you click off the video the story ends you wake up in your bed tomorrow and believe whatever you
want to believe you click the like button you stay in wonderland and i show you how deep the rabbit
hole can go don't go too deep though you'll end up in australia whilst we have some nice beaches
there's a lot of stuff that'll kill you like this thing all this thing welcome back guys my
name is dawn dance i'm a physicist from the land down under i'm a phd candidate in astrophysics
at swinburne university today we're going to break down some of the physics and science in the matrix
which might seem a bit unusual but i do theoretical astrophysics right
and we work with the biggest simulations humans have ever created so currently i'm working with
one called uchu this thing is almost the same size as the universe it's about nine and a half
billion light years from one side of the box to the other you might be wondering how close our
universe simulations are to the matrix and the short answer is not close at all don't worry
though mathematical anomalies in our simulations don't create neos at least i think the matrix
is a computer-generated dream world in order to change a human being into this be the truth stop
i don't feel like someone would react like that in real life i'd be like yep not surprised [ __ ]
like really we how we don't know what's going on like what the hell is going on
it would not surprise me if it's something like this i think this is a rather boring
this would be rather boring if it turned out to be something like this to be honest i
i'd hoped for more like you know something far more incomprehensible
hello neil who are you the guy from i am the architect
you're a liar if you say you've never tried this move as a child fun little fact about
this scene that you might not know is that they actually didn't use cgi for that scene
keanu reeves dodged real bullets so obviously in the matrix neo can do whatever the hell he
wants he's basically got but if we replace neo with say me i want to work out if i could dodge
these bullets because i'd love to be able to dodge some bullets so let's do some calculations i'm not
going to show any math don't worry don't go anywhere i'll work it out and i'll be right
back so in this scene i just worked out it would take the bullet about 0.02 seconds to get to neo
now that's a problem because the human reaction time is about 0.17 seconds so you're dead many
times so please don't try to dodge any bullets in real life you can't do it okay so i just worked
out the torque produced by neo's motion in this scene and it works out to be about 2.7 times 10
to the 6 newton meters now that's comparable to the magnitude of thrust produced by the
launch of the space shuttle the force required to break a human bone is only about 4 000 newtons
his knees would shatter i mean the magnitude of this talk would crack even diamonds this
is the construct it's our loading program we can load any i gotta get me some of those
glasses we're inside a computer program is it really so hard to believe this isn't real
what is real how do you define real taste and see then real is simply
electrical signals interpreted by your brain so i know this isn't exactly what he's talking about
he's talking about how our brain processes reality which is another whole thing entirely but i also
love another aspect to this which relates to one of my favorite ever quotes everything we call real
is made up of things we cannot regard as real but we know that it was us that scorched the sky
at the time they were dependent on solar power the human body generates more bioelectricity
than a 120 volt battery and over 25 000 btus yeah but the problem is we use most of that
humans are very inefficient batteries you know we require all this energy each day about 2000
calories and we use pretty much all of it so we are we would not make a good battery
that's a big problem i have with this film we're not going to dwell on it for too long though
there's a lot of problems i have with the actual science of this bit but combined with that form of
fusion the machines that's what i mean combined with a form of fusion that is like the biggest
throw away i've ever heard if these robots could do fusion why the hell would they need humans
as a battery source because fusion is what's happening at the core of the sun it pretty much
means unlimited energy because there's no shortage of hydrogen in the universe
fields where human beings are no longer born and that is exactly why i am not convinced
we should be broadcasting our presence to the rest of the universe i don't know if it would turn out
very great for us if we were to come across a more intelligent species out there especially one that
was capable of traversing the stars that means they'd be well ahead of us and look how we treat
i don't want to say lesser creatures but creatures that are different why am i here your life is the
sum of a remainder of an unbalanced equation inherent to the programming of the matrix
and that is my favorite scene and line of the series i love that so i'm going to try and avoid
things that i think a lot of you will already know because i want to touch on things you might
not know a lot of this stuff has been in the public domain for a while now so there's a lot
i will just skip for example you've probably all heard you know with the rate of computer
simulations and how much they're improving and how quickly it's probably not going to be too much
longer until we have something like the matrix you know like a really really realistic simulation
of reality where you can't distinguish between reality and a simulation of course that's coming
and then there's that other idea that you know elon's always spouting on about how you know if it
is possible to create a simulation of the universe well that means it's probably likely that we're
already in a simulation personally i do think it is possible to simulate a realistic universe
and a reality like we're currently in another little idea i have that i'll share with you guys
um you've probably heard of the fermi paradox which is about you know why there's no aliens
around you know when some of our calculations show that they should be they should be everywhere in
the universe but we don't see any well obviously like neil degrasse tyson has pointed out i love
this answer he goes it's like going up to the ocean getting a spoon of water and going
well there's no whales in the ocean but anyway i'm going to provide an idea for a solution to
said fermi paradox if we're living in a simulation and consciousness is a really expensive process to
simulate computationally maybe that's why we don't see other life out there in the universe because
within this big simulation you've got you know all the stars and you've got the planets there's not
much in between them you got the islands which are the galaxies and maybe that stuff isn't too
computationally expensive it's very easy to simulate maybe and the consciousness stuff
is really hard and so you can only have a little bit of it in the universe so if we really are in a
giant simulation like the matrix and consciousness is really hard to simulate well maybe we really
are the only life in the universe please remember this is all speculative there's a lot of gifts
there i'm doing it because it's fun if we are living in the matrix well maybe a physicist by the
name of jim gates will be the first to figure it out so this guy works on string theory stuff which
there is zero evidence for currently this guy's been looking for super symmetry all these courier
we're not going to talk about that we were meant to see it at the lac we didn't so it's not looking
good for string theory let me just say but anyway this guy found some really interesting stuff in
a deep level of string theory he found these error correcting mechanisms and if you've never heard
of an error correcting code in computing and programming well they're actually used to make
things like browsers work like like it basically helps the internet work okay so this led him to
sort of speculate in a semi-joking way that maybe we're living in a computer simulation
who knows but again string theory there's no evidence for it on a little bit of a deeper level
they've basically found these strange graphs which are equivalent to equations and these equations
within them have these things that are analogous to those error correcting codes so let's now talk
about the holographic principle as i promised earlier in the video because this stuff is crazy
and it's another 10 string theory so please keep in mind that there's no evidence for this stuff
but it's awesome and basically it arises from the fact that we don't have a quantum theory of
gravity we do for all the fundamental forces of nature the other three that we currently know of
potentially that other one that you might have heard we recently might have found but anyway so
we have quantum theories for those other gravity is a bit of an exception in general relativity
which is one of our greatest series we currently have in physics it has this idea of gravity being
the curvature of space-time all right it's nothing more however in quantum mechanics you know we have
no idea what gravity is but there must be some theory behind gravity in quantum mechanics and
so this is what we call quantum gravity and people have been working on this for decades
and pretty much no avail we don't have any great theory of it there's loot content gravity there's
string theory okay holographic principle is within string theory so the holographic
universe can be basically thought of as like a universe in virtual reality the idea is that the
three-dimensional universe we live in is basically projected from a two-dimensional screen of quantum
pixels and the physics on that two-dimensional screen give rise to the quantum gravity behavior
in the virtual universe so we've already mentioned quantum computing and error correcting codes in
this video already but now let's link what i'm talking about now to both of them because in 2014
some theoretical physicists found some really cool stuff and now working with the theoretical player
playground of choice called anti-deceitus space which is a universe that works like a hologram
you know we were just talking about this holographic principle right and to again
reiterate this idea is that the bendy fabric of space-time itself is a projection from entangled
quantum particles living on its boundary and they did calculations that suggest that this
holographic emergence of space time works just like a quantum computing error correcting code
so they're basically suggesting that spacetime itself is a code in this anti-descender universe
which we know we don't live in by the way so these quantum correction algorithms basically
find and fix errors within quantum computers okay they protect quantum information from errors that
arise basically due to uh decoherence and quantum noise a lot of quantums in there
you're really gonna have to look into some of this stuff for yourself because it's gonna take
way too long to explain all of these terms so this two-dimensional stuff in the holographic principle
uh reminds me of another really awesome thing that i've been reading about recently which doesn't
really have anything to do with the matrix or the universe being a simulation but it's equally crazy
and they've just been proven to exist and they're particles the quasi-particles i should say
that only exist in two dimensions the guy who discovered these theoretically was asked about
their properties and he basically said anything goes and that's where the name comes from
anions so like i said they're quasi particles so they're like a particle in that they have a
location and potentially a mass but they will they they're only observable as a collective behavior
of other more conventional particles you won't be able to ever isolate one of these things think of
the intricate geometric shapes made by group behavior in nature like a flock of birds or
a school of fish as they move around and you'll have what i'm picturing in my head
so the existence of these anions was originally inferred by something called quantum topology
which sounds really complicated but it's basically just the properties of the shapes made by quantum
systems and now there's actual evidence for these things existing which is awesome because there was
years of theoretical work that went into figuring out what the hell these things are
and these things again might be extremely useful for quantum computing
that'll do for this video guys thanks for watching make sure you like and subscribe i'm
gonna be making a spider-man video doctor strange video so stick around i'll catch you next time
