Dark matter from 12 billion years ago detected for the first time

Scientists have discovered dark matter around galaxies that existed around 12 billion years ago, the first detection to date of this mysterious substance that dominates the universe.

The findings, obtained through a collaboration led by researchers from Japan’s Nagoya University, suggest that black matter in the early universe is less “lumpy” than predicted by many current cosmological models. If further work confirms this theory, it could change scientists’ understanding of how galaxies evolve and suggest that the fundamental rules governing the cosmos might have been different when the 13.7 billion-year-old star universe was only 1.7 billion years old.
