The trembling of space sounds like an orchestra. Gravitational waves caught by the LIGO and Virgo detectors tell of black hole collisions. Sometimes the music carries off-key notes — tiny deviations from Einstein's score. They might whisper of new physics or simply of dust on the bows.

In the new study, scientists looked for a specific glitch — one that depends on the mass of the colliding objects. As if the orchestra had an invisible threshold: light instruments play in tune, while heavy ones start to falter. This threshold could appear if gravity behaves differently at large masses, or if black holes are not quite black holes but exotic objects like wormholes (tunnels in spacetime).

The SCoRe method used in the work acts like a smart conductor: it compares noise across different detectors and accumulates statistics over many events. If the off-key pattern were common to all instruments and repeated from concert to concert, it would be noticed. But the result was negative. The Bayes factor, a measure of confidence, ranged from 0.16 to 0.5 depending on the assumed boundary. This means the data speak against such a boundary rather than for it. An additional check for excess noise correlation gave a factor of 0.07—exactly what you'd expect from random noise.

So nature reminded us of its love for simplicity. The black hole orchestra still plays Einstein's notes without hidden pauses. But this is not the end: quieter signals and new detectors may still bring surprises. For now, we hear only the pure symphony of gravity.
