I was assuming, for the moment, in the Milky Way example. Trying to flow my thoughts best I could. We do not know.
It's difficult for guys, like, me to express thoughts sometimes. Especially in neighborhoods of higher intellects. I understand q & a sessions. No problem there. Not good at citing specific sources or point counterpoints often. Still I try to participate the best I can.
Off topic. Part of my dilemma is 36 years in automotive engineering. An environment where $$$ is everything! Efficiencies matter! Get a machine to operate faster, more parts...less defects...money money money. So most of my brain exercises view the cosmos in similar ways. Hard, if not impossible, to shake my career experiences
I will try to lurk more. Again, I am not on the same science level as others. Likely, I never will be. Not much sense in wasting precious forum time on my low level thoughts. You and me are fine

You seem witty. Keep doing what you do! I will learn a lot from you and countless others. TY for that
