LIGO

Researchers have identified a direct relative of the first source to emit gravitational waves and light simultaneously.

If proven correct, the theory could revolutionize our understanding of the cosmos.

Last year's collision was the first in which scientists could actually see what was happening during and after the collision.

The same heavy elements that boost our economy could boost theirs.

It's not just about the detectors picking up a signal—scientists also have to realize it's there soon enough to enlist colleagues in the investigation.

"Now that we're in the business of finding things, we can say, well, soon we'll know."

The video rewrites our understanding of the event.

One of the stars that collided had to have been at least 6.6 miles across—absolutely tiny compared to our sun.

They'e even predicting where the event is most likely to occur.

It's a truly ground-breaking discovery.

Scientists from across the globe will reveal their findings during a press conference starting at 10am ET.

Rainer Weiss, Barry C. Barish and Kip S. Thorne win for "decisive contributions to the LIGO detector and the observation of gravitational waves."

Network of detectors in U.S. and Europe was used to zoom in on the source of gravitational waves.

The ripples in space-time were first predicted by Einstein more than 100 years ago.

Discovering extra dimensions would help solve many of the universe's biggest mysteries, like why the universe is expanding at an accelerating rate.

LIGO's detection is a milestone for gravitational wave astronomy.

Scientists expect to see many more black holes, as well as supernovas, neutron stars and possibly dark matter in coming years.

Gravitational wave researcher, Peter Graham, explains how LIGO validated the signal they detected.

"This [was] truly a scientific moon shot, and we landed on the moon."
