Hi:
The topic was, " C is not constant "

I suppose we are entitled to know if that is offered as a fact or as a conjecture open to more discussion. One way to approach the issue is to explain why light travels at about 186,281 miles per second. If the beleivers could do that it would be a major step to solving the issue. We could then use that info to see if larger stars put out faster light and smaller stars less. Or we might find that size was not really important as some contend.

We measure light in the Earth's neighborhood at about 186,281 miles per second but no one seems to know why. I think I know why. I have published the reason and the math but I do not expect to find any converts.
