How Particle Clouds Bend Light Rays ⚡ экспресс
Original: "Hadronic lensing"
A new approach accounts for clouds of invisible particles — and changes the calculation of light bending around black holes.

Surprising fact: light rays bend not just from gravity, but also when slicing through clouds of invisible particles called hadrons. New research has precisely modeled this effect, which may one day hand astronomers crisper images of black holes.
🎯 As it turns out, at ultralow density — a mere handful of particles per cubic meter — the beam's bend shifts by a measurable amount.
🎬 Light decelerating in a particle cloud echoes the 'slow glass' from sci-fi: light oozes through over years, letting you glimpse the past.
