Cosmic Acceleration Persists as New Analysis Reaffirms Dark Energy

An international team finds the universe’s expansion continues to accelerate, refuting a recent claim of slowing growth. By re-calibrating Type Ia supernovae to host galaxy age and mass, the study shows the previous measurements remain robust and dark energy still explains cosmic acceleration; the work counters a South Korean study and reinforces the legacy of Riess, Schmidt and Perlmutter.
