The Dark Side of the Universe

The Universe appears to be dominated by an unknown form of matter, known as "dark matter", responsible for pulling matter together and for holding together galaxies such as our own Milky Way, and by an even more mysterious form of energy, known as "dark energy", which governs the fate and expansion of the universe.  Dr. Profumo will discuss how we got convinced that the Universe is indeed "dark" and how we think we can discover what dark matter and energy are.
