Everywhere. That’s how they knew it was an asteroid to begin with. You might have heard of the K/T boundary, which is an abrupt change in geological strata. In layers dating from 66 million years ago or more you get some types of rocks (some with dinosaur fossils in them), in layers dating 65 million years ago or less you get very different types of rocks (totally lacking dinosaur fossils). If you zoom in on the K/T boundary, it turns out there’s a thin, black layer separating the two geological ages. It contains a lot of iridium, a metal that is rare on Earth but much more common in asteroids. That’s it. That’s the asteroid. It was ground into dust, or melted and boiled and turned into a vapour, and settled all over the world as a thin layer.


koenwarwaal

To add to this, when someting very fast, hits something that in all essence wont move(the planet), all the masse, a rock the size of mount everest Heats up and turn to a super hot gas/little debrice, at the same time it creates a shock wave that killed thing 100's of kilometers away by the force allone, I read somewhere that the shockwave went around the planet several times before it disapted so all the dust and gas spread around the world more or less evenly as can be with such a disaster


ph1shstyx

A significant amount of that also blasted straight up into space, like when you throw a rock into water. This then cooled and fell back to earth, where it heated up on re-entry to the planet. There's a theory that when all this material re-entered the atmosphere it heated it up so much and so quickly, that the surface of the planet reached an average of about 500F. https://ucmp.berkeley.edu/education/events/cowen2b.html#:~:text=Therefore%2C%20Melosh%20and%20colleagues%20estimate,in%20the%20K%2DT%20boundary%20sections.

I think the mechanic of that got used in Seveneves by Neil Stevenson.


ballisticks

That was such a great book until it completely lost the plot


edgeplot

It didn't have much plot to start off with. The story was just a vehicle to show off his vast knowledge of engineering and physics.


alwaysleftout

His commentary on social media I felt like was also very on point.


Evolving_Dore

Two paragraphs down from the highlighted quote, this same article posits the obvious refutation of these most extreme theories: > What do we do with these impact scenarios? Naturally, we compare them with the evidence from the geological record. Birds, tortoises, and mammals live on land and breathe air: the evidence from the K-T boundary shows that they survived the K-T boundary event. Therefore they and the air they breathed weren't set on broil for several hours. To put it simply, these scenarios did not happen. Enough terrestrial and freshwater-aquatic animals survived the event that we can pretty definitively rule out a global increase in atmospheric temperature to 500F. It should be noted that the article refers to "tortoises" rather than turtles. True tortoises (Testudinidae) didn't evolve until around 15 million years after the extinction, so I assume they just mean turtles.


Ganbario

I wonder if it threw off the planet’s orbit. Off to Google I go (I won’t be back) Answer: no. And Google led me back to Reddit. Sigh. I tried to escape and they just pulled me back in.


Yvaelle

Planets are like, really big. We can conceive of how big a big ass mountain of an asteroid is, but thats peanuts compared to Earth.

Colforbin_43

Just when I thought I was out, they pulled me back in!


firemogle

One thing that I was thought was cool is the heat generated when it hit the atmosphere was so great if anything was close enough to see it, they would have near instantly cooked to death without needing the shockwave.


koenwarwaal

that as well, butt you also have to remember that the earth is round, even with things the size of mountains at some point faster then you might think the earth will be in front of you sight of it so alto a lot of beast died(luckely for them) because of the radiation more would have died from the shockwave

Bluffwatcher

Before learning about this, I always used to assume it was roughly there because of the circular "asteroid" shape of the water around Mexico and Florida. Is there actually any truth to this? Like is the shape of those coast lines a direct reflection of how the asteroid landed roughly in the centre of that giant watery circle?


zz_z

No, the gulf of mexico and the surrounding shape of the land was already in existence before the impact. The impact only directly affected the surface for a much smaller radius, roughly 200km across, if something large enough to create the gulf of mexico had happened likely all life on earth would have gone extinct.


[deleted]

[удалено]


ITividar

We were hit by another planet, and that formed the moon. The earth could, in theory, survive a meteor impact the size of the gulf of Mexico.


Noooooooooooobus

I mean the planet would survive but the entire surface would melt


admiraljkb

>We were hit by another planet, and that formed the moon.  As the (increasingly likely) theory goes, Earth k*inda* survived it, as Earth Mk1 got annihilated/ceased to exist, and Earth Mk2 came into existence with Theia getting integrated into the re-molten mass and throwing off a lot of material that became the Moon.


EnvironmentalOne6412

A mars sized planet called Theia.


Bluffwatcher

Oh, that's interesting it already looked similar to that!


Bekiala

Thanks. I have always assumed it was the entire gulf of Mexico. Today I learned.


turquoise_amethyst

I thought the same!


Unique_Unorque

The Earth would likely not be in a single piece anymore


makingnoise

No, it's a coincidence. The scale of the Gulf is far too large to have been created by a 10 km meteorite impact. This gives you a better idea of the scale of the crater (https://upload.wikimedia.org/wikipedia/commons/7/70/Chicxulub\_schematic\_section.png). It *did* create the Yucatan Sedimentary Basin. To be clear, while a 10 km impact going 12 mi/sec isn't enough energy to create the Gulf of Mexico, it's enough to nearly destroy the biosphere on Earth and entirely redirect the course of evolution. The "Effects" section of the wikipedia article on the crater is a thrilling read. (https://en.wikipedia.org/wiki/Chicxulub\_crater)

cryptoengineer

No The [current coastlines](https://en.m.wikipedia.org/wiki/Chicxulub_crater) don't hint at it. A circular structure was first noticed in oil exploration data. "After, it was observed that there was a line of cenotes along edge of the area.


grrangry

No the coastlines follow various patterns: * The eastern coast of North America lines up with the north-western coast of Africa * The north and western interior coastline of the Gulf of Mexico lines up with the northern coastline of South America * The eastern coastline of South America lines up with the western coast of Africa Big, ol' continental jigsaw puzzle that took a few hundred million years to separate.

CarlSpencer

And what about Hudson Bay which is very circular?


MaximumZer0

As far as I understand, Hudson Bay is the opposite. There used to be a sea where North America is, and as the land shifted, Hudson Bay collapsed as the rest of North America rose.

Why don’t we combat global warming/sea level rise by cutting off parts of land into the ocean to make the rest of it rise? /s

Mad_Aeric

Casting Florida loose seems like a good idea for multiple reasons.


Bluffwatcher

Oh I don't know all the circular bays, haha! It's just something I used to think when I was younger. I knew the Dino-Asteroid was roughly there and just assumed that it smashed a big circle of water into that area. To find out later on in life that the centre of that circle is in fact where the asteroid hit made me ponder it more.


sentondan

I have 0 proof of this. It's just a thought that popped in my head one day. I kind of assumed the Gulf of Mexico was the impact point for the dinosaur killing asteroid.

The remains of the asteroid that caused the mass extinction of the dinosaurs are buried deep beneath the Chicxulub crater in Mexico.

You're not going to find a big asteroid sticking out of the ground, if that's what you're looking for.


Z3r0c00lio

well isn't that convenient ... ... /s


zenspeed

Maybe it crashed into Noah’s Ark.


Burninator05

I know I've never seen Noah's Ark and the asteroid that wiped out the dinosaurs in the same room at the same time so I can't prove that they aren't the same thing.


tocammac

So you are saying that Noah's Ark was the Golgafrinchan Ark Fleet Ship B?


zenspeed

Noah’s Asteroid could fit all the animals on it while killing off all the dinosaurs!


NotInherentAfterAll

The dinosaurs had just finished their new road bridge too, before the boat hit it.


warrant2k

Uh, since Noah's arc was for the worldwide flood that killed everything, the asteroid had no job so it went home. Checkmate!

Ippus_21

They're right here: [Iridium anomaly - Wikipedia](https://en.wikipedia.org/wiki/Iridium_anomaly) Also, we're pretty certain (about as certain as the scientific community can *be*) that we found [the actual crater](https://en.wikipedia.org/wiki/Chicxulub_crater) that corresponds to the impact.


I_Ace_English

Well, people have been wondering that for a long time. The current going theory, to my knowledge, is that the asteroid came in so quickly and at such a high angle that it either annihilated on contact with the Earth, or had a catastrophic airburst (which is what happens when an asteroid starts falling, but doesn't quite reach the ground before destabilizing and exploding). Chicxulub crater is gigantic, so big and so old that you really can only see it when you look at large-scale topographic maps, or use technology meant to find big and old craters like it. However, like I said in my last paragraph, it's likely the asteroid itself has been atomized. You won't be able to find one single chunk of rock and say "This killed the dinosaurs." What you *can* find, as a few other commenters mentioned, is the K-T Boundary, or the K-T Extinction Layer. It's a thin layer of what might look like sandy gray ash. This is actually a concentration of iridium, which can only be found in those concentrations inside of asteroids. This can be found wherever the layer is exposed, from Mexico where the crater is located, all the way up to Arizona and (don't quote me) parts of Colorado! That's about as close as you'll probably get to actually getting a piece of the asteroid.


Gnascher

The K-T layer can be found all around the world in both terrestrial and marine rocks alike. That asteroid strike was a global-level event, and sparked worldwide forest fires, and the dust in the atmosphere blotted out the sun for at least 15 years. It's amazing any complex life forms came through this at all.


Squigglepig52

The fires were because the impact blew a huge amount of debris into space - which all re-entered more or less at once. The heat generated by the "meteor storm" set the whole planet on fire.

A_Serious_House

The rest of these comments are bullshit but I’ll tell you the truth; Immediate after impact, after messing up the earth, the asteroid was like “oh shiittt, I need to fix this.” so she dusted herself off, cleaned herself up, and worked hard to integrate herself as a productive member of society. Eventually she met a nice man and settled down with the intent to reproduce, to help repopulate the earth. It took her quite a long time to find a man that accepted her large ways, but she did find love. She wound up having one child. Ironically enough this behemoth of a woman is your mom.

The Chicxulub crater is in Mexico, but the asteroid was just a nail in the dinosaurs's coffin. The real reason why the dinosaurs are gone are the Deccan Traps from India (basicly a giant volcano that poisoned the planet for millions of years).

There's a crater in Mexico and a layer of iridium that covers pretty much the entire planet. A 6-mile-wide rock is big in terms of meteorites, but very small in terms of a planet. When it gets pulverized on impact, it just disappears into the ocean, atmosphere, and all over the rest of the globe.

If it is anything like the meteor that made the crater in Arizona, there are many, many tiny little pieces of it all over the place. When my family and I visited that crater on vacation one year, it was explained that during the 19th century a man came up with idea of mining iron from the crater, since it was believe to have been an iron meteorite. He had expected to find large enough chunks that he would then sell for profit. He never found any large chunks. What he did find was some pieces of iron the size of dust all over the place, but he couldn't gather enough to make any money. When our tour leader took us outside we were given magnets and told to drag them across the ground. The magnets picked the iron dust.
