A thought recently occurred to me regarding cosmological models. Frequently, the Oscillating Universe and one with perpetual expansion are presented as opposing views. This is usually based on the presupposition that an oscillating universe requires a Big Crunch. But in many models of a multibrane cosmos, the Big Bang is thought to have been caused by collision between two membranes, or a near collision in which close proximity triggers a response (through some mechanism I do not understand). Is it not probable that this is exactly what would happen in a continually expanding universe? To illustrate, I will use BEC's as a model (this is what sparked the idea in the first-place). A BEC can be formed by pushing certain particles to a very low energy state. At very low temperatures, the ability to distinguish between these individual particles will vanish and in many ways, they behave as a single particle. If two parallel universes, or two branes of a single multiverse continually expand, their temperatures will continually decrease approaching, but never quite reaching, absolute zero. It may be possible that when the two are at very low energy states, they may attempt to combine into a sort of "cosmological condensate" and that this attempted unification may set up the conditions of close proximity in which the big bang is generated. Are there any current cosmological models matching this description?
