There is only theory available no hard evidence. I think that there is no black whole at the center of galaxies, I believe that the gravitational pull off all the stars at the center are pulling as well as pushing away. So stars are actually either being aborbed into bigger stars >> that's why its brighter toward the center >> or the more stars that are being pulled in toward the center of the galaxy are dancing around each other making the center of the galaxy spin faster >> from our perspective we cannot tell what's really going on at the center of the galaxy.
What do you think is really happening?

Most people *don't* believe galaxies are black holes. A black hole is a region of space from which nothing can escape, even light.
Since you can't see a black hole (that light that isn't escaping), one has to rely on indirect evidence.
If you've found a large mass concentrated in a small volume, and if the mass is dark, then it's a good guess that there's a black hole there.
It'll be quite some time before we can get "hard evidence" of a black hole. We don't even have "hard evidence" that those are stars; it's just indirect evidence.

Well people generally assume that galaxies are black holes spinnig into a vortex pf nothing because of all the sci-fie movies giving us wrong ideas about the the space beyong Earth.I agree with u on the point that there can be a gravitional pull at the centre of the universe and that is the force pulling all the stars closer to it and making it appear brighter.

Scientists didnt assume this a few years back but it has recently been discovered that there is a black hole at the center of the milky way galaxy. This discovery along with other photos of galaxies by the hubble telescope has just recently led scientists to believe most all galaxies were formed around black holes.

Electromagnetics. The current is flowing through the center of a galaxy, perpendicular to it. The galaxy is the charged body rotating in the spinning magnetic field.

Black holes were observed in the universe almost ten years ago...

A black "whole" is greater than the sum of its black parts.
