Is Reality Real? The Simulation Argument

by birtanpublished on September 12, 2020

We humans are unable to experience the true nature of the universe unfiltered our senses and brains can only process a fraction of the world so we have to use concepts and tools to learn about the true nature of reality technological progress not only widened our knowledge

About the universe it also made us aware of the unsettling possibilities in the future it might become possible to simulate entire universes but if this is an option how can we know that it's not already happened what if we are not

Creators but creations is it possible that we are not real and we don't even know it if our current understanding of physics is correct then it's impossible to

Simulate the whole universe with its trillions and trillions of things but we don't actually need to anyway we only need enough universe to fool the inhabitants of our simulation into thinking that they're real

Who needs billions of galaxies we only need the space our subjects are allowed to explore just be a flat projection and they would have no way to know what about small things like cells or bacteria we don't really need them when

You use a microscope what you see could be instantly created same with atoms the chair you're sitting on right now does not need to be simulated with quadrillions of atoms we just need the outermost layer of it it might be empty

Inside until you decide to break it open your body might feel like it's filled with bubbly things but it might be empty until you open it the minimum requirement for our simulation is only the consciousness of our virtual humans

Our subjects just need to think the simulation is real okay so are we being simulated well maybe but there are a few conditions that need to be met obviously we have no authority over this topic so please take

Everything we say with a grain of salt based on a modified version of the original simulation argument by Nick Bostrom we have five assumptions for you if they're true you dear viewer are living in a simulation assumption one

It's possible to simulate consciousness nobody knows what consciousness is for the sake of argument let's assume that you could generate consciousness by simulating a brain brains are pretty complex if you count every interaction

Between synapses as one operation your brain runs at about 10 to the power of 17 for 100 million billion operations per second let's generously assume we need 10 to the power of 20 operations to simulate

One second of human consciousness but we don't want to simulate just one human we want to simulate all of human history at once so we can skip around let's say we want to simulate 200 billion humans with an average lifespan of 50 years one year

Has 30 million seconds times 50 years times 200 billion humans times 10 to the power of 20 operations so we need a computer able to handle a million trillion trillion trillion operations per second more operations than there

Are stars in the observable universe a computer like this is just impossible except maybe it isn't assumption to technological progress will not stop anytime soon if we assume that technological progress continues in a

Similar fashion as it has so far then there might be galaxy spanning civilizations with unlimited computer power at some point beings on a technology level so advanced that we could barely distinguish them from God's

A computer that can handle a million trillion trillion trillion operations is serious business but there are actually concepts for computers which could handle this the matryoshka brain is the theoretical mega structure made up of

Billions of parts orbiting a star feeding on its radiation a computer of this scale would have enough power to simulate many thousands if not millions of humanity's at the same time under technologies like high-end future

Quantum computers might lower the size drastically so it might be possible to do this with a structure the size of a large city or even smaller but only if there's still someone around to build the computer assumption 3 advanced

Civilizations don't destroy themselves if there is a point at which all civilizations destroyed themselves this whole discussion ends here looking into space you'd expect a universe filled with millions of alien civilizations but

We see nobody the reason for this might be great filters great filters are barriers life has to overcome like nuclear war asteroids climate change or a black hole generator if life is inherently self-destructive then there

Are no simulations we explain this in more detail in our Fermi paradox video assumption for super advanced civilizations want to run simulations when we speak of posthuman civilizations we don't know what we're dealing with to

Think we know what beings as powerful as gods want is pretty arrogant imagine the smartest ant on earth living next to an amusement park it's curious about what humans are up to so you try to explain unfortunately the ant just doesn't

Understand the concept of rollercoasters and standing in lines and holidays and fun doesn't make sense to an ant living an ant life it's the same with us and a post human being compared to them we are ants running simulations for fun

Or science might be an absurdly stupid idea to them but if they do want to run simulations for whatever reasons and assumptions one two three are true – then the chances are not zero that you are living inside a simulation

Assumption 5 if there are a lot of simulations you are probably inside a simulation if there are simulated civilizations it's likely that there are a lot of them after all we assume that post human

Beings have access to practically unlimited computing power so if they run simulations it would be convenient to run millions or even billions of them if there are billions of simulated universes there are probably trillions

And trillions of simulated conscious beings which would mean that the vast majority of all conscious beings that will ever have existed are simulated so for every conscious being made of flesh a billion simulated ones exists since we

Have no way of knowing if we are simulated or not in this case the chances of you being one of the nine hundred ninety nine million 999,999 simulated ones are pretty high so what you consider reality might not be real

At all you really might be simulated all of this is based on a lot of assumptions that we can't really test right now so many scientists disagree with this whole thought experiment so don't burn your house down to test if there will be

Glitches if you are simulated not that much changes for you you might be on a small planet speeding through eternal nothingness or a simulation inside a computer your existence does not become more or less scary and bizarre all we

Can hope to do is try to live good lives and have a good time and hope that if we actually are simulations in a supercomputer nobody trips over the power cable oh oh oh no I think I just unplugged the

Simulation but what if that doesn't matter what if we are in one right now what if you are simulated Jake over at Lisa's 3 is looking into that click here to watch his video and subscribe to his channel why are you still here
