In physics, spacetime is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects such as how different observers perceive where and when events occur.
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.

ceptions about space-time is called for, to yield the field-laws of the matter-tensor in a natural fashion. This was the second reason for looking upon the theory of 1915 as referring to pure gravitation only. The geometric structure of the space-time model envisaged in the 1915 theory is embodied in the following two principles:
1. Feb. 2022 · February 1, 2022. 15 min read. What Is Spacetime Really Made Of? Spacetime may emerge from a more fundamental reality. Figuring out how could unlock the most urgent goal in physics—a quantum...
13. Nov. 2020 · Summary. 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. Investigations into the epistemic and ...

9. Mai 2018 · In this model, the degree of entanglement defines a notion of spatial distance. In physics and, more generally, in the natural sciences, space and time are the foundation of all theories. Yet we ...
31. März 2024 · Space-time, in physical science, single concept that recognizes the union of space and time, first proposed by the mathematician Hermann Minkowski in 1908 as a way to reformulate Albert Einstein’s special theory of relativity (1905). Learn more about space-time in this article.
