The Drake Equation is a formula designed to find the number of intelligent civilisations in the galaxy, using
  • The number of stars formed every year
  • Multiplied by the fraction of those stars with planets
  • Times the number of those planets in the solar system that could support life
  • Multiplied by the fraction of those planets on which life appears
  • Multiplied by the fraction of those life-bearing planets on which intelligence arises
  • Times the fraction of those that would become technologically advanced with a desire to communicate
  • Multiplied by the length of time that they continue to transmit detectable signals into space
What is the Equation and do you think this is true?
