Mass in the Universe

Measurement Quantization (MQ) provides a count-based description of the mass associated with the universe. Rather than introducing the total mass of the universe as an independently fitted cosmological quantity, MQ relates mass to elapsed fundamental count, the fundamental measures, and the geometry connecting the Internal Frame and System Frame. Within this description, the mass-equivalent allocation associated with the universe increases with elapsed count at a fixed rate.

This construction is closely related to the MQ descriptions of the diameter and age of the universe, mass accretion, dark matter, and dark energy. Together, these relations connect universe-scale mass allocation to the fixed referenceability-domain fractions of the expanding universe.

Referenceability-Domain Fractions

MQ describes five related referenceability-domain quantities. These are not five independent spatial components. They are mutually constrained dimensionless fractions derived from the same expanding-frame geometry. The canonical domain partitions are fixed constants and are therefore written upright.

The fundamental referenceability-domain fraction is ${\mathrm{\Omega }}_{\mathrm{f}}=\frac{2}{{{\theta }_{\mathrm{si}}}^2}$. The visible fraction is ${\mathrm{\Omega }}_{\mathrm{vis}}=\frac{2}{{\theta }_{\mathrm{si}}({{\theta }_{\mathrm{si}}}^2+2)}$, while the observable fraction can be written ${\mathrm{\Omega }}_{\mathrm{obs}}=\frac{2{\mathrm{\Omega }}_{\mathrm{f}}}{{\mathrm{\Omega }}_{\mathrm{f}}+1}$. The remaining fractions follow from ${\mathrm{\Omega }}_{\mathrm{uobs}}={\mathrm{\Omega }}_{\mathrm{obs}}-{\mathrm{\Omega }}_{\mathrm{vis}}$ and ${\mathrm{\Omega }}_{\mathrm{dk}}=1-{\mathrm{\Omega }}_{\mathrm{obs}}$.

The visible domain, ${\mathrm{\Omega }}_{\mathrm{vis}}$, is the portion presently referenceable by observation. The unobserved domain, ${\mathrm{\Omega }}_{\mathrm{uobs}}$, is the portion of the observable domain that is not presently visible but can become referenceable as additional elapsed time accumulates. Together they constitute the observable domain, ${\mathrm{\Omega }}_{\mathrm{obs}}$. The complementary dark domain, ${\mathrm{\Omega }}_{\mathrm{dk}}$, is permanently non-referenceable within this geometry. The fundamental domain, ${\mathrm{\Omega }}_{\mathrm{f}}$, provides the geometric pivot used in constructing these relationships.

These fractions are derived from the MQ geometric constant ${\theta }_{\mathrm{si}}$. Their interpretation should therefore be distinguished from measured or fitted cosmological density parameters. MQ investigates quantitative correspondences between these independently derived geometric fractions and observed cosmological phenomena, but the domain fractions are not defined by those observations.

From Elapsed Count to Mass

The mass construction begins with the elapsed universe-age count. Let $A_U$ denote the age of the universe and $t_f$ the fundamental time measure. The corresponding elapsed count $n_{\mathrm{Tu}}$ is $n_{\mathrm{Tu}}=\frac{A_U}{t_f}$.

The universe-scale fundamental mass allocation $M_f$ is then

Here, $m_f$ is the fundamental mass measure. The distinction between $m_f$ and $M_f$ is important. The former is the fundamental mass measure itself. The latter is the universe-scale mass-equivalent allocation constructed from the elapsed count relation. Because $n_{\mathrm{Tu}}$ increases with elapsed time, the associated universe-scale allocation increases with cosmic age.

The total mass-equivalent count $n_{\mathrm{Mu}}$ and elapsed time count determine the accumulated total mass-equivalent content. The resulting central relation is

The fixed referenceability geometry determines the relative allocation among domains, while elapsed fundamental count determines the absolute mass scale. This separates a geometric partition from the time-dependent quantity to which that partition applies.

Mass-Allocation Rate

The universe-scale rate follows from the same count geometry. Expressed in SI units, its canonical form is

Here, $l_f$ is the fundamental length measure. In fundamental units, the corresponding rate is $M_{\mathrm{acr}}=\left(\frac{n_{\mathrm{Mu}}}{n_{\mathrm{Tu}}}\right)\frac{{{\theta }_{\mathrm{si}}}^3}{2}=17.3611207370\left(89\right)$ units of $m_f$ per unit $t_f$.

This is an intrinsic mass-allocation rate in the MQ description. It should not be confused with the conventional astrophysical use of accretion to describe existing matter falling onto stars, galaxies, compact objects, or other gravitational systems. The relation instead describes the universe-scale count structure associated with mass-equivalent availability.

Pre Mass Allocation and Post Mass Accretion

The MQ formulation distinguishes pre mass allocation from post mass accretion. Pre mass allocation describes the intrinsic geometric allocation of fundamental mass availability established before later gravitational accretion. Post mass accretion describes the subsequent gravitational redistribution of that available mass into observable cosmic structures.

Within the Internal Frame, the underlying description is count-based. Through the Frames mapping, those count relations are expressed as realized physical quantities in the System Frame. This distinction separates the allocation relation from the later gravitational organization of the mass made available by that relation.

It also clarifies why the domain fractions can remain fixed while their associated mass-equivalent allocations increase. The fractions are geometric constants determined by ${\theta }_{\mathrm{si}}$. The absolute mass-equivalent content depends on elapsed count. At a common epoch, the geometry therefore retains the same fractional structure while the mass scale associated with it changes.

Cosmic Age and Total Mass

Because the mass-allocation rate is fixed in the MQ description, resolving the age of the universe supplies the elapsed duration needed to determine its corresponding universe-scale mass-equivalent allocation. MQ independently connects cosmic age with the geometry of the expanding universe and the cosmic microwave background.

This creates an internal connection among cosmic age, fundamental count, mass-equivalent content, and observational referenceability. The total is determined by elapsed count, while ${\mathrm{\Omega }}_{\mathrm{vis}}$, ${\mathrm{\Omega }}_{\mathrm{uobs}}$, ${\mathrm{\Omega }}_{\mathrm{obs}}$, ${\mathrm{\Omega }}_{\mathrm{dk}}$, and ${\mathrm{\Omega }}_{\mathrm{f}}$ provide fixed geometric fractions associated with that scale.

The construction therefore differs from treating cosmic mass and cosmic age as unrelated inputs. In MQ, length, mass, and time arise from a common discrete-measure structure developed in the physical significance of measure. Discrete relations reside in the Internal Frame. Through the Frames mapping, those relations are realized as dimensional physical quantities in the System Frame.

The mass of the universe is consequently tied to the same count geometry that determines its age, dimensions, and referenceability domains. The referenceability-domain fractions remain fixed, while the universe-scale mass-equivalent allocation increases with elapsed fundamental count at the rate derived above.
