So a deterministic simulation, if we can eventually create a simulation ourselves, shouldn't we be able to recreate our universe and if so, aren't we facing paradoxes and alot of stuff by being able to look into the future?,(reply>), @14u73 Well, you do have a ton of math paradoxes if they run deterministic and happen the way our universe does, HOWEVER, in theory it could be that this machine can show many future universes, from where we are, with our past branches but it would be impossible for us to project the correct future universe with our machine, or something.,(reply>), Jonatan arvidsson Not necessarily. If you interpret quantum mechanics using Everett‘s Many Worlds you might be fine. It‘s the “same“ as with time travel.
