JWST Just Mapped 800,000 Galaxies and Revealed Dark Matter

The release of the 2026 dark matter map marks a definitive shift in how we approach the cosmos. For decades, we were in the hunting phase, trying to prove that dark matter existed and attempting to catch a single particle in a laboratory. While we still haven't touched a dark matter particle, we have moved into the surveying phase. We are no longer asking if it is there; we are busy measuring its dimensions, its density, and its influence on the growth of everything we can see. This map of the Sextans field is essentially the first page in a new atlas of the invisible universe. ▀▀▀▀▀▀ Timestamps: 0:00 Dark Matter 1:05 The Cosmic Lens 4:20 The COSMOS-Web Survey 7:15 Mapping the Filaments 10:22 Beyond the Standard Model 13:15 The Architect of Life ▀▀▀▀▀▀ Fexl Spanish:    / @fexl_es   Fexl Portuguese:    / @fexlpt   Fexl Ukraine:    / @fexl_ua   ▀▀▀▀▀▀ References: Nature Astronomy (January 2026): An ultra-high-resolution map of (dark) matter: https://www.nature.com/articles/s4155...
