Time travel fascinates both scientists and storytellers, though it remains theoretical. Physics suggests that traveling through time would require exotic conditions such as wormholes or faster-than-light travel, neither of which are currently achievable. Even if possible, time travel introduces paradoxes, like the grandfather paradox, where altering past events could prevent the traveler’s existence. These logical challenges make time travel a complex puzzle. Nevertheless, exploring these concepts helps physicists understand the nature of space-time and the universe. Until proven otherwise, time travel stays within the realm of imagination and theoretical physics.
