Speaking of time travel, The Flash did that in various comics. I also think that time travel would be fascinating if it were for real, since I usually hear Stephen Hawking talk about it most of the time. Hawking may be a non-believer, but his time travel talks make me think of what would I do if I'd go back in time. But sometimes, you gotta leave the past the way it is.
God Bless and Enjoy The Show!
