Negative Matter as Unified Dark Matter and Dark Energy, Distributions of Dark Matter-Energy, and Observed Ways in the Milky Way

Abstract

There are not necessarily dark matter and dark energy in the solar system, and dark energy cannot distribute uniformly in the whole space. Based on Dirac negative energy, Einstein mass-energy relation and principle of equivalence, we proposed the negative matter as the simplest model of unified dark matter and dark energy. All theories are known, only mass includes positive and negative. Because there is repulsion between positive matter and negative matter, so which is invisible dark matter, and repulsion as dark energy. It may explain many phenomena of dark matter and dark energy. We derive that the rotational velocity of galaxy is approximate constant, and an evolutional ratio between total matter and usual matter from 1 to present 11.82 or 7.88. We calculate the accelerated expansion at 9.760 billion years. Further, the mechanism of inflation is origin of positive-negative matters created from nothing, whose expansion is exponential due to strong interactions at small microscopic scales. We propose specifically some possible ways on observe dark matter in the Milky Way. Many observatories should be able to observe these results. Final, we research some basic problems in cosmology: Possible mechanism of missing antimatter, the origins of mass and charge, etc. The negative matter as a candidate of unified dark matter and dark energy is not only the simplest, and is calculable, observable and testable, and may be changed and developed.
