so we're trying out a new channel today it's called riddle looks like it has some
uh interesting videos but if i look a little tired today i'm a little bit sleep deprived but anyway
before we get into it just editing this video and before i put it up i wanted to add that i'm going
to create a member area for the youtube channel so i'm going to put up videos only for members
and so it's a bit like patreon you pay like one or two dollars each month you get access to these
member-only videos and i can react to anything because i don't have to abide by copyright
with these private videos because i want to turn monetization so no ads and we can watch anything
but it's normally a car like i don't want to get copyright strikes and things like that
so whatever you guys request i'll be able to watch you come sign up for the daily dance newsletter
which is a separate thing breaking down the latest news in stem over the last 24 hours in a nice
quick easy format should come get the free email and then i'm also creating a post quantum vpn
which is gonna be like the first of its kind available to you guys we have this free alpha
about to come out uh and we're gonna do some testing so if you wanna use a vpn for free
um you should come sign up to get notified when it comes what if a media hits the earth at the speed
of light alright so this is impossible but let's just pretend like you know it can happen well i
can actually already tell you what would happen and depending on how much physics you know i mean
this question would be absurd to you but also depending on how much physics you know uh would
you might might determine how surprised you are by my answer oh yeah i'm not gonna tell
you right now because otherwise you're just gonna leave and i don't want you to leave so i'll tell
you at the end of the video more than four billion space bodies aka meteoroids fall into the earth's
gravity well every day this moniker covers everything in size greater than interplanetary
dust but less than that of an asteroid these are small stones in the majority which quickly burn up
in the terrestrial atmosphere only a few can pass this barrier meteoroids that reach the earth's
surface are then called meteorites at the same time they do not pose a particular danger although
occasionally they can make local residents nervous as happened recently in chelyabinsk but what if
we increase the velocity of the meteorite to the speed of light if you've never heard of this chili
oil once i can't pronounce it so that asteroid was like 17 meters 56 feet in diameter and weighed
something like 10 000 tons metric tons right um so it struck earth's atmosphere uh at like 40
000 miles per hour which is 64 000 uh kilometers per hour which is like 17 kilometers per second
so the explosion was something like 30 to 40 times stronger than the atomic bomb uh the us
dropped on hiroshima so it was very serious you might have actually heard of the tunguska media
which was another object that exploded over siberia in like 1908 and uh that actually
had uh much more uh energy in that explosion it flattened something like 2 000 square kilometers
of forest that's pretty serious no particle with mass is actually capable of the speed of light
but in fact for our purposes we don't need it it will be enough simply to approach this speed
just a little such that the entire solar system will be in shock okay well it's a little bit uh
you know clickbaity then isn't it if the title is at the speed of light but we're like no we're just
gonna let's do this in the proper order anyway imagine that we have a round diamond ball 30
meters in diameter and we have just launched it in the it really doesn't need to be made out of
diamond when you approach the speed of light like that won't matter at all uh and i can see it says
3 000 kilometers a second that's uh nowhere near the speed of light so you know the speed of light
is 300 000 kilometers per second so that's one percent the speed of light which is still very
fast don't get me wrong like to give you some relative motions the fastest comet we've ever seen
in our uh solar system is something like 48 moving at 48 kilometers per second so you can see from
this that's much quicker and comets move about three times faster than asteroids so if a comet
was to hit us it would be actually worse um well depending on how fast it's moving right and that's
generally because they come from further out so 3000 kilometers per second is fast wha what's some
other relative motion the sun is moving around the galaxy at about 220 kilometers per second
and then our galaxy itself the milky way is actually you know relative to the cosmic microwave
background radiation is moving through space at about uh 620 kilometers per second so obviously
3 000 kilometers per second is very quick that the air in our atmosphere began just launched it
in the direction of the earth at a speed of 3 000 kilometers a second first of all it should
be noted that the air in our atmosphere begins to participate in nuclear fusion at such velocities
and with this plasma heating the pen process might be able to destroy our diamond sphere entirely
before it reached the earth's surface but the earth will not get the better of us this sphere
will not fly wide enough and at some point will crash into the earth a thousand times more energy
will be released during the impact than from the most powerful nuclear weapons of all time and
at the same time the entire this is boring it's only .01 of the speed of light the crater will
be huge this heat will cause stone to be dispersed at 0.99 relativistic effects are beginning to act
links that hold the sphere as a single entity completely fail a diamond meteorite becomes
just a bunch of carbon atoms moving so fast that a lorentz contraction flattens the sphere into a
pancake we would of course not be able to notice this visually each carbon atom in the sphere
carries about 70 billion electron volts of energy they're moving too fast to collide with the air
directly and simply pass through it molecules of air penetrate through three meters of the sphere
and then get stuck inside it expands rapidly and reaches the earth with a greater content of matter
than at the beginning of its fall when it hits the surface it disintegrates completely rending
the earth generating a deep and wide cavity and creating a cone-shaped channel through the earth's
lithosphere the energy of the collision will crack a hole in the earth's crust and knock out so large
a crater that through it you should see the molten mantle the collision will release energy similar
to 50 times that of the cheeks along asteroid this is enough to cause a mass extinction on the planet
if not the end of all life in general would you like to witness such a grand performance
i'd rather not it's boring let's add another few nines 99999 the speed of light now
each carbon molecule carries 25 trillion electron volts of energy which is comparable to particles
in the beam of the large hadron collider under these conditions all of this will hit the earth
with roughly the kinetic energy of the moon moving in orbit this is enough to punch a tremendous
and to disturb the earth's surface so much that it melts completely this with even greater
probability will put an end to all light let's add just a few more nines 0.9999 999 999 99999
the speed of the fastest object that has a mass which has been observed by mankind
will be obtained the oh my god particle as it is colloquially known but let's not blame god
for this the oh my god particle is a proton from space which plowed into the atmosphere
over utah in 1991 and it was moving at almost the speed of light 99 point followed by 21 9 5 1
the speed of light the cascade of particles that were formed from its collision could not even be
reproduced in the large hadron collider a similar phenomenon is detected several times a year and
nobody understands how exactly they are produced it seems that they come from the general direction
of the explosion of galaxies but what happened there to make them leave in such a hurry and why
didn't they slow down before they got here the omg particle is really cool i don't think we've ever
talked about it on this channel so just a few fun things it basically had the same amount of kinetic
energy as like a decently thrown baseball right but it was compressed down into you know an object
the size of a proton so that basically means you know this thing had 10 million times more energy
than you know our most powerful particle collider the lhc can even produce and you know due to
relativistic time dilation at that speed drop this particle could travel to our nearest start uh
proxima centauri right in like 0.43 milliseconds in the particles time and in the time we've been
talking about this thing it could have traveled to our galactic core you know in its own time
and you know since we've seen this thing we've been looking out for them and we've seen like 100
since you know these omg class particles we still don't know what it is it could be weird gamma
ray bursts could be something more exotic like topological defects from you know the very early
stages of the big bang could be weird interactions within dark matter maybe we're getting physics
wrong and you know our distance limit calculations just a little bit off maybe maybe maybe right we
just don't know scientists and give our diamond ball the velocity of the oh my god particle now
this thing will be flying so fast that no modern computer technology can simulate such a situation
we can't simulate any of the like even traveling at slower speeds with any accuracy because the
simulations you know it's not like we have all the particles in the signal like i just have so much
so many problems with what he just said simulations our best current simulations
are not that accurate because you know like the computational complexity of putting
you know what's going on in reality in a computer we're not there yet and we're nowhere near it
um so that statement i have a big problem with it particle motion is extremely
complex because there's so much so many particles and it's such a complex behavior
we have this we just cannot simulate it but anyway or we cannot know for sure how everything will
turn out but we can roughly outline we actually can know for sure what would happen in this
situation as i've already told you but again this just isn't possible so don't worry about
it in general terms our diamond ball sweeps through the atmosphere not even noticing it
and disappears into the earth's crust a cloud of expanding plasma with accompanying radiation
diverges from the entry point while energy pulsates outward through the body of the planet
40 milliseconds later the entire far side of the planet is expanding outward in the form of a
glowing cloud the diamond meteorite and cascade of particles which it created in its collision with
the earth's crust spreads outward through the body of the planet the planet starts to glow brighter
than the sun from overheating there will be such an impact so as to knock the earth into another
orbit but it doesn't matter the earth is no more the precipitated energy is 10 000 times greater
than the energy of the planet's gravitational bonds therefore the earth explodes in the form of
an expanding plasma cloud and especially energetic flows will jet into space in the direction of the
impact the sun almost chokes on the waves of dust that envelope it and the surfaces of the nearest
planets are clean to brilliance by the incredible high energy plasma shock wave that's fireworks for
you you watch to the end okay i think it's time to actually tell you what would happen
so it's actually very obvious so uh if if you had something that had mass uh you know traveling at
the speed of light that would actually take an infinite amount of energy that's why you can't
do it okay it's impossible for anything with mass to travel at the speed of light so what
do you think happens if you have something that's moving with an infinite amount of energy when it
hits something else like just what do you think yes that's right everything is destroyed like
the thing itself and earth and just completely be destroyed not only that if now you go to the
speed of light go to infinity well you're probably going to destroy the universe itself you're for
sure going to create a black hole you're probably going to create another universe
yeah so this is just an absurd question hope you enjoyed the video i'll catch you next time
