I think he meant that, if a star has a Dyson sphere around it, you
can't see the star in visible light (== higher frequency than
infrared). In fact, you can't see the star at all. You can only see
the infrared light that the Dyson sphere emits.


As an aside about the "allowing external posters" thread: I'm not subscribed to this list, because I can't afford the time to recieve 50 messages a day. However, I occasionally visit the web site and respond to posts that way. If you only allowed posts by approved members of the list, I wouldn't be able to do that.

Perhaps there should be a list of "allowed posters", separate from (and presumably a superset of) the list of recipients.
