TL;DR
Are the values of the universal constants statistically independent of the initial conditions of a bubble universe?
I'm trying to get a somewhat better understanding of the implications of String Theory, eternal inflation, and the multiverse (from a layman's perspective).

I was wondering, which of the following analogies (if either ) would be more suitable for describing how bubble universes are formed and how the values of the universal constants are set, would it be:

1) Like a slot machine, where the slot machine is first built and then the values are set randomly afterwards.

or 2) like a bingo drum, where each ball represents a universe with different values for the constants and each one is drawn randomly?

Hopefully this makes sense to someone.
 
The formal paper is here. The Rutgers University news has published a story about an image being closely examined at their New Brunswick campus. Here is an excerpt: Computer modeling of the gravitational lens by Keeton and Eid showed that the four visible foreground galaxies causing the gravitational bending couldn’t explain the details of the five-image pattern. Only with the addition of a large, invisible mass, in this case, a dark matter halo, could the model match the observations...
