Time Travel

Is it Science Fiction or Non-Fiction?

To many people time travel is a fictional topic, or simply a dream but many physicist have had plausible theories of time travel like Albert Einstein and his theory of relativity. Technically traveling to the future is possible right now, because of time dilation astronauts are time travelers. If you were to go up into space in a satellite with a clock, each day you would gain 38 microseconds on the clocks as opposed to a clock on earth. This actually proves Einstein's theory of relativity because this shows time is not the same everywhere in every condition, time can vary depending on where you are in space-time. I know this sounds pitiful-going forward in time not even a 0.0001 of a second but to go forward in time an extreme amount you would need to move faster than light.
