Rejecting the possibility of time travel

Einstein's special and general theories of relativity both allow for time travel.

However, time travel, especially going back to the past, would create a conflict with the theory of causality.

In his book "The Universe is a unified object", author Ngo Quang Ha reconstructed the structure of time, ensuring that the physical principles still function correctly, while simultaneously refuting the possibility of traveling backward in time.
