Its not unsolved. It's very solved. It was not an engineering question.
You keep on making assertions - perhaps you could back it up with some explanation of why you regard this as a more fundamental discovery (or however you would like to characterize it)?
That is not engineering. Nobody would call astronomy or cosmology engineering and it is very much the study of "how the universe is built from some basic building blocks.
Don't assign a reductive meaning to engineering that is so encompassing that everything everywhere is engineering, else you render "engineering" a meaningless concept
