- I can see you've sweated blood over this problem. Maybe since the products
- of e+ e- annihilation are two or three gamma ray photons, the mass of the
- pair becomes the mass of the photons. Does that seem unreasonable?

- Well, I never knew that - thank you for explaining. :-)

-
- My claim was that Bondi had said "Energy has mass" and that energy and mass
- are not interconvertible. My reference provides authentication of that claim.
- It's hardly my fault if the University of California, or wherever, chucks
- out its copies of Physics Bulletin to preserve valuable space for toilet paper.

-
- For a start, have you looked up the other references I gave? If not, perhaps
- *you* could explain to us, in the mean time, where the mass of the positron-
- electron pair goes in annihilation. I'd be interested in proceeding with this
- discussion and willing to go into more detail, by all means, but at the
- moment your tone seems a little too aggressive to be conducive. If you are
- genuinely interested, please say so, and also say what your understanding of
- the subject is, so I can put you straight more easily.
