Hubble Tension: The Evidence of New Physics
The CDM model provides a good fit to most astronomical observations
but harbors large areas of phenomenology and ignorance. With the improvements
in the precision and number of observations, discrepancies between key
cosmological parameters of this model have emerged. Among them, the most
notable tension is the 4 to 6 deviation between the Hubble
constant () estimations measured by the local distance ladder and the
cosmic microwave background (CMB) measurement. In this review, we revisit the
tension based on the latest research and sort out evidence from
solutions to this tension that might imply new physics beyond the CDM
model. The evidence leans more towards modifying the late-time universe.Comment: 39 pages, 6 figures, 3 tables, accepted for publication in Universe

International Congress of Mathematicians: 2022 July 6–14: Proceedings of the ICM 2022
Following the long and illustrious tradition of the International Congress of Mathematicians, these proceedings include contributions based on the invited talks that were presented at the Congress in 2022.
Published with the support of the International Mathematical Union and edited by Dmitry Beliaev and Stanislav Smirnov, these seven volumes present the most important developments in all fields of mathematics and its applications in the past four years. In particular, they include laudations and presentations of the 2022 Fields Medal winners and of the other prestigious prizes awarded at the Congress.
The proceedings of the International Congress of Mathematicians provide an authoritative documentation of contemporary research in all branches of mathematics, and are an indispensable part of every mathematical library
