Ansible Interview

This is the message as the crawl holds it, before anything here touched it. What the conversation shows has been through ingest: transfer encodings decoded, attachments dropped, quote markers repaired, and the archiver’s ? resolved into quotation marks and dashes. Those repairs are judgements and some of them are wrong, which is what this page is for. Email addresses are obscured here as they are everywhere else on the site, so it is before our repairs rather than byte for byte.

Of course, those are distinct multiple light sources, right? Here, we'd have a smooth curve of an infinite number of light sources. But the light sources would be close---closer than the SUN---so perhaps there would in fact be a significant shadow effect. 

I don't pretend to know, I just think we know enough to bring the observation into the realm of the artistically possible. Which still doesn't explain Wolfe's flat rejection of it.

I forgot the other possibility that you alluded to. If the LS is in fact not a narrow cylinder but 2 narrow, thin panels set back to back, then there would be some lessening of light output near dawn and dusk, at the very edges. This would lead to some dimming, but not to more shadows. Just stronger ones, perhaps---the overwhelming effect of permanent noon would be reduced. And dawn would still seem to snap up like a windowshade.

I suppose it would be risky to make your sun a single huge fluorescent tube. Where would you get a replacement if it broke? ;)

I'm sitting under tubular flourescent bulbs (complete with shade unit) all day long, right now in fact.  I guarantee there are shadows.  they're sort of diffuse, but they are definitely shadows.
