Question

Is time travel possible? if yes how?​

Answer 1

Explanation:

Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, traversable wormholes, and Alcubierre drives.

Answer 2

Answer:

This can be achieved by traveling at relativistic speeds or through the effects of gravity. For two identical clocks moving relative to each other without accelerating, each clock measures the other to be ticking slower. This is possible due to the relativity of simultaneity.
