RMA Discussion: What’s Out There & Where’s It Going: The 20th Century Revolution in Cosmology
Throughout most of human history, the heavens were viewed as eternal, infinite, and unchanging. This view was completely upended over the course of the last one hundred years starting with Einstein’s theory of gravity, through Hubble’s discovery of the expanding universe, and culminating in the discovery of the accelerating expansion at the very end of the century. We now know that our universe had a beginning; what we do not know is how or if it will end. Central to our current understanding of the universe is a mysterious phenomenon called “dark energy,” the nature of which is poorly understood, but which governs the future. 

Steve Holmes will describe this story as it played out over the 20th century and highlight some of the outstanding questions for which we seek answers in the 21st.  

Dr. Holmes holds a Ph.D. in experimental particle physics from Harvard University. He spent five years on the faculty of Columbia University, followed by thirty-five years on the scientific staff at the Fermi National Accelerator Laboratory. His area of expertise is the design, development, construction, and operation of high-energy particle accelerators. He has a long-term interest in astronomy and astrophotography. Dr. Holmes is a Fellow of the American Physical Society.

Co-sponsored by the Retired Men's Association of Greenwich. Registration required.
