Time Traveling is possible in a theoretical sense but not in reality.

In reality it's not possible to time travel to the future or back especially like in the movies.

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.

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 with the use of a hypothetical device known as a time machine.

In reality we are actually traveling into time although not with a time machine.

Every second, minute, day, year etc that goes by means we're time traveling into the future.

Is time travel possible? Short answer: Yes, and you're doing it right now hurtling into the future at the impressive rate of one second per second.

You're pretty much always moving through time at the same speed, whether you're watching paint dry or wishing you had more hours to visit with a friend from out of town.

In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever.

The past would therefore still exist, just as the future already exists, but somewhere other than where we are now present.

One significant limitation of such a time machine is that it is only possible to go as far back in time as the initial creation of the machine; in essence, it is more of a path through time than it is a device that itself moves through time, and it would not allow the technology itself to be moved backward in time.
