RE: [asa] Near Starlight Problem; Adam would never see all of Orion's belt?

Gordon,

Explain this further, if you could. The typical suggestion of the speed of
light being faster in the past is in contrast with the assumption that the
speed of light is constant. The distances I assume are measured by
independent means (parallax for near stars, increasingly complex
measurements for farther stars). Thus the time is t=c/d. The idea being
that if light moved faster in the past, then by our uniformity assumption,
the time would be less, and so on.

How do you say that the change in speed of light would result in
recalculation of distance? (I can imagine that some of the distance
measurement techniques might be based on the speed of electromagnetic waves;
i.e., light, but that wouldn't necessarily be true for parallax measurements
of close stars.) What does that have to do with the supernova?

If the speed of light really was faster when the supernova in the Magellanic
cloud occurred, then the recalculation of its distance would give a greater
distance since the light year at that time would have had a greater value.
Thus it would be an even greater problem for YEC.
