Group A Galaxies And Black Holes

what is a black hoel?
A black hole is a region of spacetime where gravity prevents anything, including light, from escaping.

what is a galaxy?
A galaxy is a massive, gravitationally bound system that consists of stars and stellar remnants, an interstellar medium of gas and dust, and an important but poorly understood component tentatively dubbed dark matter.[1][2] The word galaxy is derived from the Greek galaxias (γαλαξίας), literally "milky", a reference to the Milky Way galaxy.
