[@ToaArcan]

Fun fact: The meteor hit so quickly that it was already carving out the crater before it even hit the ground. It also punched through the atmosphere at such a rate that it left a hole in its wake, and pieces of Earth's crust would've been ejected through this vacuum into space. It's estimated that some of these pieces could've made it as far as Jupiter's orbit. Part of the reason that the meteor impact theory was so contested was that humans simply... don't like the idea that something as random and uncontrollable as a rock from space could cause the extinction of 75% of all life on the planet, because it means it could happen to them, without warning, and with no recourse.

Great chance to put computer graphics to use... make a disaster movie to shame even _2012_ , because this one actually happened. Thanks for the video, sir.

[@robbie_]

I would love it. There's a great KZbin video showing graphs and so on of the impact as it happened and for the following 8 or so hours. You know, the heat pulse, the shock wave, the tsunamis, etc. Someone should give a cgi company $500 million to do a proper movie. One that lasts eight hours. Interactive, so you can choose from a series of "cameras", etc. I would so love that.

[@deusexaethera]

Fun fact: At the speed the Chicxulub Meteor hit the Earth's atmosphere, it would've heated up enough to emit gamma rays. All life within line-of-sight of the meteor's entry plume was instantly vaporized by the heat and radiation and never even saw the impact itself. _(yes, I know heat and radiation are both electromagnetic waves, but it's still worthwhile to distinguish between high-frequency ionizing radiation that causes cancer vs. low-frequency thermal radiation that just sets things on fire.)_

I thought the impact frequency was 1? :-)

[@flamencoprof]

@@deusexaethera Let me know once you are :-)

[@deusexaethera]

@UC5ruBjcvekHkhf1l_R7ypKQ: You don't actually hate to be that guy. 😉 All hot plasmas emit ionizing radiation, all meteors generate hot plasmas during atmospheric entry, Chicxulub was unusually large and moving unusually fast, and so it generated an unusually large amount of unusually hot plasma during atmospheric entry. Keep in mind Chicxulub was so large that Earth's atmosphere would not have slowed it down significantly -- when the leading edge reached the ground, the trailing edge was still in the stratosphere -- possibly even higher, since the maximum estimated size is ~50 miles across. It had so much kinetic energy that the leading edge would've been traveling at full speed even as it pushed through the lower troposphere, and the plasma generated from that interaction would've been as hot as a thermonuclear explosion. I wouldn't be surprised if there were a small amount of actual nuclear fusion occurring in the compressed plasma between the asteroid and the ground in the instant before impact.

[@iambiggus]

Any gamma radiation being emitted by an asteroid would be immediately absorbed and scattered by the atmosphere between the ground and said asteroid.

Just a note. Dreadnoughtous, while huge, was not the largest dinosaur. The biggest known was still likely Argentinosaurus, a beast so big that very large specimens may have been 115-130 ft long and weighed around 110 tons. Recently, bones of yet another huge titanosaur have been discovered but they need to be dug up before estimates of size can be made.

[@justamicrowave2572]

I’m pretty sure the “new titanosaur” you are talking about isn’t super new, but its size can only be speculated due to the only bone that has been discovered being a single vertebrae. If it did scale up like other titanosaurs, it would easily be the heaviest dinosaur.

[@yourroyalhighness7662]

@@justamicrowave2572 I believe the discovery I am referring to happened within the past year or so. This is a newer find than Patagotitan. Argentinosaurus seems to still be one to beat so this new one (if it is indeed a new type) will have to weigh over 110 tons to exceed Argentinosaurus. Not all paleontologists agree on the upper weight limits of Argentinosaurus. I am using the upper end of the scale when I refer to it's weight range.

I just wanted to say how much I appreciate this channel, your other channels, and the information that they provide. I grew up in a fundamentalist Christian household and unfortunately my science education was absolutely abysmal. Because of channels like yours, biographics geographics mega projects and the others, I have learned so much. It is truly a wonderful experience and I cannot explain to you how grateful that I am. This video was fantastic, thank you so much!

[@sidusgekst]

Hey count me in bro! These are exactly my words. Now we're free to discover what really is going on with this planet, and IT is so much bigger than any ancient bible writer could have imagined!

[@nono-fb8tr]

[@DixtunBabyAngel]

Funny though that my one problem with the video is he mentions the Bible as if it's a good thing humanity had it. Pfft. Christianity really is the worst religion to happen to humanity. Educational videos like these need to stop perpetuating the Bible's undeserved status in our current society.

[@midgetydeath]

Then your fundamentalist parents were not fundamentalists and ignored the fact the Church considers scientific study to be a literal form of worshipping God, having a scientific branch for that very reason and creating a huge number of scientific fields of study in the first place.

I've had a few criticisms about accuracy, but I absolutely love Simon's presentation. He is extraordinarily articulate and I think he does a great job of adding just the right amount of wit to make the information more entertaining. I've seen dozens of these videos and I don't think I have yet seen him trip over his own tongue, use filler phrases or stall with "um" or "ah" (think Justin Trudeau) while he was formulating how to communicate a point. He is an absolute virtuoso of oratory and that really is exceedingly rare. Kudos to the whole team who do these videos. I absolutely love them!

@ DragonKittyCombi RE: " I'm 36 years old and still to this day I get sad when I think about the poor dinosaurs." Why? Remember that it was the extinction of the dinosaurs that allowed our mammalians ancestors to eventually evolve into human beings. If the ecology hadn't been drastically rearranged, we would still be little rat-like creatures scurrying around at night trying not to get stepped on or eaten by dinosaurs.

At 53, I can clearly remember the Geologic paradigm shift after the worldwide iridium layer was confirmed at 65My ago, later corrected to 66My ago.

[@CaliforniaBushman]

No. Multiple 1000 foot tall tsunamis have a way of evicserating everything worldwide. A 6 mile diameter meteor moving at 50+ miles per second will see a liquid or solid as equally vaporizable just like a body hitting water or land will be equally dismembered while falling from the sky. Six miles is about 32,000 ft. So as one side of the meteor hit water in the Gulf Of Mexico, the other was simultaneously at the cruising altitude of a commercial jet! Furthermore, the sedimentary layers, under the water instantly vaporized into a plasma on impact, were chock full of sulpherous rock layers - forming noxious sulpher gas. Micro dust in the stratosphere which reflects the Suns Ray's just like sulpher particles do for years after a large volcanic eruption. This has no bearing on religion. Geologic history is rife with incomprehensibly vast Catastrophic events over a 4 billion year period. But also, a uniform history of long steady erosion at the same time over billions of years. It's not either/or like Geologist used to argue. It's both.

I saw a documentary on this awhile back. Interesting stuff. One thing that stuck out to me was if you drew a line from the center of the impact crater to Phoenix, AZ and then drew a circle that everything within that circle would've been vaporized almost immediately. Pushing into Canada and South America life had about mere minutes left and life on the European, African, and Asian land masses had about 2 hours left to live.
