Can someone look it up. I don't remember if a single photon or a pair of photons is created. If a single photon is created I am not sure how momentum will be conserved with the photon carrying momentum off in one direction. Then there is the Feynman idea of the positon being an electron heading back in time. Lots of fun things to think about.
People forget what happens in a teenager's life.
