A Glint In Time

I'm thrilled with the way my new novel, "A Glint in Time" came out. Here is the It is true that today, in university labs around the world, graduate students in physics are experimenting with freezing light and time. (Google the phrase Bose-Einstein). My one assumption beyond present science fact in this book is that a new technique gives experimenters the ability to send a small item to be sent back into time. All common laws of physics still apply... the farther back in time the less accurate.. great power is needed.. significant heating is takes place. So, if you could send a tiny white hot object back into time, what COULD you do with it? What WOULD you do with it. And, if you were successful in changing something, how would you know? (The paradox is that if you successfully changed an event, then it never happened, so you didn't need to change it.. so you didn't.)
