Actually it's the opposite way round. Time travel into the future is not only real but many many people do it every day. Fly across the Atlantic and because you are further away from the gravitational pull of the Earth, for you time runs slightly slower compared to someone on the surface. When you arrive, in a very real sense, you have travelled a tiny fraction of a second into the future. Do the same thing around a neutron star and for you a few minutes might have passed but when you return to Earth, you could find yourself millions of years in the future
with no way back.
Theroretically there is nothing forbidding time travel into the past but doing so can potentially cause so many paradoxes that many physicists believe that there will be some as-yet unexplained mechanism which will prevent it.
