Time Travel, True or False Options

It's depicted in several movies. Terminator uses technology, The Butterfly effect uses a phychological element, and Superman circles the earth several times to turn back a few minutes to save Lois from an earthquake. Is time travel possible? Magic, technology, speed. What are your thoughts?

I understand your point, detaching or "breaking the tether" that binds the mind to the body, isn't exactly what I had in mind, simply stretch the leash so to speak, into the void that a few on hear have described feeling and reach your future or past self that would be reaching the other way. The key would be to have some way to link your consciousnesses slightly similar to the ways computers do, to exchange information, therefore giving you the same information you would have if you were to have traveled, the next step after that would be more difficult, simply put, while the minds are linked together, stretching them past that point, until both consciousnesses link with the physical body of the other, then trading places. Or so that is a theory, thoughts are appreciated. you would end up in the future with a future you in the past. Which could be both beneficial and a torture if it were to be possible or happen, because you would be able to undo things that you want differently, however any trajedies that may have stuck you, would be relived. again, just some thoughts, hope this clears up a little bit of what I ment with the first post. Criticism is welcome so please let me know what you think.
