Ripples in the fabric of space, called gravitational waves, are careening across the universe, right through everything and everyone.

Scientists from the Laser Interferometer Gravitational-Wave Observatory (LIGO) experiment have detected some of the waves — a feat Einstein thought impossible 100 years ago — emanating from two colliding black holes.

"The skies will never be the same," physicist Szabi Marka, a LIGO collaborator based at Columbia University, said via a webcam in Washington DC to a crowded lecture hall in New York. "[Gravitational waves] will let us listen to the music of the cosmos."

Tech Insider spoke with Marka, Imre Bartos, also a physicist at Columbia and LIGO, and other researchers about the "revolutionary" new era of astronomy they say has begun.

Here are just a handful of formerly impossible things astronomers can now do with gravitational waves.
