Since Mermin  recasted the results of Hardy’s Gedankenexperiment  of entangled states for two quantum particles with the maximum nonlocal effect in
the form of a power of the Golden Mean giving
this quantum entanglement probability P was shown by the outstanding Egyptian physicist El Naschie to describe the many puzzling features of our universe very well such as dark energy, negative gravity or accelerated expansion of the universe  .
In this short contribution, I want to complete a previous publication  and will describe the mass respectively energy constituents of our universe solely by Hardy’s probability of quantum entanglement of two quantum particles, pointing to an unexpected reciprocity relation between mass constituents of the universe.
Besides the E-infinity theory of El Naschie  , the recently developed Information Relativity Theory (IR), created by Suleiman  , should attract our attention, too. This theory offers a new physical interpretation of the dynamics of matter-wave duality confirming the de Broglie-Bohm interpretation of the Quantum Theory    . The chosen time respectively length transformations automatically involve the Golden Mean, which is the basic building unit of the E-infinity theory. According to the IR approach, the maximum kinetic energy density of a moving body at a recession velocity β = v/c = φ is derived being φ5 
Indeed, this transformation equation for the kinetic energy density in terms of the recession velocity β resembles the maximum quantum entanglement probability P of two quantum particles given by Hardy  respectively Mermin 
  . (3)
Both mentioned theories (E respectively IR), if they can be brought into line, in the end, will have a lasting effect on our thinking and the perception of our existence.
2.1. Reciprocity Relation and Hardy’s Entanglement Probability
According to given results of the set-theoretical approach of E-infinity describing the five-dimensional Kaluza-Klein spacetime   , the amount of baryonic matter of the universe emerges as
(about 4.51%). (4)
The dark matter amount can be recast in the very simple form of
(about 22.18%). (5)
It may not be pure fortuity but nevertheless surprising that both amounts show a reciprocity relation. This can be seen, if we write down the remaining dark energy amount as the difference to the entire mass in a more persuasive form
(about 73.31%). (6)
Such coincidence means that both mass constituents should not be considered independent of each other. Mathematically, reciprocity is found, for instance, if one considers volume in comparison to surface, or particles in comparison to waves. Relevant topological arguments from the set theory are summarized by El Naschie  . However, the denominator factor of 100 in Equation (5) may be interpreted as a coupling term equal to the normed dimensions of the universe  .
The entire dark constituents yields
By the way, the simple result of 5φ2 represents the five-dimensional surface of the pre-quantum wave being the cobordism of the topological volume of φ5 of the Kaluza-Klein five-dimensional manifold    .
The estimated constituents are fairly well consistent with measurements of the Wilkinson Microwave Anisotropy Probe mission (WMAP)  .
El Naschie recently pointed out that D = φ−5 = 11 + 0.0901699… obviously represents the fractal dimension DM of Witten’s M-theory   .
Because φ−5 = 11 + φ5, its beautiful hierarchical form (or continued fraction representation) can be expressed as
in contrast to the most unique representation for the Golden mean
2.2. Alternative Approach Using Archimedes’ Constant π
An alternative approach for the mass constituents of the universe by applying the Archimedes’ constant π instead of φ yields almost equal amounts in comparison to results according to Equations (4) to (7)  
for the sum of the dark constituents (matter and energy). It may turn out in the future whether this replacement may be of any physical importance. However, some numerical approximations connect Hardy’s entanglement probability with Archimedes’ constant π and the inverse of Sommerfeld’s fine structure constant , respectively 
2.3. Hardy’s Entanglement Probability and Superconductivity
If one deals with particle entanglement, superconductivity represents a physical phenomenon suspecting such property. Some years ago, the present author suggested linking the optimum hole doping σo of high-Tc superconductors with Hardy’s φ5 entanglement probability  . The fractal-hierarchical structure of electrons entangled in pairs obviously determines this optimum near a quantum critical point that can be linked on the one hand with the universal fractal constant δ1 = 8.7210972 … of the renormalized quadratic Hénon map (remember the quadrilateral layer structure of the cuprates)
on the other hand with Hardy’s entanglement probability
this time connecting φ and π, the most important universal numbers of the cosmos.
The quotient of the Fermi speed to the Klitzing speed would yield
which is again proportional to  .
The fractal nature of electronic response in superconductors was documented some years ago by scanning tunneling microscopy   and is consistent with generated d-wave fractal patterns in superconductors as a consequence of antiferromagnetism  .
This contribution points to a reciprocity relation between the mass constituents of the universe that suggests their common physical interrelation. The obtained baryonic respectively dark mass amounts are related to Hardy’s maximum particle entanglement probability, namely the fifth power of the Golden Mean. Importantly, it is recommended once more to replace the Golden Mean φ in the mass relations by the Archimedes’ constant π to utilize very simple expressions that await further interpretation. The competition between the two numbers obviously determines what the realities of our universe are. However, a Nature article just published reporting on a galaxy lacking dark matter halo is reason enough to re-evaluate the statements given here  . The opportunity opens to do an acid test with Suleiman’s theory  . The author’s real interest in the cosmological relations including entanglement considerations is to catch an idea about the possible dark side of superconductivity.
