History

Historical Context

In 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO) made history by detecting gravitational waves, confirming Einstein's 1916 prediction. This achievement stemmed from decades of research, including early concepts by Gerstenstein and Pustovoit in 1963. Recent advancements at institutions like the University of California, Riverside, aim to enhance gravitational-wave detection, potentially revolutionizing our understanding of the universe.
