what do physicists mean when they say we potentially live in a simulation?

617 views

I get what a simulation is, at least in the very literal sense. What I’m experiencing feels like reality, it would have to, it’s all any of us have ever known. But what would it mean for us if we truly lived in a simulation? Can it just be turned off and we cease to exist? If we found out we did live in one, how could it change our reality? How do we even hypothesize such a thing? I have zero background in physics just so we’re at an understanding of my physics understanding.

It’s similar to how people used to say that fire could be classified as living.

There are a set of criteria for defining what a simulation is. Stretching the definition a bit, the universe as we know it fits into those criteria. Arguably, you could interpret this as the universe being a simulation, but like most similar philosophical oddities, it’s more accurate to say that our definitions are flawed than to actually seriously believe we’re just nth dimensional Sims. It’s a fun or interesting thought experiment **taken too literally by people outside the field**.
