Ondas gravitatorias y cómo detectarlas

The video explains how moving objects emit waves, using a pool analogy to introduce gravitational waves. It covers the history of gravitational wave theory, predicted by Einstein in 1916, and the indirect evidence found in 1974. The video details the 2015 detection of gravitational waves by LIGO from colliding black holes, highlighting the challenges of detecting faint waves from everyday activities. It concludes with the significance of the experiment that confirmed gravitational waves, marking a century-long scientific achievement.

What evidence was there for gravitational waves before they were directly detected in 2015?
