The Top 10 Unanswered Questions in the Universe

In conjunction with the Perimeter Institute for Theoretical Physics in Waterloo, we assembled a panel of 10 prominent physicists from around the world, and asked each of them what they think is the biggest question that science has, so far, been unable to answer. They gathered at Glenn Gould Studio at the CBC Broadcasting Centre in Toronto, before a live audience, and made their arguments. Then the audience had a few suggestions of their own.

  • Dr. Sean Carroll, a Senior Research Associate in Physics at the California Institute of Technology. How did the Universe Begin?

  • Dr. Katie Freese, a professor of physics at the University of Michigan. What is the Universe made of?

  • Dr. Andrew White, a professor of physics at the University of Queensland in Australia. Does biology operate on the quantum level?

  • Dr. Gordon Southam, a professor of biology and earth sciences at the University of Western Ontario, and Canada Research Chair in Geo-microbiology. Is there life elsewhere in the Universe?

  • Dr. Julian Barbour, an independent British physicist and popular science writer. Does Time Exist?

  • Dr. Bill Wootters, a professor of physics at Williams College in Massachusetts. Is there a physical theory, yet to be discovered, that underlies quantum theory and explains its structure?

  • Dr. Sabine Stanley, an assistant professor of physics at the University of Toronto. Will we ever be able to travel to the stars in a single generation?

  • Dr. Anton Zeilinger, a professor of physics at the University of Vienna. How real is reality?

  • Paul Delaney, a Senior Lecturer in physics and astronomy at York University in Toronto. Are there Earth-like planets elsewhere in the Universe?

  • Dr. Michael Luke, a professor of physics at the University of Toronto. What is empty space made of?
