Cómo detectar ondas gravitatorias

The video explains the detection of gravitational waves, originating from the collision of two black holes. It describes the experimental setup involving lasers and mirrors to detect these waves. The process of how gravitational waves affect laser light is detailed, followed by the verification of the detection through replicated experiments, confirming the validity of the findings after a century of anticipation.

What was the significance of having two copies of the experiment located 3000 km apart?

What conclusion was drawn after 100 years of waiting regarding the detection of gravitational waves?
