The Fabric of the Cosmos
- Space, Time, and the Texture of Reality
- By: Brian Greene
- Narrated by: Michael Prichard
- Length: 22 hrs and 16 mins
Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past?

Quantum Physics For Dummies!
This book finally makes quantum physics understandable (as much as anyone is truly capable of understanding quantum physics) and even enjoyable. Coming from me, this is quite a statement. I have a shelf full of books promising to explain quantum physics in simplified terms. I think I made it to chapter 3 in one of them. The author begins by taking the reader back to the basic science class of yesteryear, and giving a review of Newtonian and Einsteinian physics. Even though this is for the benefit of those with absolutely no background science, there are enough new little tidbits sprinkled in, that weren?t covered in those classes, to give the average individual a few ?Hmmm, I don?t remember hearing that before? moments. Greene moves on to sub-atomic particles and explains how light is both a wave and a particle. The reader can finally understand these concepts because many fascinating experiments are described and explained. Just about the time when you think you?re getting lost, he backs up and relates what you?ve just learned to what you knew (or thought you knew) before. After showing you how to process this new information by taking you backwards a few steps, he gently moves you forward again. He explains how observing a particle in any way, changes it. I had heard this, too, but my interpretation was, of course, much, much too simplistic. Three steps forward, one step back. He slowly pushes your capacity to question the most basic assumptions about life. He goes into ?Time?s Arrow?. If we can remember the past ? why can?t we remember the future? Mathematically we should be able to. Can our actions NOW effect the PAST? It certainly appears that they do. And it is all explained, bit-by-bit, piece-by-piece. Schrodinger?s Cat is explained! It has to do with probability waves, their collapse, and the ?light is a wave and a particle? thing - or so one of the current theories goes.Then again there's that multiple dimension theory. And string theory. And the . . .
