• Resumen

  • Grossman talks about an iconic tool in the search for extraterrestrial life. The new tool takes the form of an equation. In 1961 astronomer Frank Drake scribbled his now famous equation for calculating the number of detectable civilizations in the Milky Way. The Drake equation includes a number of terms that at the time seemed unknowable--including the very existence of planets beyond the Earth's solar system.
