Is backward time travel possible?
But what about theories like the grandfather paradox?
The grandfather paradox is a paradox that arises in theories of backward time travel, where a time-traveler goes back in time and kills their own grandfather, preventing the time traveler's own birth. The paradox is considered to be an argument against the possibility of backward time travel, as it creates a logical inconsistency. However, many physicists believe that there may be ways to resolve the paradox, such as the multiple universes interpretation of quantum mechanics.
