The cosmos, once understood as a stagnant place, composed of the ordinary, is now an expanding universe filled with dark mysteries. The formation and growth of black holes, dark matter halos, the accelerating expansion of the universe, the echo of the big bang, the discovery of exoplanets, and the possibility of other universes - these are some of the puzzling cosmological topics of the early twenty-first century. Dr. Natarajan will delve into the ideas that reshaped our universe over the past century and provide a tour of the “greatest hits” of cosmological discoveries. The acceptance of such new ideas about the universe and our place in it has never been linear and always contested even within the scientific community. However, as shifting and incomplete as science always must be, it offers the best path we have toward making sense of our wondrous, mysterious universe.
