Alien megastructures spark interest in outer space from "summary" of EXTRATERRESTRIAL by Avi Loeb
The idea that alien megastructures could be lurking in outer space has captivated the imaginations of scientists and the public alike. This concept, first introduced by a peculiar star named Tabby's Star, has sparked a renewed interest in the search for extraterrestrial intelligence. The discovery of this mysterious star, which exhibited irregular dips in brightness, prompted speculation that it could be surrounded by a massive structure constructed by an advanced alien civilization. As astronomers delved deeper into the study of Tabby's Star, they considered various hypotheses to explain its unusual behavior. Some suggested that clouds of dust or swarms of comets could be causing the erratic dimming patterns observed. However, these explanations fell short in accounting for the magnitude and consistency of the star's fluctuations. The most compelling theory put forth was the possibility of an alien megastructure, such as a Dyson sphere, constructed to harness the star's energy. The idea of alien megastructur...
