8:45 I am actually from Chelyabinsk, the city the meteor hit, and it was in 2013, not 2015 The fireball emerged in the morning sky around 9 am and we could see it before we could hear it, because it glowed brighter than the morning sky. After some time around 30 seconds to a minute, can’t remember exactly it blew up. That’s when we heard it, the explosion and the shockwave was so strong it shattered windows all over my region, and around 1000 people got injured in the aftermath, mostly from glass. It was pretty scary, at first we thought it was a nuclear missile, then we realized it was a meteor. Funny thing is, there was another asteroid that was supposed to fly by the earth later that day, NASA was actually tracking that one, and everyone in my town thought it was gonna hit too, so we pretty much expected the apocalypse that day😬

Trouble is, long period comets are 1) far away and not detectable until they're on their way in; 2) really big; 3) falling in toward the sun (and, potentially, us) from great distances and therefore really moving by the time they're here. The risks of long period comets are small but very real.

If all she saw were the main clips of the films (which may make sense, how much time does she have to watch the what...10 movies or more featured?) then all she would be going off of is the clips. Tyson and other astrophysicists may be going off of the full film(s), thus Deep Impact is rated not just for the impact scene (which may have Hollywood flourishes) but also the lead-up to the impact and attempts to knock it off course. I do find it hilarious that they have serious experts like these actually rate the 'science' of cartoons like Ice Age - like what do you expect, they are janky kids movies with some subtle adult humor, not documentaries.

All we see is a chunk of city that has been ejected into space, presumably right from the impact point. Now is that realistic? No, the chunk wouldn't be intact, it would just be rocks.

And while it's technically correct, it's not even a quarter of the whole thing, if it was exclusively friction, the rock would heat up to 300-400 degrees Celsius at most. The material wouldn't even glow. What actually causes the "fireball" is adiabatic heating. Basically: 1) the rock falls into the atmosphere very, very fast -blasting "if you smell what the rock is cooking" at full volume- 2) the air on its way gets compressed very, very rapidly (it's squashed before it has time to spread to the sides) 3) temperature of the compressed gas increases greatly because thermodynamics says so, manshaming the puny friction heating 4) the air gets so hot it ionizes creating the fireball What it means is that the rock itself gets even less heated up.

This story is WAY out of her comfort zone and if she knew anything about Lovecraft's mythos, she wouldn't have even dared to bother critiquing the movie. Lovecraft wrote stories about things that were supposed to be completely unknown to us. As you have said, this could literally just be summed up as a "magical rock". A very DANGEROUS "magical rock".

A key point to bring up is that the rock is NOT "magic" the "Colours" or lights are/is actual aliens. I know it's a hard concept to grasp, thats one of the fascinating aspects of the story, for those that have not read the story please do you can read it for free online or find audio readings on YT both in any number of versions and places. While there have been a couple of good movies based off the story (namely the Cage 2019 movie) made they ultimately can't do it complete justice.

She says: _"The size of that thing is not a meteor. Those are big rocks, and we now know that meteors are really tiny small specks of dust. So meteors are different from asteroids and comets and meteorites."_ This is utter nonsense. A "meteor" is any piece of natural debris that's falling through the atmosphere. Of any size. A meteoroid is a small rocky or metallic body in outer space. (They become meteors if they fall into a planet's atmosphere.) A meteorite is a piece of meteor that has fallen to the ground, surviving its atmospheric entry and ground impact. A bolide is not a "super-scientific" term. It's an informal term used to describe extremely bright meteors. There's no exact definition.

A guy jumping 50 meters in a bubbling pool of 1200C lava would literally explode i think.

Was a bit surprised she said we'd see it before it got to that point with Armageddon because in the movie they did identify it a few weeks before it got that close. Guessing she didn't watch the movie, lol. Also the scientists have said if one comes from the direction of the sun we'll be completely blind to it until it's too late given that most of the ways of seeing it would be blinded, so it's not entirely farfetched. There have been several "close calls" where NASA didn't even see the asteroids until it was too late or they were already passing because they came out of the blind spot. She mentions the same thing when talking about Deep Impact about how we wouldn't know only if we didn't track it, just odd she ignores that there can be rogue asteroids we don't see. I won't even get into the part where she says you'll hear it before you see it, lol.

This series is good and informative.

Very interesting! I have always wanted to see a meteor and I finally did! It was about a year ago now, high in the air, green turning to orange. I reported it on a website that tracks such sightings and with 500 or so reports, they estimated it at about 450 miles south of where I saw it at high altitude (don't remember exactly, maybe 40,000ft?) Anyway cool video - thanks!

With everything thats happening in the world i asked myself "do i really wanna watch this, and lose another nights sleep"...well i did and now that i heard her say "dont be afraid" i actually have one less thing to worry about 😆

I think a nuke buried inside an asteroid at a carefully chosen depth could actually be pretty effective at deflecting or obliterating it. Especially if it's a rubble pile. Look how effective DART was? The amount of material ejected far exceeds the momentum of the actual impact.

The Tsar Bomba was designed for and capable of a 100+ megaton yield. Russia added numerous compression stages and a lead tamper in order to reduce fallout and to allow the plane that dropped it to reach a safe distance before detonation. Fun fact: Seismographs were still picking up reading from the explosion after the shockwaves had circumnavigated the earth 3 times and the blast wave shattered windows as far away as Norway and the mushroom cloud almost hit the Karman Line (the accepted distance where "outer space" starts).

I disagree with her that the guy in the Expanse clip would hear it before seeing the light. Light travels more or less instantly on that scale, where as sound travels a comparatively slow 343m/s. When the Chelyabinsk impactor hit Russia, the shockwave hit whiteness anywhere from tens of seconds, to several minutes after the impact.

You are right but u r also wrong. Listen to her whole sentence. And I can relate to hearing sounds before we see the object or light. Um... Suppose aeroplanes, if they are at very high altitude you hear them coming first before you see them and that is when they are actually above you. The sound keeps travelling in all directions while light may or may not appear to you at the same time depending upon the position of the viewer and the source. Generally, we compare lightning and thunder to explain why light travels faster then sound but the deal is that lightning are pretty straightforward and they are happening inside our atmosphere most probably in front of us. There are also instances where we do hear the sound of thunder and don't see the lightning. So, I am not calling you wrong you are right but I am also telling that she is also right.

The light from a super bolide, large enough to reach the ground with a significant fraction of it's cosmic velocity, is going to be ridiculously bright. It's just not something you wouldn't immediately notice. Even with your eyes closed and your hands covering your face.The one featured in this clip looks to be at least as large, if not larger that the 1908 Tunguska event. When that entered the atmosphere, it appeared as bright as the sun to whiteness 65km/40mi away. Even more intense than the visible light, was the infra-red radiation. Those same whitenesses described it as feeling like their skin was on fire. The blast/sound from that impact took another three minutes to travel the 65km to those whitenesses. Not only would an individual see the light instantaneously, but they would feel it instantaneously too. In your airplane analogy, an aircraft is visually insignificant. A small dot in the sky, so it's very easy not to notice it before the sound alerts you to it's presence. Same with lightning. If it's some distance away, or during daylight, it's easy to not notice it before thunder. A super bolide, like the one in Expanse, is on a whole other magnitude. If your out in the open, like this guy is, and close enough to be killed by it, then the light is going to be similar to that produced by an atomic blast. There's just no scenario where someone killed by the blast outdoors, wouldn't immediately notice the light, with the sound/blast/death coming tens of seconds, to minutes later.

To be fair on the Greenland damage for the stuff around the world, on the pull out image of Earth, it's shown to have been hit by a ton of also big asteroid impacts in addition to the big one. 16:18 Also strange that they think people would have oxygen to somehow scream or even live at that point.

But they weren't trying to blow Dotty up, they were trying to blow it apart... They rather said what she said about the quantity of nukes needed: "Given her size, composition, her sheer velocity, (slight laugh) you could fire every nuke you've got, and she'd just smile at you and keep on coming."

Yeah wasn't the premise to break the Asteroid into smaller pieces to minimize damage rather than completely prevent impact?

Due to the last comment (about size and Earth's destruction), I would have liked to hear her view about Melancholia's ending since it is the largest object hitting Earth I've seen in a movie.

Good entertainment for us movie goers and good education on what if we see a real impact of a Comit or an asteroid.

05:48 I'm surprised she thinks someone would hear it before seeing it in the sky. Light travels WAY faster than sound. I remember the meteor flying over Russia. Lots of people saw that light way before the sound/shockwave came into play. Expert, you say?

Hey Insider - could you please start adding the titles of the movies at the "rating card" screens? (or if you don't want it on the same frame, have the title just before (maybe morph to the ratings text?)) It is a bit annoying having to scroll back and find the brief title inset if there is a movie that seems interesting.

Interresting! Forgot Impact (2009) with Natasha Henstridge. Wondering about brown dwarf impact and it's effects.

You've got to love scientists when they say don't be worried we're looking out for anything... If they do find something big enough... They can't do anything 🤦‍♂️🙃

we could still determine the damage level, what areas will be impacted, literally and elsewise, and where the safest places would be. All this could save just enough of us, even if we can't stop it in the first place.

She is not an expert... Thermal radiation 500km away would take a minute to reach him? Are you fk kidding me? What is thermal radiation? Light for the love of God... LIGHT. Near instant!!!! She said a minute, while it would take...1/600s Also... You she would be surprised if he did not hear it before seeing the light? What is faster... Sound... or a god damn light... Light... a million times. Asteroid expert is she ? OMFG..

5:51 you definitely would not hear it, the speed of sound is slower then light, so you see it first.

You would see it, then you'd notice yourself turned to ash, and then several minutes later, you'd hear it with your ash ears. Obviously, the residents of Nagasaki didn't go deaf before they were melted.

I love these videos for the insights in all kinds of topics, but I hate how quiet they are in comparison to practically everything else I watch on youtube.

Thank you to the expert for doing the job they do.

The Great Daylight Fireball of 1972 skipped off the atmosphere, entering over Utah and leaving over Alberta. The thing was, it came low enough to create a fireball, but high enough not to lose too much kinetic energy, about 57 km. I would expect a mile-wide asteroid passing at that altitude would likewqise escape.

A mile wide asteroid would probably have too much gravity and be pulled apart in the same situation

I actually saw a meteorite impact outside of McMinnville, Oregon in 2004 or 2005. It was immediately obvious what it was; just streaked down in a shadowy line and went in to the field; no puff, no thud, nothing. I was like: Huh.

She is a tough critic, which makes sense because science. However in the first half of the video she rates mostly on the visuals of the fireball and the trail, but in the second half she rates mostly the impact itself and the result. Deep Impact seemed to be realistic regarding the trail, the dust and the resulting shockwave... And about it. Maybe better than 1/10?

"You need atmosphere to have sound". that totally makes sense but it's not something I have thought about. Great point lol.

Correct me if I'm wrong, but in Armageddon weren't they SPLITTING the asteroid, not blowing it to pieces? Seems to me that would take much less force if you knew what you were doing...

"Generally meteorits are not spaceships" lol. Love it!

Her saying you would hear the meteor before the flash told me everything I needed to know about this “expert”

Being honest, I think the scientist had a few things wrong on what would happen. Let's see my layman opinion: Armageddon: First, yes asteroids and meteors CAN be missed, even ones this size, depending on where it begins to come to Earth. It's not unrealistic that a 1000km asteroid can be completely missed if it comes from a path where it doesn't reflect light, as we saw with Asteroid 2021 UA1. Even now, we have THREE planet killers that we only recently detected because they were masked by the glare of the sun. Also, while I will concur the magnitude of the explosion would need to be a lot higher than the one nuke they used, the physics of digging a hole and putting a nuke inside a hunk of mostly rock is sound, and was explained in the movie with the adage of a firecracker in your hand blowing your hand apart. Rating - 3/10. The Good Dinosaur: Yes rocks in the Asteroid belt are not neat and tightly packed, I wholeheartedly agree. Can a lump of rock 1.5 miles wide skim the atmosphere? Yes it can and has happened, again referring to Asteroid 2021 UA1, which flew by 3000km (Earth's atmosphere is 10000km). I'd say that's "skimming the atmosphere." Rating - 2/10, primarily for the belt depiction. Expanse: Was it a good hit? Yes. What was wrong? The wave caused from a water impact. Waves have a tendency to draw their water from somewhere, similar to another movie reviewed here, and real life events. A sudden disruption of the ocean, as was seen here, would have had a sudden pull-back of the beach exposing 100s of meters of land before the hit. Kudos on the heat/radiation, but the fact I did not see the water recede at all makes it a bit unrealistic. Rating - 4/10. Greenland: Ahh, one of my fave current asteroid/meteor/comet movies. Is it realistic? It's a mix, and yes it's normal to see "splinters" or meteors coming towards Earth along with a comet. Remember, the universe is one huge pachinko machine, with tons of rocks scraping, hitting, splitting, and yes, changing trajectories all the time. Is it possible maybe this comet disturbed and transferred energy and speed to more than a few chucks of rock when it began its trajectory? Yes. Having a comet come towards us at saying... 10k meters/sec (future ref mps) would be fast enough to skim and hit any asteroids, and send smaller hunks of rock at a similar pace, similar to how a bullet travelling at 800 mps would also send fragments of rock in about or slightly less speed, only little to no atmosphere. Now, the comet in the movie was about 15 km, half the size of the Chicxulub meteor was double that size, so Greenland wouldn't be an ELE. The destruction was quite realistic for a civilization ending event, but yes, the cloud cover would have been darker. Rating - 4/10. Bruce Almighty: Low-hanging fruit. Quite unrealistic. Rating - 0/10. Ice Age: Ok, this "expert" needs to be briefed on the difference between asteroid, meteor, meteoroid, and meteorite, plus learn what a "meteor shower" is. Yes, there is a thing called a "meteor shower," when a cluster of meteoroids crash into Earth, and is a commonly respected term used by many scientists. Size doesn't matter on meteors, meteorites, or meteoroids, it's when it comes into contact with our atmosphere does the term change. That being said, a METEORITE coming at you can easily be a death sentence, especially at that size. Rating - 0/10. Color out of Space: Yes, a meteoroid. One thing gotten wrong is while the inside might be frozen, the outer cover would be hundreds, if not thousands of degrees hot thanks to heat and friction with our atmosphere, and while the rock might not burn, anything combustible that it hits (yes even dirt has a combustion temperature) would smoke and possibly burn. That being said, I'd say the impact crater was nowhere near the magnitude of a lump that size, but as the core temp rises (be it from the outside temperature, or just surface temp spreading out), anything inside could come back to life and wreck havoc. Still, not the best example. Rating - 1/10. Deep Impact: At the time, the science of a theoretical event was very sound. The tsunami was approximately 400 meters high, traveling about 492 mps. Hitting the towns it did is VERY likely even with a tsunami at 1km traveling a bit slower, as most of the towns were barely above sea level. A 1km high tsunami traveling 200mps would possibly travel 10km inland, depending on the land it hits. The 2011 tsunami was 40m high, and traveled 700 km/h (195 mps). The tsunami was grand in scale, but the science was more sound than most of the other movies where a fast object hit a major body of water. Rating - 5/10. Don't Look Up: Fantastic drama, horrible science. Agreed, the size and speed of a lump of rock to hit the earth and split it apart would need to be orders of magnitude bigger than the movie. Rating - 1/10 only for how they figure out the asteroid is coming towards us.

I was watching a meteor shower with my son and we happened to be looking at a spot where a point began glowing brighter and brighter white, then it faded. It was a meteor that was pointed directly at us. I'd never seen that before and I've seen some amazing meteor showers. That was super cool! We joked that it would've been funny if the glow subsided and a few seconds later we went a "doink" on our head 😂

I think you mean an asteroid shower. She'd know. She's an expert in what an asteroid is, and there's no other sort of space rock but asteroid. :)

To be fair about the purple rock, in the context of the film nothing about that rocks existence was supposed to be “normal”

2:10. So does them detonating it on a fault line that runs all the way through it change this at all? I believe they theorized that it would fracture it along the line and split it in half.

Great host I learned a lot. Can say I’m less afraid of asteroids than I was before lol
