Is it possible to make time machine and do time travel?
What are some of the paradoxes and complications that arise from time travel?
One example is the grandfather paradox, where if someone were to go back in time and kill their own grandfather, they would never have been born and therefore could not have gone back in time to kill their grandfather. This creates a logical inconsistency that cannot be resolved. There are also issues with altering the timeline and the potential for creating alternate universes.
