New Sensors Open Low Frequencies for Gravitational Waves ⚡ экспресс
Original: "Extending Ground-Based Gravitational-Wave Sensitivity to 5 Hz"
By suppressing the Earth's tremors, new sensors unlock low-frequency gravitational waves — a key to mid-sized black holes.

A typical gravitational wave detector is deaf to frequencies below 20 Hz — the Earth's tremor interferes. New sensors are 100 times more precise and pick up oscillations at a frequency of 10 mHz. It's like finally hearing the bass notes of the Universe's symphony — and discovering a whole class of invisible black holes.
🎯 Low-frequency gravitational waves are the only messenger from black holes with masses from hundreds to hundreds of thousands of suns; these "golden means" have hidden from all telescopes.
🎬 Like in 'Interstellar': the instruments sensed how space trembled from distant black holes. Now we hear that tremor with unimaginable clarity.
