Do Photons Have Mass?
Do Photons Have Mass?
In response to a question on Quora: Some people today have a misconception that photons are tiny little balls; I answered as follows:
You’re implying that the truth is that photon’s are NOT tiny little balls.
I’m saying that they are. Let me explain: just because they’re too small to measure their volume, doesn’t mean that they don’t have a volume; nor does it mean that they don’t have mass. Einstein said that when a light source shines, it loses mass. The usual explanation is that some of the mass was converted into light that escaped from the light source, thus reducing its mass. I can argue that the missing mass is within the photons which implies that photons are particles with the mass that was in the light source.
Einstein also said that when an object absorbs light, it gains in mass. Again, the usual explanation is that the energy of the light was converted into mass. Einstein said that energy and mass are different sides of the same coin i.e. no conversion takes place. This corroborates the fact that there’s mass in the photon. Besides, Einstein said that pure energy will curve spacetime giving rise to gravity. I can say that it’s the mass in the photons that gave rise to the gravity.
If you think of photons is composed of equal numbers of oppositely charged particles, they will generate the electric field component; and their movement will generate the magnetic field component; thus the photon will have the electromagnetic property. The charged particles means that the photon is itself a composite particle.
Louis de Broglie postulated that moving particles with mass will display wave properties; and this was proved with electrons instead of photons in the double-slit experiment. The conclusion is that the photon is a particle with mass that displays wave properties i.e. the Particle-Wave Duality theory is false because the photon or electron is a particle and a wave at the same time.
To understand this, consider a static electric charge – it generates an electric field around itself. If that charge moves, it also generates a magnetic field around itself as well. This means that the magnetic field is an emergent property of moving charges. The conclusion is that a photon is a particle and its wave characteristic is an emergent property of moving particles. See the similarity? Perhaps de Broglie’s wavelength can e explained in terms of electromagnetism.
Believe it or not, I haven’t introduced any theory of my own; I simply put 2 and 2 together. These theories that I put together are already established and accepted.
So the conclusion is that light is a stream of particles which are tiny little balls. This means that the people who think like that, are right. It’s your perception that’s wrong. You didn’t come up with that on your own, did you? Of course, not. You’ve been taught that by people who also got the wrong end of the stick.
Just remember that there’s a Crisis in Cosmology because of a plethora of false theories that are taught in High Schools and Universities; which end up in serious fields like Cosmology bringing it down while they were at it – and are still doing it.
