It would emit a lot of radiation. Some distant black holes (or more accurately, the area around the black holes) emit more radiation than an entire galaxy. Such black holes are known as quasars.
Our Milky Way has a supermassive black hole at its nucleus. It is an active radio source. It is probably not a Seyfert galaxy, which is a galaxy of a type characterized by a bright compact core that shows strong infrared emission, though.
The milky way contains about a dozen black holes in the milky way.
The Milky Way appears to have a huge (even for a black hole) gravitational object at the center of it, and this is supposed by a lot of scientists to be a black hole. The arms of our galaxy sweep around the center.
To us, very little.

It seems unlikely that this will occur before our Milky Way galaxy collides with Andromeda. Our solar system seems to be safely in orbit around the supermassive black hole in the center of the Milky Way, but in 4 billion years, when Andromeda (with its OWN supermassive black hole) collides with the Milky Way, it might possibly happen.
The Sun is already in the Milky Way
Mighty Milky Way happened in 2011.

Black holes are common in most galaxies. It is not odd that there would be a black hole in the middle of the Milky Way.
Keeps the whole Milky Way together
Tantei Opera Milky Holmes happened in 2012.
No - The volume of the Milky Way galaxy is larger than the volume of its host black hole. The accumulated mass of the Milky Way galaxy is greater than the mass of its host black hole. The density of the Milky Way galaxy is much smaller than the density of its host black hole.
The milky way was formed by stars gases and dust . The milky way also started as a black hole and stars dust and gases gathered around the black hole.
The middle of the milky way is a black hole and a black hole cannot be made up as matter. The middle of the milky way has no size, but the black hole sucks the light making it look big in pictures. The actual size is nothing.
