If the Universe is Teeming with Aliens…Where is Everybody?: Seventy-Five Solutions to the Fermi Paradox and the Problem of Extraterrestrial Life [2015] – ★★★★1/2  

I am continuing with my Non-Fiction November Reading Challenge with this curious book on the Fermi paradox. This paradox states that, if there are billions of stars out there in galaxies, and they are similar to and much older than our Sun, there is a high probability that those distant systems have planets that resemble our planet Earth. In turn, the typical nature of our planet means life must have developed and accelerated on other planets too, and, if beings there developed interstellar travel, they should have visited Earth already (or at least sent their probes). The paradox is that we do not see/perceive any extraterrestrial activity. Dr Stephen Webb is a theoretical physicist who proposes and discusses seventy-five solutions to the Fermi paradox in this book, solutions which he divides into three sections: (i) Alien Are (or Were) Here; (ii) Aliens Exist, but We Have Yet to See or Hear from Them; and (iii) Aliens Do Not Exist. This is an enjoyable, mentally-stimulating book that impresses with the number and diversity of different solutions and theories that may explain the Fermi Paradox.
