Ancient structures possibly built by early hominids raise many of the same puzzles as our quest for life elsewhere does
This post is one in a series covering, and expanding on, topics in the book The Copernicus Complex (Scientific American/FSG). The conversation usually goes like this: Do you think we’re alone in the universe?
Astronomers hope that one day soon we’ll obtain a spectrum of light that might tell us whether or not an Earth-sized exoplanet harbors life.
Probably not, but just possibly yes. One of the reasons that the search for life elsewhere in the universe is so exciting is that it would take only one chance discovery, one lucky break, for all the walls to come tumbling down.
A recent article by Samuel Arbesman in the science magazine Nautilus discusses the extraordinary sounding possibility that – just perhaps – a search for extraterrestrial intelligence could be made by looking at our DNA.
New studies indicate that ionizing radiation might cause neurodegenerative disease. The implications could be profound for interplanetary or interstellar species.
In a month’s time, the end result of two-and-a-half years of research, thinking, writing, re-writing, re-re-writing, editing, mulling, puzzling, coffee-drinking, beer-swilling, swearing, and tweaking will hit the shelves in the form of my new book The Copernicus Complex.
