Mapping the Universe - Dark Energy, Black Holes, and Gravity – With Chris Clarkson

This talk explores how cosmological surveys map galaxies and what those observations reveal about the universe’s structure and expansion. It also discusses evidence for dark matter and dark energy, Einstein’s theory of gravity, black holes, and gravitational waves.
