Your personal belief that there is a matter-antimatter asymmetry is based on the unspoken conjecture that Einstein special relativity can represent antimatter and, since Einstein does not predict antimatter,m antimatter does not exist according to gurus at Harvard, Princeton & Co. My God!

The sole conjugation for antimatter admitted by Newton, Galileo and Einstein is the sign of the charge. Therefore, their theories have NO serious scientific prediction for antimatter asteroids, stars and galaxies since they are NEUTRAL.

To understand how far reality is from your view, you should read the following paper in print at the American Institute of Physics by Prof. R. M. Santilli (CV: http://www.world-lecture-series.org/santilli-cv)

The Mystery of Detecting Antimatter Asteroids, Stars and galaxies

You should then study the resolution of the basic insufficiencies for antimatter by Newton, Galileo and Einstein in the summary monograph

Isodual Theory of Antimatter with Application to Antigravity,
Grand Unification and the Spacetime Machine,
R.M.Santilli, Springer 2001
http://www.santilli-foundation.org/docs/santilli-79.pdf

and, for numerous specialized papers, you should consult the international conference held in the field

San Marino Workshop on Astrophysics and Cosmology for
Matter and Antimatter September 5 to 9, 2011
http://www.workshops-hadronic-mechanics.org/

A Post Ph. D. Course for ‘serious” studies in antimatter is part of the forthcoming

2012 Seminar Course on Hadronic Mechanics
To be held as part of the International Meeting
CNAAM 2012,
Kos, Greece, 19-25 September 2012
