The Discovery
In September 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected gravitational waves for the first time. This historic discovery confirmed a prediction made by Albert Einstein’s theory of general relativity a century ago. The LIGO observatory detected a signal from two black holes that merged over a billion years ago. The collision caused a ripple in spacetime, which traveled through the universe at the speed of light and was detected by LIGO. This detection opened up a new window to observe the universe andstudy the mysteries of gravity.
What Are Gravitational Waves?
Gravitational waves are ripples in the fabric of spacetime that propagate through the universe at the speed of light. They are produced when massive objects, such as two black holes or two neutron stars, orbit each other and accelerate. This acceleration generates ripples in spacetime, which propagate outwards. These waves are extremely weak and difficult to detect, as they cause tiny distortions in spacetime, much smaller than the width of a proton.

The Technology Behind the Discovery
The detection of gravitational waves required highly sophisticated technology. The LIGO observatory consists of two identical detectors, one in Louisiana and one in Washington state. Each detector consists of two 4-kilometer-long arms, arranged in an L-shape, with laser light bouncing back and forth between mirrors at the ends. When a gravitational wave passes through the observatory, it causes the arms to stretch and compress by a tiny amount, changing the distance between the mirrors. This change is detected by the laser, and the signal is sent to a computer for analysis.
