Our universe is rippling with waves caused by massive events, such as merging black holes. Up until yesterday, we didn’t have any evidence of long-wavelength, ‘background’ #GravitationalWaves. But now @nanograv has announced a detection! A network of pulsars measured very carefully has revealed a faint hum in spacetime itself. Though luckily you don’t need pulsars to detect these cookies, a mouth works just fine 😉
