I’d like to believe that we’ve already found evidence of an expanding technological civilization only 1500 light years away, and civilization has barely changed at all: https://iopscience.iop.org/article/10.3847/1538-3881/ac3416 https://iopscience.iop.org/article/10.3847/1538-3881/ac3416 (note: not very serious, pretty unlikely, but fun to think about.)
- mrlonglong 4y agoIt's most likely to be dust getting in the way. Who knows?
- wolfram74 4y agoMaybe it's a dyson sphere, maybe not. Any stellar engineering project will /probably/ be ambiguous enough that discovery of other industrial life will be a slow gradual process like most scientific discoveries. With fractionally more of the populace accepting the premise with each piece of accumulated evidence.
