A binary black hole signal has been detected, allowing for the first probe of the event horizon region. This detection has provided new insights, with some reports suggesting the identification of "fingerprints" or a "signature" of the event horizon, while others mention the observation of "frame dragging" around merging black holes. The signal is described as the loudest gravitational-wave signal yet, offering a direct window into the event horizon, a region where light and sound are trapped.
