today did you do a smart person my name jeff i'm kidding my name's dylan i'm a physicist
from the land down under welcome to the physics club grab a chair grab a coffee
grab a vegemite sandwich look grab whatever you want and let's talk some natural philosophy
so i had to do that party pop-up because we just hit 30k subscribers who knew so many people would
want to watch a guy dressed in a suit watch some anime talk about physics but apparently people do
so i'll keep making them if you guys keep watching uh give me some suggestions down below in the
comments i certainly read through everything you guys have to say i remember reading a comment on
the last video someone was like why do you always read the bad comments well i don't know if they're
going to be bad before i read them or not right so whenever someone leaves a negative comment i'm
always so tempted to just be a massive troll and say something funny but we've got to keep things
professional around here even though i'm not wearing any pants it's friday you're all very much
appreciated the good and the bad and i just want to say a special thanks to all my patrons you guys
are amazing you really helped support me a lot um i also want to say a huge thanks to everyone who
has messaged me on instagram there are some really lovely people sending really massive messages
i'm sorry to everyone who i have yet to reply to i will get there eventually i'm way too anti-social
for social media also for all the people that are wanting closure at the end of the videos i
will add an ending today so stick around for that i have been doing it for a very particular reason
which no one seems to have caught on to yet in the comments so comment down below if you can figure
out exactly why i end the videos like that there's a very specific reason there's usually a reason
why i do most things in the video the particular editing it's a bit like life right you don't know
when it's going to end just ends without any warning so i actually filmed this uh video
quite a while ago but i wanted to say thanks to everyone for the subscribing so here we are um
and if you haven't already please apply some time derivative of momentum onto that subscribe button
and let's get into the video so today we're putting my many many years of university education
to great use by watching anime going to be watching and reacting to dr stone i have no idea
what this show is about i know it's anime um but it's probably my most requested thing to react to
so let's check it out why not do a little bit i don't know how much physics is going to be in
the show so i might just be going on some tangents to talk about some cool things but we'll find out
before we start the video i also just want to say you won't find any serious physics here but you
will find some extremely fun facts and that's what this channel is all about fun facts i just want
to get across some cool information and try and change people's opinions about things like physics
and science i'm just trying to open some people's minds and show them how astonishing and incredible
uh and wondrous this place is uh not many people really look into it enough to truly appreciate how
incredible it is and i'm just trying to inspire some people to look more deeply into things
because almost everything is interesting if you look into it deeply enough probably the only
human in the multiverse to put on a suit to watch anime but you know what i'll take that achievement
but i promise to cheer you on so vociferously my vocal cords will snap awesome what about hair
we might need a whole episode just to explain the physics of that hair he's got maybe
all right he's turning to stone it doesn't look like normal like there's stuff in it
whether that's physical stuff or just some sort of optical illusion it looks
like physical stuff it's green light so it's in the visible light domain of electromagnetism
all right so there's a dog why hasn't the dog been turned to stone
so would this be possible in real life is it possible to turn
people to stone with nothing but light well i mean it's i'm making that assumption right because
it might not have been just light it looked like light but it could have been like some
you know microscopic things right like nanobots and maybe that's what's uh responsible for turning
them into stone and that would make a lot of sense there's currently some stuff happening
with nanobots actually i think they're trying to use them to essentially destroy cancer so that's
pretty cool could be a thing of the past cancer i also was reading a study recently how they're
using nanobots to help beat heart disease atheros arthro arthroscopy arthro jesus christ so is there
any way it could just be light turning people into stone nothing that i'm aware of um i mean light is
hella mysterious itself do we have a pretty good understanding of it it seems so but it's
also there's also some really crazy things about light like it's got a bunch of insane properties
for instance did you know that we don't think time passes for light yeah it also is made up
of things that have zero mass right just think about that first one for a minute if
light doesn't experience time it means it's everywhere and anywhere instantaneously so you
know if you didn't know it takes light about eight minutes and 23 seconds i think it is
for light to get from the sun to earth because it has a finite speed right the speed of light which
is 300 000 kilometers per second ridiculous but it takes it about 8 minutes and 23 seconds to get to
earth but for photons which are the little things that make up light the journey was instantaneous
and you can take that further what about light that's traveled you know 12 billion light years
you know we see quasars out there in the universe in the distant past 12 billion light years away so
just try and wrap your head around that it took 12 billion years for that light to travel that
distance to make that voyage but it experienced no time no time elapsed for the photons
yeah anyway we're often a massive tangent in conclusion no i'm not sure light could turn
people to stone though i definitely do not know everything in fact i know very little the more
you know the more you realize you don't know and i certainly don't know as much about the universe
as i'd like so it could be possible of course um i think it's probably nanobots i don't think
it's a light it looked like there was stuff in it um and there's nothing that's coming to mind
and i did read that this show is trying to be scientifically accurate and if that's the case
you know that i'm just going to assume they're trying to be scientific and there must be some
sort of scientific understanding that we're currently aware of in our time
so it looks like nature is reclaiming the planet i don't think would take too long um
for it to be like we never existed at all and there's going to come a time in the future if
you didn't know the oceans are going to evaporate in about a billion years because the sun is slowly
expanding um and yeah it's going to heat up the planet oceans are going to evaporate unless we've
gotten off this floating rock and found another floating rock yeah we're pretty pretty effed
really slept in for a hell of a long time that's uh i'm sure you know that one
einstein's famous energy mass equivalent energy and mass the same thing
because it's mass times the speed of light squared for a very little bit of mass you get a lot of
energy because the speed of light is 300 000 kilometers per second and you square that times
it by a very small number and you've got a hell of a lot of energy which is why atomic bombs are so
so awful so is this guy like what sort of scientist is he can someone let me know in
the comments is he a physicist he's an engineer just knows everything from him
it's pretty cool yeah it's gonna the highest melting point of any elements we know of
um and you know it can glow white hot and not melt so you can run electricity through it right
so there's not a whole lot of physics stuff going on
there's a lot of engineering though so i'll leave that one for the engineers to explain
but if you enjoyed this and you'd like me to try harder and watch some more comment down below
and i'll consider it alright you've made it to the end of the video thanks for sticking around
so here is your closure the video is now ending have a good day uh and i'll leave you with a
fireman quote study hard what interests you the most in the most undisciplined
irreverent and original manner possible i'll catch you smart people in the next one
