Good enough analytically-Not as sharp as the Docuumentary 14 octobre 2013
Par spudboy100 - Publié sur
Format: Format Kindle Achat vérifié
It is a military science sort of book, that uses the results of other studies, to buttress the analysis which is all good, in my opinion. My only issue is that, of course, this work as a bit drier than the documentary, which had some rally nice computer animation. I am also, not, convinced, that a superior civilization, could not, through agriculture, or more likely, massive, industrial, biosynthesis, produce enough chlorophyll, and protein for themselves. This was one of the draws on why would beings/AI expend lots of energy to come here to conquer or exterminate?

From a cost-price comparison just the human species, for example deciding it required protein and chlorophyll, could with just a few technical advances, produce it massively. It would cost up the yang, compared to farming, but if we required teratons of it, yeah I suppose we could? Slow traveling aliens (10% of light and under) might escape our attention on their approach to Earth, but something traveling, fast, requires a high energy maser, or laser, or antihydrogen. It would produce curious visual, infrared, and radio signatures on Earth's telescopes, even from light years distant. I liked this book quite a lot as a well-reasoned thought experiment, and since we are near the anniversary of Orson Welles Mercury theatre broadcast of Well' War of the Worlds, 1938, it is not a bad read.

Disappointing read -- poorly researched and written 22 septembre 2011
Par m888 - Publié sur
Format: Broché
I was looking forward to this book, as the premise "Should we consider that extraterrestrials may be hostile?" is interesting. However, I found the book poorly written and researched.

Some particularly incredible moments are in Chapter 3 (Motivators), which lists reasons aliens may conquer us including "looking for new sexual partners... to avoid the weakness of the populace caused by inbreeding" and "seeking religious freedom". Seriously? The authors devote Chapter 6 to an amateurish design for a Sixth Column secret defense network, I will spare you the more lurid writing but it does include insightful decisions like the need for a zero tolerance policy for drug abuse and cheating on spouses.

The authors have an annoying habit of including a mathematical equation and then treating the results as proven without any critical thought. On p. 22 the authors conclude the earth can support a population of 100 billion people which will be reached in 10 million years. This conflicts with more thoughtful answers to this important question, and the difference would be interesting if there was some thought behind the authors' assertion. But their justification is a trivial exponential equation and graph, after which they cheerfully apply the same exponential function to explain that aliens would seek to conquer us for population growth space. I would like to see discussion of economic questions, such as whether the collosal energy cost of moving tens of billions of creatures across instellar distances is an effective way to free up real estate.

Weak reasoning aside, the writing style is almost a caricature of an untalented academic, with constant space-filling platitudes such as "These arguments and other arguments should be carefully dissected and considered" (p 159). At times the authors assign homework to the reader such as creating discussion groups.

The premise of the book is on the fringe of science fiction, but I did hope for some serious science and and perhaps even some tongue in cheek moments. Instead I found it hard to read and alarmist. I'd stick to high quality science fiction on this topic, it is more entertaining and has better science.

A MUST READ!!!!! 27 août 2014
Par Dr. Leonard C. Holifield - Publié sur
Format: Broché Achat vérifié
This is a serious work on "What If" the earth is invaded by visitors from another world. It is an in-depth scientific study on the possibility of earth coming in contact with "hostile" aliens from another world and how we would deal with such a threat. The authors Drs. Travis S. Taylor, Ph.D and Bob Boan, Ph.D are both scientise and physicists with expertise in both defense and military signal intelligence and experience working with both the Department of Defense and NASA.

Very informative!

What if they're wrong? 13 novembre 2013
Par Pen Name - Publié sur
Format: Format Kindle Achat vérifié
Conventional & accepted wisdom holds that the chances of hostile alien contact are negligible, fermis paradox etc is quoted. But what if they're wrong? What if by chance the unthinkable happens? Having read this book well I believe that the truth is more frightening that whatever Hollywood can churn out, as an academic exercise it's intriguing but we must ask, do world governments take this seriously? Should they? & if so do they have plans? You decide. The X-Files this is not.

Pretty good, but can be tedious... 25 juin 2011
Par Dave In Ohio - Publié sur
Format: Broché Achat vérifié
The authors write well and present in one place most of the ideas that sci-fi fans and other imaginative people have long pondered.

A number of readers will be put off by the excessive math in the first few chapters, but they should persevere.
The authors seem very anxious to demonstrate that they are Real Science Guys by presenting a lot of Real Science Stuff . Drake's famous equation and others could be clearly discussed and all the variations, proofs, etc., relegated to an appendix for study by the Ubergeeks. Some of this need to parade their smarts before the reader actually gets to be kind of funny as in an aside in the chapter on weaponry: "RF weapon systems can be modeled using Maxwell's equations and either the Lorentz force law (for the kinetics of individual charged particles) or the Navier-Stokes compressible fluid equations (for the dynamics of a conducting gas). The resulting nonlinear system of partial differential equations is analytically intractable, and their numerical solution requires fine grained resolution." But then, you probably knew that, didn't you? And no, it doesn't get any clearer when read in context.

Fortunately the authors do spend a good portion of the book writing to express rather than impress. They quite correctly point out that assuming any aliens that show up are peaceful is just plain silly. SETI is rightfully derided as naive in their efforts to signal extraterrestrials. I side with the scientist I once heard say "If the intergalactic phone rings, don't answer it!"

The section on who really "needs to know" about captured aliens, UFO's etc., may bruise your ego but displays impeccable logic.

Pretty good read. It'll make you think.
