Well gentlemen (and I use the word loosely) it appears that I'll never have the slightest clue on this question because the explanation in layman's terms is completely wrong. My math is limited to 2 + 2 can equal 5 if the value of two is large enough.
Accept it from those who know? The last time I did that I lived with a lie for 65 years (as have all of you) but that's off topic. I'll call this one closed because it's dead-ended for me. Thanks for trying.
Yours is a common dilemma. If you cannot or will not learn the required mathematics to study modern physics as an undergraduate student would, then you do have to accept explanations without fully understanding them.
The purpose of this site is to provide the next level of understanding, where possible, beyond popular science. If you are happy with what popular science tells you, then fine. But, it is a deadend. It doesn't allow you to think for yourself beyond what you have been told.
If you study physics as an academic subject, then you have the tools to explore the subject for yourself. Many people who read popular science are unhappy at this situation. But, the physics students puts in hundreds of hours of study to learn the subject. And, from the very start is required to solve problems for themselves and apply what they have learned. The popular science reader learns passively, and is never asked to roll their sleeves us and spend hours solving problems for themselves.
You can be as skeptical of this state of affairs as you like, but there it is.
One final point. The question of whether space is physically stretched is at best superficial. You're getting absorbed by a question that is ultimately of no relevance. There is a huge body of knowldege in the realms of GR and Cosmology. To me, that's what's sad. There is so much to learn in modern physics, but you've ended up foundering on a question that isn't even a question that physicsts are concerned with. You haven't even scratched the surface of what there is to learn about Cosmology, but have been stopped in your tracks by an irrelevant concern.
That we do not share your concerns is not our problem. That's your problem and prevents you from learning further.
