I guess I better buy a copy of:

Warped Passages : Unraveling the Mysteries of the Universe’s Hidden Dimensions(Hardcover)
by Lisa Randall

In this easy-to-read volume, MIT’s Lisa Randall takes on the next level of physical inquiry. In the 1970’s, Nobel Prize winner Richard Feynman, a truly fine physicist speculated that we would soon be approaching the physical limits of what we “could possibly know.” He meant that we couldn’t build much bigger telescopes, atom-smashing cyclotrons, or electron microscopes. Our tools for studying the energies in the physical world we hitting walls and there was no good idea on what may lie beyond those walls.

Randall’s book is about what may lie beyond what we understand as “reality.” There may be all kinds of extraordinarily strange forces at play beyond what we can sense. If Randall and her co-theorists are right, they deserve +14 Nobel prizes for divining the true nature of “reality.” If they are wrong, well—GOOD TRY! And maybe a step closer to the truth.
