Time travel via wormhole: simple expirement: send out invitations for time travelers to come to a party at your house in an hour. Has anyone arrived? Along with Paradoxes, time travel to the PAST has been disregarded. According to How The Universe Works (by Steven Hawking!), time travel to the past shuts down The wormhole because of radiational feedback, like the screeching sounds at rock concerts. However, time travel to the Future? There are plenty of other ways to move slower through time, though. I suggest you watch How the Universe Works on netflix. Very educational.
no offense but you really just asked that to a bunch of random people on the internet? what did you expect to find: an area 51 scientist who is going to give you top secret government information ON THE INTERNET?
If you watch the show Jessie Ventura conspiracy theory, they did a show on it and had someone from the govt who said yes. The guy had an old picture with president Lincoln from before the civil war that had a kid in it, he said that he was the kid. He said that only small people like kids can get sent. Watch it if you can, it was interesting.
Time travel like in the movies and comics is impossible. End of story. But if you look up at the sky at night, all you can see is the past - thousands and millions of years into the past. The light from distant stars has been travelling at mind-blowing speed for an eternity and has just arrived tonight so you can enjoy it! With a decent sized telescope you can even go back a billion years into the past, but it is too far for you to ever physically go and see for yourself. Which is why time travel is a fallacy for any practical purpose....
