Is Time Travel possible? I personally have no idea. The science of time travel is too much for my mind. If someone is able to time travel to the past, just one little thing could make so many changes to the future that it could be a different world than the one that the time traveler came from, so it wouldn’t be the past of the world you came from. Perhaps at that point the universe would split off into multiple universes like they have in the TV show Fringe. Who knows, time travel could be possible, but I have a feeling it may just be impossible.
