It’s no secret that I enjoy reading the scientific musings of Professor Paul Davies, so I’m definitely looking forward to getting my hands on this new paper, titled “Footprints of Alien Technology“. In it, Davies suggests that we should not be blind to the possibility that there may be traces of alien technology to be found on Earth or elsewhere in our own Solar System:
If alien civilizations do, or did, exist, their technology will impact their environment. Some consideration has been given to the detection of large-scale astro-engineering, such as Dyson spheres. However, a very advanced technology might leave more subtle footprints requiring sophisticated scientific methods to uncover. We must not overlook the possibility that alien technology has impacted our immediate astronomical environment, even Earth itself, but probably a very long time ago. This raises the question of what traces, if anything, might remain today. I shall consider the possibilities of biological, geological and physical traces, and suggest ways that we might search for them.
Unfortunately, to read the full article you’ll have to purchase it, for the low, low price of just $31.50 (making this article today rather timely). If anybody has seen a copy floating through the internet tubes, be sure to let me know… [update: I have a copy now – Grailsourced!]
In the meantime, check out this review of the article at Space Archaeology, which adds some context via links that are worth following.
