It wasn’t until a lunchtime conversation between astrophysicists that doubt was cast upon the old theories, and the outcome of that conversation continues to challenge even contemporary mind-sets. Type II civilizations can control and channel all the energy of their host star, and Type III civilizations have access to power equivalent to that of their host galaxy.Įven before the Drake equation and the Kardashev scale, many scientists were convinced that there must be a plethora of intelligent civilizations sprinkled across the galaxy.

Type I civilizations are able to use all the energy available on their home planet (we are approaching this most scientists agree that we are currently at a 0.7 on the Kardashev scale, with a full Type I being about a century off). To break these numbers down further, scientists use the Kardashev scale, which splits intelligent life into three categories. We as a civilization have been broadcasting into space since 1974, so, according to this equation, even if we cease to exist as a species in 2074, there would be 10 intelligent civilizations in our galaxy alone. The commonly cited numbers for these variables simplify the equation to N = 10 × 0.5 × 2 × 1 × 0.1 × 0.1 × L, which simplifies even further to N = L/10. R * is the rate of formation of stars that could potentially allow for the development of intelligent life on planets nearby f p is the fraction of said stars that actually have planetary systems n e is the number of planets in a solar system with an environment that could sustain life f l is the fraction of said planets that do sustain life f i is the fraction of life-sustaining planets on which there is intelligent life f c is the fraction of intelligent civilizations that have survived long enough to develop communication technology to send signals of their existence into space and L is the length of time that these civilizations emit these signals before ceasing to exist. The equation aimed to find the number ( N) of intelligent civilizations within the boundaries held by the subsequent factors-in our case, the Milky Way Galaxy. In 1961 physicist Frank Drake developed a mathematical equation to help solve it: Scientists have explored this question for years. There are many questions we ask ourselves when looking toward the heavens, but one of them always feels just outside of our grasp: Across all the billions of light-years of starry sky above us, could we possibly be the only life? Humanity time and time again finds itself lost amid the vastness of a universe that we are still struggling to understand. On a clear night, staring up at the stars induces a sense of simultaneous wonder and insignificance.
