Dark Energy and the Accelerating Universe: New Physics or The New Aether

Michael Turner, Head of NSF Mathematical and Physical Sciences Directorate
WIGNER Auditorium

Five years ago it was discovered that the expansion of the Universe is speeding up and not slowing down. The evidence for cosmic speed up has grown stronger since, and the data indicate that 2/3 of the Universe is in the form of a mysterious dark energy whose repulsive gravity is driving this cosmic speed up. The nature of the dark energy is one of the most profound mysteries in all of science. Cosmological measurements made over the next decade should shed some light on this mysterious, aether like stuff and provide new insights on the nature of matter, space and time as well as the destiny of the Universe.
