Second Black Hole at the Center of the Milky Way

Tsalg pastes "A second black hole lurks at the centre of our Galaxy, according to astronomers who have watched a cluster of stars spinning around it. Just three years ago, astronomers confirmed that the Milky Way revolves around a supermassive black hole, called Sagittarius A*, which is about 2.6 million times more massive than the Sun. But now a much smaller black hole, just 1,300 times our Sun's mass, has been found orbiting about three light years away from its supermassive cousin. placing it intermediate between the relatively small (stellar mass) black holes in the Milky way Galaxy and the supermassive black holes found in the nuclei of galaxies."

That would be a movie effect, not reality. The spiral arms of the galaxy are a density wave propagating through the stars and dust of the galaxy's disk. Think of how sound can be described as a density wave propagating through the air. Same thing.

And some very interesting gravity waves will be generated!
