Solving Paradoxes of Time Travel Using the Many World Interpretation Theory

Abstract

My primary motivation came from a remark that I had heard the Leader of Opposition make in one of the conferences that I had attended, "Can we go back in time to undo what has been done?" I thought and thought about it for a while. After sometime, I was watching one episode of the Big Bang Theory, and I found my answer in one of Sheldon's explaination of time travel. I then used the Everest interpretation to demonstrate the possibility of time travel in a self consistent framework. The following paper aims to consider each universe as a separate quantum system and thus, aims to apply the basic principles of quantum mechanics to argue that no 2 universes share the same wavefunctions. We thus use the multiverse theory to solve the basic paradoxes related to time travel, in which reality transitions occur by shifting between pre-existing universes rather than modifying an existing one. Furthermore, the No-Broadcasting Theorem by Barnum et al. is applied to demonstrate that no two universes can share the same wavefunction, providing rigorous basis for the uniqueness of each universe.
