Detailed explanation-1: -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.
Detailed explanation-2: -Time travel is possible based on the laws of physics, according to researchers. But time-travelers wouldn’t be able to alter the past in a measurable way, they say.
Detailed explanation-3: -As you might expect, the possibility of time travel involves those most extreme objects, black holes. And since Einstein’s theory is a theory of space and time, it should be no surprise that black holes offer, in principle, a way to travel through space, as well as through time.
