Are we alone in the universe? A review of the Drake Equation

Wilson da Silva


 We know the probability of intelligent life in the universe is greater than zero – after all, we’re here! But is life a rare occurrence in the cosmos? Is intelligence (and civilisation and technology) just a freak event, never to be repeated? Or does it happen often enough that the universe is humming with the chatter of alien civilisations? Science journalist Wilson da Silva takes a modern look at the Drake Equation, science’s attempt to determine the number of extraterestrial civilisations out there today.
