Is time travel possible? Are there gateways to other universes? What happened before the instant of the big bang? How was the Universe created and how will it die? These are cosmic questions and the only way to answer them is with theoretical physics, using the work of Einstein, and quantum theory. Physics, and particularly theoretical physics allows you to answer some of the deepest questions about space and time. What is the appeal of physics, and theoretical physics in particular? Astronomy Now's Kulvinder Singh Chadha talks to the man who dreams about the impossible. Two of his most recent programs were shown on BBC Four and his latest book Physics of the Impossible (Allan Lane, ISBN 9780713999921) is on sale now.

He is a best-selling author and TV presenter. Michio Kaku is professor of theoretical physics at City College New York. These briefings preview the launch and science objectives of NASA's Dawn asteroid orbiter. NASA's Dawn space probe launches aboard a Delta 2-Heavy rocket from Cape Canaveral to explore two worlds in the asteroid belt. Space shuttle Discovery rolls out of the Vehicle Assembly Building and travels to launch pad 39A for its STS-120 mission. The STS-118 crew, including Barbara Morgan, narrates its mission highlights film and answers questions in this post-flight presentation. The highlights from shuttle Discovery's launch day are packaged into this movie.
