The Eerie Silence: Renewing Our Search for Alien Intelligence by Paul Charles William Davies
My rating: 3 of 5 stars
This was an engaging, enlightening but in the end almost depressing book. Beside the awesome physical impediments of distance and time to preclude meaningful communication with an alien civilization, Davies etches deeps the facet of this issue I have considered before: a civilization possibly a million years older than ours may be so advanced as to be incomprehensible/undetectable. Our radio telescope basis assumes primitive and lossy communications by others. We may as well use smoke signals.
Intriguing to me is the author's suggestions to look for alien artefacts, beacons. and extraterrestrial microbes thriving in extremeophile conditions or even common ocean water.
