Theos-Talk Archives (November 2000 Message tt00106)

Well, I'm really an outsider (in physics and Theosophy) but I think they
said that photons had no restless mass, I mean, photons couldn't be with
null velocity with respect to any referencial (sorry for my english..)-
just ever the speed of light. That means, at this velocity it has a
mass(?).
Peace and Light,
Pedro
