the 20km wide one was the one that killed the dinosaurs.
65 million years ago
It’s awesome that it hit so close to home.
@@willvr4 yes, Chicxulub is the name though. in the video it said the frequency that it could hit. the last time was 65 million years ago when it hit the gulf of Mexico and killed the dinosaurs
@@cosmicthespider7974 you live close to the impact zone? how awesome. i believe there gulf of Mexico was created as a result of the huge crater.
@@TheAngryScotsman. I think the Gulf of Mexico was already there. And I think it landed halfway on land and halfway on water
The event you asked when it last happened was at minute 4:31 called the Tunguska Event, it happened on June 30th1908.
The last impact approaches the one that created our moon, though the object that hit us was closer to the size of the planet Mars rather than merely Ceres. The Earth originally had no moon and was much smaller than it is today. This smaller proto-Earth collided with this planet sized object and the collision shot enormous amounts of mass from both the proto-Earth and this other object into orbit around the now more massive Earth. For a brief period, the Earth had a ring similar to Saturn's made from this orbiting debris, but this quickly collected together to form our moon.
So why doesn't the moon have an iron core if its part of earth?
@@ReagonL0L As far as we know, the moon has a small iron and nickel core. This is according to research from the Côte d'Azur University and the Institute of Celestial Mechanics and Ephemeris Calculations (IMCCE) in France. Recent use of modern computing technology allowed French scientists to model the core using data brought back from the Apollo missions 50 years ago. The exciting thing is that even more discoveries about the moon will be made from old Apollo data due to better computing technologies in the future like AI and quantum computing.
Daz talking about all the stuff we send to space and the idea of stuff coming back... all I could think of was, "I hope we put enough postage on the stuff we're sending out!"
Just witty enough to keep you out of dad-joke territory😉 It was close though🤣
If you want to see the true effects of one of these there are great videos of the Chelyabinsk meteor (the second one shown here) that detonated at an altitude of about 20k with the force of 15-25 Hiroshima bombs. And despite an epicenter ~20 kilometers from the city, it still did millions in damage and injured over 1,000 people who were drawn to the windows by the flash of light in the daytime only to become victims of the shockwave. It was caught on a lot of dashcams and security videos, including the aftermath.
The smaller impacts are a lot more common than people realize. It is just that the Earth is big as hell & the vast majority of stuff goes unnoticed. For example, the last 90m impactor was just back in the early 20th century & had a yield of roughly 20 megaton. It leveled tens of millions of trees in the Siberian wilderness & hardly anyone ever noticed it.
As for how scientists understand the knock-on effects of this collisions, it isn't very difficult. The equations have been around for centuries at this point & thanks to the Cold War & modern computational modeling, we can generate very accurate models of what such impacts would entail. Not to mention that all of this stuff is heavily peer reviewed by every prestigious academic institution around the world. It is very hard to lie in the world of science & academia.
Very cool comparisons are made by this channel. It's cool that you guys are doing reactions from this. Thanks.
Last was 1908 Tunguska event Eastern Siberia. That last one is basically what end up forming our moon
Congrats on the 1 Million views you three!!! Quite an accomplishment for three Office Blokes! Cheers!!!
Imagine if you were in the International space station when something like that happen
One of the asteroid impacts shown said it was similar to the Chicxulub event, which was the asteroid that killed the dinosaurs and it impacted off the coast of the Gulf of Mexico. It was only 10 kilometres (6 miles) wide and it caused enough damage to wipe out the majority of the dinosaurs and that isn’t just due to the impact but also due to the dust and other factors like you guys suggested.
The NASA DART mission was a mission to slam a rocket into an asteroid to change its course, it succeeded in slightly altering its course and a slight alteration when it is very far away is all we need to save our planet.
Well fortunately, the way science works is that the scientist has to show their workings out regarding their findings. Asking other scientists to check their work. Other scientists (sometimes, many) either prove or disprove the findings.
In that sense, not only do others try to prove them wrong, they’re invited to do so.
I don’t know if anyone already addressed this but the frequency relates to how often an asteroid of that size crosses our planets orbital path, not necessarily how often earth is impacted. So if the frequency is 900 years then we would expect an asteroid that size to cross our orbit every 900 years with a low low chance of impact each time
Just Stop Oil: ❌
Just Stop Asteroid: ✅
Makes you realize that everything you've put into this earth could be wiped off in a split second. Wild
Lmfao 😂 “Boil an egg” that caught me off guard.
Neighbor: A moon is about to impact us in 5 min
Me: Stops recycling
For the first time ever a few months ago, NASA demonstrated the ability to move an asteroid.
The video by Veritasium about what we can do to prevent getting destroyed by asteroids is amazing.
A nice bit on the Ceres comparison : reason why they used 4 billion years as frequency is the last event we knew and see the result is the birth of our moon nearly 4.5 billions years ago when a sizable cosmic material had a collision with Earth and flung the parts of them both to orbit and had gravity pull it well enough to create a spehrical mass near the planet, hence the moon.
Man, you know the Earth is done for when the gregorian chants start to kick in.
I'm naming my kid Ceres
Tunguska meteor the first to hit ground, last hit of that kind was 1908. And giving the speed of spacerocks like this is between 40-70 kilometers per second you bet the blastwaves will be extremely superheated like pyroclastic flows on impact, yes indeed. Infact the animations here wasn't really correct since it also will eject alot of debree upwards on impact, like an upside-down funnel shape, throwing superheated materials more far away than the emidiate blast zone, starting fires way beyond the blastzone itself.
Another interesting natural fisaster video is the cascadia fault simulation.
My dad had a bad case of asteroids
You can get steroid creams for that.
Apophis is on its way here rn btw. 2047 it’s expected to reach us, and is also expected to hit us because it’s passing close enough that it could get caught in our gravitational field. That’s why they’ve been making rockets specifically for flying into asteroids, to change their course before they have chance to reach us.
Well, we live in a place that is still under construction. And it is also in the middle of a shooting range. Either we learn to protect ourselves before it's too late or we will regret it.
Definitely see the movie "Don't Look Up." Both very funny and terrifying. This comparison video severely understates the devastation. Anything above 100 m in the wrong place would easily end civilization as we know it and send us into Mad Max times. And once you get above1 km, it basically lights everything on the entire planet's surface on fire and the temperature all over the world goes above the boiling point for days. Then the dust in the air makes the world freeze for like a year. That's "extinction level."
There’s a few impact craters in Canada 🇨🇦
Look up the Tunguska event sometime. You may be surprised.
There is a decent size crater in Arizona that you can visit. It is about one mile wide. The crater in the ocean near Mexico is 20km deep.
Dave, Mike, Daz, Please send me that bumper sticker so I can spread it around Indiana
Those videos you see of the ones airbursting usually in Russia and cause damage and injure people are around 1m to about 7m and still can weigh hundreds to thoands of tons. The big one that happen In 2013 was around 20 meters and I believe weighted over 11,000 tons.
For years now they have been following the path of a few objects around 50 to 100 meters big, along with some known massive life altering ones that could make contact with the Earth from 2029 to 2040. Even if the big ones miss us, smaller ones or debris may still hit us and the "smaller" ones can still be 10 meters to 300 meters big. If they miss us the next "big" event shouldn't be until 2090s.
The last 50+ meter one happen in 1908 in Siberia, people claimed to have seen and felt the blast from over 300 miles away, there's also a lot of argument as to how often one this size will hit Earth. Some evidence and studies show every 100, others show every 300-500s others show every 1,000+, The problem is they have no idea how big the ones in the past were because of entry breakup. The one in Siberia could had been much larger but before it made impact it airbursted, they have no idea how much of it burned up in the blast, got thrown hundreds, thsoands, or tens of thousands of miles away, or how much of it went into the Earth for maybe miles
How tf do they calculate the frequency at 4 billion years. Like the earth is 8 billion years old and it happened twice? 😆
You guys know that NASA created DART project is for this very reason.
9:40 um, Daz....? the "shit" we send into space stays in near earth orbit and..... doesn't affect asteroids, comets, meteors, etc that are far, far, far, from earth.
and..... if they do happen to hit anything we've put into orbit before crashing into earth..... they'd go through the satellites, etc like shit through a goose.
"that would be nice" ummm no it wouldnt Mike.. I wonder if any of those are big enough to change the Earth orbit in any way where it would make more of an issue then just the destruction part of impact?
The human impact indeed. 14.4km (9 miles) crater diameter. Stock Exchange gone. All those businesses no longer around. Electrical fires just having to burn, because no way to put them out. Emergency services non-existent. Financial power gone. Basic medical supplies a luxury, even for the ultra-wealthy. Very quickly evaporating food/water supplies. Hospitals, prisons, schools - all gone.
Then the flash floods, earthquakes, constantly falling buildings.
Glad I live in faraway New Zealand. Kinda.
Seeing as I have an offshoot of our national faultline just 5-6 metres (at about 13-14km deep) from bedroom window.
Daz looking like he lost some weight 🍻
How maney dinosaurs where there on the planet before the astroid hit earth? There could have been other things that killed them off that was not so spectacular like lack of food, or them getting sick.
the third one hit tunguska siberia in 1908
What if this has happened b4 and we are the 10th iteration of life on the planet 😂.
dave, new intro is hard on the eyes
I'm just waiting for the epileptics to drop lawsuits.
yeah it's fucking trash. i always skip it.
well one good thing about that last big to hit new york is it would get rid of new jersey too , yea yea lol
You should some reactions on CMEs and EMPs
Trying to figure out why it says Tzar Bomb (5,000,000t) is only equal to 3.3 Hiroshima Bombs (15,000t). Am I reading this wrong?
It is 3333 times more powerfui. In America 1 thousand is written as 1.000, then add a comma for the decimal.
@Karle-Nathaniel Joakimsen Doh! I was reading it as ×3⅓. In the U.S. we do in fact use a comma to indicate 5,000 (5 thousand). I'm not sure which countries use a (.) Instead. For some reason I didn't recognize that all the numbers here were written with a (.) Instead of a (,). My eyes perceived the first 2 numbers were written as 5,000,000 and that only the last number was written as 3.333. Therefore I automatically assumed the period indicated a decimal point. Thank you for the explanation!
What the hell ben stokes is doing 😅
Please more disastrous earth destroying videos
The 90 meter one is similar to the tunguska event in Russia in 1908 the largest impact in recorded history.
That was the largest modern day recorded impact on Earth. The largest impact ever recorded was the Shoemaker-Levy 9 comet that slammed into Jupiter (July 16-22, 1994) and left scars literally the size of the Earth. Had it impacted Earth instead of Jupiter, well, there would be no Earth left.
@@gabriellareid3883 True but when i said recorded history i meant here on earth, but ofc u are right if shoemaker-levy hot earth ot would be absolutely devastating, but wouldnt necessary destroy all life on earth, but it would deciamte our numbers and set us back decades if not centuries before we could bounce back
Why is it always NYC? Leave my city alone. 😂
Tuguska was 1908. If it was 15 mintutes early instead of siberia it would have hit europe
That’s kinda why Musk wants a Mars colony. So that humanity could have a chance to survive something like this. By having people off planet at any given time.
The entire reaction: 🗿
No, not naked Daz and Dave! Gaynor already spilled the beans on the other channel about getting traumatized by a naked Daz bending over to pick up stuff in the bedroom.
I was picking up spilt beans 😂
8:04 I live in Toronto, pretty sure we’d be fucked too !
Enough with the million views , people tire of the groveling for views...roll the video.
damn could you turn the volume down on the video mate?
good reaction lads 👍
*1 million shmillion* ☕😫
Earth is about 4 and a half billion years old so we could expect the next big impact to happen in about 3 and a half billion years from now. One that potentially could be an Earth destroyer. I just hope for humans in the future that they have a plan for that if and when it happens.
Right now we have plans to influence & curve smaller asteroid trajectories using gravity bending with satellite tug drones & also using energy impacts to change orbits, such as NASA's DART project, but beyond that nothing much else, iirc. It not only depends on the size of the incoming object, but also its density & its velocity. Anything that's incoming way too fast is going to be difficult, as not only do we need to have spotted it very far away, but also the time we get a machine up to intercept. Then after that we cross our fingers. If it's bigger, then maybe we all pack our bags up for good, to the afterlife.
Don't worry. Humanity will be long gone until then probably. We have a big talent in fucking things up and destroying ourselves and everything else. By 2050 the population will be close to 10 billion as they say. That's 2,5 billion more than today. We have already problems with lack of water and food and big population migrations. Imagine 2,5 more billion to all this.. Eventually people are gonna start killing others for water, food and land. And that's just the near future. More fucked up stuff are gonna happen beyond that probably.
Earth is 4B years old. The moon was made by a glancing blow with earth.
Asteroids are not bombs. Period
Flat Earth spaceship.
Nothing can destroy New York City..... Nothing
We haven't sent up anything that could possibly change the trajectory of even the smallest ground-impactors. If you took everything we ever sent up, combined, we probably haven't enough mass to change the trajectory of anything capable of making a 500 m crater.
