Detailed 30 FPS simulation of Chicxulub (~200 km in diameter) simulation that likely wiped off 75 percent of Earth's species 66 million years ago. For reference, Mt. Everest is 8.8 km in elevation.
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
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.
@@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.
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.
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.
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.
@@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.
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
@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
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.
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.
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.
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
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.
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.
@@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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-AXiecm1j-2s.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.
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
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.
