Particle physics and cosmology are mysterious subjects, embracing such strange concepts as ‘dark energy’, ‘braneworlds’ and ‘wormholes’ – terms people may have heard of or perhaps read about, but still don’t really understand. Brian Greene, a leading expert in string theory, has now followed up his earlier, very successful book, The Elegant...
The Fabric of the Cosmos: Space, Time and the Texture of Reality by Brian Greene. Only by accessing the very earliest state of the Universe can we hope to find an explanation for the asymmetry, fundamental to our experience, according to which we only ever perceive time as moving forwards. Physical laws have an inherent symmetry that permits them to operate either forwards or backwards through time; yet we observe all physical processes progressing relentlessly towards an increase in entropy, the gradual degeneration of order.
