Dark Matter Sings in Two Voices
An ultra-sensitive microphone listens not to sound, but to the trembling of space itself. That's how gravitational wave detectors work — LIGO, Virgo, KAGRA.
Listening to the Cosmos Faster: How NUFFT Speeds Up the Hunt for Long Gravitational Signals
An interpreter at a negotiation listens not to individual words but to meaning, and that is why they can keep up with speech. The search for long gravitational signals has so far worked differently: it picked apart every "syllable" of the cosmic ripple, and years of observations cost centuries of computation.
