> Any chance we could find out? So, let's say we find out that we live in a simulation. The question now becomes: is the outer level a simulation as well? And so on. If we find out we do not live in a simulation then the question is: what originated us? (Which in some sense is like asking "do we live in a simulation?": we are still asking about the origins of this reality). Physics can tell us a lot about this reality but it won't ever be able to tell us anything about the origin of it (I'm not talking about Big Bang, but the origin of the Big Bang and the origin of the origin of the Big Bang, etc.) We'll never find a definitive answer that satisfies us.
