How Lasers Helped Researchers Detect Gravitational Waves

For the first time, scientists were able to detect the existence of gravitational waves. These waves, or “ripples in space-time,” were first predicted in Einstein’s theory of general relativity. Over 100 years later, with the help of laser technology, the prediction has proven to be true. The waves were detected by LIGO (Laser Interferometer Gravitational-Wave […]
