The first recorded gravitational wave from the merger of two black holes emitted 36 septillion yottawatts — 3.6×10⁴⁹ watts. This is more than all the light emitted by all the stars in the entire observable universe.
When such massive objects collide, we don't just record an event — we see how space and time vibrate with a power that cannot be replicated in any laboratory. This observation has become not only a triumph of science but also a confirmation of Einstein's general theory of relativity.
P.S. In the video, a simulation of what was detected by gravitational wave detectors.
