Feynman rules of all QFT must
be rewritten with extended
harmonic oscillating points in the 2D-plane orthogonal to the
observed direction of motion (SR worldline).
The spacelike constant vector explains the spin (helicity) and
the timelike constant explains why the energy of any particle
is proportional with a detected frequency. All elementary
particles aren't able to reach one another at zero-distance, but
the closest distance in any calculation will be equal to the
average extendedness of the harmonic oscillating
of the order of the Planck length.
This removes all divergences in all QFT without the need for a
but instead the extended spin2
be included in the mathematical model to explain mass correctly!
is based on an elementary
spinless boson (with a
very high mass > 125 GeV/c2), but this
mechanism does NOT
comply to Einstein's CAP!
To me, the extended elementary particles perturbation QFT
with included the gravitational field is the mathematically most
exact description of our 4D-universe, even though it's a
bation theory with uncountable many elementary
