Gee Pete... they say that there are a couple explanations for that 'problem'...including "inflation".

But that is not what the word 'problem' implies. It just means that many aspects of physics and understanding the Universe are still confusing. The stars and galaxies ARE still out there...and very far apart. *IF* we knew exactly how it all began, we could probably answer how all those distant parts are related. Perhaps someday we shall...but only by using facts, mathematics and observation of phenomena.

We can't 'solve' it by declaring "God just put them there." Most humans are just too curious about the details & processes to be satisfied with a simple answer.

Maybe God started the whole thing running... we shall likely never know that.... but we want to know "what happened after Creation, no matter how Creation happened?"

We already know a lot more than we did 15-20-40-100...years ago, and there are always more questions! It makes it fun!
