my previous post performed a quantum slip and disappeared.
.....take:deux:
spatial expansion is the result of our visible universe resting upon a balloon-shaped membrane. as this inflates, any given point moves further away from it's neighbor.
the crux is, current models for universal expansion cannot explain the increasing amount of red-shift measured (hence the drive to prove and observe the existance of dark matter/energy). we can see the effect of it's force (increasingly faster expansion), but cannot perceive the cause.
my long-time theory about the Big Bang event is that it is akin to a "white hole". that is, a singularity that has reached a certain critical mass of accretion and then began "dumping" it's meal down one dimensional level in order to maintain homeostasis. the x-rays released via Hawking radiation are not sufficient enough to disperse everything, and it simply adds up. basically, black holes are cosmic bulimics, happily binging and purging away.
that said, I believe that it's possible that other (smaller) white holes exist and are adding new mass by the nano-second, thereby expanding the membrane that we rest on, faster and faster. or, expansion into nearby dimensions is causing a warp effect on our own.
