That was kind of my intuition as well, similarly for time, if there was no distinction between long and short amounts of time, an instant would be the same as eons. If the big bang was improbable but possible it would just happen. The fact that we are here is suggestive that is possible.
It’s a beautiful theory, and I’d like to believe in it, but with ubiquitous virtual particles, the last particle in the universe would never be alone to reject time
I think that's it. Ad a layman I don't understand how the final transition (final hawking radiation) then tells the rest of the universe "I'm done" similar to a sprint retro!
