The Nobel Prize for physics has been announced and, like the one for Medicine yesterday, it’s a three-way split:

The Royal Swedish Academy of Sciences said American Saul Perlmutter would share the 10 million kronor ($1.5 million) award with U.S.-Australian Brian Schmidt and U.S. scientist Adam Riess “for the discovery of the accelerating expansion of the universe through observations of distant supernovae.”

In other words, Dark Energy. The most revolutionary discovery in cosmology since the Big Bang.
