Does it say Mach Principle is incorrect? That is good, as a non physicist I could never wrap my head around the distant stars influencing anything.

- akvadrako 9y agoThe distant stars are important because they make space flat. Remember that general relativity says mass bends space, or more accurately is the same thing as space. So if all the mass was nearby, space would bend inward around the current point and it would fold in on itself - the universe would be like the inside of a sphere. Because the mass is distributed evenly at the largest scales, it instead continues flatly in all directions.
- posterboy 9y ago> the universe would be like the inside of a sphere. The surface of which is "flat"? The interior surface, if that's the right word. Like living on the Event Horizon of a black hole. So we don't and hardly can know what's outside or inside or on the outside or inside.
