Oh, it needs it's own thread. However, the only problem will be the lack of participation over there. There are simply not enough kooks to keep OW, UD, Brainstorms, and youngcosmos amusing. The most notable thing about most of those sites is the lack of discussion, in comparison to something as inane as "pokemon forum" which gets almost 50,000 hits in google, for example. And I imagine most of them get more traffic the all the ID forums combined!

Well, SN1987A is 169,000 light years away.
This distance is independent of the speed of light decaying or not! A counter-intuitive result, but one you can check for yourself.
SN1987A formed a ring, and light from the supernova bounced off the ring and arrived at earth 400 days later than the supernova. To keep the analysis simple, make a right triangle (the ring is not perpendicular but tilted in reality).
The angle is 1.66 arc seconds or 1.66 / 3600 degrees. The sine is the diameter of the ring. The cosine is the distance to the supernova. The hypotenuse is the light bouncing off the ring. The path length difference is 400 days, since the hypotenuse and cosine are very close to the same length. Now assume that the speed of light was ten times faster for one year. Both rays of light travel the same distance (10 light years), with the remaining distance to be travelled still 400 light days different, and the light arrives 400 days apart.
