Avi Loeb's Extraterrestrial: Investigating the First Sign of Intelligent Life Beyond Earth

Chris Horne: Wanting more. My hope is that more people will read this book and then study the evidence supporting human amplification of climate change so that more deep space probes can be launched to find evidence of life beyond earth.

nancy clayton hoover: I thoroughly enjoyed this book by Avi Loeb. I found it easy to read and very interesting. Well written for those of us who are not astrophysicists. I hear Oumuamua is coming back! Hopefully we can learn more. Thanks for a great book!

Kevin Stack: Book came from momox in the Netherlands took quite a while probably due to brexit.

JD: Haven't learned anything that I didn't already know about Oumuamua. I had bought it to learn more but for every 1 page of scientific info, there's 2 about Avi Loeb reminiscing about holidays with his family.

Also, the diagrams are so small that you need a magnifying glass.

Very disappointed!

Carla: Very interesting book! I didnt expect for it to be so interesting and very well explained. The contents relating to physics is very easy to understand even if you have no knowledge about the topic.

Jonathan Hornig: I thoroughly enjoyed this book, it was fresh from the writings of a harvard astrophysicist, who knows first hand the ins and outs of scientifical data regarding the “first sign of intelligent life beyond earth”. He tells you what you need to know about this most likely atrifical object, and gives am intricate analysis of the possibilities of it being a natural phenomena. He dives into the peculiarities combined with how a natural explanation would contrast the views of thia alleged phenomena, that if we know it was coming would unequivocally solve the answer to this debate. He doesnt go into the much deeper of extravagance detail analysis of scientifical data that would bore you, but he finds a way to articulate the pertinent rationale of what you necessarily need to hear, since much of the data on this phenomena sways to the other equation, when in fact, it shouldnt. But a very interesting read, from thought experiments to his own opinionated conclusions, makes this a well worth buy and a must read if your into this kind of writing. Also, this non fiction seems like a prelude to his upcoming book being released in just a couple months that will also probably be a must read!!...

Barry Cottrell: It’s a super interesting book about a really important topic. But the way avi writes does not flow well. He is a physicist not a writer. And it shows. Still. He is right and the world needs to think more like Avi.

Dr. Hugh Deasy: Not only does Avi reveal more details of the unusual not to mention unique aspects of Oumuamua than any other researcher, but he also discusses at length what is wrong with the current academic attitudes to truly challenging phenomena. First using the example of Oumuamua, he shows that there are 6 or more unique aspects to the case, and not just 2 or 3 as most researchers maintain. The latter seem to be seeking to play down the truly challenging aspects of the case. This is because to admit all the challenging aspects would be to show that the evidence points clearly, using Occam's razor, to a 91% probability of an extraterrestrial technological nature of the object. And the ET hypothesis is shown to need less extreme concatenations of events than proposals for a natural origin: the latter include hydrogen ice just enough scraped off a hydrogen ice planetoid. The number of such unusual objects that would have to be produced makes it extremely unlikely that we would have observed one of these in the lifetime of the galaxy. It is calculations of this sort that are the stuff of good research and this is what this book exudes in every page. So if you are of a scientific leaning then...

Theodore A. Rushton: 'Extraterrestrial' by Avi Loeb is interesting, if true. Fascinating, if this 'First Sign of

Intelligent Life Beyond Earth' is eventually resolved to be an error - - because a hundred-and-one

(and even more errors) always mark the steps to uncovering new truths.

Good scientists seem to thrive on "mistakes." When Thomas Edison was asked about

his thousands of attempts to make a lasting electric light-bulb, his response was that he'd learned

"a thousand ways not to do it."

In brief; Loeb provides a fascinating example of how science really creates new

knowledge. In addition, he taps into the costly curiosity of the human species - - "Let's go see

what's on the other side of the hill." His example is the most relevant (in my humble opinion)

topic in current science: How do we go about discovering whether or not humans are alone in the

Universe, or if other sentient beings are at or beyond level our intelligence and empathy.

Fortunately, he doesn't wander into the ethical issue: How to do we respond if "other

life" is vastly superior to our humble talents? or, would 'superior' beings from distant stars...

G. C. Carter: The book entitled: “Extraterrestrial: The First Sign of Intelligent Life Beyond Earth” by Avi Loeb was fascinating and compelling on several fronts.
Professor Loeb begins with writing: “When you get a chance, step outside and admire the universe. This is best done at night, of course. … Just looking up, I find, helps change your perspective.” Moreover, he states: “This book confronts one of these profound questions, arguably the most consequential: Are we alone?” The author reminds us: “The world will end, of course, and most decidedly with a bang; our Sun, now about 4.6 billion years old, will in about 7 billion years turn into an expanding red giant and end all life on Earth. This is not up for debate, nor is it an ethical matter.”
As Professor Loeb states: “I remind my students that, as Galileo Galilei argued after looking through his telescope, evidence doesn’t care about approval.” The author goes on to set the stage “Contemplating the sky and the universe beyond teaches us humility. Cosmic space and time have vast scales. There are more than a billion trillion sun-like stars in the observable volume of the universe, and even the luckiest among...
