jamey2k9 Posted February 1, 2009 Share Posted February 1, 2009 before the big bang what was there if the big bang started time and space then what was before that because there had to be something to contain the big bang in the first place but what was it Link to comment Share on other sites More sharing options...
Klaynos Posted February 1, 2009 Share Posted February 1, 2009 We don't know. There are some ideas that are around atm, but we don't know. Link to comment Share on other sites More sharing options...

Martin Posted February 2, 2009 Share Posted February 2, 2009 before the big bang what was there if the big bang started time and space then what was before that because there had to be something to contain the big bang in the first place but what was it Big bang theory does not say that the big bang started time and space. Scientifically there is no reason to assume that it did. Models currently studied go back before and there is plenty of time and space and energy as usual, just in a contracting mode.

Martin Posted February 2, 2009 Share Posted February 2, 2009 (edited) thanks Martin An Interesting Approach no problem, kürt. Just pointing out the obvious---the older bigbang model doesn't go back to any instant of time you can call the beginning. It only starts to apply when the universe is already expanding, before that at time t=0 so to speak it experiences failure and doesn't compute. So the older model simply does not describe a beginning. I think you are familiar with this---we've discussed it several times here at SFN. The newer models do not experience failure---do not have a singularity where things blow up---and continue on back to times before t=0. So basically you can take your choice: NEITHER ONE says that space and time had a beginning at t=0. One way to track the changes in how the experts are thinking is to look at the list of topics at the big international GR and cosmology conferences. This year will be the MG12 meeting in Paris http://www.icra.it/MG/mg12/en/parallel_session.htm You can see that nonsingular cosmology and quantum cosmology are featured in the parallel sessions. Section D: COT-3 and COT-4 Even more relevant will be the program at GR19, in 2010. http://www.gr19.com/index.php These meetings happen once every 3 years. GR19 hasn't posted much yet.

devrimci_kürt Posted February 3, 2009 Share Posted February 3, 2009 well The Universe = Space and Time ??? right or wrong? Link to comment Share on other sites More sharing options...
Martin Posted February 3, 2009 Share Posted February 3, 2009 wellThe Universe = Space and Time ??? right or wrong? I would say right. Include matter as well, why not? Link to comment Share on other sites More sharing options...

Airbrush Posted February 3, 2009 Share Posted February 3, 2009 wellThe Universe = Space and Time ??? right or wrong? Our visible universe is not necessarily ALL space and time. There could be others very far away, or hidden in higher dimensions. Anywhere there is matter, then there is space-time. Even the great empty voids between superclusters have some atoms, about one hydrogen atom per cubic meter. Our universe (our space-time) may be only a local phenomena. There may be other space-time universes quadrillions of light years away. Where there is no matter there is only space, not space-time. Space-time requires matter. I just made this up, but it seems logical to me. Link to comment Share on other sites More sharing options...
