I love this... So much hope :) The search for Dyson spheres was happening. Here are summary of results so far: https://home.fnal.gov/~carrigan/infrared_astrono

- danieltillett 9y agoNot too likely to work if the builders know anything about making an efficient Dyson sphere [0]. 0. https://www.tillett.info/2016/08/03/carnot-efficient-dyson-spheres-are-undetectable-by-infrared-surveys/ https://www.tillett.info/2016/08/03/carnot-efficient-dyson-s...
- JamesLeonis 9y agoI think it's more likely than you credit. I expect that Dyson spheres "in the wild" would exist on a continuum of inefficient to efficient to decayed. An inefficient sphere might exist under these conditions: * Still under construction * Inefficient sphere built previous to efficient spheres * A civilization is just learning how to build one * A ruined structure from a dead or regressed civilization
- danieltillett 9y agoA sphere (swam more likely) that is under construction/damaged/ruined would leak a large amount of light at high wavelengths. A 290K infrared survey is not going to pick up one of these structures. It reminds me I need to finish my post on how to actually find Dyson spheres.
