I think what you're asking is a very complicated and multi-faceted issue.

First, time is simply a human construct. Same as the terms "past", "present", and "future". They refer to our observation of an event relative to another event. So, in reality we are constantly "time traveling" as we are constantly observing events that happen in the present and become the past, so we are moving into the future. Now, the general idea of "time travel" means moving to a certain event marker by will. This is where we have the problem. To perform this feat, we'd have to somehow remove ourselves completely from the space-time continuum. At which point, we'd see all events that have ever happened and will ever happen, all at the same time. This is the main crux of the problem. How can you remove yourself from the space-time continuum? Is there even a "place" to go to that is outside that continuum?

Second, as somebody said earlier in the thread, if you were somehow able to remove yourself from the space-time continuum you'd also have to be able to somehow rejoin that continuum, which more than likely would be done with the same device, meaning that you'd only be able to travel back to the time that device was first turned on.

Third, there becomes the issue of a paradox. If you were able to go back in time and changed something, you'd basically create an alternate future, so when you go back to the time you came from, it'd be different from how you left it in ways you can only imagine.

So, finally, do I think it's possible to time travel? That depends on in which way you mean. In the typical sense of time travel, no, probably not. We might however, if we ever advanced far enough to alter our consciousness and its connection to the space-time continuum we might be able to look at the past or future.
