Preuss, email@example.com| The first installment of a new
Science@Berkeley Lab series reporting on the recent Supernova
Workshop sponsored by SNAP, the SuperNova/Acceleration Probe
collaboration, convening leading experts to debate the best ways
to study dark energy with exploding stars. Starting in the late
1980s the Supernova Cosmology Project (SCP), based at Berkeley
Lab and led by Saul Perlmutter, pioneered methods of finding
enough exceedingly bright, remarkably uniform, very far-off Type
Ia supernovae to measure the expansion of our universe. The idea
was to compare the brightness of these objects, which is a
measure of their distance, with their redshifts, a measure of
how much the universe has expanded since they exploded. At a
uniform rate of expansion, redshift and brightness would have a
consistent relationship. A supernova brighter than the
relationship dictated would also
