Do photons have mass? I didn't even know they were Catholic!
To: wolfinator
Not measurable mass. Therefore it doesn’t seem that special relativity is violated. Like another poster has stated, quantum mechanics states that it is possible that the photon was observed in both prisms simultaneously.
Or maybe one of their clocks was off by a millisecond or so.
The real test for this will be reproducibility.

Do photons have mass? No. Photons are Baptists.

Do photons have mass?I'm pretty sure they don't, which makes the E=MC^2 equation irrelevant here. The whole basis for saying that nothing can travel faster than light is assuming that thing has mass.

Do photons have mass?Well, if you want to be particular about it, yes and no.

Do photons have mass?I don't think so. They're Protestant.

“Do photons have mass?”
Yes, but they are very light.

Do photons have mass?
Yes, they have mass.
One must be careful about the language. There seem to be two classes of objects, the ones that can stand still and the ones that can't. One that can (like an apple) has a "rest mass", that is, its mass when it is not moving. Its mass when it is moving will be higher, because of the energy it's carrying (note that this is subjective-- what you think is moving, I may think is standing still). You can give it as much energy as you like, it will get very fast but never reach C. Things like photons cannot stand still, they are always flying around at the speed of light (in whatever medium they're in). Do they have a rest mass? We say that they have a rest mass of zero, that way we can use the same equations to describe both types of object. But a photon in flight has mass, because it has energy. A green photon has a mass of about 4x10^-36 kilograms, about 4 millionths of an electron's rest mass.

Do photons have mass?Only when they stop moving.
