| Summary | The theory proposes that the unusual dimming patterns of star KIC 8462852, known as Tabby's Star, could be caused by an artificial alien megastructure such as a Dyson sphere or swarm. Proponents argue that the observed luminosity dips are not easily explained by natural phenomena. However, subsequent analysis by over 200 astronomers indicates that the dimming is consistent with dust and other natural causes. |
| Origin | The theory emerged in 2015 after astronomer Tabetha Boyajian and colleagues discovered the star's irregular dimming events, and some scientists suggested an alien megastructure as a possible explanation. |

| Evidence / consensus | The scientific consensus is that the dimming is most likely caused by dust from a disintegrating comet or other natural debris, not an alien megastructure. A comprehensive study involving over 200 astronomers found no evidence of artificial structures. |
