Reducing Physical Reality to Space and Time Alone: The ST Unit Framework

This upload presents the ST Unit Framework: A systematic re-expression of all physical quantities using only two base dimensions: space (S, length) and time (T). Starting from the observation that energy can be defined as T/S, mass becomes T³/S³ and charge becomes T²/S². With these substitutions, every SI quantity and constant collapses into pure powers of S and T. No new physics is introduced; the framework simply removes the extra base units and allows direct comparison between mechanical, electrical, and magnetic quantities that are usually kept separate. Several striking relationships become immediately visible in the resulting table: Electrical quantities are fundamentally time-dominant (T-heavy), while magnetic quantities are distance-dominant (S-heavy). The first and second radiation constants reduce to pure S and pure T, respectively. The reciprocal of magnetic permeability μ₀ (S²/T) is exactly the dimension of both force F and electric current I (T/S²). The reciprocal of Planck’s constant h (T²/S) is exactly acceleration a (S/T ²). Mass m and capacitance C both reduce to T³/S³. The Hubble constant H₀ and the electric field E are both pure 1/T. The Lorentz number collapses to S⁴/T⁴ — velocity to the fourth power. These patterns emerge purely from the dimensional reduction and highlight connections that are hidden in the conventional SI system.V1.1:Updated to Revtex 4-2 format.Added abstract.Fixed error in Columb Constant units in figure 1 and table 1.Removed incorrect Thermal Condictivity row from table 1.
