The LIGO experiment has confirmed Albert Einstein’s prediction of ripples in spacetime and promises to open a new era of astrophysics
The universe is a noisy place, but we didn’t always have the right ears to hear the sounds—until now.
Various experiments seek different versions of this highly sought-after phenomenon
LIGO scientist David Reitze takes us on a 1.3 billion year journey that begins with the violent merger of two black holes in the distant universe. The event produced gravitational waves, tiny ripples in the fabric of space and time, which LIGO detected as they passed Earth on September 14, 2015.
The LIGO experiment hunts for gravitational waves that are different from those sought by BICEP2. Although both types are elusive, they differ in age and strength—and come from very different places
The discovery of ripples in spacetime will vindicate Einstein—but it can also do so much more
It could mark the birth of a new kind of astronomy
As scientists prepare to catch their first gravitational waves, attention is turning to devices that will let astronomers peek into the invisible interiors of black holes and observe the forbidden, early history of time
Infographic from Scientific American breaks down the technology behind our ongoing search for ripples in spacetime
Physicists say they've heard that the LIGO observatory may have spotted the signature of merging black holes
