Ive been reading about something called asymptotic silence If Ive understood it correctly its state where the 4 dimensions we see today 3 space and 1 time, transform such as there are 4 space dimension and no time dimension. Bee has a post baout this on her blog: http://backreaction.blogspot.co.uk/2014/01/a-moment-of-silence-replaces-big-bang.html but the original paper she mentions is from 2012. On her blog she says that this realizes the no boundary proposal from HAwking and HArtle. However its derived in loop quantum cosmology which predicts a bounce. What I dont understand is that if we lose the time dimension how do we get a prior contracting universe that then bounces? Is the asymptotic silence state only at the moment of transition or...?
