Researchers analyze hydrogen's absorption of light to map dark matter distribution in the cosmos, possibly indicating a new particle, published in the Journal of Cosmology and Astrophysics.
Hydrogen atoms, abundant in the universe, act as a 'dye' to trace dark matter's gravitational pull, creating a 'Lyman-Alpha Forest' of absorption lines in light spectra.
Each atom leaves a unique signature as it absorbs light, with hydrogen being the most prevalent element. The analogy is drawn between hydrogen acting like a 'dye' following the 'water' of dark matter's gravitational pull.
