Beschreibung

The central drive in physics recently is to fuse the two main theories, quantum theory and relativity. Both are well tested, but among the things they disagree about is time. That means two different notions of time must now somehow be reconciled - it has brought to the surface long-standing contradictions about time, and some now see time as the main obstacle in attempts to reach quantum gravity. So a puzzle that for decades was set to one side has shifted from the edge to the centre, and become a key [...] interesting part of the puzzle is the contradiction between the two main theories about whether the future exists yet. Quantum theory tells us the future is unformed and undecided, because of a deep-seated randomness about events at the particle scale. But special relativity has led to the idea that the entire future already exists, and is unalterable. Both theories are well tested - the mathematics of both is certainly right. But it seems our understanding of at least one of them must be wrong [...] of the clues to the time mystery are so weird that people hardly talked about them until recently, and now new clues are being found. The standard view of time, in as far as there is one (there's little consensus on any of the issues), has been failing in laboratories since [...] things we know for sure don't fit with any view of time. We know matter gets out of sync with other matter - constantly, everywhere. Across the wide universe, dust grains that move differently for a few microseconds age at slightly different rates, and are left with permanent age differences. This is from basic special relativity, and has been measured, but it doesn't fit with the standard view of time, and nor do some of the other [...] aim of this book is to set out more of the puzzle than has been set out before. The book is for both popular science readers and physicists. It explains the main clues - including rarely mentioned ones - with an engaging frankness, also the avenues of thoug
