Publisher's Summary

In these lively and fascinating essays, 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 ET (extraterrestrials); AI (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 in this audiobook 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.

    "Space...................lots of space in space"

    Good info and solid science, gets you thinking about how small we really are in this universe....a spec on a rock circling a star in a sea of other stars with their circling rocks all rotating around a black hole, but wait...there are billions and billions more all doing the same thing too?!?! What a sick joke...space has too much space in between for us to travel or even try to communicate with any other life.
    The big question is...where did this all come from, smart people back track things using evidence dug up along with some smart science but what was here before the Big Bang and what made the Big Bang happen!?!? Who or what made space and everything in it!?!?

    Story
    "Very Interesting; Poorly Fact-Checked"
    If you could sum up Aliens in three words, what would they be?

    Intriguing, worrying, and frustrating. The first two are both meant in a good way. For an explanation of the last, see below.


    What did you like best about this story?

    The realism w/ regard to the likelihood of alien civilizations.


    What does the narrators bring to the story that you wouldn’t experience if you just read the book?

    The ability to consume the book while driving? For something like this, audiobook format is probably objectively worse.


    Was this a book you wanted to listen to all in one sitting?

    No.


    Any additional comments?

    A significant portion of Chapter 14 (Chapter 15 in the audible file) is devoted to arguing that eukaryotes/eukaryote-equivalents are likely quite rare because endosymbiosis has only occurred once (Mitochondria). After five minutes of building on that argument (during which I was getting angrier and angrier) the author of that chapter admits that it has actually occurred twice (the second time being Chloroplasts), which completely undermines the prior five minutes *and is still wrong.* Endosymbiosis of cyanobacteria, creating chloroplasts, has happened at least twice that we know of, and it may well have occurred more times than that.

    I guess I'm just frustrated they wasted so much time and space on a crappy argument for the lack of complex life on other planets, and that they oversold it so badly.

    "Thought Provoking"

    Exploratory in nature. Exercise in thinking whether our species has the time frame and reasoning ability to comprehend the idea of extra terrestrial life.

    Story
    "What science thinks of extraterrestrials"

    Don't be deceived by the title. This book is the science of detecting life in other planets. It does touch on some science fiction and our fantastic imaginations, but very quickly quells any proof of "aliens" as depicted by movies, books, and conspiracy theories.

    Saying all the above, this is still one of the most fascinating collections of scientific thinking on what might be out there and possibilities of life in other planets.

    It takes an Al-Khalili to bring those true scientists to talk about this subject as most have shunned away from the subject and for good reason. We cannot identify something that we can't define, and believe it or not, life is defined differently by many in science. In fact if there is one thing in common, it is that life cannot be defined.

    Still, this book better than many others gives the perspective of many scientists, and gives a good foundation where the reader can make his own decision. Like consciousness, unfortunately there aren't many ways that can decisively prove that life exists beyond earth, and those nay sayers will always have the upper hand.

    I would like to think we are progressive and open minded to understand that we may not be so special, and other life exists. Or that life is beyond our narrow interpretation of it, and this book brings hope.

    Excellent collection of scientific thoughts on the subject. Highly recommended to anyone interested in science and too fixated on everyday chores.
