Good point and black holes are part of make me wonder about that given what it does to light and spacetime. All our measurements of the galaxy and universe is on a speed of light is in our gravity well and even though it drops off so quickly the suns is so huge we have to have quite a distance to get to where its inconsequential is way beyond earth. Knowing there it is the same 1000 au from the sun at high precision would be nice to know. It it showed any difference. Even slightly then it would be massive in our understanding of the universe.
not necessarily but at least far enough away that gravitational forces are way different. the sun contrls orbits for over 1000 au but neptune I think is the farthest circular orbit at 30 au. Our measurements at 1au have no practical gravitational variance at all but we assume light is uneffected by it.

Yeah, this is a teally intresting thought! The observation should be really somewhere outside of galaxies, or where there is almost no gravitation.
