Time travel has long been a staple of science fiction, but recent research in quantam physics deems it as plausible. There are many arguments on both sides. For the con sides, arguments arise such as the "grandfather" paradox, in which you go back in time and kil lyour grandfather, therefore ever preventing your birth, and the simple fact that time travel in itself is a paradox (an event in history both occured and didn't occur at the same time.) Advocates of time travel believe nature would balance the process by somehow preventing you from killing your grandfather, and see a lot of possibility in wormholes. It's a hard concept to grasp, but what are your thoughts on the subject?
