Could Transient Radio Signals Indicate Extraterrestrial Intelligence?

AI Thread Summary
The paper discusses the potential of transient radio signals as indicators of extraterrestrial intelligence, emphasizing the need for a shift in SETI techniques towards detecting ephemeral signals rather than enduring ones. It highlights that most detections may be unique and never repeat, necessitating a comprehensive data collection strategy to differentiate between natural phenomena and potential extraterrestrial sources. The author draws a parallel to the scientific rigor used in confirming the Higgs Boson, suggesting that a similar approach is needed in the search for extraterrestrial signals. The discussion underscores the importance of dreamers and innovative thinkers in expanding our understanding of life beyond Earth. Continued exploration in this field may reveal insights into interstellar civilizations.

This paper 'Provocative radio transients and base rate bias: a Bayesian argument for conservatism', http://arxiv.org/abs/1211.7338, discusses transient radio signals as possible signs of extraterrestrial intelligence. I knew of the 'WOW' signal, but, was unaware of other similar detection events.

I thought the "Conclusions" section of the paper was most instructive:

"Conclusions

As SETI techniques begin to turn away from the search for purposefully Earth-directed signals of enduring duration and more toward finding the ephemeral leakage associated with the complex business of maintaining an interstellar civilization, large or small, then we must come to terms with the fact that most if not all of our detections will be one of a kind…never to repeat with exactly the same parametric characteristics or in the same position in the sky. With this in mind it becomes particularly important to collect a large data set of provocative (i.e., possibly indicative of extraterrestrial intelligence) radio transients through a long stare strategy in order to build up a compelling case that they cannot all be explained by natural phenomena in much the same way the dedicated scientists at CERN used their diligence and perseverance to recently claim the Higgs Boson exists to an extremely high degree of confidence. In consideration of this it is important to realize that the finest mathematical sieve will always gather up far more straw from the haystack than it does those very special needles."

It seems that without dreamers like this we may be destined to only know life here on Earth forever.

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
