Every black hole has its own 'voice'—the frequency at which it vibrates. But if dark energy lurks nearby, its sound changes. New calculations show exactly how, and hint that we might hear this in gravitational waves.
🎯 The 'grayness factor' owes its name to neutron stars: it was devised for calculations of their radiation, and it gained widespread fame thanks to the works of [scientist:Stephen Hawking]Stephen Hawking[/scientist] on black hole evaporation.
