We are working on understanding the most fundamental problems pertaining to our understanding of the Universe: the origin of the Universe, the evolution of the Universe, the matter contents, and the forces that govern the Universe.
The known matter and radiation, as we know it from the periodic table and electromagnetic radiation, only make up about 5% of the energy density of the universe. The remaining 95% is in the form of Dark Matter and Dark Energy. Currently, we do not have a firm understanding of what Dark Energy and Dark Matter are and of their origin. However, from its gravitational effect on visible matter, we know this dark sector of Dark Energy and Dark matter exists and makes up most of the energy density in the universe. To understand our Universe, we want to understand the dark sector.
As a part of this effort, we are making important contributions to our understanding of dark energy and the Hubble tension, primordial inflation, quantum gravity, the origin of neutrino mass, and dark matter.
