The importance of Light Glare to Galactic Geometry is frequency relationship to ordered patterns of light In the suppermasife realm of universe energy & is as important to the vastness of space as Air is to Earth. The bigger you get the more you reach the relms of energy frameworking & the existance of saturation on sutch a huge scale that in its area is seen as small. The containment of sutch energy on a vast scale of magnitude is akin to the containment of energy of all atoms.

The brightness and the glare of an energy source connects to lightyear distance in the supermassive this dictates the magnitude of its radial diameter. The overall mass of the super massive Galaxy cores which are made up of Light years of Dense Clusters of Collected star material start to affect the environment under gravity. The space in which it occupies changes the space enviroment because of the existence of the (light year density) clusters. Super massive gravity effects in an overall distance of millions of light years is the magnitude of the overall size in which galaxies deal with their environment.
