Cosmology: The Large and Small of It

Cosmology is the study of the universe on the largest scales – things like galaxies, clusters of galaxies, what the universe is made of, the Big Bang, and the eventual fate of the universe. It is now a well-developed branch of science, with a very accurate model at its core, the so-called ΛCDM (Lambda Cold Dark Matter), but it still contains major mysteries. We don’t know what dark matter and dark energy are, which comprise 95% of the universe. Recent Hubble and James Webb Space Telescope observations show that large scale structures are forming earlier than our theory predicts. Dr. Lynch will discuss the large and the small-scale aspects of cosmology.
