Good logic.

But the photon whips around a black hole because it is following space around the black hole. I did not know it could happen around a neutron star. Do you have a reference.

But the point is that the super rest mass pbject, neutron star or black hole, creates the distortion of space that bends the photon. The photon itself does not bend space.

For a photon to attract another photon, it would have to bend space. It does not.

Do not confuse the existence of radiation pressure with mass momentum. Radiation pressure can be calculated from Maxwell's equations alone, and there is no mass in Maxwell's equations.

The fact that apparent mass increases with velocity for matter, and is singular at the speed of light, is one more reason why photons cannot have mass, whether it be rest mass or velocity mass. Photons are never at rest from our perspective. They are amazing things. No matter how fast we go, the photons are always faster than us by the amount "c".

Besides all that, if photons had mass, because there are so many of them, the universe would have recollapsed 14 billion years ago and we would not exist. Our existence proves that photons are massless.
