Spacetime meaning
The four-dimensional continuum of the three spatial dimensions plus time. | An n-dimensional continuum consisting of dimensions of both space and time. Normally spacetime is considered as having 4 dimensions (x, y, z, t), but higher-dimensional spacetimes are often encountered in theoretical physics, e.g. the 5-dimensional spacetime of Kaluza-Klein theory or the 11 dimensions of spacetime in M-theory. | A specific region of the universe with mathematically different properties than the surrounding spacetime. Synonymous with "metric" within the context of general relativity.

Spacetime background dependence main A fundamental lesson of general relativity is that there is no fixed spacetime background, as found in Newtonian mechanics and special relativity ; the spacetime geometry is dynamic.
Certain types of world lines are called geodesics of the spacetime – straight lines in the case of Minkowski space and their closest equivalent in the curved spacetime of general relativity.
Classification of the homogeneous Lorentz group From the invariance of the spacetime interval it follows immediately : and this matrix equation contains the general conditions on the Lorentz transformation to ensure invariance of the spacetime interval.
Einstein proposed that spacetime is curved by matter, and that free-falling objects are moving along locally straight paths in curved spacetime.
Here is the covector derivative in any spacetime and reduces to in flat spacetime.
Instead of viewing gravity as a force field acting in spacetime, Einstein suggested that it modifies the geometric structure of spacetime itself.
More generally the spacetime interval in flat space can be written as with metric tensor g independent of spacetime position.
Spin networks do not represent quantum states of a field in spacetime: they represent directly quantum states of spacetime.
These theories rely on general relativity to describe a curved background spacetime, and define a generalized quantum field theory to describe the behavior of quantum matter within that spacetime.
The term spacetime has taken on a generalized meaning beyond treating spacetime events with the normal 3+1 dimensions.
The vertical black line is the Earth's path through spacetime and the other two sides of the triangle show the ship's path through spacetime (as in the Minkowski diagram above).
White lines do not represent the curvature of space but instead represent the coordinate system imposed on the curved spacetime, which would be rectilinear in a flat spacetime.
LIGO is an international network of laboratories that detect the ripples in spacetime produced by the movement of large celestial objects like stars and planets.
They say the acceleration is the result of a previously unknown interaction between black holes and spacetime.
It’s only when you go far away from everything that the densities of matter drop enough that the entropic nature of spacetime, and hence of gravity, starts to become apparent.
In addition to that, the fabric of spacetime itself does not remain static over time.
It maps bumps and wiggles in spacetime—the cosmic microwave background, or CMB—and reflects conditions in the early universe as set by Hubble's constant.
Large events, such as collisions between massive objects, can create ripples in spacetime, like those produced as a rock is tossed in a pond.
In lieu of that, you average instead over all possible spacetime geometries.
A group physics project became a lot more interesting this past Friday when a lack of initiative was so great that it caused a rift in spacetime.
