It seems, you don't believe, the Universe is formed by interior of black hole (gravastar be more specific), and the material of this interior forms the space for energy spreading?
BTW Do you believe, the space has density and isn't formed by mass at the same time? Does it mean, the space density is just a mind construct without real meaning?...
Patially inspired by Biocosm banter,
I suspect the stability of the universe is its "survival" factor, or what makes it exist-- and the biproduct is that life can "inhabit" that universe--but the main factor here is the growing of new blackholes, which contain more universes.
Universe A creates Blackholes B1, B2, B3, B4, etc.
Within each black hole is another universe [another A].
Evolution principals of macrolife on earth may also apply to a multiverse creation principal.
The universes that are able to make more black holes--will be "sexually selected"--in that they reproduce more, and become more pronounced.
R is more often distructive then it is good, much like random genetic macromutation(?)
If R is applied to each B [which is a basic replica, but has slight random mutation], and R has a uniqueness factor, general structure of eventual and evolving sub-universes will become more complex and proficient, though they will always hold onto their simple and primary foundations [much like life on earth always reproducing].
At far lower areas of the multiverse,
There are more often instances of exotic matter or energy
that do not behave in a normal and simple way.
Will these more advanced and diverse universes also contain more exotic structure?
Arguably, animate life forms are an exotic structure,
that can exist--built of non-exotic matter or energy.
Life is not exotic matter, it is exotic structure(?)
If exotic structure requires a random and rare event to initiate it [ex: low odds of life evolving on earth]
This means that it needs more oppertunities to "throw the dice"
And this depends on how many planets+stars the universe has.
Size and seed of a universe--the amount of "stuff" it would naturally have in it
Is a pro-reproductive factor of its general structure/existence.
The usual pattern [theoretically] is:
More evolved universes contain more blackholes, kinds of matter, kinds of energy, planets, stars, nebulas, and "physical laws".
Our organic lives may have arisen during a far later stage or era in the multiverse's evolution process
If multiverse evolution is a factor that effects existence of "life" in some area of that universe.
On note of "TimeCube":
Are all blackholes cubable spheres?
Would this mean a universe is ultimately cubable aswel?
Is a sphere always a natural and imperfect shape,
Only produced by evolution
