Photons have momentum and therefore mass

As mentioned, the momentum of a moving train or a tiny photon particle whizzing along at the speed of light are both calculated the same way: momentum = mass x velocity. One might conclude this: If photons have momentum, they must have mass just like a moving train has mass.

The theoretical momentum of photons with different energies and frequencies can be calculated, and these calculated values can be compared to values determined by experimentation. As explained in previous blogs:

The momentum of photons with different oscillation frequencies has been measured with the use of a torsion balance experiment. In this experiment, photons with a known frequency are directed against mirrors suspended by a tiny wire thread.

Bombarding the mirrors with photons causes the mirrors to move away from the photon beam. This causes the wire to twist as the mirrors rotate in a circle. The amount the wire is twisted is used to calculate the momentum of the photons directed against the mirrors. It was found that the momentum of the photons calculated using the twist on the wire in the torsion balance experiment was exactly the same as the momentum calculated using their theoretical mass and velocity.

Not only can you calculate the mass of a moving photon, but you can prove experimentally that the calculated mass is correct using a torsion balance experiment.

The only logical conclusion is that photons have mass at the time they strike the mirror. How else is it possible for photons to apply a force against the mirrors? I have no idea how scientists who believe in the special theory of relativity can explain this experiment and many other experiments that demonstrate unequivocally that photons have momentum, as well as other characteristics that show a photon in flight has mass.

This is such an important topic that I will continue with it in the next blog or two. Till then be safe and in good health. Kelland—www.vestheory.com
