History Quote by Brian Cox
““Later, we shall see that if it were possible to exceed the speed of light, we could construct time machines capable of transporting us backward through history to any point in the past. We could imagine journeying back to a time before we were born and, by accident or design, preventing our parents from ever meeting. This makes for excellent science fiction, but it is no way to build a universe, and indeed Einstein found that the universe is not built like this. Space and time are delicately interwoven in a way that prevents such paradoxes from occurring.””

Exceeding light speed could enable time travel, but physics prevents paradoxes, making such ideas fictional.
In simple terms: Time travel impossible due to physics.

A Different Perspective
Einstein’s relativity shows such travel contradicts known laws.
