If the Universe Is Teeming with Aliens ... WHERE IS EVERYBODY?: Fifty Solutions to the Fermi Paradox and the Problem of Extraterrestrial Life

by Stephen Webb

In a 1950 conversation at Los Alamos, four world-class scientists generally agreed, given the size of the Universe, that advanced extraterrestrial civilizations must be present. But one of the four, Enrico Fermi, asked, "If these civilizations do exist, where is everybody?" Given the fact that there are perhaps 400 million stars in our Galaxy alone, and perhaps 400 million galaxies in the Universe, it stands to reason that somewhere out there, in the 14 billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. Webb discusses in detail the 50 most cogent and intriguing solutions to Fermi's famous paradox.



A few real reviews for the book on Amazon:


Science and science fiction collide to pose answers to a fundamental question about our universe

If the universe is so old and so big, shouldn't there have been ample opportunities for other solar systems, planets, life forms, intelligence, and technology to form? Some these civilizations must be millions of years older than us on Earth, so surely should have developed the capability to communicate and travel through from star to star and galaxy to galaxy. But we haven't heard from or seen anybody else. Where is everybody?
This a big and provocative question that has scientific, philosophical, and religious implications. Webb breaks the question down by posing 50 possible solutions to this paradox. He brings in concepts from physics, astronomy, chemistry, biology, history, geology, science fiction, sociology, cognition, and engineering. To think about this question involves the combination of so many disciplines, and that's why it's so very intriguing. Not only that, our best answers are at the frontiers of most of these fields of knowledge. So, in this book you get a whirlwind tour of the biggest thinking, cutting edge, and open questions in so many different areas. I recommend this book to science lovers and science fiction lovers.




Billions Of Channels And Nothing's On?!?

Four guys walk into the caf at Los Alamos for lunch and start discussing extraterrestrial intelligence. They decide that life, intelligence, and conquering the galaxy shouldn't be that hard. Then one of them asks, "where is everybody?" Far from being the beginning of a bad nerd joke, this lunchtime discussion actually took place in the summer of 1950 and Enrico Fermi really did ask the now famous Fermi Question. The discussion and question led to the Fermi Paradox: if the universe is as old as it is, and if the Earth isn't the oldest planet with intelligent life, and conquering the galaxy is as easy as it seems, then where the heck are they?

Physicist Stephen Webb does an admirable job of discussing some possible answers to the Fermi Paradox in If The Universe Is Teeming With Aliens...Where Is Everybody?: Fifty Solutions To The Fermi Paradox And The Problem Of Extraterrestrial Life. It's a tough job, even for a fan of the Fermi Paradox like Webb, since it means being well versed in a wide range of subjects AND it means thinking like an alien intelligence. Webb describes and critiques 49 of his favorite solutions, starting with They Are Here And They Call Themselves Hungarians, and then throws in a fiftieth solution of his own design.

The solutions are subdivided into three sections:
1) They Are Here,
2) They Exist But Have Not Yet Communicated, and
3)They Do Not Exist.

The book is set up so that after reading Chapters 1 and 2, a person can read the solutions as they wish. Some basic math and science skills are required, but the book should be accessible to a wide reading audience.




Well Made - Works Great

This is my second Ruff Riders harness, the other one is a large. This one hold the dog securely and is made very well. Getting it on the dog takes some practice, but I like the fact that there are no plastc connectors to break if there would be a car accident.
