  • Que loco! Já pensou se um bixo desses pega nóis!?

  • very interesting thanks

  • interesting video and very informative

  • some great inforamtion here thanks

  • The generally accepted value for the energy expended is about 70 million megatonnes, but that's +/- 50%. 70 teratonnes, TNT equivalent.

  • I don't think the KT event / dinosaur extinction was caused by a meteor, I believe it was caused by a giant TOILET BRUSH crashing to Earth !

  • This impact killed all dinosaurs. Of course there are other theories about their extinction, but this is the most accepted one.

  • Scientist say that the asteroid could have been as much as 9 miles in diameter and hit with 1 billion times the energy of the nuclear bombs that hit Japan. That seems like the would cause mass extinction immeadiately.

  • 1:10 looks like Independence Day.

  • They should call this "The Big Chingaso" since it happened in Mexico.

  • The Black Marker was found underneath the crater. Nah... thats just a lie.

  • fist ppl will survive this millions problly will die but humanity will surivive this or even bigger impact . but i dont know why ppl still consider that a dust cloud will go on for that long is still a heavy dust . and what more i think for real KT event there will be many factors before that and ofc the dinosaurs have been big and one missing chain from the food chain may topple the whole food chain and i wonder have someone tryed this impact in small scale of sort

  • The trajectory was supposed to be at a fairly low angle so the impact and the crater would look asymetric not like in the video. It is highly unlikely that an objects of such size would come straight down as shown, otherwise nice video.

  • @medeerbeer: As it turns out, gun tests have shown that the angle is not very important in determining the crater shape. It does determine the ejecta shape, but that's eroded and long gone.

  • i know those Tsunamis were 100s of miles high. 0_0

  • @k5lta how do you know, were you there ?  LLLOLLLLL

  • @k5lta: Hundreds of miles? Into space? No. A kilometer high over much of the Earth?  That's possible.

  • As destructive as it was, this impact event was the best thing that ever happened to us. The next impact event on such a scale will be the worst thing. Everything's relative.

  • what about the megatsunamis? what about the global wildfires? earthquakes? volcanic eruptions? they all would have been occurred due to the impact. this visualization makes no mention of them...

  • @teeoh38: No. the best visualization/description I've found was in Animal Planet's series about extinction events.

  • BTW, for the calculation of mass, you'll need to know the density of the asteroid. The average asteroid density in the solar system is commonly assumed to be 2500 kg/m^3, but this is also known to vary, further adding uncertainty to the calculations.

  • well the basic physics lying underneath such an impact are still the kinetic energy physics. therefore you can use the KE= [m(v^2)] /2 equation. m is mass in kg and v is velocity in metres/second. To convert it to megatonnes, you divide it with 4.184x10^15 as onem megatonne TNTe is 4.184x10^15 joules. The uncertainty in the calculations results from the fact that nobody is quite certain about the size, velocity and composition of the impactor.

  • I wanted to see the 3,000 foot tall wave

  • @xfilesmanson Yes I was looking forward to that too...:( Can anyone recreate the wave?:)

  • yeah, bring it on

  • Take a look at the hypothesis called The Impact And Exit Event. I read the book last fall and as far as I am concerned the hypothesis actually proves that a far larger catastrophic event must have occurred in the Gulf of Mexico - with Chixculub quite possibly being the epicenter. The hypopthesis is available at theimpactandexitevent . com

  • Very interesting video, thank you for sharing. I just have one question. Obviously, if this asteroid crashed into the water, there would have been tsunami waves that resulted from the impact. Is there an estimate somewhere of how much water was actually displaced?

  • @M4d150n2596 Id like to know too. must have been an incredible amount. & would have caused such big flooding in nearby continents.

  • @M4d150n2596 Not too sure about the amount of water displaced, but the waves would have been anywhere between 2000-3000 ft high, and apparently went at least half way into Texas. Imagine watching that come towards you!

  • @kasparov9 especially at hypersonic speeds...

  • @thefreecypriot: No.  Except in the immediate vicinity of the event, the speed of just about everything material is limited to the speed of sound. This has been shown in atomic blasts; once the shock wave gets about a half mile from the center it is slowed to the SoS.

  • @puncheex i'm not sure i get exactly what you mean. can you clarify please ? i wrote down my last comment so long ago that i almost forgot what i was saying...

  • @thefreecypriot: kasparov mentioned high tsunamis in Texas, and you added "especially at hypersonic speeds". Objects can travel supersonically through an atmosphere only with great difficulty and energy expense; unless driven, they quickly decelerate to sonic speeds. Something like a wave would break up into vapor and cloud droplets.

  • @puncheex sorry, should have made myself crystal clear on what i was referring to. What i mentioned when i said hypersonic speeds was the heaving wall of water and rock vapour that detonated from the impact site at hypersonic speeds. A Uni of Wisconsin research dating to 2007 (might be outdated) rated the estimated speed of the shock front at r=20km at almost Mach 30.

  • @thefreecypriot: That's certainly possible; but what would it be when it got to, of, 150 miles, about the size of the crater? Of course, most of that would have been ballistic in the first place, likely rising completely out of the atmosphere.

  • @M4d150n2596 For a good visual, imagine a wave twice the height of the eiffel tower.:)

  • I hope I'm not here in 35 million years. I don't want to go through anything like that.

  • NationalGeoGraphic said it was like a Russian and a American Atomic-Bomb at the same time, that x10000 was the power of this impact.

  • if the asteroid did impact in the ocean, shouldn't the seawater rush back into the superheated crater, evaporate into steam and create an enormous mega storm over the ocean?

  • @Mrcryptidsarereal no. what you said is probably correct for lower speeds and lower mass. but in the case of Chicxulub, the asteroid plunged directly into the rock underneath the ocean and the abrupt arrest of its motion suddenly converted all of its kinetic energy ( which was colossal) into thermal energy, evaporating the rock to such high temperatures that it exploded outwards with unfathomable force. Due to the sheer violence of the impact, solid rock behaved like a fluid...

  • you did a phenomenal job awesome video =0)

  • Finally...Realism...Facts!!!

    Im sick of seeing an asteroid the size of the moon splitting the Earth in two and creating a huge fireball that consumes the solar system >=( its never going to fucking happen...

  • The impact was 100,000 megatons of TNT.

    The largest bomb, was the Tsar 50 megatons of TNT.

    That's 2 million times more

    So, I don't know where you got 300 million from.

    Even today we could possibly, build bombs in the excess of 500 megatons.

  • @Agnes135

    Someone beat me to it, should of read the comments.

  • in your hands and actually hold with it the history and ancestory of something you never will ever see with your eyes, it changes everything. You, foxairfield, are a moron. Thankyou, and goodday!

  • Comment removed

  • FoxAirfield..."if dinosaurs ever existed??!" Are YOU SERIOUS? I've dug on my own and located several fossil sites here in North Carolina. I have bone frags that are not human or animal of any close time period - fossilized into stone you moron. Not only that but I have bellumnite (like a squid) fossils from a creature that existed during the Carboniferous period. Also becoming extinct at the end of the Cretaceous Period, time of the K-T mass-extinction. Learn your facts! When you hold a fossil..

  • @Sixpackjeanie lol you have dinosaur bone fragments? thats rich...

    a relatively small asteroid hitting this earth wouldnt disrupt the earth either. it would hit the earth, penetrate into the ground, and thats about it

  • @FoxAirfieldMaverick

    We're not talking about the freaking MOON here. Live in denial if you want, we've SEEN firsthand what big space rocks are capable of (Shoemaker-Levy 9). There was a fifty-kiloton upper atmosphere airburst in Indonesia last year that shattered windows on the ground, and that was from a rock less than ten meters in diameter (watch?v=yeQBzTkJNhs). Those people should be thanking GOD it didn't reach the ground. Can you imagine what a rock the size of Manhattan Island could do?

  • @MYApictures they completly over exagerated the effects of shoemaker levy. that planet swallowed the asteroid the same way the earth would

    also what are you saying about indoneasia? they make windows on the ground or something....whatever, im not interested

  • You shoulad actually change the part about 300 million nuclear bombs. That is misleading especially considering the variable power of various nuclear weapons. Best to state in megatons and give a refference. Good vid by the way

  • @accountok01

    Would if I could, friend, but I didn't make the video. Still, thanks. It's the best visualization I've been able to find to date. I included some information I was able to find in the video description, including a link to an Impact Effects calculator published by the University of Arizona. It's sobering.

  • @MYApictures The 300 million threw me off too. To bad alot of people dont know about megtons as a grading for Nukes. (Im not saying you didnt know, i mean most people in general.) Their is alot of conflicting figures BUT they are all relatively close and accurate. The U of Austin Texas/Jackson School of Geosciences has some good figures published. Very well done here thanks.

  • @MYApictures I believe the estimated yield was 10 to the eighth power megatons making it 2 million times more powerful than tsar bomba, detonated by the USSR and with a yield of 50 megatons. the soundwave from that bomb alone was able to be detected the THIRD time it passed around the earth, so needless to say, very big, and this impact makes it look like a firecracker.  excellent video btw

  • @accountok01 Actually scientists estimate the impact of the Chicxulub crater to be equivilent of 100,000,000 megatons of TNT. The Tsar bomb, the most powerful nuclear weapon created by man, was only 50 megatons. With that information it's closer to 2 million times more powerfull than the largest made nuclear device.

  • @Ev3ntH0rizon Actually it was between 100 120 million Megatons. Wiki isnt the best place for your checking

  • @accountok01 The impact got a total yield of 15.9 teratonnes or 15,900,000 megatonnes. By comparison, the most powerful nuclear bobmb ever tested was the Soviet Tsar Bomba with a yield of ~58 megatonnes. The impact then has a yield of ~27400 Tsar Bombas. Figured you would like to know.

  • @thefreecypriot Wiki states that the asteroid yielded 95,602,294,455 kilotons of tnt. What's your source regarding the yield?

  • @kasparov9 actually i just realised that my previous estimate was hugely erroneous. Based on the estimated ( and probably globally agreed ) asteroid size of 13-14 km, which is what you should have to gouge a crater 180 km in diameter and a minimum speed of 22 km/s, you could calculate that the total impact yield was approximately 315-360 teratonnes of TNT equivalent which is 315 million million tonnes of TNTe.

  • @thefreecypriot I've been checking out the facts from various sources, and all seem to differ a little in their estimates regarding the yield of the asteroid. Wiki states that it was 10km wide, some other sources including yourself are saying 10-20km. Excuse my ignorance but how do you calculate the yield exactly? It's an enormous yield whichever way you look at it.:)

  • @accountok01 I agree it produced under 50 million small bombs.

  • Comment removed

  • @accountok01 Not entirely accurate. 300 million nublear bombs would have done far greater damage.

  • @FoxAirfieldMaverick

    The element you're thinking of is iridium, and they've found a layer of it worldwide, most concentrated at the site of impact. Shocked quartz and compression (gravity signature) draw a crater ~180 km in diameter. You're oblivious to evidence that's been documented and discussed for decades (also, going out on a limb to say you're taking some young-earth creationist angle with the dinosaur thing, that wasn't the most Christian way to open your argument in my humble opinion.)

  • @MYApictures thats right, iridium. however no evidence suggests that iridium levels are any higher in chicxulub- only that worldwide there is a thin layer of clay from way back containing extrememly high levels of iridium. again, no evidence suggests this region of the world was struck by an astroid. and if it was it wouldnt create an ice age. its total crap and scientists should stop speculating until they have concrete evidence- like large chuncks of this alledged asteroid on a table

  • @FoxAirfieldMaverick actually, the very existence of iridium is proof that we got sledge-hammered with a big asteroid in the past because, you see, iridium is incredibly rare on Earth. There's probably not enough iridium to fill an Olympic size swimming pool and it's quite abundant in asteroids. There are several hypotheses to explain such an abundance at the particular layer but the only logical way is an ELE associated with an extraterrestrial impactor.

  • @thefreecypriot

    There's not even enough gold in the world to fill an Olympic size swimming pool...

  • @MYApictures actually the crater is larger then once thought. Current estimates based on futher study place it at around 280-300km in diameter. You are reffering to what they thought was the outer ring but was actually an inner wall. FoxAirfieldMaverick is clearly an idiot that cant read a book or find out this info.

  • @MYApictures Foxaurfieldmaverick, is obviously trolling, way to be dumb and respond

  • @FoxAirfieldMaverick LOL you really dont know what you are talking about. Its actually funny but sad at the same time.

  • @FoxAirfieldMaverick I really hope you're kidding about the dinosaur comment? Let me guess, you believe that Jesus walked on water, turned water into wine, healed the sick with magic hands. I can prove that dinosaurs existed...can you prove jesus did all those things? NOPE!!

    If you believe in Jesus then you must think Santa comes on December 24th and delivers you presents every year.

  • @brendo123 when i was 7 years old i actually thought dinosaurs and santa existed. silly me

    the bones you see being excavated in digs have been planted by museums. anyone with a lick of common sense knows this

  • @FoxAirfieldMaverick Your total fucking bullshit

  • @FoxAirfieldMaverick Well, now they will:)

  • wheres the 30km deep crater? wheres is the 500 km high tsunami? this simulation shows puny aftereffects. it does not show the shher devastation of the impact.

  • That's it? That's the man killing crater effects? lol. Why are you people afraid of anything? Human beings can survive 5 years under ground and such. That ain't nothin. Think about it a little bit. We can all survive on meat we grow in our advanced farms indoors and our own veg/fruit growth.

  • Comment removed

  • It's not likely to happen soon, but it's not something to be blithely dismissed either. The last time this happened, 65% of all species died out - and those that survived did so just barely. The human species might survive if this happened today, but we'd likely lose more people in the first hour after impact than the combined sum of every human war.

    This video simplifies a great deal. Poisoned air, poisoned water - it would be felt for lifetimes. I'd suggest reading about the Siberian Traps.

  • @MYApictures

    Stop pulling numbers out of your ass like you're some kind of scientist. I have a PhD from the University of Berkeley in Astrophysics and I know for a fact you made that 65% of species right off the bat. During the K-T Extinction nearly 65,000,000 years ago. 99% of Species died not 65.

  • @Romansteel13

    Get your stats right. I can't speak for this guy's 65% figure, but yours are worse. Over 99% of ALL species that have EVER lived since the beginning of the fossil record are now extinct. Roughly 90% of species living at the P-Tr boundary (marine hit worse than terrestrial) died off in an extinction event worse than the K-T event.

    If you're going to spout fictional credentials on YouTube, at least try not to make a complete ass of yourself in the process. You give PhDs a bad name.

  • @Romansteel13 i cant see any species being effected outside of a 100 mile radius of this alledged comet. before taking to heart what your professor told you, think about if for yourself

  • @AxRhea88

    I love stupid Americans like you. If a Chicxulub cretaceous like bilobe were to a impact Earth. not only would the stratosphere and biosphere not stop it. It would cause a mass extinction of all living things. It doesn't matter if you were underground, the radiation caused would had killed you by now. I understand that you're American and you're ignorant so i'll give you a pass.

  • @Romansteel13

    Also, top marks for displaying anti-American bigotry against another user when your own profile says that you're an American. But then, I guess that that's all an education at the People's Republic of Berkeley is good for anyway.

  • First class visualization. 5 stars from Poland.

  • holy shit! im scared a little bit'

  • so we still got another 35 million years for the next? and there I was getting worried.

  • isnt this the asteroid that wiped out the dinos? :D

  • amazing video 5 stars

  • woah O_O! 5/5

  • Great vid. I've been studying the seismic profiles of this crater. Sounds interesting. It is.  But difficult :(

  • Awesome choice of music! Whats the name of it, btw?

  • I think it's from the soundtrack of "Event Horizon," but I don't know for certain.

  • we're all doomed! doomed I tell ya! doooomed! if anyone needs me, I'll be in the kitchen with a bag over my head.

  • really should upload this in HD.

  • Not bad, really nice video and i faved it. The only thing your forgot was the global fires.

  • Apparently the asteroid came with an orchestra.

  • lol

  • @mikeshepherd I always hope the appocylpse has music that comes with it. preferably carmina burna, the 5th symphony, or a john williams score
