I'm sure I've read somewhere that if it did hit deeper water, it wouldn't be an extinction due to the lack of soot and dust that would completely over take out atmosphere. It'll be just a super tsunami and coastal areas would be catastrophically destroyed but it wouldn't wipe us out. If the Chicxulub landed a few minutes later or earlier, it would've landed in deeper water, theoretically saving the dinosaurs from extinction. Funny ol' world.
Lloyd Jones It’s a 6 mile wide meter falling at 40,000 miles per hour it would’ve certainly caused an extinction event, deep water or not. It caused mass extinction in the water and land, all of that energy has to go somewhere. There were many more catastrophes the asteroid impact did besides the soot and dust. EDIT: The asteroid hitting deeper water wouldn’t matter because it’s so hot that the bow shock would instantly turn the water into plasma and would have less than a split second of contact with the water hardly doing anything to the asteroid. So it would punch through and hit the crust anyways. It’s like expecting a cotton shirt to protect you from a bullet.
I live in Montana, and geologists at the University of Montana have found layers of sediment in rock that seem to contain ancient sea plankton and algae that could not have come from the Pacific Ocean, but would seem to be from the Gulf of Mexico or the mid-Atlantic. One thing that may not have been taken into consideration is existing rivers, deltas, lakes, and interconnected waterways throughout the North American continent; if you really wanted to, you could row a paddle boat from Montana to the Gulf with relatively little artificial interruption in the present day, via the natural rivers which all drain into the Greater Mississippi Delta. Basically, imagine a drainage ditch with some slow moving water in it, then a massive tidal wave sweeps in and pushes all available water Northward with immense force. All the water, both river and sea, would be pulled into those river channels and funneled in the direction those rivers had already carved a path. So it’s not at all unthinkable to speculate that the tidal surge pushed seawater up the Mississippi River (and its sub-rivers) all the way to the modern US/Canadian border, because that’s how far the Mississippi River goes.
The one quandary I encounter with your summis is that the tidal upheaval north into the Mississippi valley regardless how strong would eventual enter the Plantok straight up the arse
@MINIEVIL I looked this up and the consensus was that it didn’t break the crust but would have gotten very close to doing so. So what you’re seeing is probably very close to the mantle. Someone claimed that it created an 18 mile deep hole which then collapsed soon after.. I wasn’t able to find anything conclusive one way or the other so 🤷♂️
Florida didn't exist millions of years ago, Mexico didn't exist millions of years ago - none of Latin America existed millions of years ago - North America also didn't exist millions of years ago ... we know this because the timeline for our continents is documented - in hundreds of old records, written in Chinese, Japanese, Portuguese, Latin, Greek, Arabic, Hebrew, German, French, Russian, etc. - since they document the timeline for Earth's expansion, Earth's cataclysms, Earth's climate, the broken and subducted tectonic plates, the ocean trenches and archipelago islands, the eruption of Yellowstone and dozens of other supervolcanoes - all in one night - as thousands of smaller volcanoes erupted across four continents, those of us who actually want the truth - instead of idiotic theories - have compiled the hundreds of historic documents and thousands of independent sources that corroborate them. Since our ancestors tell us the timeline for the stratified layers of the Grand Canyon which were NOT created by Noah's flood - but several hundred years AFTER the great flood - since our ancestors tell us the timeline for the Siberian and Deccan Traps, the timeline for the cataclysms known as Nuuanu and Eltanin, the timeline for the Antarctic mountains, glaciers, ice shelves, volcanic eruptions, the timeline for the Mediterranean Sea, the Red Sea, the Arabian Sea, the Ross Sea and so on ... they also tell us the timeline for the boot of Italy, the timeline for the Arabian, Iberian, Yucatan and Olympic Peninsulas. Their reports are telling us that to believe theories from "scientists" that graduated with their C average from low level institutions with minimal entrance requirements, to believe theories from "scientists" whose IQ's of 85 to 115 are posted online for all the world to see, to believe theories from "scientists" whose IQ's of 115 and below are, at best, the intellectual equivalent of the smart kids in fifth and sixth grades ... in other words, believing in theories from unintelligent fake science gods is one option - the other option is to develop your own mind, do your own research, become multi-lingual, study the historic documents from all across our Earth and see that our ancestors documented the timeline for our continents, oceans, mountains, Earth's expansion, Earth's cataclysms, Earth's climate, etc. If you study the physics of colossal tsunami waves for decades, Chemistry for decades, geological formations for decades, hundreds of historic documents and thousands of other sources - like the maps of the landslide debris on the seafloor that displaced massive volumes of seawater which launched colossal tsunami waves that decimated the lands - if you correlate that destruction with reports in the old records and/or in the old literature - as I have done - the unsubstantiated theories from geologists, glaciologists, seismologists and volcanologists are promptly tossed in the rubbish - where they belong. P.S. The forces that carved out the Yucatan Peninsula are documented in historic records - it wasn't from an impact from outer space as geologists "theorize".
Even underground, the shelter would need to withstand the pressure of the water washing overhead. With a 50 meter tsunami bringing 50 meters of water, that's roughly 5 atmospheres of pressure.
You wouldn't survive it even in the shelter. The reason is that big waves will bring massive amount of debris and soil upon your entrance to the shelter, so you won't be able to open it afterwards and get some fresh air. Unless you have regenerating systems in your shelter, which is very unlikely.
Imagine Chicxulub as one large fragment of a much larger asteroid. That may explain the toxic (anything that touches the water within it dies) underwater lake in the Gulf of Mexico.
ingomar200 Thanks, now I see the other comment. I like the video overall, would consider showing it in a class. But a footnote/note would be nice just saying that the simulation uses modern geography not paleogeography -- what differences might we expect, e.g.? Ah, a good question for students!
@@jodybourgeois6332 not being flippant here but most of the students I have known-delt with if asked that question would answer "large floating dinosaur turds" but they were not the brightest candles in the box to be honest.
The thing is anything can happen at anytime. Maybe the fact is something bigger is already heading our way right now and it wont take long before we are hit.
@Shadowsky719 I do not have faith in believe in gos or gods. There is no fairytales in my life. However science have proven large asteroids can never come in contact with earth as both the earth and the astroid are negatively charged and as we know in magnetism same charges repeal eachother preventing any form of colliding. My apologises for not making it clear I do not believe in a 2000 year old myth. To make things clear I do not believe in a rock the size if a country can slam into earth with out good evidences of that taking place.
Impressive. Even as a simulation, it's kind of hard to see my home state of Mississippi being destroyed like that. Also, thumbs up if XKCD sent you here.
Yes, people this phenomena actually happen There's evidence of an Meteor hitting antarctica causing the Siberian Trap, the volcano which produced the Triassic extinction
It's great to see a RUclips video linked on ExplainXKCD that is still up. I started reading from #1 and almost all are down. But luckily in almost all cases someone archived it.
It's annoying that the simulation didn't use a model of the earth as it was back then; rather, it used a model of modern-day earth with a higher sea level. It completely ignores tectonic effects, which were substantial given that there was an ocean going straight from Texas to the North Pole.
Paleo-maps are *still* being developed based on geological data, but sure, let's *angrily demand* that RUclipsrs stay ahead of that research. AHEAD OF IT! ARGH!!!
Even if a bird saw the wave and tried to fly away as early as possible, they might have still been caught. Not to mention the impact likely unleashed way more energy than humanity has produced during its entire history. In a single strike.
Two things: First, if the meteor had hit deeper water, then the waves would have been at least a km high. Secondly, the distant tsunamis were made by other impacts from the same rubble asteroid. Look up the Silverpit, Boltysh and the Shiva Craters. The last one will made Chicxulub look like a pebble.
It would have been nice to have seen a simulation of what would have happened if it had landed in mid-Atlantic! Edward Bryant calculates in "Tsunami: The Underrated Hazard" that a Chicxulub-sized impact in 5 km of water would have produced a 4.6 km-high tsunami. That would have made a much bigger mess of the coastlines...
The simulation has to take into account that the impact itself changed the geology of the area. A 200 mile crater excavating out the ocean will cause some nasty tsunamis for sure.
if you had so many asteroid impact found on land imagine how many occured in the oceans since they dont restrict themselves only to land . That means that you had quite as much impacts in the oceans than you did on land so that would make a huge amount of tsunami so far . Thats why some scientists have concluded that life may have existed way far before the Cambrian era and that some kind of cataclysm may have destroyed all life on the planet and also plunged the planet into a snowball earth ice age just before the cambrian was born causing remains of those past lives to be clost to impossible to find
The movie Deep Impact, I believe, is based on the 1985 book Lucifer’s Hammer by Larry Niven and, Jerry Pournelle. This portrayed a mid-ocean strike in a couple miles of water. They predicted a tsunami of nearly 1000 meters. Lucifer’s Hammer tsunami was a west coast strike and crested on the California coast range, whereas Deep Impact was an east coast strike, with the tsunami cresting on the Appalachians. I didn’t realize that the depth of the water was significant. Makes perfect sense, though.
Are you able to simulate a deep water asteroid impact and resulting tsunami, say mid Atlantic or pacific impact? I would be very interested to see that simulation with a variety of asteroid sizes, say from 100m diameter asteroid as low speed to a 2-3 km diameter comet moving at high speed.
for anyone coming to this video in 2021… the reason evidence from tsunami effects were found in montana and other states far away from the impact was because at the time, a sea cut through North America. This sea, the Western Anterior Seaway, was affected by earthquake waves caused by the meteor impact, churning out waves up to 100 ft high.
"just" 20-30 meter waves. yeah it's smaller than you'd expect for such a cataclysm, but still monstrous. a lot of towns in tohoku were hit by waves that size in 2011 (others were hit by waves twice that size!). the sea swept over multistory buildings and continued to surge inland for hours. some of the footage left me speechless.
This is an older video so I'm guessing no one will see this. The simulation is interesting but did the creators take into account the massive amount of water thrust into the atmosphere and flash evaporated by the insane heat? With an impact this large, I would think these are non negligible values
“Florida did not exist” say no more my friend, winding the clocks back as we speak, sounds like a much better time in the history of our planet, meteorite and all
Ive heard geologists and paleontologists say that the wave's initial amplitude would have been around 3 miles high. 100 metres is only 1/5th the size of the Lituya Bay tsunami of 1958, which was caused by a rack much, much smaller than a 6-mile wide asteroid.
mydic k The water is not mobilized as a wave. It explodes upon decompression behind a hypervelocity shock front. Totally different physics. The sky's the limit. Well, orbit, really.
I should have also added that you aren't limited to water depth. The difference between a thin veneer of water and the bedrock below is utterly trivial at 20 km/second with a multi-km impactor. At close proximity (maybe 10 crater diameters...?) the bulk of the material making up the wave would probably have been solids moving like a fluid! :D
Based upon Continental Drift the center of this impact would have been about 185 km south of Mobile Alabama. The Crater Rim at least 3,000 meters high would stil be substantially there. Erosion and alluvial deposits would be amazing as well. This event would have produced nearly 275 meters of deposition north of Birmingham Alabama in the region (Exit 282 US I 65) where the KT Boundary 2 to 4 mm thick is exposed. No such deposit exists. This crater did not happen! The data is not there! The actual data shows 20 m of Sandstones above a layer of KT and shales below. Above the sandstones are 20 m or so of deep sea floor limestones. Above that are Coal deposits and additionally more limestones and sandstones. If you go observe this location see that you learn about the dip in the Birmingham Area so you get your observations right. (South will be to upper level deposits as you move towards Birmingham Al. ) The coal is supposed 220 Million years ago. The Limestone 660 million. or 200 million depending on the deposit. The story this tells is of a sea intrusion into the area for an extended period.
Minepose98 I am saying that what we are looking at is not an impact crater. There is no data to support the impact hypothesis. If you doubt me try going to any of the online calculators for such an impact and put in the data. Then remember that the hole created by such an impact would completely lose any of the existing sediments. That is all sediments from the mantle up would be blown away at the crater site. Only younger sediments would happen to be at the site. A classic example of evidence here is the claimed ring of pits that supposes to surround the site. These are limestone and sandstone structures much older than the proposed crater date. Limestone formations on earth are proposed to be at least 220 million years old and most are 660 or so. These would not be in the area if this "impact event" had happened. They would have been only remaining in the highly uplifted ring at the edge of the crater. The magnitude of the crater would have even with erosion largely remained though eroded intact. The fill of the crater would all date after the 65 MYO date. It wouldn't have the limestone in it. You have made a classic mistake. The "Crater" doesn't exist. The location data are available to all who are willing to look. The event didn't happen as stated. The site you are looking at is most likely a Caldera from a Krakatoa type eruption and subsequent erosion. Such events do not produce the disruption of geologic strata far from the explosion. They are for the most part fairly local in their effects and don't produce the massive crater rim that an impact would have done. I have seen the seismic maps of the area and that is what they say. I am willing to accept that there might be other explanations but the evidence for an impact is missing. Actually the extinction data doesn't fit an impactor either. It was too selective of what died. The fact that you see a well crafted story with pretty video induced hallucinations doesn't make them facts. Recently much evidence of many Dinosaurs having feathers has been found. Do you see that in the movies? Recently much data on dinosaur tissue preserved has been found. Do you see that open for discussion or the facts that this is not possible with the supposed ages? I only report to you the facts. I am not making suppositions as to the explanations but it is clear that the old ideas don't work. Recently we have gotten astronomical observation data and material samples that invalidate the Nebular hypothesis for planetary formation. Do you see that in the Movies? Recently much has come to light that invalidates the theories of star formation and physics. Do you see that in the MOVIES? Invalidation of stories and theories does NOT prove that I am right in any supposition I might have regards what happened. It only destroys the theories. Good science doesn't hold on to invalidated theories. Good science sticks to facts and tests all theories, If I propose an explanation it to is subject to test and invalidation. If my explanation is invalid it does not by logic infer that the other theory is right. Cratering science is pretty predictable and sufficiently reliable now to be passing muster for being accepted as probable facts. These calculators may have errors but their substantive "facts" are reliable. The Ejecta and form of a crater impact and the results are fairly well defined now. These results are clearly missing in the alleged crater site. Either the impact results were outside the predictable bounds (Unlikely) or it didn't happen. With the impact out of the picture we must move on to more and better theories.
Great simulation! I wonder if geologists have made any progress determining the shape of the Chicxulub crater and if would shed any light on the angle that the asteroid hit the ocean?
Curious to know what tsunamis the impact triggered. Mountains may have fallen into oceans or volcanos might have erupted underwater. A combined (stacked or amplified) wave might be the answer.
Does this simulation only account for water displacement from the impact and not the displacement caused by the shockwave in the ground? I would imagine an impact like this would cause shockwaves in the ground that would also displace water far from the impact site. In my mind if you factor in the bedrock hopping up and down for hundreds of miles around the impact the resulting tsunami should be larger than projected here.
Actually, crocodiles were not dinosaurs. Pterasarus (flying guys), snakes, turtles, and modern reptiles are not descendants of dinosaurs either. Chickens, however, are one of the decendents of the dinosaurs.
@@celestial6489 "Archosauria is the crown group containing the most recent common ancestor of crocodilians and birds and all its descendants.

"Fact is, the Chicxulub tsunami was restricted to ~100m size because the impact struck in water ~100m deep." So what you're saying is, regardless of the amount of energy released, the size of the tsunami is restricted to the depth of the water where the impact happened? Could deformation of the crust under the impact create a bigger wave?
+Kakto Tak So what you're saying is, regardless of the amount of energy released, the size of the tsunami is restricted to the depth of the water where the impact happened? Yes, pretty much. There is just not enough water to make a bigger wave. Suppose an asteroid blew out all the water in an ocean of depth H to a radius R. Now deposit that water in a tsunami ring between radius R and aR , a>1. How high would the water reach? Well the volume of water removed is Vol= pi R^2 H. The area of the ring is Area = pi R^2 (a^2-1). The height of the tsunami would be Height= Vol/Area = H/(a^2-1) If a=2 the wave height is H/3. If a=1.5 the wave height is H/1.25 If a=1.25 the wave height is H/0.56. The tsunami can't be much higher than the depth of the water H no matter the impact energy. Once all the water is blown away, most the extra energy goes into digging a deeper crater in the ocean bottom crust.
+ingomar200 I believe it will become slower and higher with distance. WHen there's not enough depth to create huge "enough" wave, the water will be just shot outwards at a much larger speed than normal speed of tsunami. You can see it in simulation - the ocean botom is bared for some time at the point of impact.
***** It would vaporise the volumes close to impact, but due to short duration of impact it would be heated up to super high temperature and expelled into sides - not much of that heat would make it into larger volumes of water. Also, water takes lots of energy to be heated up and vaporized.
Tectonic plates have been cracked in several places - by the force of colossal tsunami waves >>> shoving >>> the land - like an Earthmover - into piles of mountains. The land was shoved - in all directions by the tsunami waves. I measured the distance of three different locations, where the tsunami waves moved in three different directions - it's the same shocking distance. Bathymetric charts, dozens of old maps, reports in captains logs, evidence from scuba divers and the calculations all corroborate one another. The data strongly suggests another series of colossal tsunami waves are coming soon.
Coriolis terms are in the code but are usually turned off for being small compared to other driving forces.As they are proportional to fluid velocity, Coriolis effects might be worth a re-look as the water is ejectedvery quickly in this case.
American point of view: Several US states disappear. Mexico and Central America: and what about me, Am I a joke to you? Far South America: oh that’s a big Quake body.
Like stated before from Teddy at 1:21 the sea floor becomes visible, what this animation doesnt take into acount is how deep did the asteroid go (crater) into the earth, wich acording to Wiki the crater is 16 kilometers deep (20 miles) so the returning water to fill that giant hole must have made the tsunami several kilometers or miles high.
oh ffs if you going to use someone's else animation and try to create a video about science, plz for love of everything you hold dear, plz use accurate information, Chicxulub crater is at least 184x184km in diameter, around 12km deep and was created by an object of at least 15km in diameter, numbers vary but agreed size is around 15 to 20km. The object in question had a mass off around 9-11 trillion tons,
Your 184 km value is measured outer ring to outer ring. Perhaps you would like to learn Mic, that the pertinent parameter for impact tsunami generation is the diameter of the transient cavity or transient crater. This is much smaller. For transient crater size, the 100 km diameter quoted in the video is about right.
0, the Tsunami wasn't what killed the Dinosaurs. Even if the Dinosaurs had managed to rip that sick wave dude they would have still died of starvation like all the other dinosaurs.
Oh I know the impact effects caused the collapse of of the planet's ecosystem, but still, they probably could have survived a little longer if they had saved up some emergency supplies instead of gorging on every prey they came along. Tyranosaurus Rex looks like an efficient killer but apparently not much of a forward thinker.
Their relatively short arms would not have been much good for maintaining balance on the board, but I guess they would have used their tails for that. What a spectacle. I'd give anything to see that.
Crazy request just for fun: create a simulation of the Pangaea continent being split by multiple meteor hits (using the current trace of impacts) that would have rained on earth at the time.
Thanks AF. That's nice to see, though my point was that I would like to test the hypothesis that huge impacts with something that came from space and hit the original continent when all 5 continents were all together in one piece (not the actual split continent) could have caused the splitting of the unique continent into 5 continents. And I am talking about not one unique impact but many impacts at the same times at different location of the Pangaea continent (the original one continent). I envision a rain of objects hitting the continent, exploding and resulting in the breaking of the original continent. It would change completely the science of geology as we know it. This breaking of the continents would have occurred very fast as well as all the geological sedimentation on all continents. It would change completely the interpretation of the earth facts and the geological timeline. So for those who can do video simulation, it would be interesting to view the Pangeae continent being hit by multiple objects (using the actual visible impacts) and breaking up into 5 continents. Who can do this?
Marc Letourneau Even if many massive objects simultaneously struck what we understand to be the 'borders' between the landmasses that were once Pangaea, that wouldn't cause them to split apart. The landmasses don't just sort of float. They're anchored to extremely massive tectonic plates. No series of objects could impact those plates and cause them to change directions without completely obliterating the face of the planet in the process.
The Pangeae continent split. That is a fact. Now how to explain why the continent split may need an out of the box idea (and how this continent came about is another very difficult question). Normally, the earth should have been all covered by water and the bottom of the ocean should have been shallow and equal everywhere except where volcanoes erupts. Here is a scenario I want to test: What if, as Francis Crick and Enrico Fermi intuitively thought, the Earth was discovered by intelligent life who started terraforming the Earth. They would create a continent, maybe using explosions disposed in such angles to accumulate the bottom in one area, the Pangeae continent. Then, thousand years later, maybe because of problems, they want to redo the terraforming, they decide to destroy it by bombing it. So the impact we see on our continent would not be impacts of meteors but impact of tremendous explosion. The difference between a meteor impact and an explosion of a bomb is that the energy, rather than being mostly vertical in the case of a meteor, is spherical, pushing in all direction, capable of breaking a continent is the poser is strong enough. And the power of those bombs would be calculated to do just that, destroying all life on earth. The they would redo the terraforming avoiding the mistake they did at their first try. And now we are looking at the Earth and trying to explain it using the assumption that all that occurred naturally. That is a enormous bias if you ask me... We do this in science because scientists hate the mysticism of the creationists and they absolutely do not want to give them any support. But by avoiding any external intelligent interventions as an explanation of the earth geology, they are throwing the baby with the bath water, and if this is what happened, they will never find out and just fill out their scientific journals and a lot of bla bla. The science process is not done by the book, it is bias at the source of all interpretation of the geological facts. Now, did you notice that the Yucatan impact is on the edge of the South American continent? If yo put the continent together, I could see the explosion occurring to that location, the continent breaking up at that location and moving away (few weeks maybe) accompanied by tidal waves that covered the continents breaking up, creating mountains, volcanoes, covering entire forest that formed into oil once recovered without air, life form pressurized into fossils, beast surprised eating and carried away and frozen as is with branches passing through their bodies with leaves in it..., other beasts fighting each other and recovered in their fighting position... all this that we find on Earth, plus plenty of anomalies that we cannot explain except through a catastrophe of this kind. I just want to test it, and before you toss it with a little gesture of your hand , just think that discoveries are always the result of divergent thoughts, often contrary to the main stream. And it is always a passion to venture where no one went before, no matter the result, it is fun!
Marc Letourneau I don't want to dismiss your belief on the grounds that it requires extraterrestrial intervention, though I don't agree that we can even make that hypothesis with the complete lack of evidence that we have now. Rather, I'll challenge it in terms of the physics involved. The simplest way I can think of of refuting it is to keep in mind the existence of friction. Every moving tectonic plate is dragging across a number of other masses moving in all sorts of directions. Based on the relative displacement of North America from Africa, the coefficient of friction between a tectonic plate and the material underneath, and a few estimations about the mass of such a plate, the North American plate has lost 5.582871e+32 Joules of energy due to friction over its very long journey. If a bomb was detonated 200 million years ago (The approximate age of Pangaea) and ALL of its energy was perfectly transmitted into the motion of the continent (Which is wildly impossible for many reasons), it would be stopping now, BUT, immediately following the explosion, it would have to be moving at roughly 386 kilometers per second, But because it was moving so rapidly, friction would be acting very rapidly as well. The massive deceleration would totally obliterate the landmass and everything on it. (And on every landmass, since this bomb would have to be detonated in the center of all of them.) For this horrible catastrophe to not have happened, either these extraterrestrials have been SLOWLY imparting, still, massive amounts of energy to our continents for the past 200 million years, or there's a geological force causing the plates to remain in motion. I would argue that one of those things is a lot more likely than the other.
In the extraterrestrial scenario, every interpretation of facts would have to be revised. Instead of a slow and gradual transformation of Earth, it would have been catastrophic and quick. Radioactivity would not be natural but artificial from the time the continent was created, and from the time it was split apart. From that, radio dating would also have to be revised. Interpretation of layers of sediments would also have to be revised as they would have occurred in term of a couple of months due to tidal waves recovering the continents and rushing out creating deep canyons relatively quickly). This bombing could have occurred between 8,000 to 11,000 years ago. This actual movements of the tectonic plates would be residual from the bombing time. It is fascinating how many not very known facts (they are not very known for a reason- they are not talked about because they cannot be explained easily or not at all) would be explained by this.
I think perhaps your computer model is off just a tad bit. The resulting tsunami waves were much higher. Well over 500’ high. But this is an older simulation.
Ironically, a deep water impact may have been far less devastating to life on earth because of the much smaller size of the resulting ejecta cloud and the global heating/cooling from that ejecta cloud.
This is in response to the video regarding the Chixulub impact. Such a large and violent impact would also push the atmosphere out of the way, creating devastating wind, how far and fast would that wind destroy everything in its path?

alecbg919 I know that wave is goddamn GIGANTIC if you think about it
I'm sure I've read somewhere that if it did hit deeper water, it wouldn't be an extinction due to the lack of soot and dust that would completely over take out atmosphere. It'll be just a super tsunami and coastal areas would be catastrophically destroyed but it wouldn't wipe us out. If the Chicxulub landed a few minutes later or earlier, it would've landed in deeper water, theoretically saving the dinosaurs from extinction. Funny ol' world.
Lloyd Jones and we would may be not even excisting now🤔
Lloyd Jones It’s a 6 mile wide meter falling at 40,000 miles per hour it would’ve certainly caused an extinction event, deep water or not. It caused mass extinction in the water and land, all of that energy has to go somewhere. There were many more catastrophes the asteroid impact did besides the soot and dust.
EDIT: The asteroid hitting deeper water wouldn’t matter because it’s so hot that the bow shock would instantly turn the water into plasma and would have less than a split second of contact with the water hardly doing anything to the asteroid. So it would punch through and hit the crust anyways. It’s like expecting a cotton shirt to protect you from a bullet.
Imagine if it hit the Mariana Trench
I live in Montana, and geologists at the University of Montana have found layers of sediment in rock that seem to contain ancient sea plankton and algae that could not have come from the Pacific Ocean, but would seem to be from the Gulf of Mexico or the mid-Atlantic.
One thing that may not have been taken into consideration is existing rivers, deltas, lakes, and interconnected waterways throughout the North American continent; if you really wanted to, you could row a paddle boat from Montana to the Gulf with relatively little artificial interruption in the present day, via the natural rivers which all drain into the Greater Mississippi Delta.
Basically, imagine a drainage ditch with some slow moving water in it, then a massive tidal wave sweeps in and pushes all available water Northward with immense force. All the water, both river and sea, would be pulled into those river channels and funneled in the direction those rivers had already carved a path. So it’s not at all unthinkable to speculate that the tidal surge pushed seawater up the Mississippi River (and its sub-rivers) all the way to the modern US/Canadian border, because that’s how far the Mississippi River goes.
The one quandary I encounter with your summis is that the tidal upheaval north into the Mississippi valley regardless how strong would eventual enter the Plantok straight up the arse

Florida didn't exist millions of years ago, Mexico didn't exist millions of years ago - none of Latin America existed millions of years ago - North America also didn't exist millions of years ago ... we know this because the timeline for our continents is documented - in hundreds of old records, written in Chinese, Japanese, Portuguese, Latin, Greek, Arabic, Hebrew, German, French, Russian, etc. - since they document the timeline for Earth's expansion, Earth's cataclysms, Earth's climate, the broken and subducted tectonic plates, the ocean trenches and archipelago islands, the eruption of Yellowstone and dozens of other supervolcanoes - all in one night - as thousands of smaller volcanoes erupted across four continents, those of us who actually want the truth - instead of idiotic theories - have compiled the hundreds of historic documents and thousands of independent sources that corroborate them.
Since our ancestors tell us the timeline for the stratified layers of the Grand Canyon which were NOT created by Noah's flood - but several hundred years AFTER the great flood - since our ancestors tell us the timeline for the Siberian and Deccan Traps, the timeline for the cataclysms known as Nuuanu and Eltanin, the timeline for the Antarctic mountains, glaciers, ice shelves, volcanic eruptions, the timeline for the Mediterranean Sea, the Red Sea, the Arabian Sea, the Ross Sea and so on ... they also tell us the timeline for the boot of Italy, the timeline for the Arabian, Iberian, Yucatan and Olympic Peninsulas.
Their reports are telling us that to believe theories from "scientists" that graduated with their C average from low level institutions with minimal entrance requirements, to believe theories from "scientists" whose IQ's of 85 to 115 are posted online for all the world to see, to believe theories from "scientists" whose IQ's of 115 and below are, at best, the intellectual equivalent of the smart kids in fifth and sixth grades ... in other words, believing in theories from unintelligent fake science gods is one option - the other option is to develop your own mind, do your own research, become multi-lingual, study the historic documents from all across our Earth and see that our ancestors documented the timeline for our continents, oceans, mountains, Earth's expansion, Earth's cataclysms, Earth's climate, etc.
If you study the physics of colossal tsunami waves for decades, Chemistry for decades, geological formations for decades, hundreds of historic documents and thousands of other sources - like the maps of the landslide debris on the seafloor that displaced massive volumes of seawater which launched colossal tsunami waves that decimated the lands - if you correlate that destruction with reports in the old records and/or in the old literature - as I have done - the unsubstantiated theories from geologists, glaciologists, seismologists and volcanologists are promptly tossed in the rubbish - where they belong.
P.S. The forces that carved out the Yucatan Peninsula are documented in historic records - it wasn't from an impact from outer space as geologists "theorize".

Moral of story - your backyard bomb shelter better be waterproof!
Imagine the toxic poisoning when hundreds of nuclear reactors and thousands of nuclear waste storage tanks are decimated by tsunami waves.
Whirled Publishing
And imagine no one noticed that unpleasant idea because it was trivial in comparison to the total damage.
Even underground, the shelter would need to withstand the pressure of the water washing overhead. With a 50 meter tsunami bringing 50 meters of water, that's roughly 5 atmospheres of pressure.
You wouldn't survive it even in the shelter. The reason is that big waves will bring massive amount of debris and soil upon your entrance to the shelter, so you won't be able to open it afterwards and get some fresh air. Unless you have regenerating systems in your shelter, which is very unlikely.
And yet have recyclable oxygen somehow?

@Smooth Move what
It's annoying that the simulation didn't use a model of the earth as it was back then; rather, it used a model of modern-day earth with a higher sea level. It completely ignores tectonic effects, which were substantial given that there was an ocean going straight from Texas to the North Pole.

@@ingomar200 my question is, what program did you use to make this simulation? it's really cool either way :)
Even if a bird saw the wave and tried to fly away as early as possible, they might have still been caught.
Not to mention the impact likely unleashed way more energy than humanity has produced during its entire history. In a single strike.
Four minutes of fun and entertainment in a thorough-going science package. Nice.
Absolutely mindbending. I'm impressed.
Two things: First, if the meteor had hit deeper water, then the waves would have been at least a km high. Secondly, the distant tsunamis were made by other impacts from the same rubble asteroid. Look up the Silverpit, Boltysh and the Shiva Craters. The last one will made Chicxulub look like a pebble.

All of your simulations are excellent, but this one is particularly interesting.
I took my sat yesterday and this was mentioned in it. now it’s on my recommendation....coincidence? I think not
It would have been nice to have seen a simulation of what would have happened if it had landed in mid-Atlantic! Edward Bryant calculates in "Tsunami: The Underrated Hazard" that a Chicxulub-sized impact in 5 km of water would have produced a 4.6 km-high tsunami. That would have made a much bigger mess of the coastlines...
The simulation has to take into account that the impact itself changed the geology of the area. A 200 mile crater excavating out the ocean will cause some nasty tsunamis for sure.
This is the best water park ever
Good by hollyweird!
Excellent! This the first vid I've seen about Chicxulub that accounts for the different geography 65 Million years ago.
You believe this that’s funny cause I’d love to see proof
@@jackzappone881 So, you've never heard of continental drift before? That's not funny. That's sad.
if you had so many asteroid impact found on land imagine how many occured in the oceans since they dont restrict themselves only to land . That means that you had quite as much impacts in the oceans than you did on land so that would make a huge amount of tsunami so far . Thats why some scientists have concluded that life may have existed way far before the Cambrian era and that some kind of cataclysm may have destroyed all life on the planet and also plunged the planet into a snowball earth ice age just before the cambrian was born causing remains of those past lives to be clost to impossible to find
We probably had a lot more of asteroids impact which we can't see anymore because tectonic movements "clean" the craters

*Top 10 quotes taken before disaster*
Wow just what a great video. To the point and informative with excellent pacing. Good job
The movie Deep Impact, I believe, is based on the 1985 book Lucifer’s Hammer by Larry Niven and, Jerry Pournelle. This portrayed a mid-ocean strike in a couple miles of water. They predicted a tsunami of nearly 1000 meters. Lucifer’s Hammer tsunami was a west coast strike and crested on the California coast range, whereas Deep Impact was an east coast strike, with the tsunami cresting on the Appalachians. I didn’t realize that the depth of the water was significant. Makes perfect sense, though.
My father wrote that book. :)
@@tigerpournelle1020 that was a very good book. Thank him for me😎
Florida: I'm straight up not having a good time right now
Are you able to simulate a deep water asteroid impact and resulting tsunami, say mid Atlantic or pacific impact? I would be very interested to see that simulation with a variety of asteroid sizes, say from 100m diameter asteroid as low speed to a 2-3 km diameter comet moving at high speed.
for anyone coming to this video in 2021… the reason evidence from tsunami effects were found in montana and other states far away from the impact was because at the time, a sea cut through North America. This sea, the Western Anterior Seaway, was affected by earthquake waves caused by the meteor impact, churning out waves up to 100 ft high.
Yay I’m in Ohio and I lived!!! :D:D
Edit: Nm the wave just went up the Ohio River and deleted me from existence. I forgot they can do that. :(
Living in ky, the tsunami won't get me, but, the flooding and earthquakes...yeah...that will.
Ty’s Coins probably not the shock waves ,earthquakes ,and from the intense heat from the impact it could melt the polar ice caps leading to flooding

Came here from wonderful person, Anton Petrov's Channel. Very interesting video. I'll have to check out more of them. Thanks
This is an older video so I'm guessing no one will see this. The simulation is interesting but did the creators take into account the massive amount of water thrust into the atmosphere and flash evaporated by the insane heat? With an impact this large, I would think these are non negligible values
i like these videos but you really should have recorded words or music

What if that hit the Pacific ocean?? I heard that it would something like 15,000, ft
Ive heard geologists and paleontologists say that the wave's initial amplitude would have been around 3 miles high. 100 metres is only 1/5th the size of the Lituya Bay tsunami of 1958, which was caused by a rack much, much smaller than a 6-mile wide asteroid.
+Ricky Spanish Lituya Bay was a slosh in a confined fjord walled by mountains. It was not an open-water wave.
Is it possible that the tsunami was really 3.1 miles high?
mydic k thank you so much
mydic k The water is not mobilized as a wave. It explodes upon decompression behind a hypervelocity shock front. Totally different physics. The sky's the limit. Well, orbit, really.
I should have also added that you aren't limited to water depth. The difference between a thin veneer of water and the bedrock below is utterly trivial at 20 km/second with a multi-km impactor. At close proximity (maybe 10 crater diameters...?) the bulk of the material making up the wave would probably have been solids moving like a fluid! :D
Please tell me what program you use to do the tsunami simulations

Surely the Earths geography was quite different 65 million years ago? Continents in different places?
That was shown in the video. The continents were almost where they are today. The shoreline was different, though, as shown in the video.
Based upon Continental Drift the center of this impact would have been about 185 km south of Mobile Alabama. The Crater Rim at least 3,000 meters high would stil be substantially there. Erosion and alluvial deposits would be amazing as well. This event would have produced nearly 275 meters of deposition north of Birmingham Alabama in the region (Exit 282 US I 65) where the KT Boundary 2 to 4 mm thick is exposed. No such deposit exists. This crater did not happen! The data is not there! The actual data shows 20 m of Sandstones above a layer of KT and shales below. Above the sandstones are 20 m or so of deep sea floor limestones. Above that are Coal deposits and additionally more limestones and sandstones. If you go observe this location see that you learn about the dip in the Birmingham Area so you get your observations right. (South will be to upper level deposits as you move towards Birmingham Al. ) The coal is supposed 220 Million years ago. The Limestone 660 million. or 200 million depending on the deposit. The story this tells is of a sea intrusion into the area for an extended period.
I can't really understand you. Are you saying the KT impact didn't occur? Because the crater and location are known.
Minepose98 I am saying that what we are looking at is not an impact crater. There is no data to support the impact hypothesis. If you doubt me try going to any of the online calculators for such an impact and put in the data. Then remember that the hole created by such an impact would completely lose any of the existing sediments. That is all sediments from the mantle up would be blown away at the crater site. Only younger sediments would happen to be at the site. A classic example of evidence here is the claimed ring of pits that supposes to surround the site. These are limestone and sandstone structures much older than the proposed crater date. Limestone formations on earth are proposed to be at least 220 million years old and most are 660 or so. These would not be in the area if this "impact event" had happened. They would have been only remaining in the highly uplifted ring at the edge of the crater. The magnitude of the crater would have even with erosion largely remained though eroded intact. The fill of the crater would all date after the 65 MYO date. It wouldn't have the limestone in it. You have made a classic mistake. The "Crater" doesn't exist. The location data are available to all who are willing to look. The event didn't happen as stated. The site you are looking at is most likely a Caldera from a Krakatoa type eruption and subsequent erosion. Such events do not produce the disruption of geologic strata far from the explosion. They are for the most part fairly local in their effects and don't produce the massive crater rim that an impact would have done. I have seen the seismic maps of the area and that is what they say. I am willing to accept that there might be other explanations but the evidence for an impact is missing. Actually the extinction data doesn't fit an impactor either. It was too selective of what died. The fact that you see a well crafted story with pretty video induced hallucinations doesn't make them facts.
Recently much evidence of many Dinosaurs having feathers has been found. Do you see that in the movies? Recently much data on dinosaur tissue preserved has been found. Do you see that open for discussion or the facts that this is not possible with the supposed ages? I only report to you the facts. I am not making suppositions as to the explanations but it is clear that the old ideas don't work. Recently we have gotten astronomical observation data and material samples that invalidate the Nebular hypothesis for planetary formation. Do you see that in the Movies? Recently much has come to light that invalidates the theories of star formation and physics. Do you see that in the MOVIES? Invalidation of stories and theories does NOT prove that I am right in any supposition I might have regards what happened. It only destroys the theories. Good science doesn't hold on to invalidated theories. Good science sticks to facts and tests all theories, If I propose an explanation it to is subject to test and invalidation. If my explanation is invalid it does not by logic infer that the other theory is right.
Cratering science is pretty predictable and sufficiently reliable now to be passing muster for being accepted as probable facts. These calculators may have errors but their substantive "facts" are reliable. The Ejecta and form of a crater impact and the results are fairly well defined now. These results are clearly missing in the alleged crater site. Either the impact results were outside the predictable bounds (Unlikely) or it didn't happen. With the impact out of the picture we must move on to more and better theories.
The guy is a crank, don't bother.
So, the kilometer-high tsunamis we see in the movies are a lie?
Great simulation! I wonder if geologists have made any progress determining the shape of the Chicxulub crater and if would shed any light on the angle that the asteroid hit the ocean?
The most peneterating earth weapon ive never seen
florida did not exist?
we need to go back
What software do you use? i would really want a copy if its free or heck even paid i would still get it to simulate these tsunamis
Curious to know what tsunamis the impact triggered. Mountains may have fallen into oceans or volcanos might have erupted underwater. A combined (stacked or amplified) wave might be the
answer.
No mountains fell into oceans.
You have the simulation of the tsunami caused by the asteroid 1950 DA in the Atlantic Ocean in 2880, with the waves height in meters?
Does this simulation only account for water displacement from the impact and not the displacement caused by the shockwave in the ground? I would imagine an impact like this would cause shockwaves in the ground that would also displace water far from the impact site. In my mind if you factor in the bedrock hopping up and down for hundreds of miles around the impact the resulting tsunami should be larger than projected here.
Does the tsunami wave go as far inland as austin Tx?

"Fact is, the Chicxulub tsunami was restricted to ~100m size because the impact struck in water ~100m deep."
So what you're saying is, regardless of the amount of energy released, the size of the tsunami is restricted to the depth of the water where the impact happened? Could deformation of the crust under the impact create a bigger wave?
+Kakto Tak
So what you're saying is, regardless of the amount of energy released,
the size of the tsunami is restricted to the depth of the water where
the impact happened?
Yes, pretty much. There is just not enough water to make a bigger wave.
Suppose an asteroid blew out all the water in an ocean of depth H to a radius R.
Now deposit that water in a tsunami ring between radius R and aR , a>1.
How high would the water reach?
Well the volume of water removed is Vol= pi R^2 H.
The area of the ring is Area = pi R^2 (a^2-1).
The height of the tsunami would be Height= Vol/Area = H/(a^2-1)
If a=2 the wave height is H/3. If a=1.5 the wave height is H/1.25
If a=1.25 the wave height is H/0.56.
The tsunami can't be much higher than the depth of the water H no matter the impact energy.
Once all the water is blown away,
most the extra energy goes into digging a deeper crater in the ocean bottom crust.
+ingomar200 I believe it will become slower and higher with distance. WHen there's not enough depth to create huge "enough" wave, the water will be just shot outwards at a much larger speed than normal speed of tsunami. You can see it in simulation - the ocean botom is bared for some time at the point of impact.
+ingomar200 Wouldn't the kinetic energy vaporize most of the water near the impact?
*****
It would vaporise the volumes close to impact, but due to short duration of impact it would be heated up to super high temperature and expelled into sides - not much of that heat would make it into larger volumes of water. Also, water takes lots of energy to be heated up and vaporized.
Tectonic plates have been cracked in several places - by the force of colossal tsunami waves >>> shoving >>> the land - like an Earthmover - into piles of mountains.
The land was shoved - in all directions by the tsunami waves.
I measured the distance of three different locations, where the tsunami waves moved in three different directions - it's the same shocking distance.
Bathymetric charts, dozens of old maps, reports in captains logs, evidence from scuba divers and the calculations all corroborate one another.
The data strongly suggests another series of colossal tsunami waves are coming soon.
cool video, could use some audio
Does the computer model take into consideration the Coriolis force?
Coriolis terms are in the code but are usually turned off for being small compared to other driving forces.As they are proportional to fluid velocity, Coriolis effects might be worth a re-look as the water is ejectedvery quickly in this case.

Like stated before from Teddy at 1:21 the sea floor becomes visible, what this animation doesnt take into acount is how deep did the asteroid go (crater) into the earth, wich acording to Wiki the crater is 16 kilometers deep (20 miles) so the returning water to fill that giant hole must have made the tsunami several kilometers or miles high.
oh ffs if you going to use someone's else animation and try to create a video about science, plz for love of everything you hold dear, plz use accurate information,
Chicxulub crater is at least 184x184km in diameter, around 12km deep and was created by an object of at least 15km in diameter, numbers vary but agreed size is around 15 to 20km. The object in question had a mass off around 9-11 trillion tons,
Your 184 km value is measured outer ring to outer ring.
Perhaps you would like to learn Mic, that the pertinent parameter
for impact tsunami generation is the diameter of the transient cavity
or transient crater. This is much smaller.
For transient crater size, the 100 km diameter quoted in the video is about right.
Can we recreate this with other coastal modelling applications like Delft3d ?
Ingomar, you said Chicxulub was restricted to 100 meters high, but I saw one with 200 meters high, so I am afraid you are mistaken

Its only natural to wonder how many dinosaurs would have survived the tsunami if even a rudimentary surfboard had been developed in that age.
0, the Tsunami wasn't what killed the Dinosaurs.
Even if the Dinosaurs had managed to rip that sick wave dude they would have still died of starvation like all the other dinosaurs.
Oh I know the impact effects caused the collapse of of the planet's ecosystem, but still, they probably could have survived a little longer if they had saved up some emergency supplies instead of gorging on every prey they came along. Tyranosaurus Rex looks like an efficient killer but apparently not much of a forward thinker.

Crazy request just for fun: create a simulation of the Pangaea continent being split by multiple meteor hits (using the current trace of impacts) that would have rained on earth at the time.
Thanks AF. That's nice to see, though my point was that I would like to test the hypothesis that huge impacts with something that came from space and hit the original continent when all 5 continents were all together in one piece (not the actual split continent) could have caused the splitting of the unique continent into 5 continents. And I am talking about not one unique impact but many impacts at the same times at different location of the Pangaea continent (the original one continent). I envision a rain of objects hitting the continent, exploding and resulting in the breaking of the original continent. It would change completely the science of geology as we know it. This breaking of the continents would have occurred very fast as well as all the geological sedimentation on all continents. It would change completely the interpretation of the earth facts and the geological timeline. So for those who can do video simulation, it would be interesting to view the Pangeae continent being hit by multiple objects (using the actual visible impacts) and breaking up into 5 continents. Who can do this?
Marc Letourneau Even if many massive objects simultaneously struck what we understand to be the 'borders' between the landmasses that were once Pangaea, that wouldn't cause them to split apart. The landmasses don't just sort of float. They're anchored to extremely massive tectonic plates. No series of objects could impact those plates and cause them to change directions without completely obliterating the face of the planet in the process.
The Pangeae continent split. That is a fact. Now how to explain why the continent split may need an out of the box idea (and how this continent came about is another very difficult question). Normally, the earth should have been all covered by water and the bottom of the ocean should have been shallow and equal everywhere except where volcanoes erupts. Here is a scenario I want to test: What if, as Francis Crick and Enrico Fermi intuitively thought, the Earth was discovered by intelligent life who started terraforming the Earth. They would create a continent, maybe using explosions disposed in such angles to accumulate the bottom in one area, the Pangeae continent. Then, thousand years later, maybe because of problems, they want to redo the terraforming, they decide to destroy it by bombing it. So the impact we see on our continent would not be impacts of meteors but impact of tremendous explosion. The difference between a meteor impact and an explosion of a bomb is that the energy, rather than being mostly vertical in the case of a meteor, is spherical, pushing in all direction, capable of breaking a continent is the poser is strong enough. And the power of those bombs would be calculated to do just that, destroying all life on earth. The they would redo the terraforming avoiding the mistake they did at their first try. And now we are looking at the Earth and trying to explain it using the assumption that all that occurred naturally. That is a enormous bias if you ask me... We do this in science because scientists hate the mysticism of the creationists and they absolutely do not want to give them any support. But by avoiding any external intelligent interventions as an explanation of the earth geology, they are throwing the baby with the bath water, and if this is what happened, they will never find out and just fill out their scientific journals and a lot of bla bla. The science process is not done by the book, it is bias at the source of all interpretation of the geological facts. Now, did you notice that the Yucatan impact is on the edge of the South American continent? If yo put the continent together, I could see the explosion occurring to that location, the continent breaking up at that location and moving away (few weeks maybe) accompanied by tidal waves that covered the continents breaking up, creating mountains, volcanoes, covering entire forest that formed into oil once recovered without air, life form pressurized into fossils, beast surprised eating and carried away and frozen as is with branches passing through their bodies with leaves in it..., other beasts fighting each other and recovered in their fighting position... all this that we find on Earth, plus plenty of anomalies that we cannot explain except through a catastrophe of this kind. I just want to test it, and before you toss it with a little gesture of your hand , just think that discoveries are always the result of divergent thoughts, often contrary to the main stream. And it is always a passion to venture where no one went before, no matter the result, it is fun!
Marc Letourneau I don't want to dismiss your belief on the grounds that it requires extraterrestrial intervention, though I don't agree that we can even make that hypothesis with the complete lack of evidence that we have now. Rather, I'll challenge it in terms of the physics involved. The simplest way I can think of of refuting it is to keep in mind the existence of friction. Every moving tectonic plate is dragging across a number of other masses moving in all sorts of directions. Based on the relative displacement of North America from Africa, the coefficient of friction between a tectonic plate and the material underneath, and a few estimations about the mass of such a plate, the North American plate has lost 5.582871e+32 Joules of energy due to friction over its very long journey. If a bomb was detonated 200 million years ago (The approximate age of Pangaea) and ALL of its energy was perfectly transmitted into the motion of the continent (Which is wildly impossible for many reasons), it would be stopping now, BUT, immediately following the explosion, it would have to be moving at roughly 386 kilometers per second, But because it was moving so rapidly, friction would be acting very rapidly as well. The massive deceleration would totally obliterate the landmass and everything on it. (And on every landmass, since this bomb would have to be detonated in the center of all of them.)
For this horrible catastrophe to not have happened, either these extraterrestrials have been SLOWLY imparting, still, massive amounts of energy to our continents for the past 200 million years, or there's a geological force causing the plates to remain in motion. I would argue that one of those things is a lot more likely than the other.
In the extraterrestrial scenario, every interpretation of facts would have to be revised. Instead of a slow and gradual transformation of Earth, it would have been catastrophic and quick. Radioactivity would not be natural but artificial from the time the continent was created, and from the time it was split apart. From that, radio dating would also have to be revised. Interpretation of layers of sediments would also have to be revised as they would have occurred in term of a couple of months due to tidal waves recovering the continents and rushing out creating deep canyons relatively quickly). This bombing could have occurred between 8,000 to 11,000 years ago. This actual movements of the tectonic plates would be residual from the bombing time. It is fascinating how many not very known facts (they are not very known for a reason- they are not talked about because they cannot be explained easily or not at all) would be explained by this.
What computer program is this?
*"65 million years ago, florida did no exist"*
Florida man: am i a joke to you ?
The Dinosaurs: why do I hear boss music?
When it happens again I just hope it lands in Los Angeles.
Riddick tonn Typical mass murder fantasy.
I think perhaps your computer model is off just a tad bit. The resulting tsunami waves were much higher. Well over 500’ high. But this is an older simulation.
Why am I being recommenced this now
“Florida did not exist”
And thats bad how?
Ironically, a deep water impact may have been far less devastating to life on earth because of the much smaller size of the resulting ejecta cloud and the global heating/cooling from that ejecta cloud.
Oh yeah yeah
What about the shifting of the continents? Wouldn't the continents look different due to the tectonic plates moving?
This is in response to the video regarding the Chixulub impact. Such a large and violent impact would also push the atmosphere out of the way, creating devastating wind, how far and fast would that wind destroy everything in its path?
