The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos
by Brian Greene


"Take any of physics' major theories of the fundamental nature of the universe, extrapolate its math to the logical extreme, and you get some version of a (so far unobservable) parallel universe. And who better to navigate these hypothetical versions of the "multiverse" than Brian Greene?


Normally an unflinching apologist for string theory, the bestselling author of The Elegant Universe and The Fabric of the Cosmos here treats all viable alternate realities to a laudably fair shake. For a book exploring the most far-reaching implications of bleeding-edge mathematics, The Hidden Reality is surprisingly light on math, written as it is "for a broad audience … its only prerequisite the will to persevere."


Such perseverance pays off with a motley cast of potential universes featuring doppelgängers, strings, branes, quantum probabilities, holographs, and simulated worlds. The result is that rare accomplishment in science writing for a popular audience: a volume that explains the science and its consequences while stimulating the imagination of even the uninitiated.  --Jason Kirk"




My comments : What interests me most about this book and books like these is that they demonstrate how very limited our ability to perceive reality is when that reality is not a necessary feature for our continued survival as a species.


We have evolved to know where to obtain food and water, how to protect ourselves against danger, and what makes for the most survival worthy living habitat. Since there is no survival value in knowing what dark matter and dark energy is, we simply can't perceive it. Just like the squirrels in the yard can't perceive what the Dow Jones average is or who Paris Hilton is. Everything seems to operate on a need-to-know basis.
