- This must be very stupid. If the EM force is via virtual photons,
- how does it have an infinite range, given that a virtual photon
- of frequency 'v' has a non-zero "borrowed" energy 'hv' ?
- Leggett, in his book, "Problems of Physics", says this is because the
- photon has zero rest mass and hence a zero "borrowed" energy. I
- find this fishy.
