1. Introduction
The universe began with the Big Bang, which is a current prevailing scientific opinion. But this Big Bang was not an explosion of 4-dimensional spacetime, which also is a current prevailing scientific opinion, but an explosion of dimensions. More precisely, in the
-dimensional void, a 0-dimensional point appeared, inducing the appearance of countably infinitely other points indistinguishable from the first one. The breach made by the first operation of the
dimensional successor function of the Peano axioms inevitably continued leading to the formation of 1-dimensional, real and imaginary lines allowing for an ordering of points using multipliers of real units (ones) or imaginary units (
). Then out of two lines of each kind, crossing each other only at one initial point
, the dimensional successor function formed 2-dimensional
,
, and
Euclidean planes, with
being a mirror reflection of
. And so on, forming
n-dimensional Euclidean spaces
with
real and
imaginary lines,
, and the scalar product defined by
where
. With the onset of the first 0-dimensional point, information began to evolve [
1,
2,
3,
4,
5,
6].
However, dimensional properties are not uniform. Concerning regular convex
n-polytopes in natural dimensions, for example, there are countably infinitely many regular convex polygons, five regular convex polyhedra (Platonic solids), six regular convex 4-polytopes, and only three regular convex
n-polytopes if
[
7]. In particular, 4-dimensional euclidean space is endowed with a peculiar property known as exotic
[
8]. This property allowed for variation of phenotypic traits within populations of individuals [
9] and extended the evolution of information into biological evolution. Each biological cell perceives emergent Euclidean
space of three real and one imaginary (time) dimension observer-dependently [
10] and at present when
is
real; perceived space requires an integer dimensionality [
11]. This is the emergent dimensionality (ED) [
5,
9,
12,
13,
14].
Each dimension requires certain units of measure. In real dimensions, the
natural units of measure were derived by Max Planck in 1899 as "independent of special
bodies or
substances, thereby necessarily retaining their meaning for all times and for all civilizations, including extraterrestrial and non-human ones" [
15]. Planck units utilize the Planck constant
h that he introduced in his black-body radiation formula. However, already in 1881, George Stoney derived a system of natural units [
16] based on the elementary charge
e (Planck’s constant was unknown at that time). The ratio of Stoney units to Planck units is
, where
is the fine-structure constant. This study derives the complementary set of natural units applicable for imaginary dimensions, including the imaginary base units, based on the discovered negative fine-structure constant
. Similarly, the ratio of
-Stoney units to
-Planck units is
. As the speed of electromagnetic radiation is the product of its wavelength and frequency and both these quantities are imaginary in imaginary dimensions, some real but negative parameter
corresponding to the speed of light in vacuum
c (i.e., the natural speed) is also necessary as
. It turns out that the imaginary Planck energy
and temperature
are larger in moduli than the Planck energy
and temperature
setting more favorable conditions for biological evolution to emerge in
Euclidean space than in
Euclidean one due to the minimum energy principle.
The study shows that the energies of neutron stars and white dwarfs exceed their mass–energy equivalences and that excess energy is stored in imaginary dimensions and is inaccessible to direct observations. This corrects the value of the photon sphere radius and results in the upper bound on the size-to-mass ratio of their cores, where the Schwarzschild radius sets the lower bound.
The paper is structured as follows.
Section 2 shows that Fresnel coefficients for the normal incidence of electromagnetic radiation on monolayer graphene include the second, negative fine-structure constant
as a fundamental constant of nature.
Section 3 shows that by this second fine-structure constant nature endows us with the complementary set of
-natural units.
Section 4 introduces the concept of a black-body
object in thermodynamic equilibrium, emitting perfect black-body radiation, and reviews its necessary properties.
Section 5 introduces complex energies of masses, charges, and photons expressed in terms of real and imaginary Planck units introduced in
Section 3 and discusses equilibria formed by comparing their moduli.
Section 6 applies these equilibria to black-body
objects to derive the range of their size-to-mass ratios and the equilibrium ratio.
Section 7 applies this range to the observed mergers of black-body
objects to show that the observed data is explainable with no need to introduce hypothetical exotic stellar
objects.
Section 8 define complex forces to derive a black-body
object surface gravity, and the generalized Hawking radiation temperature.
Section 9 summarizes the findings of this study. Certain prospects for further research are given in the appendices.
2. The Second Fine-Structure Constant
Numerous publications provide Fresnel coefficients for the normal incidence of electromagnetic radiation (EMR) on monolayer graphene (MLG), which are remarkably defined only by
and the fine-structure constant
where
is the Planck charge,
is vacuum permittivity (the electric constant),
ℏ is the reduced Planck constant, and
e is the elementary charge. Transmittance (T) of MLG
for normal EMR incidence was derived from the Fresnel equation in the thin-film limit [
17] (Eq. 3), whereas spectrally flat absorptance (A)
was reported [
18,
19] for photon energies between about
and
[eV]. T was related to reflectance (R) [
20] (Eq. 53) as
, i.e,
The above equations for T and R, as well as the equation for the absorptance
were also derived [
21] (Eqs. 29-31) based on the thin film model (setting
for substrate). The sum of transmittance (
3) and the reflectance (
4) at normal EMR incidence on MLG was derived [
22] (Eq. 4a) as
where
is the vacuum impedance
is the MLG conductivity [
23], and
is the electric susceptibility of vacuum. These coefficients are thus well-established theoretically and experimentally confirmed [
17,
18,
19,
22,
24,
25].
As a consequence of the conservation of energy
In other words, the transmittance in the Fresnel equation describing the reflection and transmission of EMR at normal incidence on a boundary between different optical media is, in the case of the 2-dimensional (boundary) of MLG, modified to include its absorption.
The reflectance
(
4) of MLG can be expressed as a quadratic equation with respect to
This quadratic equation has two roots with reciprocals
Therefore, the equation (
9) includes the second, negative fine-structure constant
. It happens that the sum of the reciprocals of these fine-structure constants (
10) and (
11)
is remarkably independent of the value of the reflectance R. The same result can only be obtained for
(cf.
Appendix A). This result is intriguing in the context of a peculiar algebraic expression for the fine-structure constant [
26]
that contains a
free term and is very close to the physical definition (
2) of
, which according to the CODATA 2018 value is
. Notably, the value of the fine-structure constant is not
constant but increases with time [
27,
28,
29,
30,
31]. Thus, the algebraic value given by (
13) can be interpreted as the asymptote of the
increase.
Using relations (
12) and (
13), we can express the negative reciprocal of the 2
fine-structure constant
that emerged in the quadratic equation (
9) also as a function of
only
and this value can also be interpreted as the asymptote of the
decrease, where the current value would amount to
, assuming the rate of change is the same for
and
.
Using relations (
13) and (
14), T (
3), R (
4), and A (
5) of MLG for normal EMR incidence can be expressed just by
. Moreover, equation (
9) includes two
-like constants for two surfaces with positive and negative Gaussian curvatures (cf.
Appendix B).
3. Set of -Planck units
For further analysis, we have to use Planck units over the Stoney units as only the former incorporate
(and
h). Planck units can be derived from numerous starting points [
5,
32] (cf. Appendices
Appendix C and
Appendix D). The definition of the Planck charge
can be solved for the speed of light yielding
. Furthermore, the ratio of charges in the definition of the fine-structure constant
(
2) applied for the negative
, requires an introduction of some imaginary Planck charge
so that its square would yield a negative value of
and since the elementary charge
e is real
Among the physical constants of the
term, almost all are positive
1. Only the
parameter, corresponding to the speed of light
c, is negative as both frequency
and wavelength
are imaginary in imaginary dimensions. Therefore, the equation (
16) can be solved for
yielding
which is greater than the speed of light in vacuum
c in modulus
2. We also note that
c is defined by the electric constant
and the magnetic constant
as
; a square root is bivalued and the value of
depends on
. Furthermore,
c is defined by
-dependent vacuum impedance (
7).
The negative parameter
(
17) leads to the imaginary Planck charge
, length
, mass
, time
, and temperature
that redefined by square roots containing
raised to odd (1, 3, 5) powers become imaginary and bivalued
3
and furthermore can be expressed, using the relation (
31), in terms of base Planck units
,
,
,
, and
.
Planck units derived from the imaginary base units (
19)-(
21) are generally not imaginary. The
Planck volume
the
Planck momentum
the
Planck energy
and the
Planck acceleration
are imaginary and bivalued. However, the
Planck force
and the
Planck density
are real and bivalued. On the other hand, the
Planck area
is strictly negative, while the Planck area
is strictly positive. In the following, we shall call the units (
18)-(
29)
-Planck units.
Both
and
lead to the second, negative vacuum impedance
Solving both impedances (
7) and (
30) for
and comparing with each other yields the following important relation between the speed of light in vacuum
c, negative parameter
, and the fine-structure constants
,
where, notably,
is the electron’s velocity at the first circular orbit in the Bohr model of the hydrogen atom. This is not the only
to
relation. Along with the two
-like constants
,
(relations (
A15) and (
A17), cf.
Appendix B)
The relations between time (
21) and temperature (
22)
-Planck units are inverted,
,
, and saturate Heisenberg’s uncertainty principle (energy-time version) taking energy from the equipartition theorem for one degree of freedom (or one bit of information [
5,
33])
Furthermore, eliminating
and
from the relations (
18)-(
20), yield
and
Base Planck and Stoney units themselves admit negative values as negative square roots. By choosing complex analysis, within the framework of ED, we enter into bivalence by the very nature of this analysis. All geometric
objects have both positive and negative volumes and surfaces [
14] equal in moduli. On the other hand, imaginary and negative physical quantities are the subject of research. In particular, the subject of scientific research is thermodynamics in the complex plane. Lee–Yang zeros, for example, have been experimentally observed [
34,
35]. We note here that the imaginary Planck Units are not imaginary due to being multiplied by the imaginary unit
i. They are imaginary due to the negativity of odd powers of
being the square root argument; thus, they define imaginary physical quantities inaccessible to direct measurements
4. They do not apply only to the time dimension but to any imaginary dimension. However, in our four-dimensional Euclidean
space-time, Planck units apply in general to the spatial dimensions, while the imaginary ones in general to the imaginary temporal dimension. All the
-Planck units have physical meanings. However, some are elusive, like the negative area or imaginary volume, which require two or three orthogonal imaginary dimensions.
Planck charge relations (
2), (
16), and the charge conservation principle imply that the elementary charge
e is the same both in real and imaginary dimensions since
where
is the Stoney charge. There is no physically meaningful
elementary mass that would satisfy the relation (
20)
Neither is there a physically meaningful
elementary (and imaginary)
length satisfying the relation (
29)
(which in modulus is almost 1660 times smaller than the Planck length), or an
elementary temperature abiding to (
22)
and close to the Hagedorn temperature of grand unified string models.
Thus, as to the modulus, charges are the same in real and imaginary dimensions, while masses, lengths, temperatures, and other derived quantities that can vary with time, may differ (the dimensional character of the charges is additionally emphasized by the real
multiplied by
i in the imaginary charge energy (
54) and imaginary
in the real charge energy (
55)). We note that the same form of the relations (
36) and (
37) reflect the same form of Coulomb’s law and Newton’s law of gravity, which are inverse-square laws.
4. Black Body Objects
There are only three observable
objects in nature that emit perfect black-body radiation: unsupported black holes (BHs, the densest), neutron stars (NSs), supported, as it is accepted, by neutron degeneracy pressure, and white dwarfs (WDs), supported by electron degeneracy pressure (the least dense). We shall collectively call them black-body
objects (BBOs). This term is not used in standard cosmology, but standard cosmology scrunches under embarrassingly significant failings, not just
tensions as is sometimes described, as if to somehow imply that a resolution will eventually be found [
36]. Entropic gravity [
33] explains galaxy rotation curves without resorting to dark matter, has been experimentally confirmed [
37], and is decoherence-free [
38]. It has recently been experimentally confirmed that the so-called
accretion instability is a fundamental physical process [
39]. We conjecture that this process is common for all BBOs. Furthermore, the term
object as a collection of
matter is a misnomer, as it neglects quantum nonlocality [
40] that is independent of the entanglement among the
particles [
41]. Thus we use emphasis for (indistinguishable)
particle and (distinguishable)
object, as well as for
matter and
distance. These terms have no absolute meaning in ED. In particular, given the recent observation of
quasiparticles in classical systems [
42].
As black-body radiation is radiation of global thermodynamic equilibrium, it is patternless (thermal noise) radiation that depends only on one parameter. In the case of BHs, this is known as Hawking radiation and this parameter is the BH temperature
corresponding to the BH diameter [
5]
, where
. As black-body radiation is patternless, the triangulated [
5] BBOs contain a balanced number of Planck area triangles, each carrying binary potential
, as it has been shown for BHs, based on Bekenstein-Hawking (BH) entropy. BH entropy can be derived from the Bekenstein bound
which defines an upper limit on the thermodynamic entropy
S that can be contained within a sphere of radius
R having energy
E. After plugging the BH (Schwarzschild) radius
and mass-energy equivalence
, where
is the BH mass, into the bound (
40), it reduces BH entropy. In other words, BH entropy saturates the Bekenstein bound (
40).
The patternless nature of the perfect black-body radiation was derived [
5] by comparing BH entropy with the binary entropy variation
([
5] Eq. (55)), valid for any holographic sphere, where
denotes the number of active Planck triangles with binary potential
. Thus, the entropy of all BBOs is
where
is the information capacity of the BBO surface, i.e., the
Planck triangles (where "
" is the floor function that yields the greatest integer less than or equal to its argument
x) corresponding to bits of information [
33,
43,
44], and the fractional part triangle(s) having the area
to small to carry a single bit of information. Furthermore,
.
We shall define the generalized radius of a BBO having mass
as a function of
multiplier
and the generalized BBO energy
as a function of
multiplier
Plugging definitions (
42) and (
43) into the Bekenstein bound (
40) it becomes
and equals the BBO entropy (
41) if
. Thus, the energy of all BBOs having a radius (
42) is
with
in the case of BHs and
for NSs and WDs. We shall further call the coefficient
k the
size-to-mass ratio.
BHs are fundamentally uncharged since the parameters of any conceivable BH, in particular charged (Reissner–Nordström) and charged-rotating (Kerr–Newman) BH, can be altered arbitrarily, provided that the BH area does not decrease [
45] by means of Penrose processes [
46,
47] to extract BH electrostatic and/or rotational energy [
48]. Thus any BH is defined by only one real parameter: its diameter (cf. [
5] Figure 2(b)), mass, temperature, energy, etc., each corresponding to the other. We note that in the complex Euclidean
space, an
n-ball (
) is spherical only for a vanishing imaginary dimension [
14]. As the interiors of the BBOs are inaccessible to an exterior observer [
43], BBOs do not have interiors
5, which makes them similar to interior-less mathematical points. Yet, a BH can embrace this defining parameter. That means that three points forming a Planck triangle corresponding to a bit of information on a BH surface can store this parameter and this is intuitively comprehensible: the area of a spherical triangle is larger than that of a flat triangle defined by the same vertices, providing the curvature is nonvanishing, and depends on this curvature, i.e., this additional parameter defines it.
On the other hand, it is accepted that in the case of NSs, electrons combine with protons to form neutrons so that NSs are composed almost entirely of neutrons. But it is never the case that all electrons and all protons of an NS become neutrons. WDs are charged by definition as they are accepted to be composed mostly of electron-degenerate
matter. But how can a charged BBO store both the curvature and an additional parameter corresponding to its charge? Fortunately, the relation (
36) ensures that charges are the same in real and imaginary dimensions. Therefore each
charged Planck triangle of a BBO surface is associated with three
Planck triangles, each sharing a vertex or two vertices with this triangle in
. And this configuration is capable of storing both the curvature and the charge. The Planck triangle
and the
imaginary Planck triangle
, which has a smaller area in modulus, can be considered in a polyspherical coordinate system, in which gravitation/acceleration acts in a radial direction (with the entropic gravitation acting inwardly and acceleration acting in both radial directions) [
5], while electrostatics act in a tangential direction.
Not only BBOs are perfectly spherical. Also, their mergers, to which we shall return in
Section 7, are perfectly spherical, as it has been recently experimentally confirmed [
49] based on the registered gravitational event GW170817. One can hardly expect a collision of two perfectly spherical, patternless thermal noises to produce some aspherical pattern instead of another perfectly spherical patternless noise. Where would the information about this pattern come from at the moment of the collision? From the point of impact? No point of impact is distinct on a patternless surface.
The hitherto considerations may be unsettling for the reader, as the energy (
45) of BBOs other than BHs (i.e., for
) exceeds mass-energy equivalence
, which is the limit of the maximum
real energy. In the subsequent section, we shall show that a part of the energy of NSs and WDs is imaginary and thus unmeasurable.
5. Complex Energies and Equilibria
A complex energy formula
where
and
represent respectively real and imaginary energy of an
object having mass
and charge
6 was proposed in [
50]. Equation (
46) considers real (i.e., physically measurable) masses
and charges
. We shall modify it to a form involving real and imaginary physical quantities expressing them, where deemed appropriate, by Planck units
where uppercase
M,
Q, and
denote respectively masses, charges, and wavelengths, while the subscripts
i refer to imaginary quantities. We note that the discretization of charges by integer multipliers
q of the elementary charge
e is far-fetched, considering the fractional charges of
quasiparticles.
We define the following two complex energies, the complex energy of real mass and imaginary charge
of real charge and imaginary mass
of real photon (energy or frequency
) and imaginary mass
of real photon and imaginary charge
of real mass and imaginary photon (with frequency
)
and of real charge and imaginary photon
where
,
,
.
Complex energies (
48)-(
53) link mass, charge, and photon energies within the framework of ED. We note in passing that using the different speed of light parameters in energies (
48) and (
49) yields a contradiction (cf.
Appendix E).
Energies (
48), (
49), (
51), and (
53) yield two different quanta of the charge energies corresponding to the elementary charge, the imaginary quantum
and the - larger in modulus - real quantum
Furthermore, , . We note that photon energy vanishes for the infinite wavelength.
The squared moduli of the energies (
48)-(
53) are
where we used relations (
20), (
25), (
31), and (
47).
Postulating that the squared moduli (
56) and (
57) are equal
we demand a mass-charge energy equilibrium condition from which we can obtain the value of the imaginary mass
as a function of mass
M and charge
Q in this equilibrium
In particular for
this yields
Since mass
is imaginary by definition, the argument of the square root in the relation (
63) must be negative
This means that masses of uncharged micro BHs () in thermodynamic equilibrium can be arbitrary. However, micro NSs and micro WDs, also in thermodynamic equilibrium, are inaccessible for direct observation, as they cannot achieve a net charge . Even a single elementary charge of a white dwarf renders its mass comparable to the mass of a grain of sand.
We note here that only the masses satisfying
have Compton wavelengths larger than the Planck length [
5]. Comparing this bound with the bound (
65) yields the charge multiplier
q corresponding to an atomic number
of a hypothetical element, which - as we conjecture - sets the limit on an extended periodic table and is a little higher than the accepted limit of
(unoctquadium). More massive elements would have Compton wavelengths smaller than the Planck length, which is physically implausible.
Postulating that the squared moduli (
60) and (
61) are equal
we demand a photon-charge energy equilibrium condition from which we can obtain the value of the imaginary photon energy
corresponding to the real photon energy
and charge
Q in this equilibrium
Since
is imaginary, we demand
to ensure that
. Thus
which, using mass-energy equivalence, corresponds to the bound (
65). We can also obtain the maximum wavelength in this equilibrium corresponding to the charge. For
it is
with
corresponding to the bound (
66).
It seems that no meaningful conclusions can be derived by postulating the equality of the squared moduli (
58) and (
59). Such a mass-photon energy equilibrium is an equation with four unknowns. Neither physically meaningful elementary mass (
37) nor length (
38) is common for real and imaginary dimensions.
Postulating the equality of all the squared moduli (
56)-(
61) to some constant energy
we demand a mass-charge-photon equilibrium condition, which can be solved for
A. Subtracting moduli (
56) and (
60) yields
, and similarly subtracting moduli (
57) and (
61) yields
. This equates moduli (
58) and (
59). Substituting
into the modulus (
61) and subtracting from the modulus (
56) yields
Subtracting this from (
58) or (
59) yields
which substituted into the relation (
71) yields
Finally, substituting the relation (
73) into the modulus (
56) yields
6. BBO Complex Energy Equilibria
We can interpret the modulus of the generalized energy of BBOs (
45) as the modulus of the complex energy of real mass (
56), taking the observable real energy
of the BBO as the real part of this energy. Thus
leads to
representing a charge surplus energy exceeding
. For
,
vanishes, confirming the vanishing net charge of BHs. Similarly, we can interpret the modulus of the generalized energy of BBOs (
45) as the modulus of the complex energy of real charge (
57). Thus
Substituting
from the relation (
76) into the relation (
77) turns the equilibrium condition (
63) into a function of the size-to-mass ratio
k instead of the charge
q
which for BHs (
) also corresponds to the relation (
64) between uncharged masses
M and
, where no assumptions concerning the BBO energy were made.
Furthermore, the argument of the square root in the relation (
78) must be negative, as mass
is imaginary by definition. This leads to the maximum size-to-mass ratio
where
satisfies the mass equilibrium (
78). Relations (
76) and (
78) are shown in
Figure 1.
The maximum size-to-mass ratio
(
79) sets the bounds on the BBO energy (
45), mass, and radius (
42)
In particular, using relations (
47),
or
. As WDs are the least dense BBOs, this bounds define the maximum radius and mass of a WD core.
Furthermore, relations (
65) and (
79) set the bound on the BBO minimum mass in the equilibrium (
62)
where
defines a condition in which neither
nor
can be further increased to reach its counterpart (defined respectively by
and
) in the bound (
81). Thus, for example, 1-bit BBO (
) corresponds to
,
-bit BBO (
) corresponds to
, while the maximum atomic number
(
66) corresponds to
In the case of a BBO, we obtain the equilibrium condition (
70) by comparing the squared moduli (
56)-(
61) of the energies (
48)-(
53) with the squared BBO energy (
45) which yields a solvable system of six nonlinear equations with six unknowns
Substituting
from
to
recovers the Compton wavelength of the BBO,
, in its Planck units form
. Furthermore, by substituting
and the Compton mass
into
, and comparing the LHSs of
and
we obtain the BBO equilibrium size-to-mass ratio
where
satisfies the equilibrium condition (
70) for
The equilibrium
(
85) and the maximum
(
79) size-to-mass ratios are related as
. Also, the following relations can be derived from the relations (
84) for the BBO in the equilibrium
(
85)
The BBO in the energy equilibrium bearing the elementary charge () would have mass , imaginary mass , wavelength , and imaginary wavelength .
These results show that the radius (
42) of charged BBOs is a continuous function of
satisfying the BBO entropy relation (
41), a necessary condition of patternless perfect black body radiation [
5].
Notably,
, where
is the size-to-mass ratio of a radius of the maximal sustainable density for gravitating spherical
matter given by Buchdahl’s theorem, and 3 is the size-to-mass ratio of a BH photon sphere radius
7. This hints that
is a true photon sphere radius, where BBO gravity, charge, and photon energies remain at equilibrium. Aside from the Schwarzschild radius (derivable from escape velocity
of mass
M by setting
), all the remaining thresholds of general relativity, such as Buchdahl’s threshold or a photon sphere radius, are only crude approximations. General relativity neglects the value of the fine-structure constants
and
, which, similarly as
or the base of the natural logarithm, are the fundamental constants of nature.
7. BBO Mergers
As the entropy (Boltzmann, Gibbs, Shannon, von Neumann) of independent systems is additive, a merger of BBO
and BBO
having entropies (
41)
and
, produces a BBO
having entropy
which shows that a merger of two primordial BHs, each having the Planck length diameter, the reduced Planck temperature
(the largest physically significant temperature [
12]), and no tangential acceleration
[
5,
12], produces a BH having
which represents the minimum BH diameter allowing for the notion of time [
12]. In comparison, a collision of the latter two BHs produces a BH having
having the triangulation defining only one precise diameter between its poles (cf. [
5] Figure 3(b)), which is also recovered from Heisenberg’s Uncertainty Principle (cf.
Appendix C).
Substituting the generalized radius (
42) into the entropy relation (
91) yields
which establishes a Pythagorean relation between the generalized energies (
45) of the merging components and the merger
valid both for
and
.
It is accepted that gravitational events’ observations alone are able to measure the masses of the merging components and set a lower limit on their compactness, but the results do not exclude mergers more compact than neutron stars such as quark stars, black holes, or more exotic
objects [
51]. We note in passing that describing the registered gravitational events as
waves is misleading. Normal modulation of the gravitational potential, caused by rotating (in the merger case - inspiral) bodies, is wrongly interpreted as a gravitational wave understood as a carrier of gravity [
52].
The accepted value of the Chandrasekhar WD mass limit, preventing its collapse into a denser form, is
[
53] and the accepted value of the analogous Tolman–Oppenheimer–Volkoff NS mass limit is
[
54,
55]. There is no accepted value of the BH mass limit. The conjectured value is
. The masses of most of the registered merging components are well beyond
. Of those that are not, most of the total or final masses exceed this limit. Therefore these mergers were classified as BH mergers. Only a few were classified otherwise, including GW170817, GW190425, GW200105, and GW200115. They are listed in
Table 1.
The relation (
93) explains the measurements of large masses of the BBO mergers with at least one charged merging component without resorting to any hypothetical types of exotic stellar
objects such as
quark stars. Interferometric data, available online at the Gravitational Wave Open Science Center (GWOSC) portal
8, indicate that the total mass of a merger is the sum of the masses of the merging components. Thus
We initially assume as negative masses, similarly to negative lengths, are inaccessible for direct observation, unlike charges.
We can use the BBO equilibrium relations (
84) to derive some information about the merger from the relation (
93).
with the first inequality (
94) lead to
which, by the charge conservation principle, implies mixed (positive and negative) charges of the merging components satisfying
. On the other hand,
with the first inequality (
94) lead to
But
with the inequality (
95) lead to an apparent contradiction
while
with the inequality (
97) lead to
with the inequality (

and so on (

)
Additivity of entropy (
91) of statistically independent merging BBOs, both in global thermodynamic equilibrium, defined by their generalized radii (
42), introduces the energy relation (
93). This relation, equality of charges in real and imaginary dimensions (
36), and the BBO equilibrium relations (
84) induce not only mixed charges but also imaginary, negative, and mixed wavelengths and masses during the merger. A BBO merger spreads in all dimensions, not only the observable ones, as a gravitational event associated with a fast radio burst (FRB) event, as it has recently been reported [
56] based on GW1904251 gravitational event and FRB 20190425A event

In the observable dimensions during the merger, the size-to-mass ratio
decreases making the BBO
denser until it becomes a BH for
and no further charge reduction is possible (cf.
Figure 1). From the relation (
92) and the first inequality (
94) we see that this holds for
Table 1 lists the mass-to-size ratios
calculated according to the relation (
93) that provide the measured mass
of the merger and satisfy the inequality (
101). Mass-to-size ratios
and
of the merging components were arbitrarily selected based on their masses, taking into account the
NS mass limit.
8. BBO Complex Gravity and Temperature
Complex energies (
48)-(
53) define complex forces (similarly to the complex energy of real masses and charges (
46), [
50] Eq. (7)) acting over real and imaginary
distances . Using the relations (
47), we obtain the following products
defining six complex forces acting over a real
distance ,
and six complex forces acting over an imaginary
distance ,
where
and
, and
With a simplifying assumption of
, the forces acting over a real
distanceR are stronger and opposite to the corresponding forces acting over an imaginary
distance even though the Planck force is lower in modulus than the (real)
-Planck force (
27). We excluded mixed forces (based on real and imaginary masses/charges/photons) as real and imaginary dimensions are orthogonal.
In particular, we can use the complex force
(
105) with (
102) (i.e., complex Newton’s law of universal gravitation) to calculate the BBO surface gravity
, assuming an uncharged (
) test mass
where
,
. Substituting the BBO equilibrium relation (
76) and the generalized BBO radius (
42)
into the relation (
108) yields
which reduces to BH surface gravity for
, in modulus
equals to a squared BH surface gravity for all
k, and in particular,
The BBO surface gravity (
109) leads to the generalized complex Hawking blackbody-radiation equation
describing the BBO temperature
10 by including its charge in the imaginary part, which also in modulus equals squared BH temperature
.
In particular,
reduce to a BH temperature for
. We note that for
,
(where
) has the magnitude of the Hagedorn temperature of strings.
It seems, therefore, that a universe without imaginary dimensions (i.e., with
) would be a black hole. Hence, the evolution of information [
1,
2,
3,
4,
5,
6] requires imaginary time. And we cannot zero
as we would have to neglect graphene.
9. Discussion
The reflectance of graphene under the normal incidence of electromagnetic radiation expressed as the quadratic equation for the fine-structure constant
includes the 2
negative fine-structure constant
. The sum of the reciprocal of this 2
fine-structure constant
with the reciprocal of the fine-structure constant
(
2) is independent of the reflectance value R and remarkably equals simply
. Particular algebraic definition of the fine-structure constant
, containing the free
term, can be interpreted as the asymptote of the CODATA value
, the value of which varies with time. The negative fine-structure constant
leads to the set of
-Planck units applicable to imaginary dimensions, including imaginary
-Planck units (
18)-(
26). Real and imaginary mass and charge units (
34), length and mass units (
35) units, and temperature and time units (
33) are directly related to each other. Also, the elementary charge
e is common for real and imaginary dimensions (
36).
Applying the
-Planck units to a complex energy formula [
50] yields complex energies (
48), (
49) setting the atomic number
as the limit on an extended periodic table. The generalized energy (
45) of all perfect black-body
objects (black holes, neutron stars, and white dwarfs) having the generalized radius
exceed mass-energy equivalence if
. Complex energies (
48), (
49) allow for storing the excess of this energy in their imaginary parts, inaccessible for direct observation. The results show that the perfect black-body
objects other than black holes cannot have masses lower than
and that the size-to-mass ratios of their cores cannot exceed
defined by the relation (
79). It is further shown that a black-body
object is in the equilibrium of complex energies if its radius
(
85). It is conjectured that this is the correct value of the photon sphere radius. BBO fluctuations for
and
are briefly discussed in
Appendix F. The proposed model explains the registered (GWOSC) high masses of the neutron stars mergers without resorting to any hypothetical types of exotic stellar
objects.
In the context of the results of this study, monolayer graphene, a truly 2-dimensional material with no thickness
11, is a
keyhole to other, unperceivable, dimensionalities. Graphene history is also instructive. Discovered in 1947 [
58], graphene was long considered an
academic material until it was eventually pulled from graphite in 2004 [
59] by means of ordinary Scotch tape
12. These fifty-seven years, along with twenty-nine years (1935-1964) between the condemnation of quantum theory as
incomplete [
60] and Bell’s mathematical theorem [
61] asserting that it is not true, and the fifty-eight years (1964-2022) between the formulation of this theorem and 2022 Nobel prize in physics for its experimental
loophole-free confirmation, should remind us that Max Planck, the genius who discovered Planck units, has also discovered Planck’s principle.
