Space Waves


Scientists recently announced a huge discovery—gravitational waves. The waves were detected when a collision of two black holes created ripples or waves, similar to ripples on a pond. These ripples were predicted by Albert Einstein a century ago as a part of his theory of relativity. Scientists have been working to detect these waves for decades and are excited about the information that can be learned from them. In this story you will hear what gravitational waves sound like and learn more about their discovery.
