Bro you'd need at least K3 to do that and the IR signature would be all over the place. Why would you paint a target like that SMH

[–] WaxedWookie@lemmy.world 2 points 2 years ago

A relatively low-tier K2 civilisation could almost certainly do it, but why the fluctuation in the IR signature rather than a more steady "shadow" indicative of a more consistent harvesting/drain?
