Model of the Universe/Multiverse

[Tree Universe]

Hi Everyone,

One of Hawking's last publications studied the model of universe/multiverse and conjectured that the exit from eternal inflation is "finite and reasonably smooth" - in other words, the inflated boundaries of multiverses could be finite and smooth. Here is the paper link - https://link.springer.com/article/10.1007/JHEP04(2018)147.

Does any existing model suggest that there are multiverses inflating in infinite space and eventually merging into bigger universes after a long time, just like aerosols growing and merging in the atmosphere? The universe has such a large radius that it could flatten out like a drop.

Uh ... the universe has a radius? Really? What is it? Are we at the center? If not, where IS the center?

Next thing I know you guys will be telling me the radius is 42

In case it isn't obvious from the previous posts, the answer is "no". There are no models that work like this.
