Bully Metric

| Bully Metric Development Page

Six base units are included in the Bully Metric system. Two variants of the apan are defined as spacetime units. Three variants of the nat are defined as transformation units. And the symbol "e" is used to represent elementary charge (the charge of a single electron).

The time apan (or timepan or apan) (symbol ta) is by definition exactly 30.55 picoseconds. The length apan (or lightpan, lengthpan, or apan) (symbol la) is by definition the distance light travels in vacuum in 30.55 picoseconds.

The infonat (natural unit of entropy) (symbol En) is defined such that for an ideal gas in a given macrostate, the entropy of the gas divided by the natural logarithm of the number of real microstates would be equivalent to one infonat.

The rapinat (natural unit of rapidity) (symbol Rn) is defined such that an object with a standard gravitational parameter equal to the speed of light in vacuum cubed multiplied by 30.55 picoseconds, will have a gravitational mass of one rapinat timepan.

The actionat (natural unit of action) (symbol An), and elementary charge (symbol e), are defined such that if a Josephson Junction were exposed to microwave radiation of frequency 2 / 30.55 picoseconds (≈ 65.4664484 gigahertz), then the junction would form equidistant Shapiro steps with separation of 2π actionats per timepan electron. Also,the quantum Hall effect will have resistance steps of multiples of 2π actionats per electron squared.

ta = 30.55 picoseconds (exact)

la = c × 30.55 picoseconds (exact)
   = 9.1586595919 millimeters (exact)

En = 1.380649 x 10-23 joule / kelvin (exact)

Rn = (c3 / G) (exact)
   ≈ 4.0370 × 1035 kilogram / second (approximate)

An = 4 / (2π × KJ2 × RJ)  (exact)
   = 1.05457182 × 10-34 joule second (approximate)

e = 2 / (KJ × RJ) (exact)
  = 1.60217663 × 10-19 coulombs (approximate)

The above definitions ensure normalization of the speed of light (c), Newton's gravitational constant (G), the Boltzmann constant (k_B), the reduced Planck constant (ħ), and the elementary charge (e):

$c=1.0\,{\frac {la}{ta}}$ (exact)

$G=1.0\,{\frac {{la}^{3}}{Rn\,ta^{3}}}$ (exact)

$k_{B}=1.0\,En$ (exact)

$\hbar =1.0\,An$ (exact)

$elementary\,charge=1.0\,e$ (exact)

Planck units and the Bully Metric

Table 1 below was taken from the Wikipedia Planck units article:

Table 1: Modern values for Planck's original choice of quantities

Name	Expression	Value (SI units)
Planck time	$t_{\text{P}}={\sqrt {\frac {\hbar G}{c^{5}}}}$	5.391247(60)×10−44 s
Planck length	$l_{\text{P}}={\sqrt {\frac {\hbar G}{c^{3}}}}$	1.616255(18)×10−35 m
Planck mass	$m_{\text{P}}={\sqrt {\frac {\hbar c}{G}}}$	2.176434(24)×10-8 kg
Planck temperature	$T_{\text{P}}={\sqrt {\frac {\hbar c^{5}}{Gk_{\text{B}}^{2}}}}$	1.416784(16)×1032 K

Planck to Bully conversion constant

Since c, G, k_B, and ħ are all normalized in the Bully system, this ensures that Bully units have a simple relationship with Planck's units. In fact, multiplying each value from Table 1 by 566.660, results in the corresponding Bully value multiplied by 10^-30:

566.660 × tP = 1.00001(11) × 10-30 ta
566.660 × lP = 1.00001(11) × 10-30 la
566.660 × mP = 1.00001(11) × 10-30 Rn ta

Table 2 below uses algebraic substitution to illustrate that there is a single multiplicative constant that converts between Planck and Bully values. When Planck energy is included in the table (see "Planck energy" row in Table 2), one finds that the Planck to Bully conversion factor for energy is the inverse of the mass, time, and length conversion factor.

Table 2: Planck's units relationship with Bully units

Name	Expression
Planck time	$t_{\text{P}}={\sqrt {\frac {\hbar G}{c^{5}}}}={\sqrt {\frac {An{\frac {la^{3}}{Rn\,ta^{3}}}}{\frac {la^{5}}{ta^{5}}}}}={\sqrt {\frac {An}{Rn\,la^{2}}}}\,ta$
Planck length	$l_{\text{P}}={\sqrt {\frac {\hbar G}{c^{3}}}}={\sqrt {\frac {An{\frac {la^{3}}{Rn\,ta^{3}}}}{\frac {la^{3}}{ta^{3}}}}}={\sqrt {\frac {An}{Rn\,la^{2}}}}\,la$
Planck mass	$m_{\text{P}}={\sqrt {\frac {\hbar c}{G}}}={\sqrt {\frac {An{\frac {la}{ta}}}{\frac {la^{3}}{Rn\,ta^{3}}}}}={\sqrt {\frac {An}{Rn\,la^{2}}}}\,Rn\,ta$
Planck energy	$m_{\text{P}}c^{2}={\sqrt {\frac {\hbar {c^{5}}}{G}}}={\sqrt {\frac {An{\frac {la^{5}}{ta^{5}}}}{\frac {la^{3}}{Rn\,ta^{3}}}}}={\sqrt {\frac {Rn\,la^{2}}{An}}}\,{\frac {An}{ta}}$
Planck temperature	$T_{\text{P}}\times k_{\text{B}}=m_{\text{P}}c^{2}={\sqrt {\frac {Rn\,la^{2}}{An}}}\,{\frac {An}{ta}}$
∴	${\frac {t_{\text{P}}}{ta}}={\frac {l_{\text{P}}}{la}}={\frac {m_{\text{P}}}{Rn\,ta}}={\frac {\frac {An}{ta}}{m_{\text{P}}c^{2}}}={\sqrt {\frac {An}{Rn\,la^{2}}}}$

The meaning of Planck units

The Planck length and time units are understood to represent the smallest meaningful size of each quantity. For example, the Planck length is the smallest meaningful length because looking at small objects through a microscope requires energy. If one were to build a microscope powerful enough to see objects at Planck length or smaller, the microscope would use so much energy that a black hole would form. In fact, it is generally understood that the existence of objects on the Planck scale would cause a black hole.

The Planck mass of 2.176434(24)×10^-8 kg is not a minimum value. In the case of mass, the Planck value is a crossover point. The Planck mass represents the boundary between gravitation and quantum mechanics. If an object has a mass larger than the Planck mass then gravitational effects will become more important. If the mass is smaller than the Planck mass then quantum mechanical effects will be more important.

Visible universe and the Bully Metric

Since Planck units represent the smallest meaningful length and time values, it seems appropriate to next consider the largest meaningful length and time value, and situate these within the Bully system. The universe is currently understood to be 13.7 billion years old, which is 14.15 × 10²⁷ ta in Bully units. The radius of the visible universe is 46.508 billion light years, which is 48.04 × 10²⁷ la in Bully units.

The apan prefix table

SI prefixes have the same meaning and conventions when used with apan variants as they have when used with standard SI units. See Table 3 below for the list of SI prefixes used with apan variants. Also shown in the table are the smallest (Planck scale) and largest (Visible Universe) values for each unit.

Mass, Momentum, and Energy are compound units in the Bully system.
