Are We Alone?

BBC Four - Human Universe, Are We Alone?

Brian considers the possibility of alien life - could it exist and will we ever find it?

Professor Brian Cox explores mankind's place in the universe. He considers the possibility of alien life - could it exist and will humans ever find it?

Brian Cox explores the ingredients needed for an intelligent civilisation to evolve in the universe - the need for a benign star, for a habitable planet, for life to spontaneously arise on such a planet and the time required for intelligent life to evolve and build a civilisation. Brian weighs the evidence and arrives at his own provocative answer to the puzzle of our apparent solitude.
