Episode one: 'Are We Alone?'
"The Universe is still a place of mystery and wonder," says cosmologist Martin Rees in this three-part series from Channel 4. "With each advance, new questions come into sharper focus."
What We Still Don't Know was first broadcast in 2004. It won a British Indie Award the following year for best science documentary. Directed by Srik Narayanan and narrated by David Malone, the series offers a fascinating look at some of the most fundamental questions in science -- or indeed, in life. "Are We Alone?" (above). "Why Are We Here?" and "Are We Real?" (Both below).
