The idea that we live in a simulation is referred to as the "simulation hypothesis". The heart of this line of thinking is that our universe was created by some advanced form of intelligence, far superior to any living beings we could think of. It's an entity that created a simulation of our reality and existence. And the world that we know today was created just using His version of "computers".
Some scientists have actually taken things a bit further than just pondering about this sophisticated idea. For example, Stephen Hawking thought we had a 50% chance of being living in a simulated reality. That's why he was backing the "Breakthrough Listen" project. This is a project that aims to look for strings or any other signatures that would prove that we're part of a giant computer game.
But let's go back in time first. The simulation hypothesis began to take hold in the early 2000s, after a paper was published by Nick Bostrom, a professor at Oxford University. As he suggested, it is not at all beyond the realm of possibility that in the history of the universe, technology will develop that will enable beings to construct computer simulations of complete worlds. There may be many more computer simulations than real worlds. And if that's the case, there could be many more beings trapped in a simulation than those who aren't.
Given all this, one might even come to the conclusion that we are more likely to be in a simulation than not. But just when you think that it sounds so unconvincing, well, we found that there are no obvious indications that we're not in a simulated reality.
So far, we haven't touched anything from science. So, let's take a look at one area of physics that might be linked to this simulation hypothesis.
When we delve into quantum mechanics, we discover that it offers useful hints about whether or not we're living in a simulation. For example, when we track the position and momentum of a subatomic particle, we only observe that it behaves like a wave until we look at it, after which it becomes a particle. This is the notion that a subatomic particle exists as a wave of probabilities, or what's known as the quantum probability wave. So before the wave collapses, we can't come to any definite conclusions about the particle's reality.
One question you might ask is... Why isn't everything certain at the tiniest level of our existence? Well, one reasoning behind this might be due to the computing power. Imagine, in order for all particles in the universe to exist, all of their possible states of existence must be calculated. That would certainly require massive amounts of computer's capacity, for everything to be computed. After all, it's just more efficient to create some sort of probability.
Now if you think about his interpretation, everything happening at once is akin to being part of a giant computer game. In this game, we are all playable characters, staring at each other wondering what's about to happen. We are all helpless epiphenomena who flit through time and space. With nothing but our delusions of understanding.
We touched upon the idea that all probabilities exist until one particular outcome is observed. It's called quantum indeterminacy (QI).
If we assume the existence of QI and hidden levels of reality, it would mean that there must be some sort of mechanism present to hide information from us until we’ve observed it one way or another. Let's say you were not looking at a room right now but every single object in the room existed as both spread out waves and localised particles until you observed them. This could possibly suggest a fourth dimension where all probabilities exist at once.
The simulation hypothesis could just be a thought experiment that gives us a small glimpse of how QI and hidden levels of reality might coexist. If it does come true, we would have to assume the existence of other universes as well as physical laws beyond our knowledge. This would simply tell us one thing; reality is way bigger than we can ever imagine. And the main difference being, the architect of this universe would be an external observer, who can exist outside of it entirely.
The idea that our universe is nothing more than an elaborate supercomputer simulation is actually quite frightening.
