Dark Matter: Why It Hides from Us Behind the Atmosphere ⚡ экспресс
Original: "Searching for Ultralight Scalar Dark Matter with Clocks in Low Earth Orbit"
Ultralight dark matter can be screened by Earth's atmosphere, making space-based clocks ideal detectors.

Ultralight dark matter might hide behind Earth's atmosphere like a shield. But in orbit, where ultra-precise clocks operate, that shield disappears. Oscillations of fundamental constants caused by dark matter could turn space clocks into detectors of the invisible. This is a chance to catch what has eluded ground-based experiments.
🎯 If dark matter interacted strongly with the atmosphere, we'd feel it as extra air pressure — but it's vanishingly small compared to normal atmospheric pressure.
