Really? I am going to have to see that one to believe it (not saying it
is incorrect though), a "something" with no mass--kinda like a "ghost
particle!"
You see it every day; it is called light.
Photons are not particles because they have no rest mass; particles
by definition do.
If photons had mass, they couldn't travel at the speed of light.
Or didn't you know that nothing with mass can travel at the speed of
light?
