IIRC, the entire solar-system is supposedly exempt from this expansion. IOW, the system best suited for observing this assumed effect is excluded by definition.
Just a little too convenient, don't you think?
Sorry, but that is incorrect. It's probably another myth pushed by Young-Earth Creationists.
The solar system is held together by gravity. If the expansion of space is stronger than gravitational attraction, then expansion wins. If gravity is stronger, then gravity wins.
Same thing with, say, two magnets. If they are a mile apart, there is no magnetic attraction. If they are half-an-inch apart, there is strong magnetic attraction (or repulsion, depending upon the polarity alignment.
The expansion of space takes place on a much greater scale then, say, the room in your house. Does this explain it well?
By the way, the notion of the expansion of space is something that is easily proved by observation. It's a fact that is not even in question.
