Join Professor Daniel Sudarsky from Universidad Nacional Autónoma de México for a talk about the cosmological constant on Tuesday, Jan. 11 from 1:30 to 2:45 p.m. via Zoom.
The talk begins with a brief review of the notion of the cosmological constant, followed by a discussion of our
approach to dealing with the interphase between the Gravitational & Quantum realms, how it has developed
and some important lessons we have learned. We will see how these ideas took us to constrain the manner in which
discrete aspects of the space-time structure might become manifest and macroscopic scales.
We will then talk about a modified version of the General Theory of Relativity known as unimodular gravity, which
can under certain conditions smoothly incorporate, in a collective manner, such effects. We will see that at the
cosmic level, the main outcome is a mechanism that can generate a cosmological constant with the correct order of
magnitude, and then, we will briefly talk about current developments whose study is ongoing.
