The recent detection of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO) came from two black holes, each about 30 times the mass of our sun, merging into one.
Gravitational waves are usually hunted by measuring distance—how space itself stretches and shrinks ever ...

Here’s what you’ll learn when you read this story: Earth is surrounded by a radio field caused by very low-frequency waves. This field pushes away the Van Allen Belts, a radiation swim-floaty that ...
A team of physicists has developed a method to detect gravity waves with such low frequencies that they could unlock the secrets behind the early phases of mergers between supermassive black holes, ...
Quasiperiodic (QP) very low frequency (VLF) emissions are intermittent bursts of electromagnetic energy, observed in the frequency range of approximately 3–30 kHz, that recur at quasi-regular ...
Earth is surrounded by a radio field caused by very low-frequency waves. This field pushes away the Van Allen Belts, a radiation swim-floaty that surrounds Earth's middle. Van Allen radiation hinders ...
