Rethinking Dyson Spheres: Thermodynamics, Activity Signatures, and the Practical Search for Megastructures
To the point
Freeman Dyson proposed Dyson spheres as star-enclosing megastructures, and Jason T. Wright argues we should search for activity indicators and practical construction clues, guided by thermodynamics and the Landsberg Limit, rather than relying solely on mid-infrared waste-heat signatures.
