And it seems incredible to think there is not a cluster of black holes at the center of EVERY galaxy.
Likewise, it seems reasonable to believe there is a vast amount of non-glowing material extending out from the galaxy's glowing spiral arms.
Like any good drain, gravity sucks matter into the galaxy, first at its periphery, where we don't see it. Finally it is a dense enough collection to start igniting as stars and emit light we can see, then getting denser to the center where at the very center it is extremely likely to have black holes form, including super incredibly massive ones.
And it seems reasonable that once you get super incredibly massive enough, you can actually blast apart, or squeeze out a huge burst of energy (enough that your remaining effective mass is no longer quite so incredibly super massive)
That last bit is a particular stretch if you want to believe a black hole is a one-way trip for matter.
But if such outbursts ARE common, it does seem like either they need to be polar-aligned with the galaxy (implying the center black hole mass shares the spin axis of the galaxy) or the energy would probably blow a noticable pattern into the galaxy's arms.
But hey, maybe that is where some other galaxy shapes might come from. Or.. imagine such a burst in the plane of the galaxy which blew out an empty space in the galaxy's current 'rings'
The original mass is still rotating as before but now you are starting with 'straight out' arms, when then slowly wind up as the spiral arms we know and love. And thus from working out how long ago a galaxy's spirals might have been straight out, you work out how long since the last core dump.
And I changed my mind, the core dump does not blow out a gap in the disk, it actually BECOMEs the material of the exacly two arms which start the next cycle of that particular galaxy.
Yeah, now THAT's a theory! Nucleus gets really dense... explodes in two directions.. makes two long, straight arms (and probably a sphere as well). Starts collapsing again and the arms wind around until you have a spiral galaxy.

A supermassive black hole in the cores of these galaxies is accreting matter. As the matter is drawn into the black hole, the angular momentum of the matter is conserved by it swirling around the black hole, like spinning water going down a drain. As the matter gets drawn in closer and closer to the event horizon of the black hole, the accreting matter is accelerated, round and round, to close to the speed of light. That releases a huge amount of energy in the form of gamma ray bursts, gravitational waves, lots of neutrinos, and other even more exotic forms of radiation. The short answer is the black hole at the center of these types of galaxies produces the energy.

well, if u would know einsteins equation, energy can be converted to mass and mass to energy. even a lil bit of mass, if lost, can give rise to immense amounts of energy. In stars and quasars and other such galactic things, some of the mass is converted to a huge amount of energy in the form of fusion reactions.

Simple, the universe is a fluctuating living thingunto itself, it powers the suns the black holes and its all under a very strict equilibrium.
Dont believe the bullshit science explanations, because theyre untrue.
