Exactly no time travelers ergo time travel not possible, other wise we would be overrun by tourists from the future.
A time machine that travels into the future is possible. Simply travelling at close to the speed of light would cause the traveller's watch to move slower than someone's on Earth. There is also suspended animation. You could be "frozen" for a 1000 years and wake up in the future - like Futurama. But you couldn't come back if you didn't like what you see.
It is possible to see images and hear sounds from the past - just as if we would have travelled back into that time period. But we can't change what happened. This technology already exists. It's called a movie camera and/or sound recorder.
To travel back into the past and relive that period, and possibly change history is not possible. Why? Twin paradox. Can you go back and see a "younger you" - law of conservation of energy and mass. What if you kill yourself or cause your grandma to never be born? Then how did you go back and cause yourself to never be born if you don't exist?
Based on our current understanding of physics, it should be possible to travel into the future - but not back into the past due to the paradoxes it would create.
But in the future, who knows?
bit of a stretch
yes
im from the future. yes.
thats to much for me...................
