A strange glow in the center of the Milky Way can offer our first glimpse of dark matter.

There is a possibility that the strange gamma-ray glow in the Milky Way forms when dark matter destroys itself. That means that dark matter can send high-energy effects in the matter around it. The glow can form when dark matter particles impact each other. There is a possibility that those dark matter particles annihilate and send some kind of radiation. That radiation can affect. It's the environment directly. Or the dark matter particles, or components, can create a fast-falling false vacuum in their impact point. In that case. 

The fast-falling vacuum forms a situation. Where those quantum fields impact each other. If we think that dark matter can be some kind of false vacuum, and if there can be some kind of wave that comes through that false vacuum, when that wave impacts the opposite wall of that false vacuum. That sends quantum noise through that field. 

Maybe that thing sends energy to particles around that thing, and then those particles start to send gamma-rays. It’s possible that things like gluons are behind those gamma-rays. Gluon is a very small, little-known particle that transmits strong nuclear interaction. When a gluon receives. Some kind of energy load. It releases that extra energy immediately. Or if some kind of energy wave impacts the gluon, or some disturbance in the quantum gravity field affects the gluon and moves it out from its trajectory. That can cause a situation where the gluon sends gamma rays. 

Gamma-rays are the highest-energy and shortest-wavelength form of known radiation. All particles that send or reflect wave movement send those waves with their wavelengths, which are the same as the transmitting particle size. The thing that can cause the hypothetical wobble in the gluon trajectory can also be the gravitational wave. That can form in dark matter interactions. The interaction can be some kind of decay in dark matter. Or it can form in impacts. Or collisions between dark matter particles.
