bascule Posted April 18, 2005 Share Posted April 18, 2005 In the cyclical cosmology hypothesized within the framework of M-theory time is still highly asymmetrical. I was wondering if time reversal symmetry had truly shown to be broken experimentally or if there could exist reflection points around which time itself is symmetrical, creating a cyclical cosmology with perfect symmetry in all dimensions.

bascule Posted April 19, 2005 Author Share Posted April 19, 2005 Okay, that was probably a bit hard for people to pick through, so here's an easier way to sum up the question: Has time reversal symmetry been broken? To save yourself some time googling, here are some experiments that claim to have broken time reversal symmetry: http://lfw.pennnet.com/Articles/Article_Display.cfm?Section=ARCHI&Subsection=Display&ARTICLE_ID=199245 http://www.answers.com/topic/t-symmetry (violation of CP-symmetry in kaon decay) http://arxiv.org/abs/chao-dyn/9909005 A fundamentally unresolved asymmetry in time would very much not mesh well with my intuition about the structure of the universe... but a T-symmetry violation is what a lot of people want to pin the imbalance between matter and antimatter in the universe...
