A wrinkle in space-time confirms Einstein’s gravitation

Gravitational waves are literally distortions in space-time, ripples in the fabric of the universe. Gravity is the weakest of the four fundamental forces, so only the most extreme events — black holes colliding, neutron stars twirling, a supernova erupting — would produce detectable waves. LIGO’s twin detectors, in Louisiana and Washington state, use lasers to watch for these tiny stretches and squeezes of space-time.
