Hardly a satisfactory explanation though, just keep asking "why" and you'll end up with the answer "I don't know why." Unless of course you accept some fundamental state without evidence, which would thereby render every derived concept equally arbitrary. Thankfully however some things (with the exception of their own genesis) aren't contingent upon conception i.e., quantum mechanics (as far as I know). Presumably the Big-Bang theory itself requires the acknowledgement and integrity of such underpinning mechanisms in order to hold any validity. Thusly the parameters for a cyclic model of the universe remain unexplained - the universe itself exists within the mechanism and constitution that defines it, not as an axiomatic construct. You're still left to explain why the apple falls regardless of where it came from.
