An amount of well-founded speculation exists to the effect that the process of rapid expansion which drove the early formation of the Universe we see in fact never stopped, and new regions of spacetime which look like Universes from the inside are constantly being produced. The technical term is <I>eternal inflation.</I> A decent introduction to the subject is available <A HREF="http://blogs.discovermagazine.com/cosmicvariance/2007/04/27/how-did-the-universe-start/" REL="nofollow">at Cosmic Variance</A>.Blake Staceyhttps://www.blogger.com/profile/13977394981287067289noreply@blogger.comtag:blogger.com,1999:blog-6851578517872251953.post-20917034735326789282008-12-13T23:42:00.000-08:002008-12-13T23:42:00.000-08:00It's a long time since I read A Brief History of T...It's a long time since I read <I>A Brief History of Time</I>, but my recollection was even within sort of "classical" (non-quantum) relativity, he had was a kind of neat way of sort of avoiding singularity in his exposition (I think by using imaginary time, where the singularity becomes a smooth surface). But its been forever since I read it so I may be mixing my recollection up with another work.<BR/><BR/>Besides our universe spawning off from a pre-existing one, I read an introductory paper <A HREF="http://arxiv.org/abs/0812.0177" REL="nofollow">paper</A> just recently that incorporated loop quantum cosmology to arrive at the result that the universe doesn't have a singularity - if it has a big crunch, that bounces into a big bang well before normal physics would start to break down, and looks like it suggests a series of crunch-bang cycles.<BR/><BR/>It seems that there are several plausible singularity-free models that could arise once you start to being in quantum effects.Efriquehttps://www.blogger.com/profile/08526031804261484547noreply@blogger.comtag:blogger.com,1999:blog-6851578517872251953.post-50065670940429260702008-12-13T22:36:00.000-08:002008-12-13T22:36:00.000-08:00Take one big bottle of Coke and add a big bang the...Take one big bottle of Coke and add a big bang theory, a couple of string theories, throw in lots of black holes and shake violently. I'm sure this would be closer to the reality of our known universe although it still would pale in comparison to the infinity version when you take into consideration our little experiment could have been conducted in a bubble of a much bigger bottle of Coke.WWWhttps://www.blogger.com/profile/00199361332202879521noreply@blogger.comtag:blogger.com,1999:blog-6851578517872251953.post-78490512385050986402008-12-13T12:55:00.000-08:002008-12-13T12:55:00.000-08:00When faced by problems like this, it may help to r...When faced by problems like this, it may help to remember how Douglas Adams came up with the idea for the infinite improbability drive...
