This is how I understand the "elevator". It is_infinitely_ small. It encloses a single point in space rather than region of space so it is impossible to detect tidal variations from inside the elevator. If the elevator is allowed to have finite dimensions so that tidal variations are detectable the

A related question regarding frequency shifts of photons is associated with the apparent changes associated with the expansion of space and the emission of photons from distant objects receding at a great velocity from a receptor/monitor on earth. The explanation I have heard is that it’s li

According to the shell theorem the gravitational force on a test mass inside a hollow sphere is every where zero. This paper argues that this situation is not equivalent from the standpoint of General Relativity to the situation where gravity falls to zero far outside the sphere. They conclude tha
