Kaluza from particles to galaxies — •Thomas Schindelbeck — IRAEPH Mainz

Reducing Kaluzas original ansatz to inserting the electromagnetic potentials into a 5D metric and dropping all other assumptions provides a coherent, consistent and quantitative description of phenomena related to particles and particle interaction, e.g.

1) with boundary condition spin 1/2 a convergent series of quantized particle energies, with limits given by the energy values of the electron and the Higgs vacuum expectation value,

2) electromagnetic and gravitational terms will be linked by a series expansion,

3) minor terms in the metric will give a term in the order of magnitude of vacuum density / cosmological constant,

4) the interpretation as a 5D deSitter space gives an expression for the Baryonic Tully Fisher Relation of galactic rotation curves that can be traced back to the particle level.

The model can be expressed ab initio, i.e. without free parameters.
