The relativistic mass formula isn’t valid for photons, so the 0/0 is a misuse of the equation. Photons have zero rest mass but nonzero energy and momentum, which is enough to explain radiation pressure and experiments like Nichols radiometer. Modern physics consistently works with energy-momentum, not moving mass — and this framework has been tested to extraordinary precision. The ‘quantum mechanics battle’ idea isn’t supported by physics.

If you use the full formula E=(p2c2+m2c4)1/2 and insert m=0, you get E=pc. Then insert the de broglie wavelength p=h/lambda and you have E=hc/lambda=hv.

Looks quite self-consistent to me and doesn't require divisions by 0.

Why Poynting's Theorem P = Ex H is. Quite Valid for DC Circuits Dr. Ismail Abbas ... happens in the physical phenomena of Compton scattering [5.] I, Abbas ..This means that the photon has a finite lifetime (never 10E10 years) and has a finite moving mass that can dissociate.

"The rest mass of a photon, m0=0, is generally accepted."

What is a photon at rest? That's the big question!

According to common sense, or better said, according to logic, there are no photons at rest! So the concept of "rest mass of a photon, m0 = 0" is nonsense.

The answer to “Does a photon have moving mass?”, if it would be more scientific as “Does a photon have inertial mass?”, is: photons are particles, and so fundamentally obligatorily have inerftial masses, m; besides photons, again since are particles, so fundamentally obligatorily have gravitational masses, values of which, rather probably, are equal to m.

At that , as that rigorously scientifically rationally shown in the Shevchenko-Tokarevsky’s Planck scale informational physical model, more see https://www.researchgate.net/publication/391209088_The_Informational_Conception_and_Basic_Physics, the ultimate and utmost universal base of Matter is the [5]4D dense lattice of primary elementary logical structures – binary reversible fundamental logical elements [FLE] that have [5]4 utmost universal – “kinematical” degreases of freedom at changing its state – “FLE binary flip”, and everything in Matter is/are some specific disturbances in the lattice. The lattice is placed in the correspondingMatter’s [utmost universal] fundamentally absolute, fundamentally flat, fundamentally continuous, and fundamentally “Cartesian”, [5]4D spacetime with metrics (cτ,X,Y,Z,ct), where cτ,X,Y,Z, are 4 space dimensions, ct is the time dimension. FLE “size” and “FLE binary flip time” are Planck length, lP, and Planck time, tP,

- so everything in Matter is/are constantly and always movong in the lattice/4D space only with the speed that is determined by FLEs – “the speed of light” c= lP/ tP.

The disturbances “particles” are created if some the lattice FLE is impacted with transmission to it some momentum and energy, what causes in the lattice, and so in the 4D space, sequential cyclic FLE-by-FLE flipping along the 4D helix –and so by this way particle exists always at every time moment as “particle-point” that has ~ lP size, momentum P=mc, [“bold” means 4D vector], m is inertial mass, energy E=Pc=mc2,while this point is on the helix that has radius, r. If particle is at rest in 3DXYZ space, r is equal to the particle’s Compton length λ= ћ/P0= ћ/m0c, m0 is the particle’s rest mass

If having rest mass particle is impacted also by some 3DXYZ momentum, p, it moves also in this space, and the helix is observed as de Brogile wave; having by Pythagoras theorem 4D momentum P=(P02+p2)1/2; if a particle is created by 3DXYZ P momentum, it doesn’t move in cτ-dimension and moves only in 3D space with the speed of light, now that are known photons, but E=Pc=mc2 remains.
