The universe is the web on galaxies.
So simple. Objective observation everywhere and always.
Model needs only some minor changes to GR. Time is not a dimension, no beginning, eternal time. Space 4D, fixed radius, boundless. No expansion, expansion is superficial, not needed at all. Bangs are local.
It is time what is coming more, not matter, not space.
The universe is paradoxically something that is allready rationally in some way, cannot be in the other way.
Kant tried to say something from the solar system on rational base, but that did go wrong. But to say something of the universe rationally, that goes right.
The point, the solution is to make a difference between the whole and the parts.
The universe and the part-universes. The parts begin and move and change, the universe is in some eternal steady state eternally everywhere.
The reality is as it is. Our theories change, they will be better and better.
Science is theories. Science is not physics and mathematics but all sciences and philosophy. Cosmology is philosophy and astronomy together, and all sciences.
