We all can time travel, since we are always moving forward to the future.

Theoretically, according to Einstein's theory of Relativity and normal Physics, time travel is possible. There is a relation between motion and time. In theory, the faster you go, the slower time becomes for you. When you reach the speed of light, time stops. When you travel faster than light, you begin to go back in time.
Consider this story. Sarah and Sam are twins. Sam stays on earth while Sarah goes off in a spaceship with a velocity nearly equal to that of light, orbits a star and returns in what she thinks was one month. When she come back, Sam will be 5 years older than her.
That is the simple theory of traveling to the future. The practicability of this must be questioned. You can never travel as fast as light. With speed, mass increases a lot. By the time one reaches the speed of light, one's mass would have become infinite.
There is something called the Grandfather paradox. Suppose you travel so much faster than light that you land way back to the past, to the childhood of your Grandfather and kill him before he meets his future wife (your grandma). That would make it impossible for one of your parents to have been born and there would be no you in your grandmother's future. then, there would be no one to travel back in time and kill your grandfather later in your grandmother's future. But here you are, having done the deed. So, since later it implies that you never existed, who travelled back in time? A shadow, a ghost? See how confusing it all becomes?
Theoretically, time travel is possible. Practically, far from so.

I did already, I travelled back to answer your question before you asked it but apparently YA doesn't have that facility yet.

I remember that name too. Hmmm, I'll have to check my previous posts.
I'd like to travel, but who has the time?

No. No mistake...no one wants to know if they can time travel today. Dude, its Tuesday...NO ONE asks about time travel on Tuesdays...sheesh!

I'd love to travel through time. In fact, my husband and I were just talking about this...
There are so many things I'd love to do...
I'd see Elvis perform when he was in his prime, go to Woodstock, stand behind the grassy knoll when jfk was shot (so I'd know what really went down)...
what would you do?

Technically we are all stuck in one time frame in that it is always now.
But we are moving foward through time,thus creating the time paradox.......or some thing relating to that.
