Dr. Chris Pritchet, an astrophysicist from the University of Victoria, presented: Supernovae and the mystery of dark energy on Dec. 3 at 7:30 p.m. in the Vernon campus lecture theatre. He explored dark energy – a mysterious energy of the Universe that causes its expansion to accelerate. The nature of this dark energy is completely unknown, and represents perhaps the greatest challenge to face physics and astronomy in the past century.
Pritchet and his co-workers have probed the geometry of the Universe, and detected the signature of dark energy with unprecedented precision. In this talk, Pritchet will focus on the telescopes that make this project possible and how observations of distant exploding stars reveal a mysterious new substance that fills space.
