Is the charge coupling constant everywhere is space?

Well, it is a constant related to the optimum spectrum of tiny things, all with the same SNR, becoming congested. So starting out with the question, the first thing to notice is that astrophysicists can measure the coupling constant from stars by looking at the spectra  separation which gives up the congestion of tiny things far away.  But the tiny things must at least be comparable in size to tiny things around these parts, because the physicists instruments that measure the constant are made of tiny things.

So it seems the bubble of the universe are very close to the same size everywhere.  How in the Universe could all these bubbles coordinate their sample rate so well?  I think, or guess really, that over many, many cycles of the universe they have gotten the distribution of Baryons such as to keep the density gradient of bubbles mostly the same everywhere.
