I didn’t think a topic about time-travel paradoxes I started would provoke so many replies! I wrote a book about my interest in time which is titled “Hope to time-travel”. For those interested I’m willing to e-mail softcopies for free. Just email:[email protected] (requesting a copy). I advertised my book in the Time Travel Institute Discussion Forum along with other places. I’d be grateful if you could send feedback, but you don’t have to.
