Head's spinning after this one. So I don't know if I could answer any of your questions. Maybe after I read it a few more times, I'll have an iota of understanding.

If you understand, please, add your insights, thank you!

Thanks for posting.

A long and difficult essay, but well worth the time and effort.

I forgot to mention that this is the first explanation of the Big Bang that makes sense to me.

If the "bubbles" are ever-expanding, as is the "bubble" they are in, are they really bubbles or just fringes of space/time/matter where the expansion has already reached?

Small grasp of the concept - perhaps the word "bubble" is just a way to describe something in a more visual manner.

When Hubble’s observations showed conclusively that the Universe was expanding, Einstein abandoned the cosmological constant

Einstein was still alive when Hubble was fixed?
Hubble was flown in 1955?

Very good science writing, which is so notoriously difficult.

I think scientists would be very interested in the “why” if they could get to that point. Unfortunately for them, right now, only God knows.

Thanks for posting!
