I found the information

Good questions. Honestly, I don't have the answers for you. I
remember that the concept intrigued me when I read it a while back,
and now I plan on reading it again and thinking about what the
author has written. I'll keep your questions in the forefront of my
mind. I've only had two years of univ. physics and that was a number
of years ago, so even after I've digested this material I may not be
in a position to properly answer your questions. Others on the list
might though, and I'd be very interested in what people have to say
about this matter.
