I don't think I'd describe it as a "bubble" - but the concept is based on relativity and the inflationary theory:
If I were there at the space/time coordinates of inception when God (the only observer of Creation) made a beginning and I sent you a message on a photon - in the equivalent of one elapsed earth day at my coordinates you would receive it. But from your perspective (if you existed at that time) the message would have taken 8 billion years to get to you.
You would receive the message on the second day at 12 billion years from your coordinates, and so on - up to approximately 15 billion years for 6 days.
For more on this:
(In case you want to know, this exponential rate of expansion has a specific number averaged at 10 to the 12th power. That is in fact the temperature of quark confinement, when matter freezes out of the energy: 10.9 times 10 to the 12th power Kelvin degrees divided by (or the ratio to) the temperature of the universe today, 2.73 degrees. That's the initial ratio which changes exponentially as the universe expands.)
Do you mean sent me a message to where/when earth was being formed from the Inception(where/when God is standing)?
I was asking concerning the observations from God's point of view or from his inception point...what would I have observed from there?
Something of interest...I read of a pecular quality of the obsidian flakes in granite rock. It seems they exhibit a rainbow iridescent pattern to light not found in any otherobsidian(volcanic or artificially man made and cooled in the lab unless exposed to Iridium and flash cooled at the instant of its making). I was trying to to find the linking because I'm sure I'm not explaining the technical details well enough. The point was that the models that predicted a slow cooling of granite over millions of years couldn't account for this iridescent light pattern found in the obsidian flakes in side of granite...it was almost as if the earth was flash made "old" and the shiniy iridescense of granite's obsidian was really a curious photo graph of such an instataneous "creation"...
But hey...I can buy the space time inception idea you speak of...After all the unverse starts with a bang...and time and space are probably warping and not totally constant for the first week or so....it might have taken 6 or 7 (at God's space time inception point) days to calm everything down...by then billions of what we call earth years may have passed to the point that human history's clock starts ticking when Adam and Eve decided they could be like the "gods"..
