You have way too much time on your hands, is what I think.
But yeah, on time travel I was watching a show a few weeks ago where a physicist was defending time travel, and how there is nothing in our current knowledge of physics that says time travel is impossible. But the catch is you couldn't go back to the stone age or anything, you could only travel back to the time you or whoever, created the time machine. So if somebody creates a time machine in 2010, and wait until 2011, they could only travel back to 2010. Which, kinda sucks.
He didn't explain all the many, MANY, paradoxes that time travel brings though.
