The dark Side of Energy |
George gave a talk on dark energy, starting with a primer on light, then red shifts and expansion of the universe. Possible reasons for expansion are gravity being repulsive at large scales, quantum vacuum energy, or some new, unknown energy. Vacuum energy was shown to have negative energy.
