Standard Model Madness

Fairly even scatter of stars from the centre - all with similar orbits

The Standard Model relies on adding up gravity within a Galaxy or the Universe as a vital part of their evolution. This is necessity over reason - necessity to get the Standard Model to work at any price. Matter like stars associate when close but are almost or totally autonomous over great distance as gravity is near object. Strong associations between objects that is gravitational forms an attractive force which is often conglomerating in nature.
This is amply demonstrated by the Bulge in the Galaxy centre. That contains huge quantities of stars, vast clouds of matter and a gigantic central object as potentially a gravity rich environment. However, that mass cannot add together or the Bulge may collapse. Evidence gravity is not accumulative over great distance in the Bulge, or anywhere else, can be found in the orbit of stars. There is no difference between their orbit close to the Bulge or those further across the Galactic Plan demonstrating no accumulation effect of gravity.
Nether can one Galaxy attract another, even at close quarters, making the Standard Model madness.
