Black Holes and Colliding Galaxies
Question: If galaxies have black holes and two nearby galaxies were colliding, would these galaxies give birth to one great black hole? If it’s true that everything is expanding from everything else how can this be true?We can understand this in terms of an uneven distribution of matter in our universe. If you take an ordinary rubber balloon and using black magic marker pen to place black dots on the surface of that balloon, when we inflate the balloon, every dot will move apart from all of the other dots. The gravitational pull of a black hole is so overwhelming that not even light can escape. Now, this means that astronomers cannot look at a black hole. But now strong telescopes are able to establish the evidence of them. We also know that after a large star crumbles in upon itself and forms a supernova that a small black hole can form in its center. Supernovae give us with so much information about colliding galaxies and their respective black holes that there is an entire segment of astronomy dedicated to the discovery and study of supernovae. That’s why the astronomers at Windowpane Observatory have established the name a star program, which allows those interested in astronomy and science to creatively contribute to exploration into supernovae and the search for earth-crossing asteroids.
