Thanks for that info re matter and anti-matter not necessarily annihilating each other spontaneously. My thought was that if spontaneous mutual annihilation was the only outcome of a positron and an electron coming together, then how could there be any antimatter left. Surely by now the very small amount of antimatter (relative to matter) left after the BB would have had plenty of time to be annihilated by matter. But now I see why we still have antimatter.
Thanks
Stuart
