Baryonic Matter Abundance in the Framework of MONG

Abstract

It is well established from various pieces of observational evidence that the relative abundance of baryonic matter in the Universe is less than 5%. The remaining 95% is made up of dark matter (DM) and dark energy. In view of the negative results from dark matter detection experiments running for several years, we had earlier proposed alternate models (which do not require DM) by postulating a minimal field strength (analogous to minimal curvature) and a minimal acceleration. These postulates led to the Modification of Newtonian Dynamics (MOND) and Modification of Newtonian Gravity (MONG), respectively. Some of the independent results that support the existence of non-baryonic matter are the mass–radius relation (that holds true for any gravitationally bound large-scale structure), Eddington luminosity, etc. Here, we discuss how these physical implications can be accounted for from the results of MONG without invoking DM.
