Not in the Big Whisper model. It is near identical to the Big Bang model (named after Penzias and Wilson who discovered the whisper of the materialization process).

The Big Bang model is a Cyclops; it contains an aspect in which all is one somehow.

It's A --> B

The Big Whisper model is different (before reaching the CMBR that is).

It's A --> A' --> B

--

Everyone knows that the omelet cannot exist unless the egg got broken.

Somehow, physicists do not apply that to the materialization process of 13.8 billion years ago.

They say we live in the result, but they don't acknowledge that the prior egg was broken.

The difference?

The atoms formed at the CMBR, and this is NOT 380,000 years after the initial start up. The start up occurred not all that far from the CMBR. The atoms started up relatively quickly, and their source was not from the center.

No egg breaks from the center, ever, never, ever.

If we want to understand how A --> A' --> B, then we must look at B and reverse the motion.

The outbound motion of B declares the inbound motion at the end of A becoming A'.

Inbound motions? You betya that egg got broken with that inbound motion that did not stop. It broke, sooner or later, but most certainly a fact.

And, No, it did not break in its perfect center -- that is physically impossible.

We live in a result, right? Then it got broken, whatever we wanna call it.

Three minute read to declare more or less the same:

"The flaw in the Big Bang model."
