TY - JOUR AU - Alemany, Francisco PavĂ­a AU - Villarroya, Marcelino Alvarez PY - 2021 TI - Gravity, the Origin of the Mass in the Cosmos JF - Physics International VL - 12 IS - 1 DO - 10.3844/pisp.2021.2.10 UR - https://thescipub.com/abstract/pisp.2021.2.10 AB - The most accepted theory for the evolution of the Cosmos is the Big Bang theory, which suggests that, at the beginning, the entire mass-energy of the Cosmos was concentrated within an extremely small, dense and hot singularity. Here, we present a new physical formula that, although obtained in an extremely simple way, has significant implications in Cosmology. This equation indicates that the mass of the Cosmos has grown proportionally with time. This growth equates to a Planck mass for each unit of Planck Time, which is, the mass of 200 000 suns per second. Finally the total energy of the Cosmos is demonstrated to be zero.
