Could you elaborate why not? All current technology I know of has an efficiency of <100%, with waste energy being lost as heat (which in space would be radiated away in the infrared spectrum). Why would this not be the case for a hypothetical dyson sphere or swarm?
- zare_st 3y agoBecause the topic isn't about heat per se but heat signatures and detecting artificial heat signatures across the universe. Of course everything radiates heat I did not think I have to get down to that level in commenting here.
- yreg 3y agoSorry, I don't understand you either. Without new physics Dyson spheres radiate heat. Therefore they are detectable.
