Would forward and backward time travel ever be possible in the near future?

Question

If so, then how can we keep time travel a secret, for example, if I met my father in 1969 on the day he graduated high school?

If you think about it, how can you explain people who are psychic? Could it be possible that they came from the year 2060?

If it is possible, here are some major events that need to be changed from the past:

1) September 10, 2001- Tell all airports in the U.S. to raise security to prevent the terrorist attacks of the following day.

2) November 22, 1963- Tell President Kennedy to cancel his Presidential nomination rally in Dallas to avoid getting assassinated. Then, arrest Lee Harvey Oswald for possession of a deadly weapon.

3) December 8, 1980- Arrest Mark David Chapman for loitering outside of John Lennon and Yoko Ono's home in New York City to prevent John's murder.

Answer 1

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.

Answer 2

Have you met someone from the future?

that is your answer

Answer 3

Good questions, but I don't think its possible!
