Time travel is possible?

Question

Time travel is possible?

Answer 1

Of course, we do it all the time.

If you mean at faster then 'normal' though, you have to get into a very fast spaceship that can go a significant percentage of the speed of light. Things will seem normal to those onboard, but looking outside they will see the universe running faster than normal - and anyone outside looking in will see the space travelers moving in slow motion.

If you travel fast enough for long enough, years, centuries, millennia can go by outside while only months pass on board the ship. When you stopped everything and everyone you've ever known would be long gone, you wouldn't be able to understand the language your remote descendants were speaking, and you would be a stranger in their world.

So time travel is possible, but only in one direction, and there is no going back.

Answer 2

If it was possible then someone would travel are time. Im just making it clear.

Answer 3

As far as we know time travel is possible in one direction.  If you were to move really fast (say near the speed of light) for some amount of time, then when you stopped you find everyone around you many multiples of the amount of time you spent traveling older.  Look up special relativity.
