Dr. Adam Riess, Nobel laureate, spoke to the Greenwich Retired Men’s Association about the discovery that the universe's expansion is accelerating, a finding driven by observations of distant supernovae and attributed to mysterious "dark energy." He recounted the initial skepticism and eventual acceptance of this breakthrough, which challenged previous assumptions and required a decade of cross-verification with other cosmological data. Despite confirming the acceleration, the true nature of dark energy and the "Hubble constant tension" remain unresolved, highlighting profound gaps in our understanding of the universe and the need for continued research and funding.
