The Sound of Black Holes Colliding
Thanks to light signal detections, we can now hear what it sounds like when black holes collide. After a significant amount of frequency shifting, these light signals were able to be translated into audible sound waves.
This is significant in the science community, as it proves that gravitational waves exist; a prediction Einstein proposed nearly 100 years ago. After this, there is much to be said for the future of sound detection in distant regions. Read more here.
