I would like to hear more about anti-neutrons in a followup show. Is it possible to sequester anti-neutrons in a deuterium atom? Or are the processes that hold atoms stable specific to one flavor of matter?

Oh, and while I'm thinking about it, would it be possible to have a particle with 1 1/3rd charge by combining quarks and anti-quarks?

And while we are on the subject of atomic nuclei, what effects do we expect to see of neutron stars as an environment where the strong and weak forces dominate over the electromagnetic force?
