How Do Gravitational Waves Reveal a Merger?

How does a changing spacetime signal encode masses, spin, and a final remnant?

You followed laser interference into strain, a rising chirp, merger, ringdown, rounded component masses, a remnant, and uncertainty-aware waveform inference.

A restrained artistic reconstruction of two black holes spiralling together while broad gravitational-wave fronts spread through a star field. — Vastward artistic reconstruction. The black holes and wave fronts visualize the merger idea; detectors measure strain on Earth rather than photographing waves in space.
