Little Book of Aliens, The

Everyone is curious about life in the Universe, UFOs and whether ET is out there. Over the course of his thirty-year career as an astrophysicist, Adam Frank has consistently been asked about the possibility of intelligent life in the universe. Are aliens real? Where are they? Why haven't we found them? What happens if we do? In this small book with big stakes, Frank gives us a rundown of everything we need to know, from the scientific origins of the search for intelligent life, the Fermi Paradox, the Kardashev Scale, the James Webb Telescope, as well as UFOs and their conspiracy theories. Drawing from his own work and that of other scientists studying the possibility of alien life, he brings together the latest scientific thinking, data, ideas, and discoveries to equip us with the critical facts as we stand at what may be the last moment in human history
