SMP 4/13/04 | Dark Energy and Our Runaway Universe | Speaker: Gregory Tarle

Speaker: Professor Gregory Tarlé (U-M Physics)

Edwin Hubble discovered in the 1930’s that our universe is dynamic, expanding away from a birth about 14 billion years ago. Ever since, scientists have wondered about its destiny. Would the expansion slow to a halt and then collapse or would the expansion continue forever, slowed weakly by the gravity of the matter within? Now it appears that a mysterious dark energy has taken over the universe and is accelerating its expansion, driving distant galaxies out of our observable universe. Professor Tarlé will explore the experimental evidence for the existence of this dark energy and examine some of the possible explanations of its nature.
