A test Idea is :

A display of an active cyclic oscillating subton idea* expressed in a Minkowski helicity diagram using the basis set of gamma unit 1-vectors of the Geometric Space-Time Algebra⁴ introduced by David Hestenes back in 1966, miming the space-time form structure of the Dirac matrices.

It is essential to remark, that the concept orthogonality and the concept perpendicular display has no similarity in a Minkowski display. In that two qualitative different directions: space and time that is orthogonal can be displayed parallel in a diagram.

* The subton idea is invented to describe the substantial structure of one photon quantum angular momentum oscillation, viewed  as one fundamental subject in the universal substance of Nature.
