Maybe stars are the Dyson spheres, and their emissions are the waste energy that wasn't worth harvesting.

- wizzwizz4 5y agoThe spectral signature would be different if that happened. If all of the stars are Dyson spheres, then… maybe our models about stars are fundamentally wrong. But I doubt it; the maths to work out what the signature should be (given the composition) is pretty simple. Take a blackbody, put spectral lines as measured in the lab onto it, then redshift it.
