we're gonna go there and talk about theoretical physics well then I'm going to say well maybe
that's not the limit maybe saitama could be even more powerful maybe he could destroy
them if you're new around here my name is Dylan I just put a PhD in physics on hold to create some
fun things and AI my cars is now out you just take a picture of your car you Chuck it in my
website and you can turn it into a Supercar muscle car it's a lot of fun so come check
it out anywho let's get into this video I am so Keen for the new uh one punch man season later
this year some of my very favorite episodes to do come straight from you guys follow me
on Twitter so suggest what episodes I should do today and today I am tackling the topic that's
maybe suggested to me the very most how how strong is one punch man well I think I know how strong
he is but more importantly I think I figured out how strong he could possibly be [Music]
one punch man took an interesting path to anime so I've actually made a couple videos in one
punch man already all right I'll talk about them after but uh I did a I did a couple calculations I
uh Quantified how strong this man is it was a web comic and then a manga and then it went to series
the protagonist saitama is basically the strongest being in the universe able to defeat any opponent
with just one punch the character is a satire of sorts and I think that's why we love it but if
you're the strongest hero ever how strong is that every explanation that I have seen basis saitama's
Powers off of this anime intro specifically that his fist is going so fast that it can heat up the
air around it like a space shuttle re-entering Earth orbit kind of like this or like this
feet I have a new editor I'm just testing him anyway these explanations also mistake this guy's
so funny Force for energy and use blue shifting and redshifting when I think it's not really
acceptable so let's abandon this reference point and look to what we can actually see
happening in the anime to find the true limit of saitama's strength first a direct speed comparison
in a fight with one of his strongest foes Lord boros he gets punted to the moon and then after
checking out how cool reduced gravity is he jumps back if the moon is 384 000 kilometers away I did
this calculation as well so is this the only one time between Thomas jump and his landing
at least in the anime is around nine seconds that means he has to move at least as fast as 43
000 kilometers per second that's 14 the speed of light astrophysicist Ethan Siegel that's
okay that's okay with me help me a lot on this episode also estimates that based on
saitama's mass and size he would be pulling trillions of G's and putting trillions of
atmospheres worth of pressure onto the moon's surface at least that explains this scene
the science saitama only gets more impressive from here Fire Punch
saitama can be but how strong is he or rather how much force can one of his punches provide in this
scene OPM stops a meteor with just one punch but to do this physics wise he would have to
dissipate all the kinetic energy of that meteor over the distance we did this one
too of his fist kind of like what happens when a car crumples around a tree if the
meteor is a city killer let's assume it to be a cube-ish thing with 60 meters on each
side the density of rock and a velocity of 17 kilometers per second if all if all the
kinetic energy wrapped up in this meteor comes to a stop within maybe half a fist's
distance or three centimeters then the average amount of force that a one punch man punch can
pack is three quintillion Newtons that's a big big number but maybe it's easier to
understand if you think of it like 90 billion Saturn V rockets taking off from your face
that may be how strong saitama is but we've never seen his full potential what is the real physical
limit of his strength the strongest a punch from one punch man could possibly be is one not
that destroys every foe but every thing I asked Ethan Siegel about this too and there is a punch
so serious that it could restart the universe the universe as we know it only exists because
it's period they've done that in the manga yet that's if that hasn't happened we all know that's
coming of inflation inflation or the instant where the universe went from almost nothing
to well everything stopped if we could well we don't actually know if that inflationary period
stopped it might have continued on beyond what we can see beyond the observable universe and a lot
of people suspect it might have and the universe might be much larger beyond the observable little
region we can see somehow restart inflation then the universe would begin to push itself
apart again to the point that even atoms would rip what kind of punch would that take one where
every particle inside Thomas fist has the energy to create inflation-related particles like some
hypothetical giant Atom Smasher and thus restart Cosmic inflation so if you estimate the number of
particles inside Thomas Fist and give them all a physicist recommended 10 to the 32 Giga electron
volts then one Universe destroying punch would have the energy of a thousand gamma-ray bursts
some of the most energetic events in the universe or all the energy from all the all the thermal
energy from all the particles in the sun in just your hand in just one fist so the strongest
saitama could possibly be the punch wouldn't look like this it would look something like this oh oh
that is the ultimate limit of a one punch man punch I should also add here this really depends
on inflation being a thing so it is a hypothesis there's not that much evidence for it at all the
revast uncertainties with all of these things in cosmology because um it's all on Shaky Ground so
inflation did it happen well we really don't know it looks like it might have and then if inflation
continued right the you know who knows how big the universe really is and what what happens if
the universe is infinite in size it might be um so you know if this does say inflation is
a thing right and then but the universe is also like infinite uh well you know that might not be
the end him he can already survive a vacuum so Thomas so who's to say he can't survive the bulk
yes I'm going to theoretical physics territory so it's like you know there are potentially things
outside our four dimensions of space-time three spatial Dimensions one temporal Dimension the bulk
which is like the background higher dimensional space time right whereas like we're in like this
brain which is like this embedded three plus one dimensional time like hyper surface in that
bulk thing we assume we live on like one one of these brains right you know this is straight out
of theoretical physics of course but inflation is still very much theoretical as well if we're gonna
go there and talk about theoretical physics well then I'm gonna say well maybe that's not the limit
maybe saitama could be even more powerful maybe he could destroy the bulk the higher dimensional
space time which is like all of the dimensions if if such a thing is even real so here we are again
not knowing how strong saitama is and I can't help you with figuring out how to destroy the
brain that that's beyond me you're gonna have to go talk to that guy over there who wrote that book
Kip Thorne Nobel Prize winner you might be like well how would he survive outside of our space
time the time doesn't exist in space well hey he was on the moon fine all right so who am I to say
he couldn't exist out there either maybe he's gone but really there is a limit right which is
if the universe is infinite well then I guess he's doesn't have a limit he is an infinite
limit which means there is no limit and if one the author of one punch man is out of
ideas for saitama and like where to take him because they've kind of reached the limits of
probably everything they've heard of right so well here you go there's some ideas and theoretical
physics you can take saitama even further we have not reached the limits of our imagination just yet
I want to see saitama destroy the bulk granted these energies are so big that we don't know
if the laws of physics break when you get to them although the laws of physics are already broken in
anime so I think we're okay plus the real strength of saitama doesn't come from physics it comes from
satire as long as there are beefy superheroes it's a spouting exposition to each other saitama is
going to be there and stronger than them so by definition he's already stronger than Superman
and the Incredible Hulk because science fiction writing [Music]
that was amazing can confirm Kyle Hill is a legend and that because
science is indeed correct here I think that was all pretty well done
