Not according to a theory proposed by Steinhardt and Turok. The Big Bang is an intermediate event according to their theory.

Please see: http://en.wikipedia.org/wiki/Ekpyrotic_universe

At this juncture their theory makes exactly the same prediction as the B.B. modified by Guth's hypothesis of early extra luminal expansion.

I'm up for any theories submitted by dinosaur hunters.

The Big Bang was merely an expansion of something. It wasn't nothing. It was something that changed its state. There was something before the Big Bang, and that something expanded. Nature abhors a vaccum.

James Vega: Hey, I just like dinosaurs.

@ruveyn: But have the current cyclical models found a consistent way to deal with the thermodynamic prediction of the heat death of the universe?

Yes, in the Turok-Steinhart model, the branes would collide again and cause another Big Bang, creating another expanding universe in the next cycle with it's own matter etc. There is a net expansion in each cycle that prevents the entropy from building up, so the cycles can continue indefinitely.

Tu Shun 557-640 B.C.E. Indra's Net of Jewels
Envision a large net that:
*At each juncture there is a jewel
*Each jewel reflects all the other jewels in this cosmic matrix
*Every jewel represents an individual life form,atom,cell,or unit of consciousness
*Each jewel,in turn,is intrinsically and intimately connected to all the others
*Thus,a change in one gem is reflected in all the others
