In experiment 1, the geometrical state of the field in which the light and the shadow evolve at the exit of vertical slit is only a transient state : 2×2D horizontal. Using a horizontal slit positioned consecutive to this vertical slit, the geometrical state of the field is transformed : 2×2D orthogonal. The system opens and the accesses can be viewed.

The system is defined experimentally as timeless. It is a geometry in itself. 2 places of space are brought together via a hole in which time is canceled. Although this geometry is based on right angles and the entry angle in E = arctan (1/2), the hole is circular in shape.

From a physical point of view, because of the characteristics of this geometry, it is the speed parameter that makes it possible to include reality in the system.
