A Model of Modified Newtonian Gravity Alternative to MOND, Consistent with the Properties of Spiral Galaxies and Compatible with Extragalactic Dark Matter

A new model of the modified Newtonian gravity called Compacted & Collapsing Gravity (CCG) is proposed. Similar to Milgrom’s MOND, it allows explaining flattening rotation curve in spiral galaxies, thus eliminates need for dark matter at this level. However, contrast puts a distinct limit on effective gravity; thereby constraints sizes single galaxies connection their masses, which complies with observations. In bigger than structures such as galaxy clusters, CCG rather complements replaces interpretations observational data based matter. Besides, provides plausible explanation hierarchical structure universe.
