Aliens: The World's Leading Scientists on the Search for Extraterrestrial Life

by Jim Al-Khalili (Editor), Jim Al-Khalili (Introduction)

Overview

In these lively and fascinating essays edited by theoretical physicist Jim Al-Khalili, scientists from around the world weigh in on the latest advances in the search for intelligent life in the universe and discuss just what that might look like.
Since 2000, science has seen a surge in data and interest on several fronts related to E.T. (extraterrestrials); A.I. (artificial intelligence); and SETI (search for extraterrestrial intelligence). The debate has intensified over whether life exists outside our solar system, what that life would look like, and whether we'll ever make contact.
Included here are essays from a broad spectrum of the scientific community: cosmologists, astrophysicists, NASA planetary scientists, and geneticists, to name just a few, discussing the latest research and theories relating to alien life. Some of the topics include: If life exists somewhere in space, what are the odds that it evolves into something we would recognize as intelligent? What will space travel look like in the future, and will it all be done by cyborg technology? How long until we are ruled by robot overlords? (This is actually a serious consideration.) Are we simply a simulation in the mind of some supreme being, acting out a virtual reality game?
For those who have ever wondered, Is there anybody out there? here are the latest theories and evidence that move us closer to answering that question.

Editorial Reviews

…[a] modest, eccentric collection…the best of these essays are far out in more ways than one.

The New York Times - Jennifer Senior

"Superb....An incisive and fun collection packed with mind-expanding ideas about our universe and ourselves."—Kirkus Reviews

“A brilliantly sharp collection.”—The Observer (London)

“Jim Al-Khalili has gathered a useful cross-section of the brightest minds in space science. . . . [Aliens] goes far beyond the what and the where and the when of extraterrestrial-hunting to the biggest conundrum of all: why bother? . . . This book is always lucid and sometimes unexpectedly beautiful.” —The Times (London)

“Ideal for keen alien-fanciers.” —The Daily Mail (London)

"Fascinating...There’s a little something here for anyone interested in the possibility of extra-terrestrial life, or at least how we imagine it to be.”—Spectrum Culture

"A wide array of easily digestible, information-packed essays from researchers writing on various aspects of the search for extraterrestrial life....An excellent primer on various concepts and aspects of potential alien life, and the consequences of such an earth-shattering discovery."—Publishers Weekly

“Thought-provoking… Must-reading for star-watchers, visionary anthropologists, and everyone wondering if and when the ETs will finally pay us a visit.”—Booklist

“Much like Louisa Preston’s Goldilocks and the Water Bears, this book succeeds in looking much deeper than the typical earthbound definition of life….[Aliens] may even be appreciated by curious sf fans and casual readers.”—Library Journal

From the Publisher

2017-03-07
In a series of 20 essays detailing cutting-edge scientific data and theories, renowned researchers expound on the possibility—or probability?—of extraterrestrial intelligence.In February 2017, NASA announced the discovery of seven Earth-sized exoplanets orbiting a single star, three of which are located in the habitable or so-called "Goldilocks Zone," meaning their atmospheres are more likely to host life. Located a mere 40 light-years from Earth, these planets especially excited scientists because they are near enough to study using high-tech space telescopes. This means that humanity may have an opportunity to confirm or deny our sole existence in the universe—a proposition that, based on the number of planets and stars in our galaxy alone, seems unlikely. Yet no experiment has produced even a shred of evidence of any other life form (that we can detect). In this superb collection of essays, editor al-Khalili (Theoretical Physics/Univ. of Surrey; Paradox: The Nine Greatest Enigmas in Physics, 2012, etc.) assembles some of the most brilliant minds in astrophysics, cosmology, genetics, biochemistry, and other fields to provide lay readers with a comprehensive look at the search for life on other planets. From new technologies in spectroscopy to the much-anticipated James Webb Space Telescope, scheduled to launch in 2018, there are many ways in which researchers have their eyes to the deep skies. Equally fascinating are the different perspectives regarding how such life could arise: are carbon and liquid water integral? How might plate tectonics play a role? Could quantum mechanics explain how life emerged on Earth, and could it do so elsewhere? Each essay offers a unique take on these and myriad other probing questions, and as al-Khalili writes in his introduction, "thinking about extraterrestrials has led us to ask, and even begin to answer, some of the most profound questions about our own existence." The contributors include Martin Rees, Ian Stewart, and Monica Grady. An incisive and fun collection packed with mind-expanding ideas about our universe and ourselves.
