Where Are They? And why haven’t we found them yet? by Steven Lazaroff and Mark Rodger
This could be the best non-fiction book I’ve ever read.I bought this book because I had previously bought and enjoyed History’s Greatest Deceptions and Confidence Scams. That book wasn’t perfect, but it was good enough that I wanted to see what they’d written next. And I am so glad I did. Where Are They? shows what happens when writers gain confidence in what they are doing. This book soars to the heights – both in its subject matter and literally, as a masterpiece in conveying information.
The title comes from physicist Enrico Fermi who said, about theories that Earth should already have received extraterrestrial visitors and yet no convincing evidence of a visit existed, “Where is everybody?” The universe should be teeming with civilisations at one level of development or another – so where are they?
The book examines all the current theories that have been developed to answer this question. It takes no sides. It simply sets out the present state of knowledge. But it does so in the most brilliant, beautiful prose. So brilliant that I would recommend this book even to readers with no interest in the search for alien intelligence, simply because they will enjoy the limpid prose and the humour with which the arguments are presented.
Here is an example:
‘Imagine that you are in the same position as one of those alien astronauts being tapped up for a journey to Earth from the galaxy MACS0647-JD. It’s 13.3 billion light years away, so – if your civilisation has developed a form of transportation that will travel at the speed of light – the time spent on the journey is unimaginable. Would you want to do it? Leave the kids, your husband and your book club knowing that at the end of your journey you would encounter a civilisation a few hundred millennia less developed than yours? And that you couldn’t get home for nearly 27 billion years at the earliest, by which time your planet would in all possibility have come to the end of its life? And that, when you arrived on Earth, your body would have been renewed some eighty times, so you wouldn’t really still be you at all?’
Not a single prominent theory about the evolution of life forms has been left out. It’s also clear that the authors take a dim (they would probably say “realistic”) view of humanity’s fitness to receive visitors from another civilisation.
I’ll say it again: this could be the best non-fiction book I’ve ever read. Do yourself the most amazing favour and READ IT.
