Time travel has fascinated scientists and storytellers for generations. While fictional in most respects, physics offers intriguing theories. Einstein’s theory of relativity suggests that time slows down near light speed or in strong gravitational fields—known as time dilation. Wormholes, hypothetical tunnels through spacetime, could theoretically connect different points in time and space. However, practical time travel faces enormous challenges like infinite energy needs and paradoxes. Quantum physics introduces even more complexity, with theories of multiple timelines and parallel universes. While time travel remains speculative, studying it helps physicists test the boundaries of our understanding of the universe.
