In my blog I am posting a series on "How to Make a Universe" and so far have done parts 1 and 2.

These discuss the background of physics and some repercussions of that. The ideas are not mainstream, but agree with everything except the big bang bung theory. My background is in cycles study and cycles are found in everything. Cycles are a natural part of the universe resulting from standing wave oscillations which have existed for a time far longer than the wee blink considered in big bang bung.

The series is leading to a description of why the universe has the structure that it does by which I mean galaxies, stars, planets through to atoms and nuclei and all their relative scales. All this is predicted from a single axiom that follows logically from standard physics.
