Is backward time travel possible?
That's really interesting. Are there any other proposed solutions to the grandfather paradox?
There are several proposed solutions to the grandfather paradox, including the Novikov self-consistency principle, which states that any action taken by a time traveler in the past must be self-consistent with the history that led to their travel, so that no paradox arises. Another proposed solution is the idea of predestination, in which events are fated to occur in a certain way, regardless of whether someone tries to change them. However, these solutions are still theoretical and have not been proven.
