The Drake Equation and How It Helps SETI
December 1, 2009
In 1960 Dr Frank Drake attempted to create a way to guess how many intelligent civilizations like our own would arise in our galaxy and in the universe. The question of if we’re alone has driven astronomy and space exploration for centuries and is one of the greatest unanswered questions we have left.
What Drake wanted to do was to try and work out how likely it was that we’d ever make contact with another civilization, or if the probability of intelligence arising was so remote that we’d spend our time very much alone. The result of his attempts is the now famous Drake Equation, the formula that essentially powers SETI and helps astronomers to focus their searches for artificial signals in the universe.
