Instead of Big Bang’s initial singularity of “pure” unlimited energy, the Living Cosmos begins with the duality of a single antimatter/matter pair containing the exact Energy/ Mass of today’s cosmos E/M = C². It is based on the principles and conservation laws of the scientific method for the experimental measurement of mass, space, time, and gravity. These particles have always had a total mass of about 10⁸⁰ protons and a total energy of about 10⁶⁷J. The total Energy/Mass = c² of the atoms and photons in the cosmos has always been about c² = E/M = 10⁶⁷J/10⁵⁰kg. The reality of the Living Cosmos begins as a single anti-hydrogen atom sitting at rest in the “center” of a universal void. What makes this anti-atom “alive” is that first it has eternal existence and then relative to the constant size and mass of the positron, the antiproton is slowly growing in size with a proportional decrease in its mass.
