How to spot an alien megastructure
THERE comes a stage where any innovative alien civilisation worth its salt must dismantle a neighbouring world for spare parts. This is not a act of vandalism, you know, but instead a precursor to creating an huge solar energy plant which encircles its whole host celebrity. What else could an ambitious alien society do to keep its growth? How else could it fulfill its ever-increasing requirement for energy?
This situation, or something similar, is the foundation principle of the hunt for alien megastructures, which in this instance might appear something like dark embers when seen via infrared telescopes. The research started in 1960, when physicist Freeman Dyson suggested it as a means of finding extraterrestrial life. Over 60 decades later, the search for Dyson spheres, since they’re now understood, remains a minority game one of people involved the hunt for extraterrestrial intelligence (SETI), a venture that has focused mostly on listening to radio signals from different worlds.
However, astronomers are still prospecting for signs of alien technologies. Specifically, they’ve been working to set the pursuit of Dyson spheres onto a strict scientific foundation. They are poring on the very exact cosmic cartography ever made to attempt and locate stars which may be encompassed by swarms of solar panels and differentiate them from naturally occurring infrared herrings.
