Just a fantastic photograph of those Fermi Bubbles in our favorite galaxy.
I was looking at it wondering what seemed to be missing.
Just to get that picture they had to tweak it and exclude everything except the highest energy gamma rays.
The tricky part is that camera is still inside this galaxy but the "scattered background radiation" has a pattern.
Then it makes sense, and there's the missing part.
Its like the surface of an elliptical galaxy that connects the center to the edges.
We can't normally see any of this, including the black hole, but if we know its there and it has these plumes/bursts/bubbles (as shown in the picture from NASA/ESA) then there's still something not visible with only tiny clues as to its existence because its energy level is much lower than the hot core. All I did was to generally indicate where it would be. If this is reasonably true than that would make our very own favorite galaxy a space engine! Just the black hole in the center of the galaxy could be seen as a space engine, but the included circulation is completing an integrated system of energy-exchange. Also it would explain why there isn't any dark matter, because the propulsion is invisible. The reason they're looking for the dark matter is because of this motion that can't be explained by Newtonian mechanics. The motion is induced by the energy of the center (which comes from the inward-falling disk to the center) where it is converted back out to the edges as a form of propulsion.
