Time Travel discussion

I'm new to the group, and wanted to say hello. Though I wrote a book, and it took many years, I am just beginning to share it. As a newbie in the group, I hope not to make many faux pas. I think there are a bunch of time-bending aspects of The Twin Paradox which are fun to play with intellectually. I really think you guys might get a kick out of it, though it is not directly time travel per se, the science in it more about time compression and relative time flows dislocating events and lives (on earth). I hope you check it out.
