Gravitational Waves
Gravitational waves were first theorized by Albert Einstein in 1916. Since then, scientists have been working to detect them. On February 11th, 2016, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected the first gravitational waves. This historic discovery has created a new field of astronomy, allowing us to explore the universe in a new way. Gravitational waves are ripples in space-time created by massive cosmic events like the merging of two black holes or a supernova. As these events occur, they send out a wave of energy that can be detected by instruments like LIGO.
