Mikroskopische Anatomie der Zähnet physics should be independent of the choice of coordinate system. This is already present in Newtonian dynamics, where that the inertial mass of a particle is equal to its gravitational mass. Consider a thought experiment due to Einstein where we have an observer in a box. The observer should not

https://doi.org/10.1007/978-3-662-40967-1is compressed into a small region of space-time. It is characterized by a curvature singularity at the origin which is ‘screened’ to outside observers by a coordinate singularity at finite radial distance. This coordinate singularity is known as the ., which will be seen to exhibit deep connections

Today we will consider a new coordinate system which will allow us to double the space-time and find copies of regions . and ..

https://doi.org/10.1007/978-3-642-91095-1act that if we throw an object with some entropy into a black hole, the entropy of the total system may not decrease, hence the entropy of a black hole must grow when we throw an object into it. Such thought experiments can be used to derive the laws of black hole mechanics, which turn out to be pro
