So here’s the deal. Three astronomers, Saul Perlmutter, Brian P. Schmidt, and Adam G. Riess won the Nobel Prize for physics this week. Why is this interesting? Becuase of what they discovered. With the help of a type 1a supernova (a type of exploding star) theydiscovered that the expansion of the universe is actually speeding up, due to an antigravitatonal force called “dark energy.” Although they don’t know exactly what dark energy is, they do know that it’s pushing galaxies apart. An article in the New York Times states that “If the universe continues accelerating, astronomers say, rather than coasting gently into the night, distant galaxies will eventually be moving apart so quickly that they cannot communicate with one another and all the energy will be sucked out of the universe.” Poor Einstein, they believe that there are a bunch of different universes with different properties (obviously we live in one that is habitable). Pretty cool, eh?
