I am not sure if this belongs in General Relativity or Quantum Theory or just General -but here goes. First , I have to say that I do assume Space-Time to be quantized (since anything else seems too difficult!) and this is my question. I have often read that physicists have peered back in time to within a few million(?) light years of the BB and that experiments have been done that recreate conditions within a few milliseconds (?-again) of the Big Bang. If , as I hypothesize, space-time is quantized could these milliseconds correspond to an actual finite number of quantized Space-Time events in such a way that , as we approach the Big Bang (in simulation) we would be able to , in theory, knock off these events one by one until we got to ,say, one space-time event that had been the first ST event immediately after (and prior to -if we are talking about a Big Crunch) the Big Bang? A separate question I have ,if anyone has patience to explain is ,if gravity is accepted to change the fabric of Space-Time why should it be that the other Forces that act on matter don't ? (I am not sure what all the Forces are but I think some are weak and strong nuclear Forces) Excuse my ignorance if that is an obvious question!
