Does the many worlds interpretation of quantum mechanics presage the existence of anti universes where for every matter particle there is a anti particle?

 

Also do these projected universes support inversion of symmetry.

 

eg) My anti self in my anti universe would raise his left hand when i raised my right hand. (Quirky... )

 

Please provide some insight into this issue.

"Many worlds interpretation" is more an Internet phenomenon than real science, afaik. Anyways: Considering that "and suddenly every matter particle has turned into an anti-matter particle" is not a possible solution for time development in quantum mechanics I would dare saying the answer is "no".
