TimG Posted February 16, 2009 Report Share Posted February 16, 2009 We understand that the current universe has certain parameters that, if altered to any significant degree, would result in a lack of stars, or a lack of matter at all: Or, a lack of time?

luke warm Posted February 16, 2009 Author Report Share Posted February 16, 2009 well philosophy also concerns itself with physical reality, and logic is necessary for science... Quote Link to comment Share on other sites More sharing options...

helene_t Posted February 17, 2009 Report Share Posted February 17, 2009 I don't remember when I heard this, but I'm under the impression that the universe has continually expanded and contracted and 'big banged' into another version of the universe multiple times, and that we just really don't know about anything from before the last big bang. Did I just imagine that?Or were you there? One speculation that has attracted some interest is that black holes are actually the source of new universes, each with slightly different properties than the 'parent' universe. I gather we both read about this in "The blind watchmaker". Anyway, a google on evolution universe "big bang" "black hole" dawkinsgave a.o. http://www.mkzdk.org/twitcher/cosmos.htmlNot sure how serious this theory is taken by cosmologists. Sounds cute, though :P Quote Link to comment Share on other sites More sharing options...
