B Finding a black hole

  1. Apr 2, 2017 #1
    If space were like a ocean of ice chunks where everything gradually moves apart and the andromeda galaxy and our galaxy are moving closer to one another. Finding the connection point would find a black hole right. Or is that not possible with the way space moves?

    There is no reason to expect a black hole between our galaxy and the Andromeda Galaxy. The galaxies attract each other due to their combined mass/gravity.

    Black holes are a tiny contribution (<0.1%) to the overall mass in the universe. The Milky Way and Andromeda have a lot of dark matter, some gas, and a smaller contribution from stars.
