I don't understand what you're saying. It was your point that we don't know what might be obstructing starlight on its way to us. Or are you saying that there could be something making starlight go faster than 186,000 miles per second?

Oh, gee, how do we focus laser light and make light powerful enough to destroy things. Even your own crowd has argued that the speed of light has not remained constant. Faster or slower is accomplishable through natural processes. Scientists have argued with regard to light speed only that which they could observe. But they have observed it slowing over time. This tells us a couple of important things that should be obvious at this point.

Faster or slower is accomplishable through natural processes.

Name one natural process that makes light travel faster.

(BTW, light doesn't really ever travel slower. What happens is that the electric field polarizes the medium, but that polarization takes time, becasue electrons have to move, so the electrical field change propagates slower than c.)
