I think time travel is not possible
I remember one of my Physics professor saying no object in the world can travel faster than light. Because as any object approaches speed equal to "C" (the speed of light), its mass approaches infinity. So at the speed of light, an object will have infinite mass
That makes it an impossible phenomenon. I'm not an expert on this topic but could gather some stuff from old physics lectures
I guess I'll keep my mouth shut and keep an eye on this thread.
