I've been reading about the fascinating phenomenon of a spinning massive black hole having plasma jets (its 'top' and 'bottom'). But before I share with you more about it, can I throw out a thought?

If a positron is like an electron but with opposite spin and opposite charge and is (per Dr. Feynman) like an electron going backwards in time, is there an inherent violation of the speed of light (Special Theory of Relativity) going on here in the case when a positron and a electron collide? Gamma rays are said to for when matter (an electron) and antimatter (a positron) collide... take the case when a Gamma ray 'turns into' a positron and an electron ... at that instance - would it necessitate that the positron come from the future in something akin to traveling faster than light? I've asked this question of several librarians (local public library, university or research lab librarians, and where I work - the librarian there) and have asked some physicists - so far no real answer. I've come to realize that matter/anti-matter particles have CPT invariance - time invariance. It should seem the same whether going forward in time or backward in time. Thanks for reading and please post your earnest responses.
