The Problem of Big Bang Matter vs. AntiMatter Symmetry

Authors: Roger Ellman

The Big Bang had to be smoothly spherically symmetrical in its particles, energy, and radiation emitted outward from the origin, and likewise for the emitted particles versus their antiparticles. The result should have been equal amounts of matter and antimatter with the expectation of their complete mutual annihilation. A total annihilation did not take place as evidenced by the universe's existence. The currently favored explanation is that the universe is now all matter, all original antimatter having been annihilated with an equal amount of original matter, the total amount of the original matter having been greater than that of the original antimatter. That is, that the original symmetry was slightly skewed in favor of matter. That conflicts with a purely symmetrical Big Bang and posits a condition, the skewed balance of original matter and antimatter, that is difficult to justify. Current investigations seek to detect an innate violation of matter / antimatter symmetry sufficient to justify the original matter being greater in amount than the original antimatter. An alternative is developed, maintaining the original symmetry yet still resulting in our universe's existence. That involves showing that a total mutual annihilation of equal amounts of original matter and antimatter could not have occurred. The logic and mechanism of mutual annihilation and the conditions for it to take place are analyzed. Our present universe still must contain large amounts of both forms of matter between some particles of which further mutual annihilations still occur at a modest rate.
