Scientists have identified 60 stars with unexplained infrared excess that cannot be explained by known natural processes. Original post
"Type 2 civilization doesn't just live on a planet. They harvest their entire star. We used to think this was just science fiction. But physicists realize something. You can't hide a machine that big. The second law of thermodynamics says energy cannot be destroyed. It becomes heat. A Dyson sphere must leak infrared exhaust. If you see a star that is invisible in light but screaming with heat, you found a megastructure. A research team named Projekt Hephaistos at Uppsala University in Sweden just scanned 5 million stars looking for this exhaust signature. They didn't find zero. They found seven. In fact, scientists throughout the world have discovered a total of 60 stars matching this profile. If they are Dyson spheres, what do they use all of this energy for?"
