STRUCTURE OF SPACE-TIME

My interpretation of space-time is that each object or body (event for somebody) is a structure of space-time. The magnitude of the space-time depends on the mass and density of the object. These objects can be: a particle, a molecule, a table, a planet or a galaxy. The space-time consists of four dimensions.
The gravity of the stars is transmitted through photons or dark energy, distorting the space-time around them.

In a formula:

stu = m + (gΔb, x) p

A space-time unit or "object" is equal to the mass more the gradual increment of an uniform rhythm becoming since a moment x in a point of space p.

Albert Einstein was right.

STRUCTURE OF SPACE-TIME

The formula stu = m + (gΔb, x) p relates the mass, the time law (tu = g∆b, x) and space. This is not an arithmetic sum but a combination of factors: mass, flowing time and space. Each object warps space-time around them, but this effect depends on the mass of the body and in the reality they are: macrocosm and microcosm. The effect of nuclear forces, weak and strong, is to an atom level. 

Dark energy fills all space and is composed by photons. It is called dark because doesn't emit radiation. The term "dark energy" was coined by Michael Turner in 1998.
