If photons are entities, are they singularities in the Universe?

Answer 1

Ever since I first studied physics at uni I have personally always hated the assumption made by lots of scientists that singularities exist. A key example stated is that the big bang started with a singularity. I believe that concept to be the sort of nonsense proliforated by pop scientist based on the maths, but not grounded in reality.
More likely is that, as the density of matter increases towards a singularity, new as-yet unknown repulsive forces begin to act which result in the "bang". In black holes the same is true, except these new forces are not strongly felt enough to increase the velocity enough to "escape" gravitational pull.

So in brief, there are no singularities, and photons are certainly not!!

I can't prove it of course!! Much like all the other scientist though...

Answer 2

Singularities in the universe are whatever scientists define them to be and the definition (details) may change as more is learned about them (usually mathematically but also by theory to explain them). There seems to be no pressing need to equate photons with the singularities that help explain black holes. Photons can enter a black hole and become entrapped. Of course one little boy claimed that he pulled up a weed even though the entire world was hanging onto it. So you might say that the black hole was trapped by the photon. What would be the point? A combined singularity?

Answer 3

This is not the usual nomenclatue of physics. Photons are "quantum excitations of the electromagnetic field". They are not really singular in any way---they are certainly "non-localized".
