Missing Antimatter

I'm not sure if this should go here, but it is just a specualtion and not a real theory.

 

If antimatter is just normal matter moving backwards in time then at the big bang, or more accurately when matter formed, Particles and their Anti Partlicles would form with the matter partivcles moving forward in tiem and the Anti particle would be moving backwards in time.

 

Any antimatter that did not immediately annihilat with matter would then have traveled back before any matter existed, and therefore would not be annihilated. This antimatter would continue backwards in time. But what would happen after it got to time 0 (the big bang)? Could this antimatter form a reverse time universe that is occureing before the big bang (that might not actually be a sensable question as time did not exist before the big bang)?

It is thought that symmetry was broken in the early universe when charge and parity symmetry was violated (CP-violation). Standard Big Bang cosmology tells us that the universe initially contained equal amounts of matter and antimatter: however particles and antiparticles evolved slightly differently. It was found that a particular heavy unstable particle, which is its own antiparticle, decays slightly more often to positrons (e+) than to electrons (e-).

 

Suppositions of the existence a coeval, antimatter duplicate of this universe are not taken seriously in modern cosmology.

Im thought so, but it seemed a resonable consiquence of antimatter as matter moving backwards in time. Although the Antimatter universe would not nessesarily be of the same physical structure.

 

Take 2 pairs of matter/antimatter particles. If the positron from pair 1 anhialated with electron from pair 2 then the positron from pair 2 travels backwards and will evolve differently to the electron from pair 1. With more particles this would increase the differences between the two universes.

 

But as you said this is not taken seriously, hence why I put it is speculations ;)
