Using the Hyper Suprime-Cam (HSC), a team led by Princeton University has studied the distribution of dark matter and found a discrepancy between the 'clumpiness' (S8 value) of dark matter in the present universe versus the early universe. This discrepancy could point to an unrecognized error or hin
The Big Bang Theory explains how the universe began with an infinitely hot and dense single point that inflated to form the ever-expanding cosmos we see today.

Japanese astronomers have developed a new artificial intelligence (AI) technique to remove noise in astronomical data due to random variations in galaxy shapes. After extensive training and testing on large mock data created by supercomputer simulations, they then applied this new tool to actual data from Japan’s Subaru Telescope and found that the mass distribution derived from using this method is consistent with the currently accepted models of the Universe. This is a powerful new tool for analyzing big data from current and planned astronomy surveys.
