Simulation of asteroid killing dinosaurs:
Scientist: Boom! Gorgeous.
Hitting "head on" (aimed at the center of Earth) should be expected to be the RARE event, some random angle would be common.
not really since gravity comes from exactly the center of the earth which would make any object not fast or big enough to withstand that gravity hit head on aiming at the center of the earth.
@@fortisvoluntatis1417 at the speeds these impactors come in at the earths gravity field has no meaningful chance to 'normalise' their angle of impact. The reason a lot of craters are round isn't from a preponderance of 'head on' but from the massively energetic impact creating an actual detonation at the point of impact.
@@mrpirate3470 this point of impact should not be a point - it schould be a line..
also take a look at the moon - there is much less gravity and they are all round - so this is cleraly a lie, that they come from asteroids impacts..
@@spirituelleOOinfo these impactors aren't like stones thrown into sand. They Explode, in the kiloton to megaton range at least. These leave round craters exactly as any other explosion would
@@fortisvoluntatis1417 the path the asteroid follows is due to Sun's gravity not Earth's
People in the comments, I'm addressing you: There's no need to be so aggressive and cold-hearted to scientific exploration. If you really can't appreciate these scientists' passion and profession, then simply SHUT UP.
Its literaly just a fucking rock hitting the ground also chixulub impacted the ocean but they did it on sand so even if its even a simulation its not accurate
@@juliodwisa2765 the asteroid hit in very shallow water (600 meters max) so the main reason the dinosaurs went extinct was all the rock and sand. If it hit in the middle of the ocean (thousands of meters deep) a lot of the asteroids force would have been absorbed and some dinosaurs on the opposite side of the planet might still be alive, as it was the cloud that covered the sun that caused the extreme heat (from 150-200°C) that made it extremely hard for the dinosaurs to survive. If it hit the deep ocean, there would be a lot less of that cloud that covered the earth so the temp would have probably only reached up to 60-100°C which would have been a lot more survivable. So the experiment would have been less realistic in water, than what was used.
@@danielmcgurk4991 wow you replied pretty late...
Listen even though its shallow water its *shallow* water using a lil bit of water could've been fine
@@juliodwisa2765 no that would still not be realistic because of the surface tension.
Listen ...I was there , you are all wrong ! the dinosaurs predicted humankind and build spaceships and left earth before the asteroid ...yes asteroid hit...prove me wrong !
People do not often think of the atmospheric effects of the impact. It would explode as it entered the atmosphere, making a plasma fireball over 6 miles wide. This entry event was similar to a hot-dog shaped nuclear explosion in the sky before it smashed into the ground. Pretty weird to think about.
just drop nokia 3310 and you can simulate the realistic impact
😂
The Nokia will kill every single person, and 99.95% of all life will be dead. Queen Elizabeth II will survive, though
And then you'll be able to do it again

Effects of Asteroid Strike:
1.Towering Tsunamis
2.Powerful Fireshockwave
3.Temperature Rised over 100 degrees Celsius
4.Ejecta Cloud Raises Temperature
5.Debris rain down and cause fires
6.Magnitude 11 EarthQuakes
7.Debris blocks out sunlight causing short cold period
8.Dinosaur who survive struggle to find food
9.Dinosaurs die out
Hmm... yes 👾👾👾👾
Hundreds of degrees
you know this is legit nasa science when you see banana on a work desk @1:21
XD
It's for scale.
Eugene lim What are you trying to say?
I don't get it.. why bananas?
*ArE tHoSe BaNaNaS tHe AsTeRoId ThAt KiLlEd AlL dInOsAuRs??????*
the asteroid strike triggered volcanic eruptions globally; including super volcanic eruptions. prehistoric remains have been found in layers of ash. the strike also more than likely triggered temp changes due to debris going into the atmosphere
This job seems incredibly fun and satisfying in slow mo
1:26 rip t-rex
1:38 - 1:44 reminds me of scene in Rogue One where Death Star destroys Jedha
Political Correctness
Me too
Makes sense.
XD
also reminds me of Rogue One where Death Star destroys Scarif.
that was a mining accident
I only came because of the impact
Asteroid belt: Hey Earth, Catch!
Earth: i dont have hands *kaboom*
For some reason an ad when I started a video was an Jurassic park ad and it showed meteors crashing down
Jurassic world fallen kingdom
The shockwave of the impact would have done considerable damage too
Shoemaker levi 9 changed the outlook on how asteroid strikes would effect earth.

and no coffee
I WANT MORE... why is it only 4 minutes TT

I've always been scared af about things like these. Yet I'm not as much anymore, as where it's an issue for me. I find the whole thing of the world ending life all at once, both frightening, yet beautiful as well. We all go together in one big... bang.
Tbh I feel like instead of going out with a bang, We may just fade out of existence but I can also just imagine going out with a bang like we started
given we can't watch the episode from the link given. It is criminal that you didn't upload the section with the ice. That is by far the best bit of the show.
Idk why but I find these kind of videos really satisfying
This was cool and what I hoped for. Its the closest thing today consider a pretty solid response.
Great video
What a nice job!
It means depending on direction, it would have more devastation towards the angle it struck.
it also created a HUUGGEEE mega tsunami
The largest Tsunami
In The world
No. The water was too shallow to create the tsunami you probably have in your mind. It was around 300 feet high by most estimates. If it had hit in deep ocean it would've been ~3 miles high.
@@audilicous the closer it comes to a coastline the higher it gets.. thats the problem
@@fortisvoluntatis1417 Correct, but it will not become higher than the height of the water it originally entered. Thus, it would be limited to what I said before. The sea it hit was extremely shallow.
Me watching this for science class: 👌
So you're telling me that if the asteroid landed vertically, the dinosaurs would be alive?
How many sound waves would this exert?
Thats why i love science
I want to go see it after coved 19
Earth isn't as safe as we once thought.
Yes, it's the people and their ideology.
@@jimmatrix7244 on god
Why would they be limited to an asteroid hitting the planet directly straight? That's absurd.
Showing this guys flat model of the earth will get the flat earthers all moist
Skipping stone meteor.hit the Gulf bounced once the spin on it from the first impact wiffel affected it to hit Arizona from a high ark.and magnetism from the first hit.
just curious but how were all of the fossils not destroyed in the prosses as well
Do you have to have ads?
You had me at death an destruction
The bore hole evidence at the crater off the Yucatán peninsula along with the KT boundary is such overwhelming evidence, that any other theories seem ridiculous. Obviously, we’ll never be able to claim 100% certainty, but that’s normal for widely accepted scientific theories.
I admit, when I watched Rouge One.....
I thought of this special.
I think Rouge One took the idea of the dinosaur killer impact and just used the Death Star instead of an astroid!
They made rouge one BEFORE the dinosaurs went extinct, so its most likely the dinosaurs ripped off the deathstar, not the other way around.
Cue the dramatic music, no mention of what scale, no mention of what the models are composed of, no mention of how big the crater is
If this is considered science then I will eat my shoe right now
who's the narrator John Lovitz?
😂😂
No its Tanos
According to the web site IMD it was Eric Loren. He was the narrator of six episodes in 2014.
Now make that gun 300x bigger and put it together one piece at a time in low earth orbit and you have yourself the most powerful weapon ever made
Now increase the size to an asteroid for the most realistic impact demo
they probably used the same force of that so believed meteroid but not the same width in size so I wouldn't take it by precision with these tweakers
Watching the movie "Greenland", umm, yeah, we should have geostationary space stations,
as a survival strategy, because not all catastrophies can be averted with a bunch of nukes.
The space stations could even be movable, to avoid extreme high ejecta.
It would make an awesome series with challenges to overcome when trying to make life anew,
once the dust settles and the Earth's surface is habitable again.
Throw in a combo of Mars settling for an alternate movement.
Some theoretical sciences on recreating species of plants from DNA sample banks,
digitally stored, in a vast databank aboard the station(s).
"Afterglow", because some parts may yet need resolidification into non-molten state.
U sound like Grandpa Lou =)
I keep wondering about a huge volcanic explosion..say from the young Krakatoa Island
The dust from the inpacked on the earth went around the earth and that's how the dinosaurs dead
0:47
JUST DROP A CHOCOLATE IT'S GONNA WORK
1:43 Except that the impact that created both the KT event line and killed the dinosaurs,
didn't strike vertically, but diagonally and resulted partially in the Gulf of Mexico.
It struck at a bearing of NW, about 60 degrees upward-ish..
3:36 Nvm, you got that.
You can find out for more certainty, by measuring the large debris around the Earth,
for the spread.
Larger pieces can't stay up in the atmosphere for weeks and have a ballistic trajectory,
which is then more common near the impact site, and with certain density covering.
Then when the amount of debris in larger chunks is made into a density chart,
with similar indication of large chunks density, you can match that to the
simulation, until you get a similar result on angles of impact with the simulation.
Ofc, it still won't be as exact a match, since there's no atmosphere involved
in the simulation, which would disallow faster deceleration due to air friction..
This is different from measuring the KT line's thickness.
t's checking it for larger debris parts, not dust.
Still more interesting would be drilling a hole in the ground somewhere,
getting a deep soil sample, and finding out why part of the US's mountains
and the San Andreas fault line exist, but also finding out that some
tectonics still exist because of an event that happened millions of years ago.
A tectonic plate set in motion by such an event does not come to a halt in a year or two.

Beautiful formation, do it again.
If the asteroid had hit head on... The crust would have cracked, and earthquakes unimaginable would have shook the world. And no... Not saying it would have literally destroyed the planet, I mean Earth survived a head on crash with Thea... So no. But the idea is that if the meteor made this much damage at a shallow angle... How much more would have been from a head on collision
People, including scientists have a hard time wrapping their head around the immense energy released by the impact.
The excavation of the crater took 3-5 minutes and both the impactor and earth under and around the site were vaporized, a mountain range of material was vaporized by heat hotter than the surface of the sun.
If you were anywhere within line of sight of the plasma ball you would be blinded and set on fire. You wouldn't have seen anything but assuming you were wearing a big silver reflective fire suit and tinted welding visor (assuming it could dull light this intense to something that won't blind you) you'd have barely had time to register the entry if at all.
If you were on the Gulf Coast in what is today Georgia or Mississippi and wearing said suit, the plasma ball would appear the size of a soccer ball held out at arms length.
Unlike Hollywood depictions no large boulders would rain down, it was almost entirely vaporized or reduced to dust. Further from the impact, out of line of sight as the plasma ball is behind the horizon you'd see the curtain of incandescent material rising and spreading out,after 30-40 minutes it would envelop much of North America.
The heating would be rapid and begin setting flammable material alight. Forests would burn.
About the same time the magnitude 10+ earthquake would strike. Liquefaction of soil would occur and start to swallow things up, even well built bunkers would fail meaning survival is unlikely as either the bunker implodes or the escape tubes are severed or buried. Even if these things do not happen, the shaking would be so violent people would suffer fatal injuries like heat trauma and broken bones.
Vulnerable facilities like nuclear power plants would suffer immediate failures as coolant plumbing to their cores would fail. Their containment systems would collapse and having suffered coolant failure would rapidly overheat and rupture, exposing their burning cores to the atmosphere. No one could make efforts to remediate the problem or get coolant to the reactors as they would be crushed by falling debris or simply be unable to walk or work amid the violence of the shaking.
Buildings would collapse, hundreds of millions not already charred to death by the flash would now be buried or crushed as their homes, offices and other structures collapse on them. Cities would see pretty much all of their tall structures fall. This would be a global event. About 1 hour after impact the entire planet would be shaking violently.
The magnitude 10+ earthquake would trigger volcanic eruptions as it spreads out adding greatly to the effect. Yellowstone would erupt.
The tsunamis would take the longest to effect the planet, some would take many hours to days to hit land as they cross oceans direct from the impact while others would be induced from undersea landslides, the global earthquake would trigger localized earthquakes and plate uplifting that would cause additional localized tsunamis in addition to the primary earthquake, submarine volcanic eruptions would likely cause some tsunamis as well.
Over a period of 30-60 minutes much of North America, all of Central America and a significant portion of South America would be hit by the blast of overpressure, unprotected animals and people would suffer collapsed lungs and other hollow cavities. Ruptured eardrums absolutely.
Between 1 and 2 Billion people would be dead by 1 hour of impact.
An excellent video can be found here, in my opinion it is very conservative in its estimations but very interesting to watch. It does not make mention of eruptions, additional tsunamis ect (that's ok, hard to predict which faults and volcanoes will go) but gives a pretty solid estimation of the impact effect.

Where did it hit tho, I have someone saying it’s fake because we never found a meteor I know about Chicxulub crater but idk if that’s right
And the guy said the great flood killed the dinosaur, he was trying to prove Noah’s ark
@@zakiry8634 it hit the gulf of mexico, no meteor was found because it was vaporized on impact.
Miguel lopez ok thanks
Yeah, whoever tried to tell you that is full of it. The meteor mostly vaporized from the tremendous forces involved at the point of impact.
@@zakiry8634 some of them were killed by the tsunami created. Trust me, he wasn't trying to prove that ridiculous fairy tale.
they found new news of dinos and fish and mosasaurs and eggs at the time of impact all mashed together in rock, that brought me here...lol tidal waves played big part also
3:42 that crater isn't egg shaped. And I don't think the one at Chixulub is either. And why would a 90 degree impact angle be the norm? There is a wide range of possible angles for impact, it isn't especially likely to be a right angle. The scientist in this video is great but is it possible I sense some sloppy work by the uploader?
can anybody explain the flash seen upon impact?
heat from friction, or maybe sparks from sand.
It is indeed heat. Energies involved in a collision at 4km/s are so huge, that things melt and/or evaporate. The flash is literally plasma - a cloud of evaporated sand and impactor debris at extremely high temperature.
Per the narration, the ball is traveling at 12,000 mph (over 5300 m/s). Kinetic energy is proportional to velocity squared, so for a 1 gram ball that's over 14,000 Joules (almost 4 Watt-hours, enough to light a 100-watt bulb for two and a half seconds). It didn't say whether they evacuated the chamber (if they were simulating an impact on Earth, probably not), so some of that light is plasma from the ball ionizing the air as it rips through. On impact, some of that energy goes into the ejecta, but most of it goes into heat, light, and sound.
Now, scale that second impact up to the Chixhulub impactor, something like 11 km in diameter and massing on the order of 10^15 to 10^17 kilograms. At that same impact velocity, it would have release on the order of 14 _sexitillion_ Joules, or on the order of 4 _quintillion_ Watt-hours. Think how far that wave of hot debris would have traveled.
1:25-1:35 OOOHHH GORGEOUS!!! 😂😂😂😂👾👾👾👾👾
Rip dinosaurs
You can tell someone is a pyromaniac when they call explosions gorgeous
Simulation of asteroid hitting a flat Earth
Due to the size of the earth, the small area that they are representing would not appear curved just as earth does not appear curved from our tiny point of view. If you were to look at the edge of a circle zoomed in enough you would not see much curvature at all.
@@ToastyEggs It was a joke pal
King Rafa oh, I didn’t realize. Sorry about all of that nerdy stuff. :/

Nice simulation. But the actual not as simple like that. So many parameter need to be calculation. But nicely.
Maybe it could be something else that fallen from space like🙄ug

No it didn't, it just made many people fear something pointless to fear, like fearing the day of your death.
How far into the earth will an asteroid travel after impact? Can a comet go through the sun? There has to be something looking out for this planet.
Depends on size and makeup of asteroid, hell no, and Jupiter is kind of an asteroid and comet catcher that helps Earth. It's massive gravity pulls in a lot that might otherwise make it into the inner solar system where we live. Hope that helps a bit.

Imagine if the money wasted on this guy's "experiment" had been spent on a worthy project instead. If I had the power, I would put him and the bureaucrats who authorized his grant in prison for several years to think about it. He literally learned nothing that couldn't be duplicated by firing a .22 into a mud puddle.
The thing is, this object was going at 4km/s (much faster than a 22.) Also, you can see the intense heat and plasma caused by the friction of the object.
Domino the Dominator
And for all that effort and expense what was added to the annals of human knowledge? That a high speed impact spreads debris up into the air and all over the place. I never would have guessed.
Sporkmaker5150 Dude, holy crap, do you get angry at everything? This is an accurate representation of what would've happened 65 million years ago, and you're here complaining about it?
Domino the Dominator
I wouldn't say I'm angry, just puzzled and frustrated that this pseudo scientist was probably financed by tax dollars for his "experiment". Tell me this, was there any possibility whatsoever, any at all, that the result would be anything other than what we just saw?
Sporkmaker5150 Well, you have a point there. I didn't know that this was paid for using tax dollars, and you're right, it probably wouldn't differ from the last experiments.
Amazing!
Hey
sometimes i just wish Giant asteriod/meteor will hit the earth soon.
1:26
This is a $100,000,000 experiment you can do for free with a rock, at the beach, and a smart phone. It's still cool to watch though.
You can throw a rock at a few miles per second?
This is so cool :O
I wonder if its possible that the asteroid caused the tectonic plates under the earth's surface to become unstable and it caused earthquakes and volcanic eruptions around the earth? Im guessing this was already pointed out, but maybe they should create a replica of under the earth as well with fake tectonic plates and see what those would do to volcanos and the earth's crust. Possible testing? If anyone knows of a video like this please let me know as I am interested :] thanks.

They always mention the soot/ash blocking out the sun...but what about the heat from the initial impact? If you were 8,000 miles from impact, how much would the heat rise? Would you be deafened from the shockwave? Also, I wonder what the sound would BE like. Would you be blinded from the flash, at 8,000 miles away? Or would you have to wait for the soot/ash to end you?
How do they cause such explosions like bruh
@Blob B oh wow thanks
No creo que un meteorito de 15 Km haga todo el daño que se supone, y mucho menos afectar hasta el otro lado del planeta, ni por Pangea que haya sido. Creo que más influyó alguna variación climática generada por el impacto de un gran meteoro haciendo que el eje de la tierra se desvíe aproximadamente unos 90 grados haciendo que donde ahora son desiertos antes eran polos; talvez aceleró también la rotación de la tierra y cambió la órbita de la Tierra ya sea más lejana o cercana al sol afectando la temperatura corporal de los saurios. Estoy seguro que no fue en el golfo de México. Para que suceda una extinción de tales magnitudes y efectos debió ser más cercano a las áreas con más fauna de tales especies y debió ser un meteoro de mucho más tamaño. Y el único rastro de tal magnitud que he podido observar en los mapas terrestres se ubica con centro en la región de Xinjiang y el Tíbet, impacto que generó la cordillera perteneciente a Jamu y Cachemira, Uttarakhand, Nepal, Bután, Arunachal Pradesh, y el otro impacto haciendo centro en Bratsk generando el lago Baikal y la cordillera sur que circunda a Mongolia. Nada más hay que detenerse a observar las cicatrices antiguas de posibles impactos que la Tierra sufrió en algún período en el que el sistema solar fué bombardeado por millones de asteroides y meteoritos hace miles de millones de años.
