- Spacetime - Wikipedia
In physics, spacetime, also called the space-time continuum, is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum
- Space-time | Definition Facts | Britannica
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) (Read Einstein’s 1926 Britannica essay on space-time )
- What Is Spacetime? The Four-Dimensional Fabric of Reality
Albert Einstein, through his groundbreaking work on relativity, dramatically changed our understanding of space and time The key insight he brought was that space and time are not separate entities but woven together into a single four-dimensional fabric called spacetime
- Einsteins right again! Scientists catch a feasting black hole dragging . . .
This swirling of spacetime first emerged from Albert Einstein 's 1915 theory of general relativity, which predicted that objects with mass "warp" the fabric of space and time (united as a single

Specifically, spacetime might emerge from the materials we usually think of as living in the universe—matter and energy itself
- Time might not exist – and were starting to understand why
Here, things get very murky Some approaches still start from something like traditional coordinate time, but then add time again as part of a spacetime with more dimensions than the four we’re used to In other approaches, time emerges from more fundamental concepts about the Universe

Space-time is the conceptual model that best explains how the universe works (Image credit: Shutterstock) The fabric of space-time is a conceptual model combining the three dimensions of
- GP-B — Einsteins Spacetime
Gravity feels strongest where spacetime is most curved, and it vanishes where spacetime is flat This is the core of Einstein's theory of general relativity, which is often summed up in words as follows: "matter tells spacetime how to curve, and curved spacetime tells matter how to move"
