Type 3 civilization (Hoag object ring galaxy photo)
Continuing our earlier Carl Sagan civilization post, today’s photo is Hoag’s object, a non-typical ring galaxy. A type III civilization would, be definition, be able to harness the entire energy of a reference galaxy. We left off earlier on the important wrinkle that Sagan added to the Kardashev scale on civilization advancement (and, by extension, the Leslie White scale on historical civilizations). Both of these scales focus on technology (with Kardashev focused on technology to harness energy), but Sagan also added information processing (data science!) to the scale. He defined a scale from A-Z to represent the amount of information available to a civilization, each letter representing a 10-fold increase, with A representing 10^6 and Z representing access to 10^31 bits of information. Sagan believed no civilization could yet have achieved a Z status, as not enough time had passed in the history of the universe to allow this much exchange of information.… Read the restPhoto of Earth by Nasa? Nope. Astroengineering.
Is this a photo of Earth by Nasa? Nope. In this artist’s conception, the Moon is geoengineered/astroengineering by an advanced civilization to be more like Earth. Will inducing artificial earthquakes through geoengineering or someday save lives, or is it too dangerous? Will we someday geoengineer the and the stars, as discussed on recent science documentaries? These were discussed in our earlier blog post on fracking and geoengineering, for which this was the featured image.
