A new analysis of the distribution of matter in the Universe has revealed a discrepancy in the “lump” dark matter between the late and early universe, indicating a fundamental error in a standard cosmological model. This information was reported in an article from the American Physical Society (APS) titled “Analysis the distribution of matter in the Universe” (APS, 2020).
Cosmologists utilize various modern methods to study the universe. One of these methods is Weak gravitational lenses, which allows for the detection of invisible clusters of dark matter. The Hyper Suprime-Cam Subaru Strategic Program program (HSC-SSP), which has been operating for six years, has been conducting research using weak gravitational lenses. Over this period, the program has scanned 3% of the total celestial sphere and captured light emitted by galaxies up to 10 billion years ago (APS, 2020).
Analysis of 40% of the data collected by the HSC-SSP has shown results that are incompatible with the predictions of cosmological models based on Planck satellite data. This discrepancy has also been observed in weak lensing research, suggesting the existence of a fundamental defect in the standard cosmological model known as the ΛCDM model (APS, 2020).
The HSC-SSP has reported four values for the C8 cosmological parameter, each intended for various analysis protocols. These values are consistent with the results of other studies on weak lensing, but lower than those measured by the Planck collaboration. This difference may indicate a potential error in the ΛCDM model (APS, 2020).
In order to conduct further measurements, cosmologists require improved observation capabilities. In the future, several space telescopes are expected to be launched, including Euclid, the Vera C. Rubin Observatory, the Nancy Grace Roman Space Telescope, and the Chinese Space Telescope. These telescopes will significantly enhance our understanding of the Universe through the observation of billions of galaxies and improved resolution (APS, 2020).
We are on the threshold of an exciting era for cosmology, and the results of the HSC-SSP, as well as their experience in creating reliable analysis methods, will be invaluable for the success of upcoming research (APS, 2020).
