      If you have two black holes coming together, they start to orbit each other first, spinning around each other getting closer and closer together. Eventually when they crash together they combine and create an even larger black hole. We call this type of event a black hole merger. When they merge, they send ripples through space called gravitational waves.

      Similar to what Jade said, they orbit eachother until they come together to form a bigger black hole and when this happens, we can measure gravitational waves on Earth with instruments like LIGO 🙂
