The Eerie Silence

I'm still working my way through the new Paul Davies book: The Eerie Silence- Renewing our Search for Alien Intelligence. It's starts as a good review of the basic challenges of SETI. The meat of the text is his call for a new way of approaching SETI. Many astronomers agree that searching for radio waves might be a bit narrow of an approach. Our own society is quickly advancing away from radio wave technology, so why should we be searching for radio signals? SETI has expanded to included laser and other light beam searches. Davies argues for more out of the box approaches that push our understanding of physics and challenge the limits of our technology. The book has been well received and I look forward to finishing soon.
