How Dark Matter Influences the Rhythm of Cosmic Collisions ⚡ экспресс
Original: "Probing the Nature of Dark Matter Self-Interactions Through Observations of Massive Black Hole Mergers"
The future LISA detector will distinguish dark matter models by the merger rate of distant black holes.

Invisible dark matter may slow the mergers of galactic cores. If its particles jostle slightly, then the supermassive black holes at the centers of galaxies merge more slowly. The future LISA detector will hear these cosmic collisions and, by their rhythm, determine which model is correct. The key to the puzzle is 70 'loud' mergers.
🎯 Fritz Zwicky suspected dark matter's existence in 1933, and Vera Rubin proved it in the 1970s: galaxies rotate as if held by an invisible framework. Today it's clear—there's five times more dark matter than ordinary matter.
