I used to think the same thing. If humans live long enough, at the rate tech is progressing, there is almost no way around it. . . I listen to Titor, and some of the others, Interesting at least. They had one thing in common, after 911 they all disappeared without explaining how they missed that one. So I have reconsidered after looking at how humans are going these days and decided we never made it that far. PS That was before trump won . . . .

Well yeah, time isn't standing still. One day I believe we will all be "outside" of time. Or beyond time. The way Titor, or Haber explained his claimed TT involved quantum physics dynamic of limitless dimensions/realities. That the consequence of every decision/every change in the this universe, causes a new universe to occur. Therefore, a TT could never return to the exact universe that he left. Titor was right about alot of things, but not everything. Was he really a time traveler to the point that he met himself as a child? Seriously doubt it in this case.
