"The universe is not silent. It hums with a rhythm that has been playing since before Earth was born—and we are part of it."
In 2023, scientists confirmed the existence of a low-frequency hum of gravitational waves, a slow cosmic pulse that squeezes and stretches everything it touches, including you and me [citation:1]. This hum likely emanates from supermassive black holes merging at the centers of galaxies, or possibly from the very birth of the universe itself [citation:1]. As astrophysicist Adam Frank wrote: "every proton and neutron in every atom from the tip of your toes to the top of your head is shifting, shuttling, and vibrating in a collective purr within which the entire history of the universe is implicated" [citation:1]. You are not separate from the cosmos—you are humming in tune with it.
