Is Time Travel Possible?
- evo_9 16y agoMaybe it's my scifi/fiction writing past but I've always thought that time travel is a possibility someday. Perhaps it's that the universe/laws of physics prevents physical, solid matter from moving through time. In the far future we may discover a way to send pure energy - aka our pure consciousness - through time, allowing one to witness history as a sort of ghost (sort of time travel telepresence). This would prevent someone from affecting the timeline because no direct interaction would be possible as well.
- Locke1689 16y agoWhile everything in this article is factually correct, it maybe gives a different impression than it should. Time dilation is of course a long held tenet of special and general relativity. Can we call that time travel into the future? I'm not really sure. In a way I guess it is (how is it practically different from placing yourself into a separate bubble of spacetime?). Of course, actually achieving this in a practical sense is pretty much impossible considering the energies involved. As for time travel into the past... pretty much no. That would have a bunch of really disturbing consequences, including traveling faster than the speed of light and violating the second law of thermodynamics. Of course, this just a former physics minor on stupid macro affects. When you get down to the quantum particle level the game probably changes considerably.
