Cosmology and Physics: The Deepest Mysteries

 I am a non-mathematician and my knowledge of physics, apart from average high-school basics, comes from 45 years of reading popular accounts by eminent physicists and cosmologists.
My past professional activity, worlds apart from general relativity and quantum mechanics, was in food science and technology.

Yet, in studying the history of natural sciences I found evidence that important philosophical contributions have been made both by amateurs and by researchers active in unrelated fields. It may even be that escape from a blind alley actually benefits from views generated by outsiders, including those lacking formal mathematical education.
In a scientific world of ever increasing specialisation, where old-fashioned allrounders, knowing little of many disciplines have all but disappeared, many a sorely needed impulse may well come more from synopsis than insight.

I see this as my chance, believing that the ideas and questions issuing from this basis deserve the scrutiny of professional physicists and cosmologists.
Some of these thoughts have never been published or presented by professionals.

I hope to get answers and open discussions in the form of this "electronic poster session".
