This new map of the Universe suggests dark matter shaped the cosmos

A reconstruction of nearly 9 billion years of cosmic evolution supports the standard model of cosmology, which suggests that mysterious dark matter is the main factor shaping the Universe’s structure. Astronomers traced the X-ray glow of distant galaxy clusters using the most detailed X-ray map of the sky, captured by the eROSITA space telescope. It allowed them to calculate parameters such as ‘lumpiness’ — how much the total mass of matter has concentrated in the cosmic web at any given time due to gravity, especially that of dark matter.
