The geometric structure of the space-time model envisaged in the 1915 theory is embodied in the following two principles: (i) equivalence of all four-dimensional systems of coordinates
13 de nov. de 2020 · This exploration of the global structure of spacetime within the context of general relativity examines the causal and singular structures of spacetime, revealing some of the curious possibilities that are compatible with the theory, such as 'time travel' and 'holes' of various types.

1 de fev. de 2022 · In loop quantum gravity, space and time are not smooth and continuous the way they are in general relativity. Instead they are made of discrete components—what Ashtekar calls “chunks or atoms...
Space-Time Structure: Einstein and Beyond. Thanks to Einstein's relativity theories, our notions of space and time underwent profound revisions about a 100 years ago.
3 de dez. de 2009 · Summary. In Einstein's theory of gravitation matter and its dynamical interaction are based on the notion of an intrinsic geometric structure of the space-time continuum.
The Large Scale Structure of Space–Time is a 1973 treatise on the theoretical physics of spacetime by the physicist Stephen Hawking and the mathematician George Ellis. It is intended for specialists in general relativity rather than newcomers.
Spacetime topology is the topological structure of spacetime, a topic studied primarily in general relativity. This physical theory models gravitation as the curvature of a four dimensional Lorentzian manifold (a spacetime) and the concepts of topology thus become important in analysing local as well as global aspects of spacetime.
