Mach proposed a question, "Try to fix Newton's bucket and rotate the heaven of fixed stars and then prove the absence of centrifugal forces." The Lense-Thirring effect answered Mach's question, which meant that a rotating object would affect the space-time near it. If an object itself did not rotate, but the entire universe revolved around it in the opposite direction, the same effect cannot be produced. Is general relativity Machian? There were divergent opinions on this issue, and the two sides had roughly divided opinions. The existing research on Mach principle was mostly about the slow rotation of small mass objects, or considering the object was not a singularity and did not form an event horizon. Therefore, this article proposed the fact that: Kerr metric cannot be transformed into Schwarzschild metric by the conversion of the coordinate system. This fact overthrew Mach's thought, so the structure of space-time cannot be connected by simply transforming the rotation perspective.
