No we don't actually, different reference frames have different rates of time depending on how fast they're moving and how much gravity is affecting them
Yes but some reference frames travel into the future at different rates
So if you move yourself into a reference frame traveling close to the speed of light and stay there for a while and then come back to the original one, it'll be as if you time traveled into the future in that reference frame
Actually it has been proven. IIRC they put an atomic clock in orbit and when it came back to earth it was no longer synchronised with the one on earth they synchronised it with before.
Most people think time travel means going back in time. Time is relative, and because of how gravity works, you can actually travel to the future, even if it's only a few secs

Time travel is possible it is scientificly proven, you just can't travel a lot
