ASTROBIOLOGY – The search for life | SPACETIME – SCIENCE SHOW
Are we alone? A question we ask ourselves every time we gaze deep into the endlessness of space. And the dream of discovering the origins of mankind is as old as civilization itself. Are there other worlds that support life? Or is the earth merely a cosmic accident?
What in fact is life? What forms of life are there? And what constitutes higher intelligence? And most importantly: What are the prerequisites for the emergence of life? We naturally need solid ground under our feet – i.e. a planet – with an atmosphere and the right temperature, but the question is: How many earth-like planets are there out there? Or is the earth unique? And crucially, if there are a lot of earth-like planets, how likely is it that higher forms of life evolve on them?
