I am reading about rotating water in bucket - about Mach's principle. But, how general relativity explains this bucket.
1. Let us say, that bucket with water is the only object in universe. What GR says.
2. Let us say that one star in distance is in this universe. How rotating water "know" that it rotates and so curves it surface.
3. etc.
