Cosmic Wake Exposes Hidden Motions ⚡ экспресс
Original: "First detection of the moving lens effect with ACT and DESI LS"
A subtle distortion in the afterglow of the Big Bang lets us map the full motion of galaxies, including their sideways drift.

Warped starlight, bent by moving galaxies, has been caught for the first time in the oldest light of the cosmos — a speedometer for sideways cosmic motion. This newly glimpsed effect could soon reveal invisible dark matter flows and test gravity on a universal scale.
🎯 The effect shifts the temperature of the oldest light by only a few millionths of a degree — like detecting a candle’s warmth from across a continent.
🎬 Mapping cosmic flows in 3D feels like stepping into the navigator's seat in 'Dune', where space travel depends on reading invisible currents.
