Elements and Pro esses of Reality
Antonio Leon. May 2024.
Abstra t.-This arti le re alls the on ept of element of reality and introdu es a new more general on ept: the pro ess of
reality, whi h in ludes the rst one, the on ept of hange and the irreversibility of time. The problem of quantum non-lo ality
is also dis ussed and a new dis rete s enario with a single universal lo ality is suggested.
Keywords: quantum lo ality, realism, element of reality, pro ess of reality, arrow of time, ellular automata.
1 Introdu tion: innity and history
Con erning the importan e of the history of the
universe in the quantum debate on reality and lo ality,
it seems to me onvenient to begin by remembering that
things happen; and then immediately add: things happen
and leave tra es that we an re ognize, interpret and
onrm in experimental terms. This is what seems to
have been happening in the observable universe for at
least the last 13.8 billion years. And sin e it is only what
it seems, we will need a guiding prin iple to onstru t
our dis ussion of that observable reality, we will all it
the Prin iple of Dire tional Evolution:
In the literature related to the strangeness of quantum
me hani s that I have had the opportunity to examine, I
have always been stru k by the onstant absen e of two
issues of apital importan e in the possible unraveling of
this strangeness (one has the impression that strangeness
adds value to ontemporary physi al theories). The rst
of these issues is the hypothesis of the a tual innity,
subsumed in the Axiom of Innity, whi h underlies
the mathemati s with whi h physi ists onstru t their
theories, in luding quantum me hani s. The se ond is

and sin e both assumptions (lo ality and realism)
were inalienable for them, they ended up de laring
quantum me hani s in omplete. But the argumentative
variations on EPR and their orresponding experimental
veri ations gave reason to the opposite on lusion:
reality is not lo al, for instan e, elementary parti les an
be inuen ed instantaneously and at arbitrary distan es.
Moreover, and a ording to some interpretations of
quantum me hani s, it is not possible to deta h observers
from the observed physi al fa ts. The question we pose
here is what role do the elements and pro esses of reality
play in the explanation of the physi al world?
A ording to the formal s enario introdu ed above,
the observable universe ould not have originated by
itself and had to have a rst ause unknowable in terms
of other known auses. It is a universe that, moreover,
evolves always in the same dire tion and under the
ontrol of the same set of formally onsistent laws. This
is what it has been doing for 13.8 billion years, with no
observers to inuen e the results. Consequently, it an
be armed that all intera tions, mi ro and ma ros opi ,
ausing the dire tional evolution of the universe have
always o urred in the same dire tion in whi h they
would have to o ur, otherwise su h dire tional evolution
would be impossible. An evolution arried out through
trillions of reality pro esses, ae ting trillions of reality
elements and leaving trillions of empiri ally veriable
proofs (trillions is a way of speaking).
We an, therefore, on lude this part of the dis ussion
by suggesting an autonomous, observer-independent
evolution of the observable universe. An evolution that
has nely produ ed ons ious observers who wonder
about the reality of the pro esses from whi h they
themselves have emerged. Pro esses of reality that have
left a multitude of observable eviden e onrming the
autonomy of the dire tional evolution of the universe. It
may be that ertain experiments, mental or real, require
more exoti and observer-dependent explanations, but
that does not seem to be the ase for the unobserved
physi al obje t that the universe has been for most of its
history. Interpretations of quantum me hani s that link
a tive observations to observed fa ts should onsider the
dire tional and autonomous evolution of the universe.
Previously we proved that either (1) the
quantum-me hani al des ription of reality
given by the wave fun tion is not omplete
or (2) when the operators orresponding
to two physi al quantities do not ommute
the two quantities annot have simultaneous
reality. Starting then with the assumption
that the wave fun tion does give a omplete
des ription of the physi al reality, we arrived
at the on lusion that two physi al quantities,
with non- ommuting operators, an have
simultaneous reality. Thus the negation of
(1) leads to the negation of the only other
alternative (2). We are thus for ed to on lude
that the quantum-me hani al des ription of
physi al reality given by wave fun tions is not
omplete.
And as is well known the story ontinued in theoreti al
terms with Bell's theorem [5℄ and the GHZ states
[10℄; and in experimental terms with the respe tive
experiments arried out sin e 1982 [4, 3, 20, 11, 7℄, all of
whi h ended up proving the Copenhagen interpretation
was not wrong.
3 Pro esses of reality
It is not possible to dene everything: we would fall into a
potentially innite regress of denitions. For that reason
we are obliged to use in all s ien es primitive on epts,
on epts that are not dened in terms of other more basi
on epts; if we did, those more basi on epts would be
the new primitive on epts. Whi h justies B. Russell's
ironi words that in mathemati s we never know what
we are really talking about [19℄, although some do seem
to know what they are talking about.
The on epts of hange, event, modi ation, transformation and pro ess are intimately related and surely all
of them are primitive on epts, of whi h it is not possible
to give non- ir ular denitions. We have to onstru t
our arguments with this inevitable restri tion, whi h,
although it should not be forgotten, should not stop us
in our eagerness to understand the physi al world. We
will then say that if an element of reality, observed or
not, is modied in su h a way that another element of
reality always results and the modi ation always leaves
the same observable tra es, then that modi ation is a
pro ess of reality.
Naturally, the pro esses of reality in lude the elements
of reality and their modi ations or hanges. They also
in lude the passage of time. Therefore, it is a ri her
on ept than EPR's element of reality. The in lusion of
the on ept of hange is really important. Indeed, the
problem of hange has been posed and not solved for 25
enturies. What is worse, physi s, the s ien e of hange,
has ompletely forgotten the old problem of hange, as
if it were possible to explain the physi al world without
having previously solved the problem of hange. On the
other hand, it an be proved that the problem of hange
has no solution in the spa etime ontinuum, but it does
have a solution in a dis rete model of spa e and time.
[16, p. 293-302℄ [14, p. 502-512℄.
The EPR argument made its authors on lude that
quantum me hani s was in ompatible with lo al realism,
4 The universe as a unique lo ality
The elements and pro esses of reality serve to
de ouple the dire tional evolution of the universe from
observation. But they do not solve the problem of
quantum non-lo ality. In this nal se tion we suggest a
new way of dis ussion in whi h the spa etime ontinuum
is repla ed by a dis rete spa e and time, with indivisible
minimum units: qseats and qbeats respe tively. And
the substitution is not arbitrary, among other reasons
be ause:
1. The innite sets, su h as the ontinuum, are
in onsistent (see one of the proofs in the nal
appendix).
2. The vibrations of spa e are empiri ally dete table
(gravitational waves) and therefore spa e must be a
real physi al obje t: that whi h does not exist neither
vibrates nor an modify the length of the arms of the
interferometers that dete t gravitational waves.

3. Spa e and time are involved in numerous
mathemati al fun tions whose outputs must be
dis rete values of energy, whi h is impossible if
ontinuous variables are involved in these fun tions.
Therefore, if energy is dis rete, spa e and time must
also be dis rete.
4. The problem of hange an only be solved in a
dis rete spa e and time [14, 12℄. And without solving
the problem of hange it is impossible to explain the
physi al world.
5. Dis rete spa e is mu h simpler than the spa e
ontinuum: if a qseat had a Plan k volume,
the observable universe (9.9 billion light years in
diameter) would ontain 7.6 × 10184 qseats, while any
arbitrary volume of the spa e ontinuum ontains the
same non-numerable innite number of points: 2ℵo .
6. Dierent regions of dis rete spa e ontain dierent
numbers of qseats, whereas a Plan k volume and the
entire universe, whatever its a tual size, have the
same number of points: 2ℵo points.
7. In a dis rete spa e-time it is possible to dene models
in whi h all qseats evolve in unison, the whole system
being the same deterministi lo ality.
on e ompared with all elements of Q01 , the urrent value
of x were not the least rational in Q01 , there would exist
at least one element f (n) in Q01 su h that f (n) < x.
But this is impossible a ording to (1). Therefore, it
was ompared with f (n) and redened as f (n). So, it
is impossible that f (n) < x. But it is also immediate
to prove that: On e ompared with all elements of Q01 ,
the urrent value of x is not the smallest rational in that
set. In ee t, on e ompared with all elements of Q01 ,
and whatsoever be the urrent value of x, ea h element
of the innite set {x/2, x/3, x/4 . . . } is an element of
Q01 less than x. This ontradi tion proves the Axiom
of Innity legitimizing the existen e of Q01 as an a tual
(not potential) innite totality is in onsistent.
(1) This is formally proved by indu tion in [16℄, and
an also be proved by Modus Tollens and by supertask
theory.

There is a model ompatible with all the above

the quantum lo ality problem ould be solved: ellular
automata (of whi h quantum versions are also available
[9, 18, 2, 6℄). This may seem an extravagant model,
although I nd the alternative of multiple universes mu h
more extravagant. A tually, I am not proposing that the
universe is a ellular automaton, but suggesting a hange
of perspe tive in the interpretation of quantum me hani s, a new perspe tive based on the nite and dis rete
nature of spa e and time in a universe in whi h all its
dis rete elements are a tualized in unison, as in ellular
automata.

The Axiom of Innity is in onsistent.
Proof.-The open interval of rational numbers (0, 1) is
denumerable and densely ordered. So, it an be put in
one-to-one orresponden e f with the set N of natural
numbers in their natural order of pre eden e; and the
interval (0, 1) an be rewritten as the set Q01 =
{f (1), f (2), f (3), . . . }. Let now x be a rational variable
initially dened as f (1); and let (the urrent value of)
x be ompared with the su essive elements f (1), f (2),
f (3). . . so that x is redened as f (i) if, and only if, f (i)
is less than the urrent value of x. Sin e, a ording
to the Axiom of Innity, all elements f (1), f (2), f (3), . . .
of Q01 are rational numbers whi h exist as a omplete
totality, x an be su essively ompared with all of
them:
∀n ∈ N : x is ompared with f (n), and
redened as f (n) i f (n) < x

value of x is the smallest rational in that set. Indeed, if
