2. Dez. 2015 · A hundred years ago today Albert Einstein published his General Theory of Relativity—a brilliant, elegant theory that has survived a century, and provides the only successful way we have of describing spacetime. There are plenty of theoretical indications, though, that General Relativity isn’t the end of the story of spacetime.

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.
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 ...
