For all we understand about the universe, 96% of what’s out there still has scientists in the dark. Astronomical observations have established that familiar matter—atoms—accounts for only 4% of the weight of the cosmos. The rest—dark matter and dark energy—is invisible to our telescopes. But what really is this dark stuff? How do we know it’s there? And what does it do? From the formation of galaxies to the farthest reaches of space, it appears that darkness rules. Without dark matter and dark energy, the universe today and in the far future would be a completely different place. Join us in a discussion with leading researchers who smash together particles, dive into underground mines, and explore the edges of the known universe in search of clues to nature’s dark side.

Can the entire universe be explained with a single, unifying theory? This is perhaps the most fundamental question in all of science, and it may also be the most controversial.
The 2011 Isaac Asimov Memorial debate, moderated by Hayden Planetarium Director Neil deGrasse Tyson, featured a compelling discussion with six of the world’s leading voices on the subject: Dr. Katherine Freese, professor of physics at the University of Michigan; Dr. Jim Gates, professor of physics at the University of Maryland-College Park; Dr. Janna Levin, professor of physics and astronomy at Barnard College; Dr. Marcello Gleiser, professor of physics and astronomy at Dartmouth College; Dr. Brian Greene, professor of physics and mathematics at Columbia University; and Dr. Lee Smolin, theoretical physicist at Perimeter Institute for Theoretical Physics.
2011 Isaac Asimov Memorial Debate - "The Theory of Everything"
What do we really know about the universe? What mysteries are today's top cosmologists investigating? Join a discussion with leading cosmologists to hear fresh perspectives on some of the deepest questions in modern science: What is the mysterious dark matter that fills intergalactic space? Was there another universe before the big bang, and what will happen to ours in the distant future?
Canada’s Perimeter Institute for Theoretical Physics celebrates its 10th Anniversary with Quantum to Cosmos: Ideas for the Future. This innovative festival, October 15th, to 25th, 2009, takes a global audience from the strange world of subatomic particles to the outer frontiers of the universe. In the introductory panel discussion that can be viewed by clicking on the link just above, or by clicking on the picture just below, 9 physicists discuss what lies ahead in physics --- from the Quantum to the Cosmos.
