Summary: Feature Guest: Ludovic Van Waerbeke Large scale surveys of the universe are quickly becoming key to making new discoveries at the cutting edge of astronomy. Case in point is the Cosmic Evolution Survey (or COSMOS), which incorporates data from 446,000 galaxies. Today we're joined at The Star Spot by Ludovic Van Waerbeke whose survey-based research has helped us expand our understanding of the expanding - and accelerating - universe, confirming the existence of an unknown source of energy, or dark energy, and providing a map of the large scale dark matter distribution of the cosmos. About Our Guest Ludovic Van Waerbeke is Professor of Physics and Astronomy at the University of British Columbia and Senior Fellow of the Canadian Institute for Advanced Research in the Cosmology and Gravity program.
