Do we live in a virtual reality? Is the universe emerging from an information processing system? And we can tell it? Can you hack the system and change reality?
Those are all questions that the simulation hypothesis presents. According to the simulation theory, all of reality, including the Earth and the rest of the universe, could in fact be an artificial simulation. For example, a computer simulation.
Leading researchers from physics, cosmology, mathematics, and information sciences have contributed to the simulation hypothesis.
The idea is that our physical reality is part of an increasingly sophisticated game-like simulation. Well, it is a bit hard to believe it. But check out the documentary trying to explain the hypothesis.
