The question about us living in a computer
simulation designed by a higher life form has bugged many for a very long time even
Elon Musk suggested that the development of simulations “indistinguishable from reality”
was inevitable. The likelihood that we are living in “base reality,” he concluded,
was just “one in billions.” So, how likely is that we are living in a
computer simulation? If you are new to this channel hit the thumbs

that ‘simulation theory’ will be proved, just as it was proved that the Earth was not
the center of the universe. Musk is just one of the people in Silicon
Valley to take a keen interest in the “simulation hypothesis”, which argues that what we experience
as reality is actually a giant computer simulation created by a more sophisticated intelligence.
If it sounds a lot like The Matrix, that’s because it is.
One popular argument for the simulation hypothesis came from Oxford University’s Nick Bostrom
in 2003. In a paper titled “Are You Living In a Simulation?”, Bostrom suggested that
members of an advanced “posthuman” civilization with vast computing power might choose to
run simulations of their ancestors in the universe.
This argument is extrapolated from observing current trends in technology, including the
rise of virtual reality and efforts to map the human brain.
At the same time, videogames are becoming more and more sophisticated and in the future,
we’ll be able to have simulations of conscious entities inside them.
Forty years ago we had Pong – two rectangles and a dot. That’s where we were. Now 40
years later, we have photorealistic, 3D simulations with millions of people playing simultaneously
and it’s getting better every year. And soon we’ll have virtual reality, we’ll
have augmented reality,” said Musk. “If you assume any rate of improvement at all,
then the games will become indistinguishable from reality.
Not everyone is so convinced by the hypothesis. In order to make the argument in the first
place, we need to know what the fundamental laws of physics are where the simulations
are being made. And if we are in a simulation then we have no clue what the laws of physics
are. As the Physics we know would be the simulated laws of physics.
Richard J. Terrile believes that recognizing that we are probably living in a simulation
is as game-changing as Copernicus realizing that the Earth was not the center of the universe.
“It was such a profound idea that it wasn’t even thought of as an assumption,” he said.
Before Copernicus, scientists had tried to explain the peculiar behavior of the planets’
motion with complex mathematical models. “When they dropped the assumption, everything else
became much simpler to understand.” Just in case it’s been weighing on your
mind, you can relax now. A team of theoretical physicists from Oxford University in the UK
has shown that life and reality cannot be merely simulations generated by a massive
extraterrestrial computer. In a paper published in the journal Science
Advances, Zohar Ringel and Dmitry Kovrizhi show that constructing a computer simulation
of a particular quantum phenomenon that occurs in metals is impossible – not just practically,
but in principle. They discovered that the complexity of the
simulation increased exponentially with the number of particles being simulated.
If the complexity grew linearly with the number of particles being simulated, then doubling
the number of particles would mean doubling the computing power required. If, however,
the complexity grows on an exponential scale – where the amount of computing power has
to double every time a single particle is added – then the task quickly becomes impossible.
The researchers calculated that just storing information about a couple of hundred electrons
would require a computer memory that would physically require more atoms that exist in
the universe. And given the physically impossible amount
of computer grunt needed to store information for just one member of this subset, fears
that we might be unknowingly living in some vast version of The Matrix can now be put
to rest. Thank you for watching, If you are new to
