Map of Space-Time Distortions Reveals Universe’s Dark Matter Distribution, Proving Einstein Right

Simons Foundation, April 2023

By closely measuring the distorted path taken by the universe’s oldest light, researchers with the Atacama Cosmology Telescope (ACT) collaboration have mapped out the distribution of dark matter in the cosmos with unparalleled precision. The results shore up Einstein’s theory of gravity, provide new insights into the nature of dark matter and expose critical information about the universe’s fundamental properties.
