Cosmological Consequences of a Quantum Theory of Mass and Gravity

The understanding of several cosmological problems that has been obtained from the development of the Generation Model (GM) of particle physics is presented. The GM is presented as a viable simpler alternative to the Standard Model (SM). The GM considers the elementary particles of the SM to be composite particles and this substructure leads to new paradigms for both mass and gravity, which in turn lead to an understanding of several cosmological problems: the matter-antimatter asymmetry of the universe, dark matter and dark energy. The GM provides a unified origin of mass and the composite nature of the leptons and quarks of the GM leads to a solution of the cosmological matter-antimatter asymmetry problem. The GM also provides a new universal quantum theory of gravity in terms of a residual interaction of a strong color-like interaction, analogous to quantum chromodynamics (QCD). This very weak residual interaction has two important properties: antiscreening and finite range, that provide an understanding of dark matter and dark energy, respectively, in the universe.
