space time continuum?
what is the space time continuum ?

According to Einstein space and time are inter-related.
Both space and time were thought to have been created with the big bang about 13 billion years ago.
The big bang was an expansion of energy into the newly created space time continuum.
Initially the energy was infinitely hot, but it cooled on expansion and when the temperature reached a low enough level, matter was formed from the energy.
According to Einstein, matter and energy are interchangeable.
And in the space time continuum, energy and matter affect each other. It is observed that a massive body like a star, or a galaxy, can bend light (a form of energy) when the light passes nearby.
At the present time the real nature of the space time continuum is not fully understood.
It is currently the subject of research. String Theory and M Theory are two attempts to explain it further. But as yet a single coherent theory eludes us (the scientific community).

According to the research being done by Dunn the space-time continuum is a non-dimensional causal element (quantum causality) where aliased relationships of constants form systems of relativity with results similar to snow-flakes.
Describing the causality systems of relativity lends itself to String Theory.
Quantum Entangled Singularities (dunn) is the foundation of relativity from quantum causality.
The model intends to use set theory to separately treat space from time to manipulate space-time.

In physics, spacetime (or space–time; or space/time) is any mathematical model that combines space and time into a single continuum. Spacetime is usually interpreted with space being three-dimensional and time playing the role of a fourth dimension that is of a different sort from the spatial dimensions. According to certain Euclidean space perceptions, the universe has three dimensions of space and one dimension of time. By combining space and time into a single manifold, physicists have significantly simplified a large number of physical theories, as well as described in a more uniform way the workings of the universe at both the supergalactic and subatomic levels.
In classical mechanics, the use of Euclidean space instead of spacetime is appropriate, as time is treated as universal and constant, being independent of the state of motion of an observer. In relativistic contexts, however, time cannot be separated from the three dimensions of space, because the observed rate at which time passes for an object depends on the object's velocity relative to the observer and also on the strength of intense gravitational fields, which can slow the passage of time.

 Concept with dimensions
The concept of spacetime combines space and time to a single abstract "space", for which a unified coordinate system is chosen. Typically three spatial dimensions (length, width, height), and one temporal dimension (time) are required. Dimensions are independent components of a coordinate grid needed to locate a point in a certain defined "space". For example, on the globe the latitude and longitude are two independent coordinates which together uniquely determine a location. In spacetime, a coordinate grid that spans the 3+1 dimensions locates events (rather than just points in space), i.e. time is added as another dimension to the coordinate grid. This way the coordinates specify where and when events occur. However, the unified nature of spacetime and the freedom of coordinate choice it allows imply that to express the temporal coordinate in one coordinate system requires both temporal and spatial coordinates in another coordinate system. Unlike in normal spatial coordinates, there are still restrictions for how measurements can be made spatially and temporally (see Spacetime intervals). These restrictions correspond roughly to a particular mathematical model which differs from Euclidean space in its manifest symmetry.
Until the beginning of the 20th century, time was believed to be independent of motion, progressing at a fixed rate in all reference frames; however, later experiments revealed that time slowed down at higher speeds (with such slowing called "time dilation" explained in the theory of "special relativity" ). Many experiments have confirmed time dilation, such as atomic clocks onboard a Space Shuttle running faster than synchronized Earth-bound inertial clocks and the relativistic decay of muons from cosmic ray showers. The duration of time can therefore vary for various events and various reference frames. When dimensions are understood as mere components of the grid system, rather than physical attributes of space, it is easier to understand the alternate dimensional views as being simply the result of coordinate transformations.
