If I understand this correctly:

In the main Cosmic Inflation universe, new space is created exponentially with time.

In roughly 1 out of every 30,000 pieces of "new space", a big bang occurs from a random quantum fluctuation. The big bangs slow down the inflation expansion in a local area that becomes the equivalent of a 'pocket universe'.

There was perhaps an infinite number of big bangs (and dead pocket universes) in the past, and there will be an infinite number of big bangs (and new pocket universes) in the future.

the ultimate run-away train! No matter how impossibly big it is, it just grew infinitely bigger in the past second.

Yes. The Cosmic Inflation universe grows exponentially bigger every tiny fraction of a second. And this has been going on for possibly billions or trillions of years or longer. The number of big bangs and pocket universes created by that is mind boggling.

The first of 31 articles- I look forward to this series!

Yeah. Can't wait for more!

I hope this comment is allowed, because the title was confusing to me - I thought this was a new economic term, like hyperinflation.
