Query: Only he could explain Quantum foam like that!

This book was so intense! I couldn't put it down. Just thinking about the concepts in this book make me wonder if anyone is actually trying to do it. I hope they make a movie because it would be amazing! All of the action and tense moments not to be shown up by the pure emotion of the characters! I think it is his best work yet!
