Online Seminar〝Seven hints that early-time new physics alone is not sufficient to solve the Hubble tension〞


Star-UBB Seminar Series:- Seven hints that early-time new physics alone is not sufficient to solve the Hubble tension

It appears by now established that solving the Hubble tension requires new physics operating at early times, i.e. prior to recombination. But is that really the end of the story? Based on Miller’s law (which states that the number of objects the average person can hold in working memory is about seven), the speaker will present seven independent hints pointing towards the fact that the Hubble tension requires more than just early-time new physics, and will discuss his personal thoughts about what the most promising scenarios might be moving forward (also keeping in mind the potential tension in S8).

Scientific and Technological Advanced Research- Babeș-Bolyai University(Star-UBB) Seminar Series in Gravitation, Cosmology and Astrophysics

Presently a period of rapid and intense change are being witnessed in our understanding of the gravitational force, at a rate that is quickly increasing since the important observational discoveries of the late 1990s. With the advent of new observational techniques, the emergence of important cosmological and astrophysical paradigms can be seen that lead to a deep change in our understanding of the Universe. Astronomical observations strongly suggest that at large scales the force of gravity may not behave according to standard general relativity, and that a generalization of the gravitational action, either at the geometric level, or at the matter level, may be required for a full understanding of the gravitational interaction.

The goal of the present seminar is to bring Theoretical Gravitational Physics closer to the observations and experiments, and to discuss current topics in general relativity, high-energy physics, astrophysics and cosmology.
