Hey in my opinion, I think it might well be possible. But I have no idea how it would work or when. I have to admit that wiki has a great section on time travel….although it’s a bit long. If you fancy a read: http://en.wikipedia.org/wiki/Time_travel
You should ask some of the quantum / spacey guys, as they might know, but I think that anything is possible! I was reading about space-time, and white holes (again – having given a rather questionable answer to something else, an astrophysicist confirmed that I wasn’t actually making up the existence of a while hole – yay!). Anyway, disappearing into one area of space-time could mean that you could emerge in another area. Or another parallel universe maybe!
To summarise, I would like to say yes. Maybe I watch too much Doctor Who though… I’d make a great companion!
