    "abstract": "-The favored Big Bang concept is that the original symmetry was skewed, the\nuniverse now being all matter, all antimatter having annihilated.\n  -The mechanism of matter/antimatter annihilation is analyzed. A total\nannihilation of original antimatter could not have occurred; the skewing is\nunnecessary; and the universe must contain equally both forms of matter.\n  -Current detection of cosmic matter/antimatter annihilations is Gamma Ray\nBursts [GRB\u0027s]. However, the conviction that the universe is now all matter\nwith no antimatter has left that possibility rejected and uninvestigated and\nleft standing the massive supernovae core collapse hypothesis for GRB\u0027s.\n  -It has recently been reported that the rate of GRB\u0027s increases with red\nshift z for z = 0 to 4 as (1 + z)^1.5. The indication is that the rate\nincreases significantly with time into the past at least back to z = 4 [and\nprobably back to the Big Bang].\n  -That finding is inconsistent with the massive supernovae core collapse\nhypothesis for GRB\u0027s and supports GRB\u0027s being cosmic matter/antimatter\nannihilations.",
