I just want to add that I'm totally open to the possibility of Time Travel. I know that it's possible, because years ago I traveled forward in time...1 hour and 10 minutes...quite unexpectedly but it definitely happened.
If there's a real Time Traveler visiting our timeline here and now, I would love to talk to him...but at the same time, I'm going to put his claims to the test, because there's a world full of liars duping people on the Internet.
If one of us went back 100 years in time and told people about the technology we have today, we would not be believed. Many things turn out to be quite possible that were thought impossible. The world is not flat. Mankind can fly. Time Travel is possible. That's what I believe.
