Abstract:

Observations of very distant exploding stars (supernovae) show that the expansion of the Universe is now speeding up, rather than slowing down due to gravity as expected. Other, completely independent data strongly support this amazing conclusion. Over the largest distances, our Universe seems to be dominated by a repulsive "dark energy" --- an idea Einstein had suggested in 1917, but renounced in 1929, anecdotally as his "biggest blunder." Dark energy stretches the very fabric of space itself faster and faster with time. But the physical origin of dark energy is unknown, and is often considered to be the most important unsolved problem in physics; it probably provides clues to a unified quantum theory of gravity.


Short Bio:

Alex Filippenko received his Ph.D. in Astronomy from Caltech in 1984 and joined the UC Berkeley faculty in 1986. One of the world's most highly cited astronomers, he has coauthored about 570 scientific publications and is the recipient of numerous prizes for his research. He has won the top teaching awards at Berkeley, and students have voted him the "Best Professor" on campus six times. In 2006, he was named the Carnegie/CASE National Professor of the Year among doctoral institutions. He has produced a 96-lecture astronomy video course with The Teaching Company and has coauthored an award-winning astronomy textbook.
