The subject of time travel has intrigued both scientists and science-fiction writers alike for centuries, but now scientists are suggesting that the concept is theoretically sound.

Back in September of this year, UK physicist, Professor Brian Cox, declared that time travel was certainly possible, but only to the future and not to the past.

"The central question is, can you build a time machine? The answer is yes, you can go into the future," the University of Manchester professor told the audience during a speech given at the British Science Festival. "You’ve got almost total freedom of movement in the future."

Have you ever regretted a missed opportunity to send a message to someone? Did you think that your life may well have been different if you had communicated certain things, and you would give anything to re-live that moment again?

According to scientists from Jesus College, Cambridge, U.K., you may get your chance to right the wrongs of the past – in the future.

Ronald Mallett, a physicist at the University of Connecticut, believes he knows how to build a time machine. He has designed a machine that can transport anything from an atom to a person from one time to another. ?I hope to have a working mockup and start experiments this fall,? he says. ?I would think I was a crackpot, too, if there weren?t other colleagues I knew who were working on it. This isn?t Ron Mallett?s theory of matter; it?s Einstein?s theory of relativity. I?m not pulling things out of the known laws of physics.?

Alan Guth, a physics professor at MIT who has studied the theory of time machines, says he doesn?t think time travel is a possibility, ?Definitely not within our lifetimes.?
