Here’s something non-COVID that reminds us that the universe is a big and wonderful place. Astronomers studying the collision of two black holes 2.4 billion light years away have uncovered evidence of Elvis.
The binary system, known as GW190412, featured two black holes of vastly unequal masses circling each other. They spiraled closer and closer to each other until they merged in spectacular fashion.
When this merged occurred, the masses created two different frequencies. Scientists then converted those frequencies into notes we can hear and found a “C” that moved up to a “G” on a piano. The resulting two tones sound remarkably like the first two notes of this Elvis song (The “Wise man say” part).
