Expanding Universe theory gets Nobel Prize
Three U.S.-born scientists won the Nobel Prize in physics Tuesday for discovering that the universe is expanding at an accelerating pace, a stunning revelation that suggests the cosmos will eventually freeze to ice.
Saul Perlmutter and Adam Riess of the United States and US-Australian Brian Schmidt won the 2011 Nobel Physics Prize Tuesday for their research on supernovae, the Nobel jury said.

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. Working in two separate research teams during the 1990s - Perlmutter in one and Schmidt and Riess in the other - the scientists raced to map the universe's expansion by analyzing a particular type of supernovas, or exploding stars.
They found that the light emitted by more than 50 distant supernovas was weaker than expected, a sign that the universe was expanding at an accelerating rate, the academy said.
