[ExI] Islands of trans-humanity

[Kelly Anderson]

Detailed spectral analysis of the star's light could reveal
differences between a Dyson cloud and dust. A Dyson cloud would likely
show some signs of energy conversion, such as excess waste heat, which
might manifest as an infrared signature. Dust clouds would not produce
such heat signatures. Has such an analysis been done?? I would guess
so, but I don't know the answer.
