It’s been 50 years since Nikolai Kardashev proposed his eponymous scale for ranking hypothetical civilisations based on their energy consumption. We take a look at its theoretical and practical impact, and how it’s still influencing SETI today
Finding extraterrestrial intelligence would be one of the most enlightening and profound discoveries in history. Today’s post looks at two potential means of finding extraterrestrials by seeing their advanced technology elsewhere in the Milky Way and the Universe.
Researchers at Penn State aim to determine the probability that artifacts from allien civilizations are present in our Solar System.
In this paper, the authors attempt to use Bayesian statistics to estimate the frequency of extraterrestrial life (and derive a fairly inconclusive result).
The authors consider a possible signature of an intelligent, spacefaring life form, more technologically advanced than ourselves: they consider the effects that significant asteroid mining would have on a debris disk and determine whether these effects would be observable.
