Traveling forward in time is not a problem. You’re doing that now. Can we travel backward in time? There is a theoretically possible way to do it using wormholes.

One solution to general relativity predicts an Einstein Rosen bridge, which is a type of wormhole. If this is real, they could also allow us to travel back in time.

Einstein’s field equations are nothing but a tool to understand how matter affects the curvature of spacetime and how spacetime affects matter. So we can imagine almost any creative spacetime curvature that results in a worm hole, and then by solving the field equations figure out how the matter in this spacetime must be configured to obtain that desired curvature.

One solution can form a spacetime curvature that is like a tunnel or shortcut between two points in space. These points can in principle be very far apart in space, or they can also be different points far apart in time. By traversing this wormhole, you can effectively travel faster than the speed of light.
