Should still be visible if a super civilization gets to a point where it needs to harness the power equivalent of an entire star (or even far sooner) then even if they don’t do it via a dyson sphere the waste heat alone should still be detectable.

- ben_w 3y agoIf they can summon enough power to not need or want a galaxy worth of Dyson swarms, then either (1) they are powerful enough to not need or care to hide, or (2) they're hiding because there is something out there that makes a galaxy's worth of Nicoll-Dyson beams seem trivial and insignificant as a weapon. For reference, a K3 civilisation worth of Nicoll-Dyson beams can gravitationally unbind[0] 10^9 Earthlike planets in just under 26 days. [0] https://youtu.be/7g77WN6obk4 https://youtu.be/7g77WN6obk4
