The argument for matter-antimatter symmetry in the universe is reviewed. It is found that, based on known physical laws and processes, the universe should be symmetric. In particular there is no known process to create the major elementary particles that does not involve the creation of an equal number of antiparticles. The cosmology of such a universe is discussed without reference to assumed initial conditions or the postulation of new physical laws. In a review of arguments against the existence of large quantities of antimatter it is shown that there is no observational evidence that preclude matter symmetry, in fact it cannot be said whether or not the nearest star is matter or antimatter. The observation of cosmic gamma-ray bursts is also dealt with. It is suggested that these events are the result of matter-antimatter collisions and the case of an anticomet falling into a Koinostar is discussed. It is shown that the mass/energy, collisional frequency, and spatial distribution is in agreement with current observational data.
