Jason;

No worries .. now I get ya. Thanks for adding more text.

The following information may clarify some Standard Model concepts ..

According to the Standard Cosmology Model (SCM), ‘The Big Bang’ has been postulated as an extremely rapid expansion of everything, all at once, in every direction. ‘It is an intrinsic expansion—that is, it is defined by the relative separation of parts of the early universe, and not by motion "outward" into pre-existing space. (In other words, the universe is not expanding "into" anything outside of itself).’

The explosion analogy is not the same concept as the Big Bang. An explosion moves into a pre-existing medium. It is postulated in the SC Model that, perhaps, space-time itself did not even exist prior to the Bang.

‘The small variations in the Cosmic Microwave Background Radiation (CMBR) we see today are due to temperature differences in the environment in which the photons existed at the time of recombination’ (ie: when the universe was roughly 380,000 years old – ie: after the Big Bang). ‘The cooler regions of the CMBR are where matter was ultimately able to form, from this time onwards.
A smaller variation in the CMBR is believed to have been caused by the effect of gravitational waves caused by Inflation’. There are other theories about other minor fluctuations in today’s CMBR.

Cheers
