TED-ED: What are gravitational waves? - Amber L. Stuver

The video explains the groundbreaking observation of two black holes colliding, detected by LIGO as gravitational waves. It delves into the nature of gravity, gravitational waves, and how they are ripples in space-time caused by massive objects. The video describes how detectors like LIGO measure these waves and extract information about their sources. It highlights the significance of these discoveries in understanding the universe and mentions other astronomical events that produce gravitational waves. The video concludes with the potential for future revelations as we continue to explore space with new tools.
