“The Surprising Expansion History of the Universe”

Adam G. Riess is a distinguished American astrophysicist and cosmologist. He is a Bloomberg Distinguished Professor at Johns Hopkins University and the Space Telescope Science Institute. His groundbreaking research on supernovae as cosmological yardsticks has revolutionized our understanding of the universe's expansion. Dr. Riess will describe his Nobel Prize-winning work to measure and understand the universe's expansion. Then he will discuss the latest developments in the possible nature of Dark Energy and Dark Matter, the behavior of gravity across the universe, their potential impact on the fate of our universe and what open questions are ahead. He also will discuss the life of an astronomer.

His work has led to a number of major discoveries. By measuring the expansion rate of the universe (the Hubble constant) with unprecedented precision, Riess, along with Saul Perlmutter and Brian Schmidt, discovered that the expansion of the universe is accelerating, a finding that completely changed cosmology. His work also revealed that Dark Energy, a repulsive force, is the dominant component of the universe, and he developed innovative methods and tools for using Type Ia supernovae to measure accurate distances to faraway galaxies with unprecedented precision.

Don't miss this opportunity to learn from one of the world's leading cosmologists.

Our next speaker, on April 30, will be Christi Moraga, on “History and Highlights of the Wadsworth Atheneum Museum of Art.” In-person viewing at Christ Church will resume on this date.

The Greenwich Retired Men’s Association offers a free program every Wednesday that is open to the public, both men and women; no reservations are required. Our social break starts at 10:40 am followed promptly by our presentation at 11:00 am. For additional information see https://greenwichrma.org.
