GW250114: Clearest gravitational-wave signal enables tightest test yet of general relativity

On 14 January 2025 the GW250114 black‑hole merger produced the clearest gravitational‑wave signal ever recorded, allowing measurement of multiple post‑merger “tones” and the most stringent test to date of Einstein’s general relativity. The waveform upheld GR, while researchers note future detections could probe quantum‑gravity effects.
