Sorry, I'm not Amara Graps, but I hope I will suffice. That sounds like an
interesting theory, but I have a few questions. Is there even enough
artificial space dust for anyone to detect? I know that planets are
determined to exist in a solar system, not because we can view them
directly, but because they exert a detectable gravitational force on their
sun. If we cannot even see a planet directly, how would we detect space
dust? I am not by any means an expert on the subject, so if I am incorrect
in my assumptions here, please correct me.

Did anyone else have trouble accessing the link provided by Sean Williams? I
encountered an error.

On a side note, Googlewhacking is surprisingly fun.
