Question: What will happen if two black holes collide with each other?


  1. Great question! There truth is that no one knows for sure, but we think that they merge into a bigger black hole. At the centre of our galaxy is a black hole that is millions of times heavier than our Sun, which we think might have been the product of the merger of lots of smaller black holes. Albert Einstein predicted through his Theory of Relativity that we should be able to see “gravitational waves” when two black holes merge, which would appear as ripples in the makeup of space. We haven’t been able to detect them yet however.
