What Are Alien Megastructures? Extraterrestrials Harvesting Energy

TL;DR

Astronomers investigate strange dimming of star, propose alien mega-structures as a theoretical explanation.

Transcript

in summer of 2015 astronomers announced a strange new discovery for nasa's planet hunting Kepler space observatory some object was blocking out about 22% of the light from its parent star KIC 846 - 8 5 - even the largest planet in the solar system Jupiter will only block out 1% of a star's light so something much larger must be doing this but what ...

Questions & Answers

Q: What led astronomers to consider alien mega-structures as an explanation for the dimming of KIC 846-85?

Astronomers ruled out conventional explanations like comets, leading them to contemplate extreme possibilities such as alien mega-structures to block out such a significant amount of starlight.

Q: What are Dyson Spheres and how do they relate to the concept of alien mega-structures?

Dyson Spheres are theoretical mega-structures that would encapsulate a star to harness its energy. They represent one form of alien mega-structures proposed by scientists to explain advanced extraterrestrial civilizations.

Q: How do astronomers search for evidence of alien mega-structures in the universe?

Astronomers carry out surveys looking for anomalies like stars dimmed by mega-structures, specifically focusing on infrared radiation that would leak out of a Dyson Sphere, providing potential clues to their existence.

Q: What does the gradual dimming of KIC 846-85 over a century imply about the alien mega-structure theory?

The gradual dimming observed rules out transient phenomena like passing comets, lending more weight to the alien mega-structure theory, although it remains a highly speculative explanation.

Summary & Key Takeaways

• In 2015, astronomers discovered a star, KIC 846-85, being dimmed by an unknown object blocking 22% of its light.

• The concept of alien mega-structures, like Dyson Spheres, is proposed to explain the phenomenon.

• Despite being highly improbable, the search for alien mega-structures continues with advanced astronomical surveys.
