The Relative Symmetry Principle A new general physical principle can be enunciated after the considerations on symmetry which have led us to a purely geometric justification of momentum.
We will call this principle: “ Relative Symmetry Principle ”
It says that every body, being a source of elementary waves, behaves so as to mantain symmetrical every wave “variation” all around itself.
For the Relative Symmetry Principle, the variation of the wave energy is defined by the formula:
23)
This formula describes the variation of the wave energy that intervenes in the wave field of any mass, in the same way as the variation of the wave energy taking place in the symmetrical point, opposite to the barycenter.
As indicated afterwards, this new principle will replace the Energy Conservation Principle and will be more descriptive and general than the first one.
Thanks to it, we will be able to justify the entity and the behaviour of the four known interactions, and to foresee, indirectly, the existence of a fifth repulsive interaction.
(The prediction and the behaviours of a fifth repulsive interaction have already been described in 1984 in the book: The Unified Field, already quoted above).
We can know the explicative ability of this principle by deriving from the isotropy properties of the space-time a relativistic description of momentum, through which we naturally reach the relativistic variation of mass.
The unified application of this principle to all the phenomena of interaction between radiation and matter, and of motion of bodies sets aside the observability conditions, and also acts where we are not able to directly observe it in its casual developments.
