Answers
Time travel is the concept of movement between certain points in time, analogous to movement between different points in space by an object or a person, typically using a hypothetical device known as a time machine. Time travel is a widely-recognized concept in philosophy and fiction. The idea of a time machine was popularized by H. G. Wells' 1895 novel The Time Machine.
It is uncertain if time travel to the past is physically possible. Forward time travel, outside the usual sense of the perception of time, is an extensively-observed phenomenon and well-understood within the framework of special relativity and general relativity. However, making one body advance or delay more than a few milliseconds compared to another body is not feasible with current technology. As for backwards time travel, it is possible to find solutions in general relativity that allow for it, but the solutions require conditions that may not be physically possible. Traveling to an arbitrary point in spacetime has a very limited support in theoretical physics, and usually only connected with quantum mechanics or wormholes, also known as Einstein-Rosen bridges.
acording to einstien theory of relativity
we can travel through time if can manage to cross the speed of light
as we travel faster and faster then the time is becoming slow if we travel as fast as light then the time travells backward.
so in this manner we can do time travel.
but
it is impossible as we travel as fast as the speed of light then we need a great amount of energy in fact if we travel in the speed of light or travel faster than speed of light we need an infinite amount of energy which is impossible in this time and the mass of the object traveliing in the speed of light will become heavier and heavier and become infinte if we cross speed of light
light particles photon can travells through speed of light because there is no mass of light particles called photon
