Then again, there might be a new type of energy that can be drawn from the time dimension,
In which case, we have two types of electrons, both almost massless because of missing or oscillating \(t_g\). An oscillating field can be subjected to a similar field and displays a bias that is observed as a small mass/inertia. Without \(t_g\), massless, would mean a wave; a pure wave.
This might destroy wave-particle duality. Wave and particles are separate entity with the similar field properties.
And there's a lot more types of particles.
If \(t_c\) is also oscillating then there are two wave/particle superimposed in a orthogonal direction. And this beast,
\(\cfrac{\partial^2\psi}{\partial\,t^2_c}=ic\cfrac{\partial^2\psi}{\partial\,x\partial\,t_c}\)
is sleeping with,
\(i\cfrac{\partial^2\psi}{\partial\,t^2_m}=-c\cfrac{\partial^2\psi}{\partial\,x\partial\,t_m}\)
in an orthogonal manner, \(i*i=-1\).
Four types of energy (Platonic Solids) can be drawn from the time dimension, (a believe, not science) in different combinations of a wave creates different particles. Particle may superimpose orthogonally and manifest as different distinctive particles with different (superimposed) properties.
Those with \(t_g\), gravitational energy are particles with mass, those with oscillating \(t_g\) display small mass under gravitational field. The rest (absolutely no \(t_g\)) are photons for the time being.
Good night.
