What We Still Don’t Know: Martin Rees Tackles Deepest Scientific Questions in Great Documentary

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).
