Someone once described string theory [and its derivitives] as late 21st century physics, that accidently fell into the 20th century...Stephen Hawking?? Still worth considering on that score, and until we have the necessary means to examine and observe at those quantum scales. Sort of the scenario that I was speculating on. Whatever conditions were like at and pre BB, whether fluctuations in the quantum foam, or as you speculate, "chains of Universes", it would control the laws and constants we presently have. For instance, if we look at the quantum foam scenario, some other fluctuations may arise [analogous to a soap bubble in a bath tub] only to burst before it expanded to a size where matter evolved and life evolved from that inert matter.....Other bubbles may have arisen, and be driven to enormous size by conditions, and subsequently again bursting before life can arise. Hmmm, Interesting....I have not actually heard or even envisaged that type of scenario. Why wouldn't any previous Universe's conditions, not influence our one, if that picture is correct. I mean are we not looking at a wormhole type of scenario and ERB? So why would conditions not "flow"through, so to speak? My picture of a singularity, is just a region of space-time, at the quantum-Planck level, that has the smallest volume allowed, and at which GR and the laws of physics do not seem to apply. A singularity is not in itself "Infinite", but "MAY" lead to Infinite quantities. What I'm describing is a physical singularity. A mathematical singularity is a different beast. Agreed. Just some food for thought. Not sure if I read this somewhere, or if it is just my own thoughts on the subject...probably the latter. Please Register or Log in to view the hidden image! The great Fred Hoyle coined the term BB, in a derisive attack on the model. He proposed Steady State. My thoughts on why he was of this frame of mind are that despite being otherwise a top notch scientist, his problem [in my opinion] may have been that the BB model, was leaving the door open for creationists and other God botherer types, in the fact that cosmologists could not explain, and still cannot explain, the whys and hows of that precise moment of the BB itself. They [the God botherers] used that to invoke their deity of choice] Therefor he could not give them that opportunity and along with Bondi and Gold, came up with Steady State. Mainstream science on the other hand, and despite that "opening", but to its credit, accepted the way the evidence pointed to and upheld the scientific methodology despite the obvious forthcoming take from the religious types.
