Abstract:
Insufficiency complaints at most are ranging about singularities or the arbitrariness of input assumptions, which might be controlled but not satisfactorily founded:
Six main problems of field theories are traced back to their roots:
- The infinitesimal calculus is promoting continuous models - ignoring error bars confining basic physics to finite, atomistic models.
- The variation principle, once good for point mechanics, introduced hosts of arbitrary parameters instead of relying on consistent correlations by Clebsch-Gordon coefficients.
- And cosmologists, tightly sticking to diff. geometry, are strictly ignoring the implications of group theory.
Six main problems of field theories are traced back to their roots:
- Infrared singularities.
- Inconsistencies resulting from Kronecker deltas.
- Ultraviolet singularities.
- Arbitrary coupling constants.
- The variation principle, basic to the "standard model".
- Mathematical limits (implying infinities).
