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

635 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.

There’s a pretty simple justification for thinking it’s at least possible. **IF** an intelligent species can simulate minds **AND** there’s some reason to run such simulations, **THEN** there would be many simulations and only **ONE** true reality. Given those facts, we’re probably not the one true reality (cuz there’s only one).

Of course, it depends heavily on the IF part. We don’t know if it’s possible or if there is any reason to want do it. There is no evidence, yet, that it is (or isn’t) true. If it was true, there would be little-to-no practical impact on you, specifically. It’s not like we comprehend what we’re missing out on. maybe it’s a little scary to think we exist at the whim of some person simulating us, but I don’t personally see how it is any different than the normal existential dread of being a tiny, insignificant mind that will one day disappear into nothingness and it could happen anytime from random accidents.
