How scientists finally heard the ripples of violent cosmic collisions
In short: For over a century, gravitational waves remained a theoretical prediction until modern technology allowed us to detect them. This talk explores how LIGO scientists turned Einstein's math into a physical reality.
Astrophysicist Gabriela González explains the journey to confirming gravitational waves—ripples in space-time caused by massive cosmic events. The discovery was made using two extremely precise detectors located in Louisiana and Washington.
The achievement, which earned a Nobel Prize, provides a new way to observe the universe beyond light. It marks a transition from theoretical physics to direct observation of some of the most violent phenomena in existence.
