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.- The World in A String Duet

Today the most popular candidate theory of quantum gravity among physicists is string theory. According to this idea, the eponymous strings are the fundamental constituents of matter and energy, giving rise to the myriad fundamental subatomic particles seen at particle accelerators around the world. They are even responsible for gravity—a hypotheti...

If the string theorists are correct, then space is built from quantum entanglement, and time might be as well. But what would that really mean? How can space be “made of” entanglement between objects unless those objects are themselves somewhere? How can those objects become entangled unless they experience time and change? And what kind of existen...

**String theory**is not the only idea that suggests spacetime is emergent. String theory has “failed to live up to [its] promise as a way to unite gravity and quantum mechanics,” says Abhay Ashtekar, a physicist at Pennsylvania State University. “The power of string theory now is in providing an extremely rich set of tools, which has been used widely ...Modern physics is a victim of its own success. Because quantum physics and general relativity are both so phenomenally accurate, quantum gravity is needed only to describe extreme situations, when enormous masses are stuffed into unfathomably tiny spaces. Those conditions exist in only a few places in nature, such as the center of a black hole—and,...

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.14.

**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).

**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.10.

**space-time structure**by Professor Erwin Schrödinger is now available in the Cambridge Science Classics series. First published in 1950, and reprinted in 1954 and 1960, this lucid and profound exposition of Einstein's 1915 theory of gravitation still provides valuable reading for ...
