Hey guys what's up it's Charlie here and today we're going to be looking at what
if we detonated every nuclear bomb at once I'm sure we all have a lot of
really burning questions for example what if gravity stopped all of a sudden
and what if we poured a glass of water onto the Sun well in this video we're
going to be answering those questions along with a bunch more if you want to
cure your brains curiosity then check out this video but first why not

I'm sure the most burning question on your mind is what if we detonated every
nuclear bomb at once well the answer to this question is it wouldn't be good you
see right now there's over 15,000 nukes on earth there are 4,500 cities on earth
and it would only take three nukes to destroy each one this means it would
only take 13,500 nukes to destroy every city on earth and this would also leave
at 1,500 extra nukes unused but most people don't really get the power of one
you let alone 15,000 well to put that into perspective that's around three
billion tons of TNT one ton of TNT is around the size of an average human
being so just imagine that times by 3 billion 15,000 nukes it's also 15 times
the energy of the crack at our volcano this was the worst volcanic eruption in
history but what if these 15,000 uc's all went off at the same time well these
nukes would basically make a fireball surrounding the entire world
the fireball would be around 50 kilometers across and it would wipe out
everything in a 3,000 kilometer radius believe it or not no matter where you
are in the world you would actually hear the explosion even if you aren't an
island in the middle of the ocean that you'd still hear it also there would be
a pressure wave circling the world for weeks that's right the pressure wave
would actually circle around the world meaning everyone would experience it at
different times not only that there would be the infamous mushroom cloud
that emerges after a nuke but instead of the relatively small mushroom cloud
we're used to seeing this one would stretch into space and the aliens flying
by would wonder why there's suddenly a mushroom sprouting out from earth not
only that if you live in South America then sorry but you'll likely be set on
fire that's because the nukes fireball would
spread to the Amazon rainforest very quickly this would then create the
largest fire known to man and it would burn down the entire continent of South
Africa and even if you weren't anywhere near the nuke chances are you won't make
it out of this alive that's because eventually the radiation
from these 15k nukes would wipe out everyone and everything the blast radius
would be hundreds of kilometres around that would make these areas inhabitable
and because weather and winds can actually accentuate radiation if this
means nowhere is safe perhaps a few government-owned secret
nucular bunkers would be okay but if the 15,000 Youk's went off near enough to
them they would also be wiped out too that's right even the world's most
powerful and wealthy can't escape if every nuke went off at once so now you
know why people freaked out so much when Kim jong-un threatens to send a nuke
over of course one nuke wouldn't be as bad but it would still be pretty bad but
all of the world's 15 thousand youths coming off at once would mean at the end
of the world now on to our next what if question what if gravity stopped all of
a sudden it seems crazy to think because gravity has been around forever
of course Isaac Newton realized the theory of gravity when an apple fell on
his head but gravity is what keeps us from floating off into outer space
well if gravity did suddenly stop then anything that's not actually attached to
earth would float away things like large buildings built into the earth would
probably remain intact but all humans and even small trees and animals would
all float into space but if the planet itself is actually held together by
gravity that means gradually chunks of earth
would float up into space and within a few hundred years most of the earth
wouldn't be on earth anymore instead it would be floating around
space with everything else this situation would also mean every human a
would be eliminated that's because every human and animal would be pulled into
outer space and of course there's no oxygen for us to breathe up there so
we'd all pass away the next question we have is what if we
poured a glass of water onto the Sun it seems silly pouring water on the hottest
thing in the universe but what would happen when the Sun actually go out
would it have any impact at all well I think it goes without saying that
nothing would happen if he poured a small glass of water onto the Sun but
what if we got a big enough glass that could hold enough water to put out the
Sun you have to remember the Sun is like a 2.5 billion square mile fire well
water only puts out fires because fire can't burn through the coating of water
but you have to remember there's no air in space and water cannot stop the
thermonuclear reactions that causes the Sun to burn in the first place so really
even if you had a water glass ten times the size of the Sun all of the water and
it would simply burn there's no limit to how much water you can pour on the Sun
it will just burn up and be eaten up by the Sun amazingly pouring all this water
on the Sun would actually make it burn even more the sound would be much much
brighter if we poured a ginormous glass of water on it that's because in water
there are vapors like hydrogen and oxygen that's because in water there's
hydrogen and oxygen atoms these would then be absorbed by the Sun hydrogen
actually helps thermonuclear reactions and adding oxygen to the Sun would make
a new star so pouring a giant glass of water on the Sun does not put it out
instead it makes the Sun burn even brighter and also makes a whole new Sun
the next what-if question on our list is what if the moon disappeared have you
ever wondered what purpose does the moon actually serve
obviously it lights up the night sky for us so we can see at night but would
anything else happen if the moon disappeared well the first thing we
would notice is our planet would begin to spin at double the normal speed this
would mean the Sun rotates around us much more quickly and it would cause
there to only be eight hours in a day instead of 24 this would also mean we'd
have around a thousand days in the year instead of 365 also if there was no moon
we would have a very dramatic climate change we would have very different
seasons and the world would get much more hot because we wouldn't have the
gravitational pull of the moon this would mean various things would happen
to the Earth's core this would cause things like earthquakes
and volcanoes on earth so next time you look up at the
moon and think what do you do you can remind yourself the world would be a
much worse place without the moon and finally the last what if question on our
list is what if the earth lost all oxygen for five seconds now oxygen is
obviously very important it's what plants produce through
photosynthesis to help humans breathe but would losing oxygen for just five
seconds really have such a big impact on the earth well try holding your breath
for five seconds if you are able to do that you'll see that losing oxygen is
not such a big deal for five seconds but that's only when it comes to breathing
what about all the other things that oxygen does for us
first off oxygen protects us from UV radiation this means if there was no
oxygen we'd all have terrible sunburns instantly also water is one third oxygen
everyone knows water is h2o so if there wasn't that oxygen in the water then all
of the water in the world would evaporate also if you live in a city
built out of concrete then say goodbye to it that's because oxygen binds
concrete and keeps it together if there was no oxygen in the world then all of
these concrete buildings would collapse also because oxygen makes particles to
scatter light this would mean the sky would be black that's right we'd have a
24/7 night sky so even if we lost all oxygen for five seconds and then it came
back the world would still end that's because all of our buildings would be
destroyed and all of our water would be dried up not only that we'd all have
terrible sunburns and BP recovering from a very scary black sky so guys those
were the most burning what-if questions I'm sure you wanted to know the answers
to if you guys have any more what if questions you've always wondered about
then comment them down below I'll try to do some research and find out what would
happen for your what-if questions but in the meantime check out the poll in the
top right corner and you can check out the most amazing what-if question on
