Ok, so once again i was watching an episode of The Universe, Unexplained; and one of the questions that came up was time travel.

I guess there is a guy thats trying to make a small time travel device that can send photons or small atoms through time. The way he explained time travel and his opinions on it seemed logical in my eyes, so i'm leaning more toward agreeing with him. He stated that you can only travel back in time to the day you invented a time machine. If you go back any farther, the time machine wouldn't of been invented it.

And to disprove that grandfather paradox, he suggests parallel universes so when you go back in time, it might not be the universe that you're accustomed too. Everything might be almost identical but its not "your" universe so when you kill your grandfather, he dies but nothing happens to you.

So i think time travel is a possibility in the future. I'm just not sure how scientists will use it.
