    "Astronomy" (from the Greek words astron (ἄστρον), "star", and nomos (νόμος), "law") is the scientific study of celestial objects (such as stars, planets, comets, and galaxies) and phenomena that originate outside the Earth's atmosphere (such as the cosmic background radiation). It is concerned with the evolution, physics, chemistry, meteorology, and motion of celestial objects, as well as the formation and development of the universe.

    There is no such thing as a "dark hole". I think that you are thinking of a "black hole".

    I think you're confusing "black hole" and "dark matter," two quite different things.
