Since Hubble's observation in 1929 that the galaxies are moving away from each other at a constant rate which increases uniformly with distance, the concept of a time when all the material of the universe was contained in a single cosmic 'egg' has held sway, i.e., the big bang. The amount of time which has passed since the primeval explosion is estimated on the basis of observed redshift and residual 3 K radiation. It is noted that the expansion has probably been somewhat slowed by gravitational effects from the 3 K radiation, as well as from large resting bodies, i.e., suns and galaxies. Energy densities of photons (10 to the 9th per nucleon) are considered to have been much the same immediately after the big bang as they are now, and after reaching energies of 5 x 10 to the 9th K in the early cosmos, were able to form electron pairs. The formation of electrons is referred to as the lepton era. In the first few microseconds of the big bang, however, temperatures were higher and the formation of hadron pairs (including baryons such as protons and neutrons) was possible. The idea of antimatter becomes relevant at the end of the hadron era. The concept of entire galaxies composed of antimatter is considered to be fully consistent with the mechanisms of particle formation (and eventually the formation of galaxies through variations in particle density) described in the big bang theory.
