I was reading this example from Wikipedia: You are standing in a field looking at the stars. Your arms are resting freely at your side, and you see that the distant stars are not moving. Now start spinning. The stars are whirling around you and your arms are pulled away from your body. Why should your arms be pulled away when the stars are whirling? Why should they be dangling freely when the stars don't move? I am experiencing some difficulty understanding why Mach's principle says that, somehow, the stars moving and your hand being pulled is not a coincidence. To me, the answer to the above question is that whirling stars imply you are spinning, and vice versa. How can there be an intimate relation between something far away out there and local events?
