Our Sun is a Star

What you are trying to measure here is a quantity of light, not the speed.

It simply appears that the light from the distant star takes longer to reach us, the observers. When you say 'as has been measured' this is what it means. You are not thinking in terms of SpaceTime .. only of space. Light that takes 'longer' to reach us appears to have come from a different location in the past!

It would be observationally impossible to measure a change of direction of a sphere of light, when at the same time surrounded by it.
Even though it appears to us as a beam of light being attracted by the sun during a solar eclipse, it’s really is not, is it?
The stuff we mess with! |
MJA ... This doesn't really make a lot of sense ... especially the solar eclipse bit ? If you give yourself a basic understanding of relativity, independent of whether you choose to accept it or not, we would be able to converse a lot easier. I have a really good link for relativity, but not on this computer ... If you think you are interested reply and I will look it up and post it.
Hope I helped and didn't add to the confusion.
