Dark energy surprise suggested by super set of supernovae

EarthSky’s Dave Adalian talks with astrophysicist David Rubin about new evidence that dark energy might evolve over time. Type Ia supernovae let us precisely measure cosmic distances, and gave us the first evidence of the universe’s accelerating expansion. New analysis of over 2,000 Type Ia supernovae has found evidence that dark energy might evolve over time. If so, it would point to surprising new physics that could affect the fate of the uni…
