Description
We consider spacetime foliation, at every given moment according to canonical observers, each with its speed at that moment. Consider a black hole spacetime as a spacetime with horizon. The Universe in that sense look like a sequence of frozen moments like a cartoon movie. The Rindler observer would analyze the ADM formalism as if the shift function Ni equal zero. Therefore, the normal vector 𝑛 to the spatial slice is proportional to the time basis 𝜕𝑡 of Rindler frame field with proportionality factor that is equal to the lapse function. This is the only way to make special relativity preferred frames match with general relativity Rindler frame.
