How a Crystal’s Hidden Order Sharpens Gamma-Ray Telescopes ⚡ экспресс
Original: "Satellite-borne $$γ$$-ray astrophysics from coherent interactions in oriented crystals"
A slight crystal tilt—within a hair’s width—transforms it into a super-efficient gamma-ray detector, enabling lighter space telescopes.

High-energy gamma rays from space vanish in a flash, but a trick with crystal alignment turns that flash into a fountain of particles, making them easier to catch. This new telescope design could sniff out dark matter.
🎯 A gamma ray of sufficient energy can spontaneously become an electron and its antimatter twin, a positron, as [scientist:Paul Dirac]Paul Dirac[/scientist] predicted—a vivid proof of E=mc².
🎬 The spontaneous creation of matter and antimatter from pure energy, central to this detector, is a staple of science fiction, from Star Trek’s warp drives to the weaponry of Angels and Demons.
