When we say “powered by black holes” we mean that the immense gravity of the black holes superheat the in falling material, which creates the tremendous radiation of light. The light comes from near the black hole. It does not escape from inside the black hole.

Yes, we’ve considered EM energy as a source of dark matter. It doesn’t work for numerous reasons I’ve discussed in several posts.

DanB You don’t have to go into deep space to find out how neutrinos interact with other matter. The Large Hadron Collider at Cern has found several different kinds of neutrinos. The guys there say they come in flavors.
“Neutrinos come in three flavors: electron, muon, and tau, each named for the charged particle with which it is associated. But the flavors are not pure essences—each is made up of a different combination (or superposition) of three ingredients, or mass states.”

Your quote: “Quasars are distant objects powered by the supermassive black holes in the centers of galaxies. They give off tremendous amounts of light and energy, and so we can see them across billions of light years.”

In the SM nothing escapes from Black Holes not even light. Yet you say, “Quasars give off tremendous amounts of light and energy”. Which is it?
If Quasars are “powered by” BHs then energy must escape from BHs which is a contradiction.

Also, concerning Dark Matter. Have you ever considered the possibility that DM consists of electromagnetic energy? EME can be dark and have mass since it interacts with other matter in the galaxy it inhabits. I assume DM only attracts matter but its’ “cousin” Dark Energy expands the space between the galaxies.

Do neutrinos take different forms in the dark reaches of space. Do they clump together. With so many neutrinos ejected into space there has to be a mechanism in which they found back into matter.

I look forward to your posts every week Brian, Thanks!
Regarding the nature of dark matter particles;
Since they seem only to be affected by gravity, and perhaps a small probability of interacting with other DM particles;
should we think of them simply oscillating through the galactic gravitational potential?
Just like a simple harmonic oscillator, each DM particle cycles from one side of the galaxy to the other.
All of them on random trajectories.
So we might expect the size of the DM halo around a mass concentration to be related to that mass?
Could this also be said to be the “temperature” of the DM?
Perhaps study of this relationship could reveal the interaction cross-section?
