Is Time Travel Possible?

Maybe it's my scifi/fiction writing past but I've always thought that time travel is a possibility someday.
Perhaps it's that the universe/laws of physics prevents physical, solid matter from moving through time. In the far future we may discover a way to send pure energy - aka our pure consciousness - through time, allowing one to witness history as a sort of ghost (sort of time travel telepresence). This would prevent someone from affecting the timeline because no direct interaction would be possible as well.

No. The past and future do not exist except as ideas. The only time is 'now'.
As for time travel into the past... pretty much no. That would have a bunch of really disturbing consequences, including traveling faster than the speed of light and violating the second law of thermodynamics.
Of course, this just a former physics minor on stupid macro affects. When you get down to the quantum particle level the game probably changes considerably.
