It’s impossible to create a paradox, because the events that led to you being able to go back in time were created by whatever you did in the past in an attempt to change the future.
If you did successfully change the past so that you never ended up going back, you would not live the life where you go back in time to make that change. But if you did find yourself even going back in time it means your efforts already failed anyway, so might as well not even bother.
- maxerickson 6y agoIt's possible that reality is defined by different rules than you are reasoning with. (I don't think arbitrary travel backwards in time is possible in our universe; there could be very rare circumstances where it ends up occurring, but not where you can build a device that takes you anywhen)
- paxys 6y agoThis is the "there's no such thing as free will" argument, which is even more implausible than time travel.
- xwdv 6y agoIf cause comes before effect, then there is free will but there is a limited possibility of effects. If cause comes after effect, there isn’t free will but there is an unlimited possibility of effects.
