This might be an interesting book, but you have to have a more thorough knowledge of physics. So, by rating as I did, I am not dismissing the book, but rather badly my lack of insight for missing out so much of what could possibly be a really great book. ( ) This one adopts the point of view of loop quantum gravity, an in-progress approach to reconciling general relativity with quantum physics. Less ballyhooed than string theory, it differs from the latter in that it posits that space and time themselves are quantized (discretized). Having a smallest possible time interval (probably ~10^(-42) sec) implies there is a largest possible energy density, and this would enable the troublesome theoretical singularities in black holes and at the Big Bang to be avoided. Pre-Bang times would exist and cyclicity of the universe would be a possibility. A good, fresh contribution. geen besprekingen | voeg een bespreking toe
In 2000, Martin Bojowald, then a twenty-seven-year-old postdoc at Pennsylvania State University, used a relatively new theory called loop quantum gravity--a combination of Einstein's theory of gravity and quantum mechanics--to create a simple model of the universe. Loop quantum cosmology, or LQC, was born, and with it, a theory that managed to do something even Einstein's theory of relativity had failed to do--illuminate the birth of the universe...
