In physics, Stoney scale units are units of measurement named after the Irish physicist George Johnstone Stoney, who first proposed them in 1881. They are an example of natural units, i.e. units of measurement designed so that certain fundamental physical constants are normalized to unity. The constants that Stoney units normalize are the following.
- Elementary charge, e;
- Speed of light in a vacuum, c;
- Dielectric vacuum constant, ε;
- Gravitational vacuum "dielectric constant", εG;
- Planck constant, h;
- Boltzmann's constant, kB (or simply k).
Each of these constants can be associated with at least one fundamental physical theory: c with special relativity, εG with general relativity and Newtonian gravity, e and εE with electrostatics, and k with statistical mechanics and thermodynamics. Stoney units have profound significance for theoretical physics since they simplify several recurring algebraic expressions of physical law by nondimensionalization. They are particularly relevant in research on unified theories such as quantum gravity.
History
[edit]Contemporary physics has settled on the Planck scale as the most suitable scale for the unified theory. The Planck scale was however anticipated by George Stoney.[1] James G. O’Hara[2] pointed out in 1974 that Stoney’s derived estimate of the unit of charge, 10−20 Ampere (later called the Coulomb), was 1⁄16 of the correct value of the charge of the electron. Stoney’s use of the quantity 1018 for the number of molecules presented in one cubic millimetre of gas at standard temperature and pressure. Using Avogadro’s number 6.0238×1023, and the volume of a gram-molecule (at s.t.p.) of 22.4146×106 mm3, we derive, instead of 1018, the estimate 2.687×1016. So, the Stoney charge differs from the modern value for the charge of the electron about 1% (if he took the true number of molecules).
Stoney scale and Planck scale are intermediate between microscopic and cosmic processes and it was soon realized that either could be the right scale for a unified theory. The only notable attempt to construct such a theory from the Stoney scale was that of H. Weyl, who associated a gravitational unit of charge with the Stoney length[3][4]. [5] and who appears to have inspired Dirac’s fascination with LNH[6]. However, Weyl’s dogmatic adherence to the principle of locality reduced his theory to a mathematical construct with some non-physical implications. The Stoney scale thereafter fell into such neglect that it should to be re-discovered by M. Castans and J. Belinchon[7], and by Ross McPherson[8]
For a long time the Stoney scale was in the shadow of the Planck scale (something like a "deviation" of it). However, after intensive investigation of gravity by using the Maxwell-like gravitational equations during last decades, became clear that Stoney scale is independent scale of matter. Furthermore, it is the base of the contemporary electrodynamics and gravidynamics (classical and quantum). Due to McDonald[9] first who used Maxwell equations to describe gravity was Oliver Heaviside[10] The point is that in the weak gravitational field the standard theory of gravity could be written in the form of Maxwell equations[11] It is evident that in 19th century there was no SI units, and therefore the first mention of the gravitational constants possibly due to Forward (1961)[12]
In the 1980s Maxwell-like equations were considered in the Wald book of general relativity[13] In the 1990s Kraus[14] first introduced the gravitational characteristic impedance of free space, which was detailed later by Kiefer[15], and now Raymond Y. Chiao[16] [17] [18] [19] [20] who is developing the ways of experimental determination of the gravitational waves.

Considering that all Stoney and Planck units are derivatives from the ‘’vacuum units’’, therefore the last are more fundamental that units of any scale.
The above fundamental constants define naturally the following relationship between mass and electric charge:
and these values are the base units of the Stoney scale.

Secondary Stoney scale units
[edit]All systems of measurement feature base units: in the International System of Units (SI), for example, the base unit of length is the meter. In the system of Stoney units, the Stoney base unit of length is known simply as the ‘’Stoney length’’, the base unit of time is the ‘’Stoney time’’, and so on. These units are derived from the presented above primary Stoney units, which are arranged in Table 1 so as to cancel out the unwanted dimensions, leaving only the dimension appropriate to each unit. (Like all systems of natural units, Stoney units are an instance of dimensional analysis.)
Used keys in the tables below: L = length, T = time, M = mass, Q = electric charge, Θ = temperature. The values given without uncertainties are exact due to the definitions of the metre and the ampere.

Derived Stoney scale units
[edit]In any system of measurement, units for many physical quantities can be derived from base units. Table 2 offers a sample of derived Stoney units, some of which in fact are seldom used. As with the base units, their use is mostly confined to theoretical physics because most of them are too large or too small for empirical or practical use and there are large uncertainties in their values

Planck scale units
[edit]For the sake of completeness in the Table 3 presented the main Planck units in the form consistent with above tables for Stoney scale.

As could be seen from the table, the main difference between Stoney and Planck units - the fine structure constants. For example, the wave vacuum impedance in the Planck scale will be:
This is due to the difference in fine structure constants. Actually, the relationship between "static" and "dynamic" forces in the Planck scale is:
but in the Stoney scale it will be:

Note that, the Natural scale has different values for the fine structure constants (as the Planck scale does). However, this difference is so high, that this scale now is the base for the LNH and different numerology approaches [8]. Actually, the relationship between Stoney and Natural fine structure constants yields the s.c. Dirack number:
Weak interaction Natural scale units
[edit]The weak scale of Natural units is based on the neutrino mass. As is known, neutrinos are generated during the annihilation process, which is going through intermediate positronium atom. The effective mass of the positronoum atom is:
where are electron and positron mass respectively. The energy scale for the positronium atom is:
where is the length scale for positronium, and is the upper value for the neutrino mass, and is the weak interaction force constant (or weak fine structure constant).

Weak Planck scale units
[edit]The primordial level of matter has two standard scales: Planck (defines the Planck mass) and Stoney (defines the Stoney mass). However, it has the third primordial scale that could be named as the weak interaction scale, which has the following force constant:
that is the same as in the weak natural scale.
The weak primordial mass will be:
- kg,
where is the Planck mass.
The weak primordial wavelength is:
- m
The weak primordial time is:
- s

[edit]The standard definition of the work function in the strength field is:
So, the complex weak displacement work in the weak natural force will be:
where

Considering the Universe bubble as the minimal energy scale:
where is the Universe wavelength, and equating the above energies, we derive the following fundamental relationship:
from which the Universe length parameter could be derived:
- m
which value is consistent with the 15 billion years. The Universe time constant ("age") could be derived from the following relationship:
where s, and are the Planck time and wavelength respectively.
