here's another idea for the pre-big bang theory--- the universe in a low entropy area of a higher dimensional space, sometimes conceived of as a black hole sea

I heard a pre-big bang theory that the big bang was an effect created by an area of low entropy in a "black hole sea". the area low entropy created the observable universe, and allowed for normal energy reactions like vaccuum perturbations to occur at every point in space, and I think that violations of cp-symmetry would allow for matter to overcome anti-matter. this theory is a little too wierd for me to actually believe in but it makes a little more sense than like....m-brane collisions

anyways I dunno what OP is getting at but here's some more pre big bang theories http://universe-review.ca/F02-cosmicbg.htm#prebigbang

Okay this is just like "free association"

One pre-big bang thoery I heard of was an idea that the universe formed out of a low entropy zone in a "black hole sea". This is one of the weirder pre-big bang theories that i've heard, but it sort of fits some other hypotheses I think. I guess the low-entropy would allow for energy reactions like vaccuum fluctuations. I read in a textbook "cosmos" that during the big bang, the whole universe would have so much energy that pair production would have occured at virtually every point in space. I think this is interesting because there is evidence that cp-symmetry can be violated, which I take to imply the creation of more matter than anti-matter, and if I interpret a youtube video correctly http://www.youtube.com/watch?v=kXy5EvYu3fw the they mention that the violation is, to put it loosely, because of magnetic vortexes?

That's sort of a consistent idea, but it doesn't seem like it has any weird implications. I guess the image says that primordial black holes could be evidence of this black hole sea thing
