# WHAT IS WRONG WITH SCHWARZSCHILD'S COORDINATES?

@inproceedings{Czerniawski2002WHATIW, title={WHAT IS WRONG WITH SCHWARZSCHILD'S COORDINATES?}, author={Jan Czerniawski}, year={2002} }

A strict derivation of the Schwarzschild metric, based solely on Newton’s law of free fall and the equivalence principle, is presented. In the light of it, regarding Schwarzschild’s coordinates as representing the point of view of a distant observer resting relative to the source of a centrally symmetric gravitational field, proves illegitimate. Such point of view is better .

The history, aims, results, and future prospects for the various analogue models of gravity are discussed, including a particularly simple example of an analogue model and the rich history and complex tapestry of models discussed in the literature.

The river model of black holes

We present a lesser known way to conceptualize stationary black holes, which we call the river model. In this model, space flows like a river through a flat background, while objects move through the…
