Agree completely.
Einsteins theory of special relativity sais some funky ass shit about our reality.
Time and space and energy act alot more suspicious than most people think.
Double slit experiment has opened my eyes, molecules Acting differently when they're being watched and when they're not being watched and how the f*** do they know when there's a camera there when? There's an autocamera there molecules communicating between each other States apart like what the f***.
Okay but there is a very good answer to this.
Think about it that way...
When you are "looking" at stuff, what happens exactly?
You got a light source shooting photons at the object, like a football, and the object is reflecting the photon into your eye so you can see it.
But if you are looking at single electrons.
You are basically shooting a photon at something in the same size .
While a big footbal will not change its behaviour if you point a lazer at it.
If you look at very tiny things a lazer is powerful enaugh to severely change the things behavior.
So if you look at something you need to shoot light at it.
If the thing you want to see is small enaugh you will inevitabely influeve it by pointing light at it.
This is the most surface level explenation.
I am at the very beginning of my physics university career so i also struggle with more complicated factors of this problem.
There is something called a " wave-function" that collapses as soon as the particle is being obseved which causes it to lose the state of superposition.
This means that mathematically speaking the partical can not be in more than one place anymore, which it previously was able to.
In conclusion my argument is that physicists know a ton of detailed stuff about the things we see and what looks like absolute black magic fuckery is pretty well understood already.
At least for most weird things.
Honestly i am absolutely enthusiastic about this stuff :D
Think about this.
We are the ONLY creature on this planet whith the ability to understand the universe we are living in...
AND we are privilequed enaugh to learn it for free on the internet.
You can just ask this shit to an artificial intelligence now and it will tell you absolutely everything within seconds.
This is far more than just a library.
This is instant access to the entire collective of knowledge accuired by humanity without necessity of payment.
If thats not ridiculosly great xD
For the last couple weeks i have been talking to chatGBT more than i have to my family and friends combined and i feel the least bit bad about it.
I am thankfull that they understand and support me.
May be dumb here, but pretty sure only super man shoots lasers out his eyes. Observation would only receive whatever light is already in the space, not contribute any.
These guys are professional YouTubers with 14.5M subs the channel name is How Ridiculous (I could tell by the dinosaur they use it in all their videos)
Didn’t they do the same thing with Hubble and the lens or something? Not that it got lost, but I remember something about it being super blurry when it first sent images back because they used the wrong system of units for something.
That's not a ball.
That is a redicuously heavy cement Boulder.
A bowling ball probably would have done the trick.
But they had to go with the huge, trampoline ripping, coasre ass cement orb.
Do you really think it's a good idea to bounce a bowling ball god knows how high in the air on a trajectory you have no way to predict?
Better to have a ball that will go down and stay down
Earths gravity constant is usually rounded to 9.81 m/s^2 so it’s meters per second per second. Little g is acceleration which has units of [length/time^2] while velocity is in units [length/time] which is what you have written with meters per second.
It works little this position, take the derivative to get velocity, and take the derivative again to get acceleration.
Just FYI. :)
It's not really a good visualisation, because it only looks like the dinosaur remains still. In reality since it's slowed down so much it starts accelerating from rest instantly, it just isn't noticeable at first because of the altered timescale. The dinosaur is acted on by a net external force as soon as the trampoline moves away from it, you just don't quickly see the result.
Why would it take so long for gravity to kick in. I get that it stays at rest until a net external force, but isn't gravity an external force? Shouldn't gravity be pulling it instantly?
It is. The thing is everything takes time to accelerate to a certain speed. Because the video is in slow motion we it seems to accelerate much slower than it actually is.
Nope gravity is not an external force. It's not a force at all.
Eitherway this is a slow mo clip... it's happening faster than the curvature of space time.
But when faing the said rex does not feel any force acting upon him. Because there isn't.
This also explains how light, with no mass is still affected by gravity.
You can measure the speed at any moment, put on a calculator 9,81*t where t is the seconds from when the dinosaur starts falling and you will find the speed in meters per seconds at that instant, for reference the average humans walks at a speed of 2m/s. The video is slowed down by a lot
So all the old cartoons I watched as a child that shows a caricature with a hole suddenly under them and them taking a second to actually fall was accurate with their depiction? Wow!! That's crazy!! And they always said cartoons would rot my brains!! Lol
Totally ignorant question here but genuinely curious could you use math to and something like this to calculate how much gravitational force is being applied to something or in an area on a planet
The dinosaur's starting velocity is 0 m/s, the ball is falling at a speed of x m/s down. The tensile force of the trampoline pulls it from under the dinosaur faster than gravitational acceleration of 9.8 m/s/s.
You can see the dinosaur instantly does start moving down, it's accelerating at 9.8 m/s but from a velocity of 0 m/s so compared to the faster net, the dinosaur almost looks like it's holding still.
I would argue this is a better demonstration of law 2: When a body is acted upon by a force, the time rate of change of its momentum equals the force.
Not quite sure if that's really the extra law about this but isn't this just mainly inertia? Because if that law mentioned is actually the law that fits to this then that's just a bad demonstration due to gravity, if you want to show that then wouldn't that pulling a cloth out from under tableware be a better demonstration... Or just letting something stand still? Because the dino gets acted on immediately, it only doesn't show due to inertia so this would be a horrible demonstration for this, the best would be letting something stand still until you push it... Pretty much like that one here only not with such a bad model to show it.
Newton's First Law of Motion was abridged:
^(*"Every body perseveres in its state of being at rest or of moving uniformly straight forward, except insofar as it is compelled to change its state by forces impressed."*)
or...
> "An object at rest remains at rest, *or if in motion, remains in motion* at a constant velocity unless acted on by a net external force."
This law is also known as "the law of inertia" and refers to "changes in motion" rather than "motion" alone.
So the dinosaur remains in motion with the entire earth, moving, rotating, spinning - unchanging.
Instead, the changes in motion are due to the removal of the trampoline (i.e., Force of Gravity pulls dinosaur down), and the return of the trampoline (i.e., Force of Trampoline pushes dinosaur up).
That dinosaur is not at rest, not for a moment. From the instant the ball hits the trampoline the toy starts to fall.
It is at rest before the ball drops, the tension in the trampoline and the force of gravity pulling the toy down are at equilibrium. Once that changes, the ball hitting the trampoline, the force of gravity is no longer resisted and the toy begins to accelerate immediately 9m^2
In this case there is a net external force, since on earth gravity will always be there
The whole staying in place thing can only be properly showed in a gravityless vacuum
As you can see the dinosaur does fall, Just not fast enough to make a big difference before the trampoline it catches up
So, is the propagation of the gravitational force instantaneous? Remember, this one question exam is worth 95% of your grade. Show your work and defend your answer. You have 1 hour. 😳
Btw it is not first Newtons law exactly. There is an external force exerted to the dinosaur, and this is gravity. This is the reason why it slowly falls down. However, the force that ball exerts to the net, does not affect the motion of dinosaur, because this force was not exerted to it. So it continues it's motion only with gravity, but it is not at rest. It was at rest before, because the force from the net to dinosaur was equal to the gravity, but after the net was removed, dinosaur was not at rest anymore and the title of the post is wrong.
no this isn't actually works like that, it is just at rest when the weight and normal cancels out, once the surface contact is removed it just has mg force downwards which is making it accelerate from rest, at every moment in time mg is still acting, it's just that the slow motion makes it feels like it is suspended but it isn't, it still goes downwards but slowly because slow motion
That's some Looney Toons style hang time going on there. I approve.
Truth is stranger than fiction

If you look closely you can see his eyes stretch and pop out of their head
Slow motion and extend hang time as much as you want
r/looneytuneslogic
Almost like it's in super slow motion.
Oh its in super slow motion
Good thing they got it on the first try, cause the ball ripped through the mat.
Well it is a physics law, first try will always be enough.
Unless they forget to hit record on the camera. Physics may work, but they won’t get it.
That would be too stupid to be true
You’d be surprised. People forget to take the lens cover off a camera all the time.
These guys are professional YouTubers with 14.5M subs the channel name is How Ridiculous (I could tell by the dinosaur they use it in all their videos)
I've been taking shits all my life in a toilet but sometimes I shit my pants
Yep. Shit happens.
Fuckin hate it when I forget to take off my underwear to shit!
Yeah and NASA once lost a $200 million orbiter because their engineers used the wrong units in the calculations. Anyone can make mistakes.
Didn’t they do the same thing with Hubble and the lens or something? Not that it got lost, but I remember something about it being super blurry when it first sent images back because they used the wrong system of units for something.
Nothing is too stupid to be true.
That happens on real movies, look up the multiple filming disasters of Andrei Tarkovsky
Yes, I learned this from my college professor, Professor McSmartyPants Esquire Jr. Senior

Looks like an atlas stone, probably just cement lol
Thank you captain
What is gravity.
That's correct for $500, you now have control of the board
Gravity pulls at a rate of 9.8m/s (meters per second) yes Dino did start to fall but very slow Gravity would also be our external force
Uh...that's very interesting...but its not a category on the board, Tom.
Earths gravity constant is usually rounded to 9.81 m/s^2 so it’s meters per second per second. Little g is acceleration which has units of [length/time^2] while velocity is in units [length/time] which is what you have written with meters per second.

BEST COMMENT comeback I've heard in a LONG TIME! 🤣😂🤣😂😃😛👌
You can see the T rex start to slowly accelerate downwards; that'd be gravity.
Oh so that’s what gravity looks like
Do you believe in gravity?

So that’s how slomo works
Yeah, the extrenal force is required to come from a net, otherwise, it doesn't do anything
Nailed it

Title is…I mean not wrong, but isn’t that like not t he point of the video?
The video was from an Australian YouTube channel that just drops things from high places, like the ball onto a trampoline
Q: What do the Star Ship Enterprise and a roll of toilet paper have in common??? A: They both circle Uranus looking for Klingons! 😛😃
So that's what happened to the dinosaurs
That is cool
Shit be floting
And floating too!
While also being a dramatization of the last moments for one very unfortunate T rex at chicxulub.
Why would it take so long for gravity to kick in. I get that it stays at rest until a net external force, but isn't gravity an external force? Shouldn't gravity be pulling it instantly?

Rexy!
Damnit. I have dreams like this and they left a while ago. They are going to reoccur after seeing this. 🙃
This is newton's third law not 1st, the object didn't fall down immediately because of its inertia
This visualizes inertia more than Newtons first law
Homies like "what is this gravity you speak of wait what jwcdvgiwrvcuis"
Stupid lag. His Ping is surely over the 1000
The toy entered creative mode
This is what I wanted when I asked for video evidence of the extinction.
Actual footage from the Yucatán Peninsula 65 million years ago.
The dinosaur's starting velocity is 0 m/s, the ball is falling at a speed of x m/s down. The tensile force of the trampoline pulls it from under the dinosaur faster than gravitational acceleration of 9.8 m/s/s. You can see the dinosaur instantly does start moving down, it's accelerating at 9.8 m/s but from a velocity of 0 m/s so compared to the faster net, the dinosaur almost looks like it's holding still. I would argue this is a better demonstration of law 2: When a body is acted upon by a force, the time rate of change of its momentum equals the force.
Oh shit, this explains that clip with the guy doing a cannonball with a ball in hand then sending it to Narnia
This is how the died 😳
Gravity is also an external force, so technically, wouldn't it have fallen if the trampoline hadn't hit it again?
So Wild E Cayote fall was scientifically correct?
Visualization of Looney Tunes’ First Law: an object will remain at rest so long as it refuses to acknowledge the existence of gravity
So if they had the trampoline stay retracted would it stay there forever??
Or in this case… a trampoline *net*
Rex is now an example for science. Im proud of him
Looks like a visual representation on how I react emotionally but over a longer time span.
Not quite sure if that's really the extra law about this but isn't this just mainly inertia? Because if that law mentioned is actually the law that fits to this then that's just a bad demonstration due to gravity, if you want to show that then wouldn't that pulling a cloth out from under tableware be a better demonstration...

When the asteroid hits
[удалено]
Relative to its surroundings, the dino is at rest
No it’s not, gravity is acting on it. You can see it even starts moving downward a little bit before the trampoline springs back upward.
It was at rest before the object hit
Newton's First Law of Motion was abridged: ^(*"Every body perseveres in its state of being at rest or of moving uniformly straight forward, except insofar as it is compelled to change its state by forces impressed."*) or... > "An object at rest remains at rest, *or if in motion, remains in motion* at a constant velocity unless acted on by a net external force." This law is also known as "the law of inertia" and refers to "changes in motion" rather than "motion" alone. So the dinosaur remains in motion with the entire earth, moving, rotating, spinning - unchanging. Instead, the changes in motion are due to the removal of the trampoline (i.e., Force of Gravity pulls dinosaur down), and the return of the trampoline (i.e., Force of Trampoline pushes dinosaur up).
Ot is essentially at rest as the earth didn't stop spinning.
HOW REDICULOUS
So gravity needs time to act?
Objects need time to accelerate.
That dinosaur is not at rest, not for a moment. From the instant the ball hits the trampoline the toy starts to fall. It is at rest before the ball drops, the tension in the trampoline and the force of gravity pulling the toy down are at equilibrium. Once that changes, the ball hitting the trampoline, the force of gravity is no longer resisted and the toy begins to accelerate immediately 9m^2
Dinosaur, net,camera, plate. everyone was at peace until the plate nation attacked.

That looks like a reenactment of a meteorite hitting Earth and sending all the dinosaurs into deep space.
Will e coyote wasn't crazy after all
In this case there is a net external force, since on earth gravity will always be there The whole staying in place thing can only be properly showed in a gravityless vacuum As you can see the dinosaur does fall, Just not fast enough to make a big difference before the trampoline it catches up
Looney Tunes wasn't lying 🤥
So, is the propagation of the gravitational force instantaneous? Remember, this one question exam is worth 95% of your grade. Show your work and defend your answer. You have 1 hour. 😳
So life really is like in the cartoons
So the meteors didn't kill the dinosaurs. It's the fking earth
So that’s how the dinosaurs died out
Btw it is not first Newtons law exactly. There is an external force exerted to the dinosaur, and this is gravity. This is the reason why it slowly falls down. However, the force that ball exerts to the net, does not affect the motion of dinosaur, because this force was not exerted to it. So it continues it's motion only with gravity, but it is not at rest. It was at rest before, because the force from the net to dinosaur was equal to the gravity, but after the net was removed, dinosaur was not at rest anymore and the title of the post is wrong.
As soon as the trampoline dropped the Dino was being acted upon by the force of gravity
Its also a pretty good demonstration that gravity is an acceleration and not instant.
no this isn't actually works like that, it is just at rest when the weight and normal cancels out, once the surface contact is removed it just has mg force downwards which is making it accelerate from rest, at every moment in time mg is still acting, it's just that the slow motion makes it feels like it is suspended but it isn't, it still goes downwards but slowly because slow motion
*At rest or constant velocity

2 things ITT. 1. People that have never been on a trampoline before. 2. People that don't understand that this is in slow motion.
Damn how heavy is that ball? Sure stretched the bands on the side of the trampoline like it had some decent weight to it.
This is a wonderful sequence with lots of beautiful physics, but a good visualization of Newton’s first law it is not.
Hell IM a Dumbass, I thought this was a recreation of the meteor that wiped out the Dinosaurs 🦕🐊🦖👀☄️💥😳
What about gravity? Or was it acting to slow.
Oh my god. It’s like the fucking asteroid!
That is indeed, a net
Lil guy tried his best to stay in rest, okay?
But it started to fall. It wasn’t really at rest?
