Something that has never been mentioned before is that history lovers like myself, who have watched many documentaries which have featured Tony Robinson as host, and have learned to appreciate this man long after his days with ‘Black Adder’. And now this history lover is currently pursuing interests in space, science, physics, etc.. So watch out… because I’m about to bring you under the microscope. Just like Tony Robinson will. So please don’t act like this is some cute novelty, because it isn’t. Historians will bring all science to it’s knees. Tony will force the questions which will either hold up your theories, or reduce them to fallacies. Do not take Tony lightly, for he comes for the truth. Any thin scientific theory will be quickly torn asunder by Tony Robinson, so give him more respect please and thank you. He is far greater than simply the man who played Baldric in Black Adder.

The asteroid impact theory for the K/T boundary is also know as the Alvarez Hipothesis because Alvarez was the first to come up with the theory based in the iridium and shocked quartz evidences and not the scientists presented here.

This was complete BS, you are correct about Alvarez finding the Iridium in the KT boundary in Italy back in the late 70s, and Glenn Penfield with the oil company finding the magnetic anomaly, and Hildebran finding the correct spot where the astroid hit, none of these scientists in this fake episode had anything to do with it.

[@politicallycorrectredskin796]

I still don't understand how that proves that an impact caused the mass extinction, though. The Deccan Traps were open around this time. All the other mass extinctions were caused by flood basalt. So when we know such a venting event was open during a mass extinction, it is definitely a bit weird that people look anywhere else. There even seems to be a 1:1 correlation between the vent size and duration and the amount of species killed off. Except in this one case where an asteroid killed everything somehow. I just don't buy it. There is no mechanism I know of that really explains why species halfway around the world would have died because of this. But they did. All the non-avians disappeared. A short period of cold does not explain that for me. Life is rugged and very, very adaptable. You need more than a bit of cold. Most animal skin cells are very responsive to change as well. Scales are modified hair and will change quickly to insulate animals. Some of them somewhere would have survived if this was all because of a single asteroid.

[@cdorman11]

@@politicallycorrectredskin796 Yeah, my impression is that life was under tremendous pressure because of the volcanism and the asteroid finished 'em off. The volcanism was enough to wipe out plenty of land species but doesn't explain centuries of ocean acidification. The asteroid does.

Very disappointed that you left out many important names from these events: 1978: Glen Penfield, the Pemex engineer, who found the first evidence (rings) of this crater formation. 1980: Walter and Luis Alvarez, who posited the KT impact as the extinction event. 1981: Alan Hildebrand, who posited the Caribbean area as the impact site. 1990: Hildebrand and Penfield found shocked quartz samples in Pemex drill samples. It didn't take some brainy chick in 1996 to put this all together. Ocampo and her team just confirmed what was already known. She says so herself her findings were the LAST piece of the puzzle. It would have been nice to recognize those who put together almost all of the puzzle before her.

James Meyers We will eventually, no matter how hard we try to prevent it. That's just how it works.

We try to extend our lives while we destroy others and just about everything around us. That evolutionary math just doesn't compute.

[@jaredphillips129]

Alex Lubbers I believe that’s the current theory. The asteroid impact was a catalyst, and it wiped out what was within the immediate area of effect, but the subsequent eruptions from multiple super volcanoes was what sealed the fate of most of the dinosaurs. The survivors evolved into the birds that we have today.

Does anyone other than me appreciate how resilient and special our little planet really is, yes I'm sure most of you do, the fact that the Earth can rebound from such punishment is truly awesome. Would such an impact as described here have some affect on the Earth's rotation and orbit? P.S. I wonder when the next impact will be, best to live life to the fullest while we can I think.

[@WHEREISTHEREASON]

+Dan NZ Hello, Dan, I have often pondered that same question. I postulate ; The earth is rotating on an axis which is roughly 22 degrees off perpendicular from the plane of its orbit. It also wobbles taking roughly 26,000 years to complete one "wob". I believe this is the result of just such an impact. I have seen no correlating evidence of this but I am not the type to look. I have carried this to its logical (or so it seems to me) next step. Suppose humans were to correct this orbital anomaly? What if we employed hyper orbital tethered satellites H.O.T.S. at each of the poles. These H.O.T.S. would be semi satellite- sized hollow orbs into which we could pump (or suck, space is a vacuum) sand from the Sahara and muck from the Marianas trench. One tethered to the north pole and one at the south far enough out to gently tug the rotating axis back in line and then with just the right amount of spin (like the "English" on a pool ball) the tethered satellites were release at just the right moment to cause the planet to rotate on an ever shifting axis. The goals being; 1. Eliminate the extremes of sever summer and winter in favor of perpetual spring World wide, So that all areas of the surface got just enough sun light to be temperate. 2. Thaw out the poles and diverting that fresh water to the now excavated Sahara desert creating a huge fresh water lake from which to irrigate the entire area for farming, 3. Thaw out Antarctica and use it for all the deviants, miscreants and malcontents to live on ( with the money we would save on heating bills we could build a dome over Arizona and refrigerate it for the polar bears and seals) What we need ;1. A suction system to load the H.O.T.S. with maybe a space vacuum, 2. A one world government. Seriously, this is all tongue and cheek, Just something to mention at parties when everyone feels giddy( drunk, stoned, hallucinating, whatever). I realize it could never really happen. For one thing North Korea would never agree. Cheers.

No one ever shows exactly how it was because a meteor traveling that fast would hit the ground almost immediately. It wouldn't make a majestic terrifying vision blazing across the sky, it would just scream into existence out of nowhere and impact in 3 seconds.

[@DouggieDinosaur]

38:57 "The impact released billions of tons of greenhouse gas - the equivalent of *3,000 years of modern fossil fuel burning."* This raised global temperatures and didn't return "to normal values for *several centuries* after the impact." Only several centuries? Ray Kurzweil estimates solar power will provide 100% of our energy needs in 5 years (Ray is rarely wrong). I'm no longer worried about our carbon footprint.

Love this documentary another great documentary is catastrophe life on earth after an asteroid collision, same scenario as the dinosaurs but happenes to us

[@jamesstreet856]

It's a true story. It just hasn't happened yet. There's one out there right now that's coming straight for us. Maybe it's still in the asteroid belt. But it's coming. We just don't know how long it will take to get here.

[@accessaryman]

here's some food for thought, if the asteroid was as large as stated at 22:18 and travelling as fast as stated, with the sizes of both the asteroid and the earth, with its layered construction, wouldn't the asteroid have split the earth in two, with it velocity and mass, and the earth thin surface crust, it softer inner layers, would it be just a huge planet exploding, I can picture the earth surviving if there were a series of smaller asteroids hitting the surface, but one large one like the one at 22:18 all I see is the earth disappearing, ?

[@andycano5756]

The Earth is thousands of miles thick, with a dense core. A six mile piece of shit is insignificant to descend very far.

[@accessaryman]

there is a lot to learn about mass and velocity, a solid mass such an asteroid 6 miles long crashing onto the earth crust at 3 to 4 miles thick with a soft molten center and its hard core you'd get a huge splatter, and the dispersal of bits of earth through out our galaxy, fairly simply id have thought, maybe you'd better research the earths layers, before you tout your knowledge.

[@mrs.schmenkman]

Well...the calculation of the size of it is based on the hole it left. Maybe you could calculate the size yourself?

[@larrydaniels6532]

Owen, the Earth is 8,000 miles in diameter, the asteroid is 7 or 8 miles in diameter, in relation to the volume of the globe, it is basically a speck. A speck with the kinetic energy of a trillion Tsar warheads. The atmosphere was that of blast furnace, everything that could burn, did burn. Every land-based animal was dead in less than 12 hours, only burrowing animals and sea creatures lived to see the next day.

Man this was a well produced documentary. Not that I learned something new, but I think it covered pretty much everything concerning the KT-impact event. Well I guess widescale volcanic eruption was left out as a possible contribitor of the KT-extinction event. It would make sense to me if an impact of that size would trigger a shockwave through the earth and trigger some releases on the tectonic stress zones and heat up some volcanic chambers. Well since I don't have a scientific background I wouldn't know the impact would be big enough for such event to occure.

[@periurban]

It may have happened in a smaller way about 12,000 years ago, possibly accounting for the various legends of the flood. There was likely a vast conflagration after an object nearly a mile across hit Greenland when it was covered with ice. The resulting debris wiped out most life on North America, which might explain why many large species disappeared. The impact also may have damaged human civilisation, setting it back to the stone age. Some say the megalithic structures we find in Egypt and South America predate this impact.

i witnessed something strange around 10 years ago when i was living in San Diego . I was driving down one of the main streets with a perfect view of the sky in front of me, and this was around 9 pm at night which was pitch black sky and all of a sudden a giant circular ball reminiscent of an asteroid which has a blue trim and was black on the inside, was ready to come into the earths atmosphere when it bounced 3 times off what looked like a forcefield around the planet then went back into space ... what could that have been ? if it was a meteor , wouldn't one bounce have been sufficient to send this thing back into space? what would make it bounce 3 times before it finally left . This was a very real experience for me and i still have no answers

[@samwell2386]

[@Token528]

@MARK FAUX 1. Compared to a full moon : how large would you estimate this silhouetted object being ? it was big, hold your fist up to the sky, about that big 2. How long did you witness it ? Few seconds, mins ? few seconds was all there was 3. Do you remember what part of the San Diego sky it was in. i was driving down Rosecrans toward the freeway , i was going downtown 4. Did it have a traveling direction : South to North, North to South etc ? just came at us, and bounced a few times then shot back into space 5. You said it was around ten years ago : Could it have been in October of 2013. When the entire USA government shutdown ? Since you were in San Diego at the time you should remember that. No it was more than 10 years ago ... sometime between 2001 - 2006 .. best i can tell you. Please please try to remember as much as you can.

[@bernardedwards8461]

You obviously saw a large bolide striking the upper atmosphere and doing a few skips like a stone bouncing across a pond. It was travelling too fast to be captured by the Earth's gravity, which was perhaps just as well. Penetration to the ground would have produced an explosion similar to the Chelyabinsk meteorite, which did a lot of damage a few years ago. I once saw a smaller one which probably impacted the surface, but shone as brightly as the moon for several seconds and lit up the countryside. Two hit the sea for every one that hits the land.
