Public Lecture by Sean Carroll, California Institute of Technology
Wednesday, December 1, 2010, 7:30 pm - 9:00 pm, Cubberley Auditorium, Stanford
The twentieth century witnessed breathtaking discoveries about the nature of the cosmos. We learned that the universe is over ten billion years old, that it is expanding, and that ordinary objects (stars, planets, human beings) comprise less than five percent of what the universe is made of. The rest is in form of "dark matter" and "dark energy", mysterious substances that physicists are trying to understand. I will discuss the evidence that points us to dark matter and dark energy, as well as some of the theoretical ideas that might help explain them.
