Well, by definition everything that cannot be disproved, is theoretical possible. (Just like god) But I see no reason to assume such a scenario to begin with.

Well, by definition everything that cannot be disproved, is theoretical possible. (Just like god) But I see no reason to assume such a scenario to begin with. Are there any indications at all, it is a simulation? Then I would see a reason to figure out complicated experiments, that might hint at something. But I don't. And I see no convincing experiments or any solid theory at all, by those who propose that theory.
