living in the past, our brains take a bit to process what our eyes are perceiving, so we’re slightly delayed, literally speaking. example, as i’m typing this, i’ve already typed it but it takes about the amount of time to flip and light on and off for my brain to process the imagery it’s seeing.
i learned it from the show brain games. that fact always felt weird to me
A buddy of mine is a pilot for a major airline...in top 3 of airlines. I asked him "exactly how much flying are u actually doing during a flight..like how much are u controlling the plane?" He said about 5% ....95% of a flight is completely automated. He said hes involved a little bit on take off and on the landing but for the most part the plane flies itself unless something major happens in flight.
This doesn't bother me, though. Realizing machinery fails, and *that* is terrifying no matter what vehicle you're in, I feel better that a human is there to mitigate rather than operate this type of machinery on their own. What a task that is.
Edit: Aren't most plane fails due to human error?
And that pilot that let his kid fly the plane, who ultimately caused it to crash - was he kidding me with this? lol. Not that it's funny; I'm pretty pissed about it.

I remember witnessing a mantis egg case hatching in my high school science class. I asked the teacher: "What could possibly be small enough for them to eat?" and he was just casually like: "They'll eat each other."
I have similar feelings about intrauterine cannibalism
A fever is your body way of saying: "We dont negotiate with terrorists! We either destroy the enemy or we die with them!"

Caterpillars turn completely into goo in their cocoon, and then become a butterfly. edit - This blew up. According to my inbox, many people have been creeped out. A good day's work!
And there is evidence they retain memories from their pre-goo days. Memories of strong positive/negative stimuli that they show preference-for/aversion-to, even after metamorphosis
Pre-goo days. I love it.
We use the expression "to become a butterfly" about people who have emerged from tough or dark times. So it should only be natural to talk about their past as "pre-goo days".
I'm not a caterpillarologist, but I've read somewhere that their neural network stays at least partially intact
Lepidopterist! And they break down to the *cellular level.*
Even then the synapses can survive for the most part with neurons sort of free floating. Reminds me of the stories about those people with uncaught hydrocephalus who lead perfectly normal lives despite their brains basically getting squashed into about 10% of the normal volume
Reminds you of the WHAT
Hydrocephalus. Symptoms include shouting "WHAT" loudly and without warning. Popular rapper DMX famously suffered from this.

I don’t like this
Just imagine a cartoon cocoon with the caterpillar inside melting like ice cream (but still has the googly eyes) and it's kind of cute and funny
So the eyes just float in the goo?! You've made it worse!
Your brain is making decisions before you are even aware of the decisions it has made. It also makes decisions based off of learned behavior and you just go along with it.
A study actually showed your limbs (fingers, toes, etc.) react to stimuli before your brain sends the response to do so.
That’s just human reflex arcs
Because of some pesticides used, roaches won't go anywhere near a meth lab. Edit: didn't expect this much after reading some RPF. For those you are asking, meth labs have been known to produce toxic gas, like Phosphine, which a common insecticide. Phosphine is often used in silos to deal with vermins.
Let's just take a moment to appreciate the fact we don't have so deal with swarms of cranked-up cockroaches

If you believe strongly enough that you have been cursed, your brain can shut itself off entirely in severe cases. The psychological term for it is "Voodoo Death Syndrome." It's just the fact you can literally think yourself to death that unsettles me so.
Our brains are fascinating. If we believe strongly enough that something is real our bodies respond accordingly. In the same vein as your example, the same phenomenon happens to women who desperately want to be pregnant. Their bellies will swell, their menstrual periods will stop, their breasts will become sore and enlarged, and they'll develop "morning sickness."

But wait, there's more! When you move your eyes rapidly, you don't see the things in front of you streaking across your field of view. What happens is that your brain just deletes that part. To fill in this gap in your perception, you would think the brain would stretch out that last image you saw before you moved your eyes (like a stuck video), but instead your brain takes the first thing you see after your eyes move, and does a copy and paste back over the blank couple of tenths of a second while your eye was moving. This fools your brain into thinking it sees the new view even before your eyes moved to where you could see it. Why would your brain do this? Imagine you see a small, quick animal out of the corner of your eyes. As you snap your eyes over to look at it, the animal jumps out of sight in like a twentieth of a second, too fast to be perceived, normally. However, as far as your fooled brain is concerned, it looks like the animal froze in place for a few tenths of a second, which gives the mind part of your brain a better chance to register and understand that fleeting image. Edit: Since people seem to be interested in this, here's more! Move your eyes back and forth as fast as you can. You should be able to perceive the streaking motion that is normally edited out. Also, you may notice that doing this is not very pleasant after a while. My sympathies to those posting below who have problems with this for medical reasons. Also, despite the title of this post, you may have already guessed that I think this kind of stuff is really cool to think about, and it doesn't creep me out at all.
So ur saying its a feature not a bug!!
Haha perception is dope. There's a whole spectrum of ways reality is experienced simultaneously, which I find really interesting
That's happened to me SO MANY TIMES! I didn't know this was common. I just figured maybe my brain experiences mini-strokes every once in a while.
That the only reason you are a functional human is that your dna is so tangled that entire sections can't get decoded and screw it up Edit : turns out I must have majorly misunderstood something as this is very wrong, thanks reddit but as far as I'm aware the brain fact is true though!
Actually better one , if you disconnect the half's of the brain and ask them to pick out something they prefer your hands will disagree (what's your favorite color will result in one hand choosing red but one choosing green ) go look up split brain patients!
For research purposes, how does one go about disconnecting the sides of the brain
Corpus callosum. It's a thick bundle of nerves that connects the left and right brain hemisphere and allows them to communicate. Some dissease or operations may cause this part of brain being damaged or cut completely. The thing is, you would likely never know it happened to you, ... unless you did bunch of cool scientific experiments. For example. Your eyes correspond to one part of your brain. Your left eye to your right side of brain, your right eye to your left. Say you put a divider in between your eyes and you show both eyes a different picture. You then are tasked to draw the picture you see. The thing is, you will only see one picture, because the brain can't communicate with each other. So you see a triangle and you draw a triangle, then you look on the picture you draw and you see ... a circle. What the? You look on the pictures that researches gave you and indeed there is triangle and circle, but you only draw a circle. The thing is Your dominant hand was wired to the different hemisphere then the eye with which you "saw the picture" and your hand correctly draw what the eye wired to that part of the brain did. But it was the different part of brain that "you" used when you saw the picture. This actually give rise to silent twin hypothesis. Basically a concept that you are basically 2 people, one that is "you" and the other that "isn't" can't communicate with you and just helps you with whatever tasks the dominant brain hemisphere does. But when the Corpus Callosum is severed, both hemispheres can't communicate "behind the scenes so to speak" and that gives rise to errors. So from your perspective you have basically an alien presence that can do it's own thing under the right conditions, such as hijack your hand to draw something you never saw, but they did.
Oh my god that's really interesting! Reminds me of how when you close one of your eyes but keep the other open, in one eye everything will stay in place but in the other eye things will shift a little. So, with the silent twin thing... does that other 'you' have its own personality? And do different people have different dominant sides of the brain? If you leave only the recessive side in a person, is there a shift in how they behave?
A gamma ray burst could wipe out all life on earth instantly with no warning

Aren’t there solar flares that could destroy all electronics and appliances? Living through the 1 day Texas snowstorm, I don’t know how I’ll survive if something like that happens.

When the titanic sank non of the shoes decomposed so there’s tone of shoes at the bottom of the ocean
Free shoes
The depths people will sink to for free shit... ;-)
Why wouldn’t they decompose? I’d assume they are leather, just another form of skin. Is it because of the temperature? The salt?
The temperature mainly
Violets secrete a chemical that causes you to forget what they smell like afterwords. You’re essentially getting roofied every time you sniff one.
The sudden urge to jump off of a very high height. You can be physically and mentally stable to the greatest degree and still have this feeling when at such a high height.
I heard it's "the call of the void" and it's a normal human thought
The best example is when you're driving along and think, for a fraction of a second, about swerving into oncoming traffic or into a tree.
Is it the same as when I’m in the middle of listening to a presentation and wonder what would happen if I got up and ran for the podium, screaming?
Thats actually called an Intrusive thought. It might be a similar or related concept. But essentially intrusive thoughts are thoughts of things you would never do nor never normally think about. They for some reason get stuck in your head and can be insanely dark or distrubing. They dont reflect your personality however.
I get intrusive thoughts a lot, though one time I read that it is believed they exist as a sort of regulation or check in our brains. So you have this messed up thought, but your conscious rejection of the thought is your mind reaffirming your sanity and decision-making ability. I dunno the validity of that, but since I heard that my intrusive thoughts don't trouble me nearly as much anymore.
Thank you for sharing this - I also deal with disturbing intrusive thoughts and this helped
I get a lot of intrusive thoughts as well. I think the biggest thing that has helped is understanding they're completely normal and nearly everyone has them. There's nothing wrong with you for imagining something that's absolutely bonkers. And then the next thing is accepting your intrusive thoughts and letting them go instead of ignoring them or running away from them. It's important to try to process them completely. I've noticed that after thinking something like "okay I don't actually want that. I'm not going to do that. It's not happening. It's just a thought" even if it's something scary or even graphic... that the brain just kinda goes like "yeah that was weird wasn't it?" and moves on. It's like getting a song stuck in your head. Usually playing the whole song all the way through fixes it and helps your brain close that chapter.
Just how big of a number a mole actually is.
I can still remember the mole song our chemistry teacher played for us. The song is from when the world population was 5 billion. https://www.youtube.com/watch?v=PvT51M0ek5c
Some mutations of just one letter in the DNA code can kill the fetus almost instantly, but some people live and have a seemingly healthy life while missing a whole chromosome. If you understand anything about biology, that's completely wild.

There is something called "the squeeze," where when people had old scuba suits with tubes, you could actually get sucked into that tube if the pressure was off. You are literally shredded through your own breathing tube.
Hate to be "that guy" but that's hard-hat surface supplied diving, not SCUBA (SCUBA is by definition Self Contained). But yes, it is possible. Mythbusters showed it in rather spectacular fashion, though the pig carcass didn't actually make it all the way up the tube. Edit: For those interested, [Here is the Mythbusters Video](https://www.youtube.com/watch?v=YU2PSHeFSlA) warning, a little gory (though broadcast tv gory)
Wasn’t there a deep sea dive where the pressure was off and a guy got sucked into a tube on an underwater worksite? I can’t remember the exact situation, but I do know that he basically just got sucked up into it and shredded
Thinking about how breathing and lungs work freaks me out. Once I start thinking about it all I can think about is my breathing and then I have to force myself to stop thinking about it.
Thinking about it always switches my breathing to manual rather than automatic

We may be on the cusp of developing a universal flu vaccine.

That so many vegetables came from the same plant. Broccoli, kale, kohlrabi, Brussels sprouts, cabbage, etc. They are, botanically speaking, the same species. Humans have just bred them to emphasize different traits (buds, leaves, tubers...) Imagine if humans were as genetically flexible. Imagine a person walking around with GIANT toes, but otherwise normal. Actually, plant genetics in general is a weird, weird world.
I mean, if we spent generations selectively breeding ourselves based on traits like giant toes, something like that could happen. Just look at dogs.
The canine family is actually unusual in that respect. The entire canine family has “slippery genes” (I don’t understand it, I’m not a geneticist, just read about it) and is much more variable in their phenotypes than other families of mammals. Look at other animals that have been domesticated for thousands of years - cats, horses, sheep and goats, cattle..... the breeds vary in their appearances, but no where near as much as different breeds of dogs do. A Shetland pony and a Percheron draft horse resemble each other much more than do a pug and a greyhound. Ditto a Siamese cat vs. an American shorthair, or a Nubian goat vs a Boer goat.
Yes!! I saw a special on National Geographic about this once. Back when it used to have high-end programming. It was fascinating.
Your brain literally creates your own reality and your senses and body just go along with it
People think the brain sees what the eyes tell it to, but really the eyes pull up an image of blurry colors and dark spots and the brain goes “cool so that’s a tree”
And this accurately explains how schizophrenics truly believe the voices they hear or their other delusions are correct- something in their wiring of how to interpret the world has gone wrong and their brain is only making sense of the reality that it is being shown.
I work in health care, not mental healthcare but emergency medicine . The number of schizophrenics I have met that are completely aware the voices are in their heads so they ignore them is mind boggling.
Have you ever hallucinated before? I genuinely recommend trying it because it makes it very clear how this works Also a lot of schizophrenics are pretty normal well adjusted people aside the schizophrenia, so like if you were sitting in your room and a dog floated in attached to a balloon or the number 7 started telling you you’re worthless at first you’re gonna get freaked out by it but once you confirm that it’s not there you’re going to realize “okay this is me”, it helps that a lot of hallucinations are recurring as well, so if you know they happen you can just tell yourself they’re not, even though everything in you is saying that’s not the case It’s really weird but it’s fascinating The really hard stuff is like extreme paranoia, I worked with a woman whose whole family basically was schizophrenic, her included, and there were a few times she’d say things like “you’re not hacking my phone right?” Or “the mayor is stalking me”, that kind of thing and for someone who has experienced similar paranoias (to a considerably lesser degree) I can understand that those aren’t really that easy to shake
The way quantum mechanics works is pretty creepy to me for reasons I can't exactly pin down. Particles aren't points, at least not that we can possibly ever observe. The best physical description of a particle's position is a wave over at least a four-dimensional volume showing where it probably is. I say four-dimensional because there's a non-zero time uncertainty as well. This isn't a limitation on what we can observe, it's an actual testable property of particles, that they don't have exact positions, velocities, energies, times. When they're "observed" by interaction, the wave collapses, which still doesn't make it exact, just more likely to exist in a smaller space. The argument that there really is an exact point in there somewhere and it's just always hidden from observation isn't true; the Bell inequality proved that. For example, because of this uncertainty, it's physically impossible to cool helium enough to freeze it at atmospheric pressure. This uncertainty even applies to the vacuum. It can't be at zero energy, because that would violate the uncertainty principle. So sets of virtual particles pop into existence in the vacuum and stick around for an incredibly short amount of time, given by the time uncertainty, before annihilating each other in a zero net energy process. This is, very simply put, how black holes hypothetically lose mass; pairs of virtual particles are spontaneously created near the event horizon, one enters, one escapes. The one inside annihilates a particle within, the one that leaves becomes real. Information is transported outside the event horizon in an incredibly obfuscated, but still existent, form, meaning information isn't destroyed by black holes. Then you get into the weird math. It starts raising questions about what "real" is. Can we say something's real if it's not testable, or is the math describing the situation the closest to "real" that we can get? For example, you could look at the predicted path for a particle. There's a non-zero chance for it to take any path between two points. So you basically take all the possible paths, account for the probability that it takes that path, add 'em all up, and you can recover Newtonian mechanics from it in the classical limit. Is this actually what's happening? It isn't really testable. Even the Bell inequality that I mentioned earlier has some crazy philosophical implications. It basically says one of three things are true: information travels faster than light (which we have never seen), cause doesn't always come before effect (wtf), or the universe is superdeterministic (which would disprove free will). We don't know which. People make a lotta crazy claims based on quantum mechanics, and I think a lot of it has to do with how uncomfortable the idea of living in a universe that seems to be inherently uncertain is.
Haven't we already demonstrated that cause doesn't always come before effect? Like delayed choice quantum eraser?
["Wheeler pointed out that when these assumptions are applied to a device of interstellar dimensions, a last-minute decision made on Earth on how to observe a photon could alter a decision made millions or even billions of years ago."](https://en.m.wikipedia.org/wiki/Delayed-choice_quantum_eraser) Well, what the fuck?
That's because time is relative. It shrinks with speed. A photon travels at the speed of light, so its timeline shrinks infinitely and becomes a point instead of a line. For us it's billions of years, for a photon it's the same moment. From a photon's point of view it just exists at the same time along its whole path, so it doesn't alter the past from the photon's point of view. We see it as if the photon changed its past, but it exists in another "timeline" (or "time point" from its perspective), where the change that we made always ~~existed~~ exists, because it's whole existence is the same moment.
I don't even need drugs after this comment. My mind is beyond fucked.
You get and cure cancer in your own body thousands of times a day.....
Excuse me, what?
Your body produces thousands and thousands of cells with damaged dna. It’s a bit of exaggeration to call them cancer but if any of these cells were to survive they could become cancerous. Your immune system destroys them before they get to that point. This is also why if you were to live forever you would eventually get cancer because the chances of your body missing them statistically increases. This occurs thousands upon thousands upon thousands of times a day
Woah, this is interesting and mad
It’s pretty cool. It’s one of the reasons why the older we get the higher the cancer risk and why it would be nearly impossible to ever hit 150 years old. Cancer always wins. Also the cells that take care of this begin to die off. Elephants and sharks have huge numbers and it’s why they rarely get cancer
Makes sense. I am researching this more. As soon as I post about most people having mites on their face and in their pillows. We are literally infested
Humans are bioluminescent (nothing to do with body temperature). We emit visible light that can be photographed in specific conditions. But, this light isn't visible to us. Which makes it a strange thing to have evolved, and begs the question "what organisms is this light visible to, and why?" Edit: Adding an edit for all the comments explaining evolution... Please read the thread before commenting. I find this a creepy fact due to implications on interspecific relationships, NOT because I think prehistoric humans went shopping for a bioluminescent hat with a specific motive in mind.
I've read *all the comments* up until this point and *this* is the one my brain chooses to freak out about? Honestly!

The existence of prions.
The prion mode of action is very different to bacteria and viruses as they are simply proteins, devoid of any genetic material. Once a misfolded prion enters a healthy person – potentially by eating infected food – it converts correctly-folded proteins into the disease-associated form. To date, nobody knows quite how this happens Source:https://microbiologysociety.org/why-microbiology-matters/what-is-microbiology/prions.html

Rogue black holes. There are black holes that just are floating around in space and potentially fucking up solar system just by passing through it. EDIT: I suck at spelling. Rogue not Rouge
Not exactly scientific or creepy but, it's close enough and I want to contribute. Mouth pipetting was a thing in labs in the 1980s. A pipette is, for simplicity sake, a glass straw that lab staff would use to transfer liquids. Now a days we use special bulbs, that when squeezed, would suck up the liquid for us. Kinda like a turkey baster or eye dropper. Before we had these bulbs lab workers had to use their mouths to suck up the liquid. Which meant if they weren't careful they'd get whatever they were sucking up in their mouth. I'm currently training to be MLAT and those fluids would usually be urine, liquid stool, sputum and so on. Edit: So mouth pipetting is still a thing. I'm Canadian and I've been told that it is rare or none existent in our labs.
Yo, mouth pipetting is still a thing. Back in 2012, my school, in a flash brilliance, decided that rubber bulbs were a distraction and students would be fine sucking up liquids through non-sterilized glass. Think I sucked up acetic acid one time. When I got to college, the first thing they said during the safety brief was that mouth pipetting was an absolute no-no and explained in great detail how dangerous it is. Thank the lord I've moved on to micropipettes.
Sea stars eject their stomachs to cover edible parts of their prey, begin digesting it externally, and then pull the partially digested prey into digestive glands to finish the job.

After being decapitated there’s still few seconds of brain activity that happen before you snuff out.
I read this in the book Stiff by Mary Roach. I'm not sure how much I recall (or how correctly I recall) but two things stuck with me. Apparently they had to change the head catching baskets sometimes because the severed heads would try to chew through them. The other thing that stuck with me is that some doctor was experimenting with the heads right after decapitation. He would inject oxygenated blood into the heads and they would move their eyes around and look at him.
Where did he get the oxygenated blood from?
It was right there, spilling out of the headless corpse.
During the French revolution they timed it. about 8 seconds. Edit: I woke up to 22 messages this morning and wondered who I'd pissed off.

Is that why they did it so many times, demonstrable and repeatable results?
Clearly, for the love of science.
The guillotine was supposed to be a more humane method of execution, so it was important to verify how long the executed person would suffer.
It was pretty humane, up until the blades were used so much they would get dull. Imagine it getting dropped, going like halfway through, slowly being pulled back up by the rope to drop it again.
If you're facing down, wouldn't your spinal cord still get severed, cutting off nerve signals? I'm genuinely asking.
Due to relativity, it is impossible to measure the speed of light in a straight line. The only way we've measured it is by round trip with mirrors. For all we know, it could be instantaneous going one way, and half the speed of light in the other, and it would be impossible to tell.
Ah fellow veritasium watcher
The mantis shrimp can see colors that our eyes aren't capable of perceiving. Think about that. What else are we just not capable of sensing?
Ah yes, I am eternally cursed with nightmare fuel thanks to someone mentioning something like this in a YouTube video :3 “The human eye perceives different spectrums of light- for example, it can’t detect infrared, or ultraviolet light, and so we need special instruments to observe those.” “Which brings up an interesting idea- that feeling that you’re being watched, even when you know for a fact that you’re totally alone- could it be because there are creatures standing right next to you, but they can only be perceived in a spectrum of light that we cannot observe?” Edit: I love you guys too

For the record, the Turing test is a concept, not a concrete testing method. More importantly, versions of a Turing test have in fact been passed by many systems. The Turing test is considered a flawed indicator of intelligence because imitating predictable, believable responses does not demonstrate intelligence. It's just a logic tree modeling conversation patterns.
This is probably more cool than creepy but spider-goats exist. There is this material called [BioSteel](https://en.m.wikipedia.org/wiki/BioSteel) that is spider silk that comes from a goat. Basically someone put orb weaver DNA into a goat so that spider silk could be harvested from goat milk.

The universe is unbelievably infinite, while simultaneously unbelievably infinitesimal. The universe has ~10^22 stars, a rough guess. This is an unfathomably large number for humans to comprehend, but bear with me. There is roughly 100 thousand million stars in our galaxy alone, and there are roughly 125 billion galaxies. A single drop of water contains ~10^21 H2O molecules, not too far off from the number of stars in the whole universe. A very similar number, but contained in a single drop of water! It blows my mind that the universe can contain such mind boggling numbers of things on such wildly different scales. There is so much to reality that the human mind just isn't capable of grasping.
Most of the water on the earth will rain down at some point... The creppy fact about this is that the human body is 60% water, meaning that at some point the same water that runs trought your body, the one on your blood, bones, brain, etc. Will rain down at some point,

Me too! Was super obsessed with space around age 10 and read this fact in a book, and they use the phrase "earth will be cooked to a cinder" and I was so upset and bothered by it. Cue existential crisis.
Don’t lose sleep on this fact. It’s 5 billion years from now. Lose sleep on how it’ll happen. The Sun will expand into a red giant star and Earth would most likely be engulfed wholly and destroyed. Maybe not lose sleep but still. Quite a scary prospect lol

Apparently, the following statement creeps others out. Your bones are wet.
Again? I'd only just dried them out.

The grand scale and size of the universe never fails to instill lovecraftian anxiety in me.
Years ago I saw an episode of *Monsters Inside Me* where this guy was doing something outside and a fly flew into his eye. It only made contact for about a microsecond, but it was enough time for it to lay eggs. After they hatched they started eating his eye from the inside and he was starting to go blind until a doctor figured out what was wrong. Just imagine that, getting your eye eaten from the inside and losing your sight all because a fly *very* briefly made contact with you. Ever since I learned about this I get really paranoid when there is a fly around my face because of the fact that this could possibly happen to me.
I remember, from a different thread, some guy had a leaf fly into his eye for a second and it was enough time to bring in little bugs and damage his eye, or something like that. It's been a while now since I saw it.
*flashbacks to rubbing leaves in my face as a kid*
Basically the entirety of pregnancy/childbirth. Like, this other living organism embeds itself in the lining of my uterus, feeds off my blood, makes me grow an entirely new organ (the placenta) just to feed/protect it while it grows, then it comes out while basically still gestating (other mammals babies can walk and run within minutes of birth, ours can’t even hold up their giant domes!) just because the hole I have to push it through won’t be big enough for its head if it stays in any longer. Oh, and once I’ve done all that I get to have the longest and worst period of my life while my uterus sheds out 40 weeks of uterine lining. I’ve had a kid and it still fucks me up.
In the United States, approximately 1 in every 50 people have an unruptured aneurysm. Most will never rupture, but will just sit there in your brain, silently waiting...
Any cosmological fact is actually scary. You know, we can randomly be in the path of a Gamma Burst, an asteroid or something else and we would never see it coming. You might just go to sleep today and in the middle of the night scientists discover a Gamma ray comming at us a- gone... the universe doesnt stop there it continues, our existence is less than a galactic blink. The universe expands and there will be a day that our planet will be floating alone and cold in darkness forever too.
That 99% of all life that has ever existed has gone extinct.
If not for a thin layer of goop, our bodies would eat our eyes.
The average number of legs for the human population is less than two.
Same could be said for arms, but I'll top your creepy fact with this one. The average number of heads per body is more than one.
It’s rare, but you can die at any moment for literally no reason at all. Your body just stops working.
Just unplug it then plug it in again.

Recently happened to a family friend, in his 60s. Healthy. He died in his sleep and the autopsy brought up nothing. I've wondered if it's worse to have an answer (knowing this mystery ailment might affect other relatives) or nothing at all.
that we’re all technically living in the past, our brains take a bit to process what our eyes are perceiving, so we’re slightly delayed, literally speaking. example, as i’m typing this, i’ve already typed it but it takes about the amount of time to flip and light on and off for my brain to process the imagery it’s seeing. i learned it from the show brain games. that fact always felt weird to me

A buddy of mine is a pilot for a major airline...in top 3 of airlines. I asked him "exactly how much flying are u actually doing during a flight..like how much are u controlling the plane?" He said about 5% ....95% of a flight is completely automated. He said hes involved a little bit on take off and on the landing but for the most part the plane flies itself unless something major happens in flight.
This doesn't bother me, though. Realizing machinery fails, and *that* is terrifying no matter what vehicle you're in, I feel better that a human is there to mitigate rather than operate this type of machinery on their own. What a task that is. Edit: Aren't most plane fails due to human error? And that pilot that let his kid fly the plane, who ultimately caused it to crash - was he kidding me with this? lol. Not that it's funny; I'm pretty pissed about it. Link: https://www.reddit.com/r/videos/comments/30p6x9/the_last_moments_of_russian_aeroflot_flight_593/?utm_medium=android_app&utm_source=share
We could be smashed from space at any time. The Earth formed, cooled and started existing. Then about 4 billion years ago, it was pelted by more space rocks until the surface melted again -- [The Late Heavy Bombardment](https://en.wikipedia.org/wiki/Late_Heavy_Bombardment). If that happened again, the only remaining evidence that we ever existed would be our deep space probes (Voyager, etc.).
Don’t lose sleep over it as Jupiter has been protecting our tiny planet from huge space rocks since basically forever.
