welcome back my friends my name is Dylan I just put a PhD in physics on hold to create some fun
things one of those things my AR project am I interior.com is out now and you can use it
for free don't need a credit card just take a picture of your room you upload it to my site
and you can turn it into any interior design style in literally 30 seconds so come renovate
your whole house come have some fun hey my cars is also about to drop asteroid impact comparison
let's do it so of course we'll talk about that big asteroid that wiped out the dinosaurs you know
technically it was the highest ratio of killing birds to one stone in Earth's history fun model
okay thank you
this video we use Hiroshima and zaboma as the unit of measure for destructive power that's
pretty cool especially after the videos we've just been making so we're pausing the nuclear uh we're
Paul's in the Oppenheimer celebration week uh for these last two and then we'll get back to
every once in every 70 years I see energy air burst 18 Heroes explosion height 21 kilometers
wow this is a great video
next impact 50 meters it's pretty big once every 900 years 388 Heroes 7.5
kilometers we can make a bomb that big easily bacteria New York City
it's plenty of hydrogen bombs with twice this field damn that did some that did some damage
so that one made it to the ground yeah the tongaska event is a pretty cool event one
every four and a half thousand years is that correct how many Heroes 208 so NASA actually
just told everyone a couple weeks ago to not make any plans on our Valentine's Day 2046
because a newly discovered asteroid might just hit us don't worry though it's like one in I think 560
chance that it does so yeah don't worry about it it's 50 meters by the way so that's that's
pretty big right one kilometer is a is a world killer Planet Killer but I mean just gave him
my 23 years is a lot of time for it to change its course and increase the chances of it hitting us
also keep in mind guys this depends on how fast these things are moving obviously like that is
a one of the major components here it doesn't just matter how big it is it matters how fast
it's moving I wasn't paying too much attention at the start uh did they say that every asteroid
is moving at the same speed because their velocity is going to be really important for
how much energy is going to be you know go boom all right that's entirely a major component here
um and on average in asteroids traveling at about 17 kilometers every second
that's [ __ ] fast so I mean did I miss it where are we at 213 uh
uh no I guess they're just taking the average of this one that would
happen every okay so that must be what they're doing Eddie boom
begin creators now you wonder why the creators are always round like this and they're not like
um you know displaced and there's like kind of slides right you'd expect an oval it's because
when they hit the ground they just explode because there's more energy there's more kinetic energy
than the chemical energy holding it together so when it hits something you go kind of like when
you throw a snowball at a wall right there's not much chemical energy and stuff holding it together
when you throw it's got more kinetic energy and so that energy has to go somewhere and it
goes bang the snowball explodes and if you throw a snowball at the wall in front of you it'll leave
a round imprint you throw a snowball at the wall on an angle still leaves a round imprint because
it explodes that's why all the creators on the moon around you never thought about that so many
creators on the moon they're all [ __ ] around it's like what the hell is going on why aren't
they aren't ovals and for a long time scientists thought they were this these creators were
actually from volcanic activity but but no we then saw Schumacher Levy hit Jupiter's atmosphere and
just exploded we're like what's going on there we realized all right that make this makes a bit more
sense and just think about how old the Moon is we've never seen anything like hit it and go boom
but actually we have there was uh I think uh a couple priests way back like a thousand years
ago and they documented it in their notebook or something they didn't want to tell anyone
because they were kind of scared them but this one priest apparently saw an explosion on the moon
that thought you know the end of times is no
[Music]
370 meters Apophis all right so Neil deGrasse Tyson has sounded the alarm on this one for a
fair while because as you would come back around in the 2030s at some point I think it's like 2038
20 to 39 or something um it's not gonna hit us there's a very low chance it's gonna hit us don't
worry but anyway so this happens once every 97 000 years 51s our bombs okay so we get that's
a lot of energy because one's our bomb is about 50 megatons TNT so that's two and a half thousand
Megaton TNT hello Dandy I want to sing the AC DC song DNT but we'll go copyrighted to a car
Legend okay that's that's not good your daddy fly
just an FYI they only need to be over a kilometer to be considered a planet
killer and if you didn't know just last year end of last year we uh discovered one of these
bastards just floating around so it's in the top there's 1.1 kilometers about that and
um you know it's in the top five percent of you know sizes we've discovered of these things and
uh yeah if it hit the planet it would not be good it would blow up so much pollutants into
the atmosphere that you know it would we would be there'd be mass extinction events and it would be
horrific and there'd be less sunlight getting down to the Earth's surface and all sorts of wonderful
things Earth would cool significantly currently it's crossing our path though when we're on
the opposite side of the Sun but over time this thing is going to start across our orbit closer
to where we are and uh it could be a problem in some centuries uh but I'm sure we'll be able to
deal with it that's not good at all all right let's hope this ain't gonna happen anytime soon
[Music] I think the destruction would actually be significantly worse um
silly things in it that you know just break science create a 14 kilometers like when they're
they send these um Drillers these oil drillers to the Moon to drill not the moon to this our [ __ ]
asteroid to drill down in the asteroid and put a big bomb in there and so they think it's going to
be easier to train the Drillers to be astronauts than to train astronauts to drill a hole
and then they're up there in space in these shuttles flying around as
if there's [ __ ] air and they're going like
it's pretty funny makes her a great but it's a great movie all right Bruce Willis Ben Affleck
that song that I also can't sing once every 500 million years we're up to the great bird killer
yep 65 million years ago and we're Jew again so uh we also recently discovered guys if you
didn't see that uh it looks like it had a little twin had a buddy that uh there was
it looks like there was two uh right and one closely uh followed the impact of this thing
which is really interesting and then uh let's see how they visualize this because
000 near Earth objects now and that's Rising like we've discovered most of those in the last decade
awesome that's so cool so there's some current hypotheses say suggesting that um before this
thing even hit the surface that it might have actually to some degree bubbled the crust
to the point where you know the magma was already rising up at the crust before it even hit
which is just insane uh and if you see here right like there's no sort of shock wave
that's sent out uh wait has it hit already no no good they did see how there's a shock wave
that that spread out I missed that right it goes it hasn't even hit the ground yet this
is good stuff and it might have been more severe at the the surface before it hit
that there was a magazine Army possibly uh we'll just set on its way from the
dino killing asteroid and a simulation actually shot that had hit Australia
next impact all right 20 kilometers how many how
watch the news don't worry I mean like science news literally the end of the Feb we just found
this uh asteroid that's going to pass in between Earth and the moon and they're calling a once in
a decade event but if you look at astronomy news that we constantly find asteroids and we
only just saw this thing that's the whole point right we constantly do this where it's like hey
there there goes something again and we you know Discover it after it's gone by and it like you
know doesn't it's not that far away right it's like between Earth and the moon sometimes just
beyond the moon Moon's only 350 000 kilometers away all right and we only just discovered
these things Time After Time so I don't know you know are we gonna get unlucky soon and something
slams us potentially I don't think we'll miss anything big enough to sort of do um you know
end civilization but I think there'll be events like the tungaska event again maybe even soon
it's very likely it'll just hit the ocean though because uh you know this place is mostly water
100 kilometers all right this is a world killer right once every four billion years all right
it's important to say here as well I've said in other videos that all of these things right if
you go back to the early uh you know early time in Earth Earth early history you know
during the heavy bombardment and late bomba all these things right there was way more debris we
got hit so much more often all the time there were Dino killing asteroids hitting us every I think it
was every 15 million years or no was it every 15 000 years like just getting smashed all right so
thousands of albums hang on a second impact energy didn't that wasn't the last one eight
million seven hundred thousands our bombs what's going on let me check 450 yeah what the hell
in mind guys you get what I'm saying like it's it's so this one actually there's
some interesting stuff behind this because if you've heard of the early impact hypothesis
this is what this is referring to all right in Earth's early history it's there's a hypothesis
that Earth was hit by a mars-sized moon or planet right and it just went bang and what
was that resulted in uh the Moon the Moon was what was left that's one of it's actually the leading
theory hypothesis for how the moon was formed if you're wondering how the hell we know this right
there's actually some evidence if you go look at the Moon uh we know that it was molten down
um you know for some reason at this sort of time and to to do that it would require enough energy
you know that the similar amount of energy that would be sort of created
if that event what we just said happened so that's why we suspect it didn't happen
I love the the music for this one
it's a big boy
[Music]
oh kaboom
yeah that ain't good
thank you
this is roasters
awesome video really good video but there's another thing now you might think oh asteroids
you know they're not that cool they're not that important but did you know that life on Earth
may have been seeded by asteroids so they might be really important this this comes from these ideas
called panspermia natural panspermia artificial panspermia like in the movie Prometheus where
a planet is seeded for Life uh but basically asteroids might be carrying around like amino
acids and just other weird things right that uh starts life when they crash into it and they they
carry water around which is also very necessary for um you know life you know we may discover
when Elon gets over to Mars that uh there used to be life there and what happens if it was if
we discovered a lot that life was on Mars first that it's actually older predates us well some
people might suggest then this means that out of natural panspermuse might be correct where you
know an asteroid could have hit Mars when life was there earlier than Earth's and it you know
transported that life to Earth you might have heard of uh water bears those little you know
things that can survive any sort of conditions not anything but you know like they can survive
the vacuum spacefully 30 days um so who knows make sure you leave a comment down under let
me know what you guys want me to watch come check out our interior.com I'll see you guys next time
