CURVATURA SPAZIO-TEMPO (Space-time curvature)

The presence of mass placed in space bends light, this is because mass "bends" space-time, a 4-dimensional concept.

This expression is intended to represent this concept in three dimensions, making the space of the canvas two-dimensional and representing the quantity of mass with the third dimension of the sphere and time with the third dimension of the canvas.

In this way a physical concept is represented, and the parallelism in this work goes with human thought, which similarly to light is curved by events by people and everything that can happen to a human being in the course of his or her life.

Thought therefore is not rectilinear, but is influenced by the whole cosmos around it.
