I know what the photon's mass is, but I never talk about it around here because the endless discussion of the photon's mass is boring, boring, boring." Now Master John Baez does not care about the photon's mass. More precisely, Master John Baez does not give a shit about the photon's mass: http://www.edge.org/q2008/q08_5.html Master John Baez: "On the one hand we have the Standard Model, which tries to explain all the forces except gravity, and takes quantum mechanics into account. On the other hand we have General Relativity, which tries to explain gravity, and does not take quantum mechanics into account. Both theories seem to be more or less on the right track but until we somehow fit them together, or completely discard one or both, our picture of the world will be deeply schizophrenic.....I realized I didn't have enough confidence in either theory to engage in these heated debates. I also realized that there were other questions to work on: questions where I could actually tell when I was on the right track, questions where researchers cooperate more and fight less. So, I eventually decided to quit working on quantum gravity." Pentcho Valev pvalev@yahoo.com
