      Not in the way it is portrayed in films sadly. It would require some serious changes to the laws of physics, such as faster than light travel.

      You can travel into someone else’s future though. Time travels slower in high gravitational fields or at high speeds. So if you were on a spaceship travelling near the speed of light, or hanging out near a neutron star or black hole for a while then a matter of hours for you could be years back on Earth.
