Well, things like, in cyclic theory, we have branes moving about, and when they initially touch, it starts the bang of the biggest sort.
The models I've seen for it show a fair cycle pattern, that being a sort of double ellipse, where we have more than one brane moving in opposite directions.
This model I saw had a great gaping hole in the center, the only graphical interpretation I can include would be this:
________
|...<...|
|.|^^|.|
|.|...|.|
|.|...|.|
|.|___|.|
|...>...|
^^^^^^
The Branes would be represented by the >'s or <'s, the dots are just so the picture works in ASCIIart. Anyway, I thought it was sheerly pointless to have the big space in the middle, so the first thing I did was change it to this:
____
|.<.|
|.|.|
|.>.|
^^^
And you'll have to forgive me, I mean for the center to be a point, not a line, but if you'll take my literary description as an aid:
I picture a cylinder, one where a brane would extend from the center to the edge, and the outer edge of the brane would slide around the edge of the cylinder. In this way, you would retain the startoff collision, but eliminate the massive void in the 'center'.
Next, I threw entropy in on a universal scale, rather than just stopping with the universes hitting each other, let's take a look at a possible start to it.
If we began with a single humongous brane, that curled throughout the surrounding cylinder, it, through eventual loss of energy, can no longer support its own existence, and attempts to break into 2 branes, the surrounding existence has energy floating around in it, but it doesn't have quite enough for 2 large branes. The initial attempted break up introduces a lot of energy, and almost gets it there, but the two smaller branes can't quite be supported, so they form into another single brane, smaller than the original, and less filled with matter and energy, but still overall giant. This also loses energy, up until it just needs to break apart. It's smaller size and the overall greater amount of energy present now than the inital breakup allows it to form 2 smaller branes. Next up, these two branes collide, creating a material universe and an exiting brane, the material universe loses energy and breaks apart after it expands for an extremely long time, and it breaks into 2, bringing our total to 3 branes, then more collisions, BB's, and expansions, and we have 5, more, 8, more, 13, each time with smaller overall branes being formed.
I'm betting that it follows the Fibonnaci sequence, as you can see from my initial 1,1,2,3,5,8.
Next, what would make more sense for a big bang than a massively powerful white hole? When the branes initially collide, I believe this is what would cause a white hole. Then, the branes attempt to mix as they pull through each other, and as they pull away, the connection extends and energy falls into it without the possibility of coming back- a black hole! This would constitute an early universe filled with micro white holes, then with micro black holes, eliminating a lot of the excess matter, and the black holes would evaporate as the branes got farther away from one another, since a black hole would exist in each brane, and matter/energy would go into the black hole, so it would introduce more energy into the outer area, allowing for more branes overall, it works out!
On another note, the amount and size of branes could be comparable to an analog signature, an energetic vibration. Line up millions of these cylinders in a row, and you get what could be seen as, Strings! These make up quarks, and it goes up the ladder to branes again forming new string-bits. There's even a number of ways to look at it that from the number of universes inside the brane, to those the actual brane moved through, to those the cylinder moved through, with time included, would be 10 or 11 universes.
These have been my epiphanies, I hope I've done them justice in my expanations!
