This isn’t a matter of advancing technology, or even our understanding of science. This is the short answer, but I will go into depth on why this cannot be true in our universe, even in the future. If they aren’t true, then, literally, nothing we know is right! These are fundamental properties of what we consider reality. But if you got the time machine from yourself, how could you also give it to yourself? The thing was never manufactured, it simply exists with no origin. So you go back in time, before you took the first trip, and destroy the time machine before you can use it.īut if you destroyed the time machine, you could never have gone back in time and messed things up, and would therefore not have a time machine to go back in time to destroy it before you could use it.įor more fun, where did you get the time machine from? Turns out, an older person just gave it to you, but you find out later that the older person is in fact your older, time travelling self. Things went badly, and you don’t like the horrible present which resulted from your trip. You have a time machine, and used it to travel into the past. Go back in time and change things so you were never born, means that you couldn’t go back in time to change things. Temporal Paradoxes: based on those two key principles, reversing time requires that things happen, which cannot logically happen.
Time travel makes things appear from nothing, or disappear into nothing, and that is not possible in our universe. Nothing ever happens without something to cause it to happen.Ĭonservation: Nothing is ever created or destroyed, only changed in form. The big problems: Causality, Conservation, Paradoxes.Ĭausality: Things happen because something happened to make them happen. I cannot change the laws of physics, Captain! - Montgomery Scott, Star Trek. It violates all known laws of physics, and is logically impossible. Is time travel possible? Simple answer, no.
