Crazy to think that, for a period of time, this impact crater was both the highest and the deepest points of earth *simultaneously*
Deeper than the Marianas trench and higher than Mount Everest
Uh physics.. yeah man!
and 35 years ago no one knew about it.... I remember telling our South African leading scientists about it for the first time... at a formal dinner function...It was a show stopper
It goes about 40 kilometers deep at some moment in this animation, that's pretty much throughout the crust of the Earth. I think that black line in the animation marks the mantle? We see even that wave up and down here, even though it doesn't break like the crust.
And the ejector when more than 4 times the height airlines fly at.
FAKE. There is not a meteorite in the crater.
The flood is the cause (Gen 7: 11).
An explosion so hard it made the ground behave like jello, Not even all the nukes put together would come close
They definitely would
@@irrelevant9023 They definitely would not. The kinetic energy of a 6-mile-wide asteroid moving at the 20 km/s (the Chicxulub asteroid) is estimated at around 4x10^23 joules. For context that's around 100 teratons of tnt equivalent, or 100 million megatons of tnt. The total yield of all our nuclear weapons is a few thousand megatons at most. Not even close. The asteroid impact would have released 10s of thousands of times more energy than our entire nuclear arsenal.
Well not “all nukes” more of all URANIUM in the world turned into nukes
@@irrelevant9023 “4.5 billion times the explosive power of the Hiroshima atomic bomb.”
@@irrelevant9023you're indeed irrelevant
It's crazy that just the rebound of the Earth coming back up to ground level covered about 50 km vertically in about 140 seconds, which is pretty much the speed of sound.
It would’ve been noticeable that’s for sure
WOWWWWW !!!! Isn’t that incredible !!!!! !!!!! Wow !!!!
I'm cringing at the thought of millions of krakatoas
Cool simulation, but can we all appreciate the fighter jet that formed at 0:50?
Nice little MiG-21
migger 21
That was Terry the triceratops trying to get out of Dodge
I know what u wanted to say 😂@@belgianfried
@@MetroCop2077a bigger mig? Migger?
Great job on this amazing simulation, Brayden! If you don't mind a suggestion, I think it would give us an even more realistic idea of how the event happened if you slowed down this animation to real time, but then to keep the sense of just how huge and insanely powerful this blast was, place recognizable large buildings and monuments sized to scale on the ground to the side of the impact site, maybe starting around the 25km mark, then perhaps show them get blasted away along with the ground underneath them. If it would be too much work to try to accurately show them get blasted away, you could sinply keep them statically in place as silhouettes to remind people where the ground once stood.
A slight correction, the Chicxulub Impactor didn't strike directly down but sideways.
good point! imagine looking at it in front view.
shouldn't make a difference to the impact crater
This man was there obviously
Impact angles don't matter for crater formation.
@@k.o.hakala2112 It's true that down until rather shallow angles, the crater will be roughly circular, whatever the impact angle. However, there will still be some asymmetry in the ejecta and also in the rebound.
I bet the dinosaurs loved the music as they were dying
And to think that on a cosmic scale, it is simply two rocks bumping into each other
At the cosmic scale this would literally be nothing. We have solar flares that are a million times more massive than this impact. The scale of cosmos is truly unimaginable.
The shocking part is that the actual scale more like a salt grain bumping into a soccer ball.... And this is what a salt grain 10-15 km wide travelling at 20-22 kilometers per second can do to an earth sized soccerball.... if this impact were to be seen from the moon back then, it would be barely noticeable from there if not for the massive explosion
@@rexg1632,
The massive explosion, the steam condensing into clouds thousands of kilometers across...
@aralornwolf3140 smoke fires steam clouds... I meant that all included with "explosion"... but it won't be appearing as instantaneous from the moon it is a fast spread but from there u would notice the earth change face only after an hour or so I when i said it would be barely moticeable I meant it won't be like in the movies and all u know what I mean....
This gigantic explosive impact is a salt grain on a beachball as visible from space...
10km asteroid vs 12800 km earth
@@rexg1632 the ejecta?
So what I’m getting here is that with the proper amount of energy, anything will act like a liquid….
Or gas
Just look at planetary collision
The fact it looks like a skull at some points is absolutely poetic
You're my favorite content crater
The simulation starts with an impacting body that is 20 km. in diameter. What's with that!
Hi. The diameter of the crater relative to that of the meteorite for most craters is about 1 to 10. Chicxulub is thought to be between 10 to 80 km in diameter.
It looks like the Earth was bleeding.
Great simulation, where did you get the data for this? Is this published somewhere do just a fun this you did? I wanna learn how it was done!
Woah it formed a figher jet at 0:50
the plane has ascended from hell and descending to hell
amazing music to go with it
Was from Oppenheimer I think
Chicxulub is my favourite Pokemon.
Viridis, my favourite colormap 👍
0:05 it fits perfectly with the crust erupting out of the hollowed out ground
Would the left and rightmost areas (around -75 km and 75 km in this simulation) be where all the 'cenotes' are? Really cool simulation!
Please call them by their name: Big Breasts.
Must have been an incredible sight for that Dinosaur that saw it.
All who "saw" it were blinded when the asteroid entered the atmosphere a few seconds before impact. Post-impact, above the crater, there was a giant fireball brighter than the Sun, incinerating all those already blind dinosaurs, before the ejected rocks fell on their ashes.
What program did you use to create this?
Or rather crate this?
What software is this
What software is this? Did you write this yourself?
Mass Extinction Sim 4000
The Dinosaurs had it coming.
That absolute fountain of orbital-speed ejected debris... l
Did it impact at a perfect 90° angle to the surface of the earth? Because that's what this simulation shows.
the Chicxulub was not hit at a vertical angle. however, slant hit requires a 3d modeling, and this was a 2d model.
the movement of the small fragments seems off, why do they get pulled towards the centre?
Because the asteroid was moving at such high speeds when it hit the earth it created high pressures in it's center after the impact creating a vortex
Cool! but what's up with all those bits spontaneously flying all over the place? They seem like artifacts of the simulation.
Ejecta
maybe it's running a much higher number of particles, and the visual stuff is forming based on the density of particles. In that case you could have "waves" moving in weird ways, manifesting as visual blobs.
What effect did this have on the earth's orbit, or the length of a day?
Wait, this probably would require precise information about the angle of impact to calculate, and I doubt that can be reconstructed from the evidence available.
@@hemoglobin3751 that is actually a really good question! I think the Earth has a big enough mass to not change its orbit or length of day significantly.
probably a few seconds + couple thousand kilometers
The earth's rotational energy is almost a million times more than the energy of the asteroid. And most of the kinetic energy went into heat and the crater formation and the ejecta because the impacting body is not really that solid - it's a rubble pile kind of thing. So the earth's rotation would have hardly felt a blip.
Negligible, but It might have affected atleast a few picoseconds - milliseconds if the earth shook for months with that 13.0 magnitude quake... i think it's not just the impact doing it here but the mantle shaking and tossing around inside for months
Спасибо. Короче, ближе чем со 100 км на такое зрелище лучше не смотреть!
Maybe I am a lunatic but I would really like to see it from the earth orbit.
We know there are rings. Where are the rings? They seem to have disappeared in this illustration.
hi, great question. this is a hydrocode, which simulates asteroid. this means the end result "landscape" of the crater will flatten out significantly, unlike a real crater. the purpose of the modeling is really to see the impact part, and with time > n, it won't look realistic.
They form after about 0:50
My boi Aluxe 💀
A real inconsistency
It jumps from 60.8 to 62.8 seconds?
yeah, that's how time works
cool. but why doesn't it look like a crater at the end?
It does. Look at craters on the moon. They look just like this.
Yes it does. It doesn't look like what you wrongly think craters look like.
It does.
How to save computation time?
Do a half and mirror it 😂

I like at 0:33 when it became a giant evil cat.
It looks like liquid! :o
You know what, I feel kind of bad for the dinosaurs. Sure, they preyed on a lot of animals, but nobody deserves to have an asteroid hit their planet
That is scary🙏🙏👍👍🇬🇧🇬🇧
**actual footage**
It was 40km deep?
Transient depth
It drilled down 40 km, like a lead fishing weight hurled into a quiet pond.
Is 65 million years ago 0:00.02 seconds
DO YOU HAVE A BRAIN THE SIZE OF A PEANUT? IT OCCURRED 66 MILLION YEARS AGO!
The moon must have been littered with debris from this impact. Perhaps one day we will be able to find some of these.
очень похоже на образование кумулятивной струи
powder toys!
But..how high was mushroom cloud from this impact?
There was none -- couldn't be. The force of the impact blew a significant chuck of the Earth's crust into orbit. There's no air in space... so, no convection that creates mushroom clouds.
If anything, it was a fountain of magma splashing into low earth orbit and raining hellfire upon most of the planet for weeks.. maybe longer. That's why there are deposits of Iridium scattered across the globe carried by the asteroid itself and splashing it around the World on impact.
I don’t think there was it’s not the same as a nuke
@@theonlycube8538 why lol? The explosion working the same, it's only millions time more powerful than nuke
@@TD_JR but why no one visualizating the explosion itself? How it looked like?
@@mr_1970_lake I already explained why there would be no mushroom cloud. Mushroom clouds are created in an atmosphere where convection within the air column creates the mushroom effect. This impact was so much larger than anything man-made - it was the equivalent of 100 million megatons..... the largest bomb ever created by man was the Tsar Bomba... and that was 50 megatons. The Tsar Bomba is a firecracker compared to this.
If yuo're looking for a comparitive study -- this video is closest to what happened: th-cam.com/video/AXiecm1j-2s/w-d-xo.html
Something is wrong with the scale of this animation. If the size of the object was 200km, it would fill the entire screen based on the horizontal scale.
From 0:50 you can see Jesus descending down to save the dinosaurs
The simulation is fine but we must keep in mind that in real life it would be impossible for an impact from an asteroid to result in a symmetrical expansion of the crater since this can vary depending on the shape of the asteroid, the relief of the ground where it impacts and the inclination of the asteroid's trajectory.
Simulation rating: 3/10
shape of the asteroid does not matter for hypervelocity impact. if you want such requirements, maybe youtube isn't the best place to rate things. www.nature.com/articles/s41467-020-15269-x
That requires a 3D animation, this is 2d.
Fiction
COMSOL Multiphysics?
What’s really funny is that there is literally no evidence for any of this.
There's literally a giant crater in the gulf of mexico
You believe a lie. They excitedly talk about the crater buried under the Yucatán peninsula that simply isn’t there, and you believe it.@@rizizum
lmao bro's a denialist, the only thing about dinosaurs that could be inaccurate are how we depict them. Do research instead of listening to yourself that you're always right, and stop believing that everything in space that isn't man-made a sign of aliens. you troll conspiracy theorist.
@@garyfliess4375 nah bruv i can't take you seriously man you gotta be trolling
