Abstract
A comprehensive physical theory explains all aspects of the physical
universe, including
quantum aspects, classical aspects, relativistic aspects, their
relationships, and
unification. The central nonlocality principle leads to a nonlocal
geometry that ex-plains
entire quantum phenomenology, including two-slit experiment,
Aspect-type
ex-periments,
quantum randomness, tunneling etc. The infinitesimal aspect of this
geom-etry
is a usual (differential) geometry, various aspects of which are
energy-momentum,
spin-helicity, electric, color and flavor charges. Their interactions are
governed by a mathematically automatic field equation—also a grand
conservation principle. New predictions: a new particle property;
bending-of-light estimates refined over relativity’s; shape of the
universe; a no gravitational singularity theorem; etc. Nonlocal physics is
formulated using a nonlocal calculus and nonlocal differential equations,
replacing inadequate local concepts of Newton’s calculus and partial
differential equations. Usual quantum formalisms followfrom our theory—the
latter doesn’t rest on the former.
1.1 Introduction
The primary purpose of a scientific theory is to understand complex
phenomena with
the aid of simpler and readily comprehensible concepts.
Modern physics is faced with
a great challenge—quantum phenomena. These still lack consistent
rational explanation
after a hundred years since their discovery. Most of the paradoxes of the
quantum theory are paradoxes of the theory rather than those of observed
phenomena. Clearly, a fresh consistent set of concepts are needed to
actually understand the seemingly bizarre quantum phenomena. Thus, we
abandon the entire opaque machinery of quantum mathematics and all its
interpretations. Aspect-type experiments reveal the inherent nonlocality
of the physical world. Hence, we also abandon the very basis of classi-cal
physics—the tacit assumption that phenomena are governed by local
mechanisms. Instead, we propose a nonlocal physics, constructed from
scratch. This physics also lays bare the integrated reality which
underlies all the myriad fields, particles, their properties, and their
fields.
Fortunately, this entire new conceptual framework can be deduced
from
one physical
principle, the nonlocality principle. The latter leads to a nonlocal
geometry, which
is specified by a nonlocal connection (as opposed to classical, local
connection in the sense of differential geometry). This nonlocal
connection explains entire quantum phe-nomenology on one hand while its
local aspect, a classical connection, is the universal field which yields
an integrated geometric description of all the forces, particles, fields,
energy-momentum, charges, and other quantum numbers.
Due to nonlocality, partial differential equations are inadequate to
predict events.
Thus, the local concepts of Newton’s calculus are inadequate to
completely describe
the physical world. While the classical physics is encoded in terms of
relationships among (local) rates of change of physical quantities, the
crucial concepts of nonlocal physics involve the way physical quantities
are related to each other nonlocally. Thus, the new laws should be
formulated as statements of these nonlocal relationships. For these
reasons, we devise a new nonlocal calculus and nonlocal differential
equations. Although this calculus correctly, and completely, encodes
nonlocal dependences among fields, the fields are still local in that they
are defined point-wise. The nonlocal connection mentioned above is not a
field defined point-wise. It is defined at ordered pairs of points; and
its value at a pair relates vectors and tensors at one point with those at
the other. To analyze this essentially nonlocal field and its various
aspects, we devise a calculus of nonlocal fields, along with a nonlocal
differential geometry. Then we write down the field equation, in terms of
concepts of this calculus. This equation governs all aspects of the
physical world.
We make no attempt to explain any of the current quantum formalisms,
nor
is any
consideration given to the paradoxes arising out of these formalisms. We
only explain observed physical phenomena. Our theory is formulated
completely using real numbers—noncommutative variables are not needed.
Besides explaining a great many unexplained phenomena, several
new
predictions
are deduced.
It can’t be over-emphasized that, while current theoretical trends in
science and philosophy actively shun determinism and rationality, our
theory brings us back to the realm of classical logic, and to a
determinism stronger than that of Newton’s. Ironically enough, this form
of determinism has plenty of room for ‘free will’, and it also causes the
apparent quantum randomness.
This report consists of seven sections, divided into to three chapters.
Chapter 1 introduces the nonlocality principle and explains quantum
phenomena. Chapter 2 ex-amine the fundamental field, which follows from
the nonlocality principle. Since this field is a nonlocal object and has a
local, infinitesimal aspect, the analysis takes three forms. The first
analyzes the local aspect using infinitesimal methods; i.e., using
New-ton’s calculus. Here, various aspects of the local aspect will be
identified with various properties of particles. Using these fields we can
build various particles, and the field equation mandates that they should
interact. As the information extracted from this analysis is inadequate to
exactly predict events, we next analyze the local aspect using a nonlocal
analysis. This yields a more natural set of equations encoding complete
information on the local aspect. We are still left with an unknown—the
nonlocal con-nection itself. This being a truly nonlocal object, we devise
a calculus for such objects. For more details, see the table of contents.
Chapter 3 lists several new predictions. We have systematically suppressed
much technical details and all proofs. An exhaustive discussion of
concepts and technical details, can be found in the forthcoming research
monograph, Principia Physica, by the author.
1.2 Nonlocal field
1.2.1 Nonlocality Principle
Classically, it is conceived that an individual event affects events
only in its immediate
vicinity, and this effect travels from point to point with definite
speed. The discovery
of a series of quantum effects, which culminated in Aspect-type
experiments, forces
us to abandon this classical, local, way of describing the physical
world. It has been
evident for at least fifteen years that the quantum world is ruled by
essentially nonlocal mechanisms, and there is no way to reduce this
nonlocality to classical local objects. We propose that this fact of the
physical world be adopted as a fundamental physical principle.
Thus, we propose a fundamentally different mechanism of how events
affect each
other. While the classical viewpoint is essentially local, we propose that
any two events (points) reflect events in each-other’s vicinity, and this
is an immediate reflection with-out any notion of a signal traveling from
one point to another. This may sound absurd at first, but its full
implications are very naturally intuitive and consistent with observation.
This is because at any given point x, the reflections from other points
add up to describe the events in the immediate neighborhood of x. For
example, the value of a field at a point is the sum of the values
reflected from all the other points of spacetime. Thus, even though each
point reflects events everywhere else, all points do not look the same.
Also, as we look at successive space-like sections, we perceive some
effects to be moving from point to point and with definite speeds. Thus,
although our hypothesis asserts a strong action-at-a-distance, its
cumulative effects may appear to be traveling from point to point with
definite speeds; consequently, the classical viewpoint is not
contradicted, but is supplemented at a more fundamental level. We call
this hypothesis of events being reflected in different neighborhoods the
nonlocality principle. This principle can be refined using mathematical
language. For this we need to define two basic concepts. Following
Einstein, we think of the universe as the set of events: each event
corresponding to a mathematical point in spacetime 1 ;butwe call them
point events instead, to underscore their exact conceptual content. Now we
define an event to be any set of point events. E.g., entire spacetime is
an event, and so is a single point event. Also, the trajectory (or part
thereof) of an electron is an event.
Now we formulate the nonlocality principle more precisely:
Spacetime, X; the set of point events, is a four-dimensional manifold,
such that every pair of point events, (x; y); is nonlocally connected in
the following sense:Each one of the neighborhoods Uand Vof point events x
and y; respectively, reflects events in the other: these reflections are
described by smooth maps between neighborhoods, and are asymptotically
exact; i.e. as the neighborhoods become smaller, the reflections converge
to inverse, one-to-one, and onto reflections. ones.
The seminal consequence of the principle, mentioned below, will
follow
regardless
of how we choose to formalize the asymtotic convergence (there are
several ways); so
we can afford to be vague about the latter—at least for the time being. We
can deduce entire physics from this single hypothesis. In particular, we
propose that nothing exists but this scheme of reflections between pairs
of points. Thus, our theory does not even assume the existence of matter,
energy, fields, particles etc.; rather, we deduce all these from the
nonlocality principle as formulated above.
The seminal consequence of the principle is that it implies a nonlocal
connection on spacetime. We use the word ‘connection’ in the sense that it
lets us compare vectors at any pair of points in spacetime. The classical
connection, as conceived in differential geometry, is local in the sense
that it is essentially a way of relating vectors at any point with those
in its immediate (infinitesimal) vicinity. A posteriori, it allows us to
compare...
[1 Actually it is possible to formulate the principle—without any
reference to a pre-existing spacetime—in
the mathematical language of categories; essentially by formalizing
the
way one arrives at the concept of
a point from that of a neighborhood. It is not clear whether this will add
to our understanding of physical phenomena, though.]
...vectors at distinct points through parallel transport along paths. We
note that this way of comparing vectors at distinct points depends on the
path along which one transports the vectors. This again points out the
fact that the classical connection is essentially an infinitesimal object
whose integral is the classical parallel transport. As opposed to that,
our nonlocal connection is nonlocal in the sense that it provides a means
of comparing vectors at any two distinct points directly, without any
primary notion of infinitesimal transport of vectors or the accompanying
path-dependant parallel transport. We will also show that this nonlocal
connection has an infinitesimal (local) aspect which is nothing but a
classical (local) connection. Our theory accomplishes three important
objectives:
(1) The nonlocal connection explains all quantum aspects of the
physical
world.
(2) The local, infinitesimal, aspect of this connection unifies all the
fields, particles, quantum numbers, charges, mass, energy, momentum, etc.
(3) It is devoid of singularities.
We observe that the quantum aspects are more apparent at smaller
scales
because
the nonlocal reflections grow more and more accurate as the
neighborhoods grow
smaller. The ‘rate’ at which these convergence to perfect accuracy
occurs depends
on the metric, and it will be shown that the latter is an arbitrary
choice in our the-ory.
Thus, the Planck’s constant, which seems very intimately related to this
rate, also seems to be dependant on our choice of the metric. We will not
go into this any further because we can formulate our entire theory
without any reference to it, or any other constants—dimensional or
dimensionless.
If an intuitive picture of the universe is sought, we can say that it is a
giant kalei-doscope, each point being an infinitesimal mirror reflecting
all other mirrors. Another metaphor would be a cross-section of a bundle
of optic fibers, which are fused together at one end into a single point.
Yet another visualization of these nonlocal connec-tions is the image of a
telephone exchange, where each point of spacetime corresponds to a
telephone; each phone being in direct instantaneous communication with all
the other phones. Then, cumulative information at each point may appear to
travel at finite speeds despite the underlying instantaneous communication
among the phones.
1.2.2 Preliminary consequences of the principle
Nonlocal affine connection
As a consequence of the principle, there exists a one-to-one
correspondence between
vectors at x and vectors at y. It is easy to visualize this
correspondence. Every vector
can be thought of as a tangent to a particle trajectory. Since events,
such as particle trajectories, are reflected between pair of
neighborhoods, we see that this induces a correspondence of vectors at
points in these neighborhoods. Mathematically, this correspondence is an
affine isomorphism from the tangent vector-space Tx at x to the tangent
vector-space Ty at y; roughly speaking, this isomorphism, say !xy; is the
‘affine derivative’ of the correspondence referred to in the nonlocality
principle. Thus, we have, for every pair of points in spacetime, a way to
compare vectors at one of the points with those at the other. This is
reminiscent of the notion of connection from differential geometry, which
lets us compare vectors at a point with those at points in its
infinitesimal neighborhood. This, the classical kind of connection, is
consequently a local connection. As opposed to that, what we have above is
best described as a non-local connection, say !, whose value at an ordered
pair of points (x; y) is the affine isomorphism !xy. Note that !xy and !yx
are inverse isomorphisms. Note that !xy naturally extends to the whole
tensor algebra at x:
Sum of reflections
Consider a fixed point x in spacetime. For any other point y, events
around y will be
reflected in events around x. For example, if an elementary physical
field F takes the
value F (y) at y, then it will contribute !yx(F (y)) to the value of the
field F at x. Here !yx(F (y)) is the value of the vector F (y) under the
map !yx. Thus, the field value at x is the sum of all these contributions
as y ranges over entire spacetime. This sum is described mathematically by
an integral 2 :
F (x) =Z !yx(F (y))dy (1.1)
Note that the integrand is a function on X with values in the
vector-space Tx.
We see that, elementary physical fields are extremely nonlocal objects in
the sense that values at each point depend on values at all other
points—not just nearby points.
1.3 Quantum consequences
1.3.1 Two-slit experiment
Because of equation (1.1) we can view an elementary particle as a
field
which may
appear localized in a portion of spacetime and yet be spread-out over
entire spacetime; e.g., we can visualize an electron as a very intense
region of a field. Now, since this part of the field is the sum-total of
the field everywhere else (see equation 1.1), it can also be viewed as
spread-out over entire spacetime. Reciprocally, this nonlocal summation
can give rise to intense regions in the field, which are dependant on the
values of the field everywhere else. Thus, discreteness and contiguousness
exist simultaneously, and yet in a non-contradictory way. Also, more
localized the particle-like phenomenon is, more it comes under the purview
of nonlocal connection, and more it manifests its wave-particle duality.
This is the basic picture to keep in mind when trying to understand
quantum phenomena. The two-slit experiment becomes immediately
comprehensible from this picture. As an aside, we mention that since
clumpiness naturally arises from the nonlocal character of spacetime, it
may explain COBE-type data and distribution of galaxies.
2 This integral is defined using a volume form on X; integrating
vector-valued functions component-wise.
The volume form is determined only up to a scalar multiple, but the
class of the permissible fields is
determined uniquely by this integral. Also, the physics is independent of
the choice of this form because the fields and equations are invariant
under this choice. If spacetime is compact (see Sec. 3.1.3), then there is
a unique volume form with integral 1:
1.3.2 Quantum randomness
Consider the history of an observer in time as a one-parameter family of
space-like sections of spacetime. Then, given a field, the nonlocality
principle implies that the observer will not be able to predict exactly
how the field will change over his own history. This is because the data
he has on the field is from the past and the present. He has no data on
the future slices. Since the value of the field at any point in spacetime
is directly dependant on that at every point, it is not possible in
general to predict the exact value of the field at any point using partial
differential equations and partial data. Since we recognize fields and
particles as the same entity, we see that it is not possible to predict
any event exactly as conceived in classical physics. Thus, the observer is
left with the feeling that the events are purely random, and he is led to
believe that physical objects such as particles don’t have physical
properties until they are observed. All the famous paradoxes of quantum
theory are based on this assumption and on the undue significance that the
process of measurement receives due to it.
1.3.3 Aspect-type experiments
The basic picture mentioned above also makes Aspect-type results
transparent, lending
a solid physical explanation for the violation of Bell’s inequality.
1.3.4 Quantum tunneling
This is just a manifestation of the apparent randomness and
unconnectedness of two
events: vanishing of a particle at one point, and its reappearance
elsewhere. The point
is that a particle doesn’t have to go through a wall to appear on the
other side. The field configuration over the whole spacetime, when viewed
as space-like slices, appears to evolve in such a way that it exhibits
local effects, such as presence of its particle on one side of the wall in
one instance, and on the other side in the next instance.
1.3.5 Deterministic choice
We have already noticed that the nonlocality principle is an expression of
an extreme form of determinism. Despite this, there is considerable room
for choice in this the-ory. Consider the case of an elementary field being
monitored by an observer. At any instance in time according to his frame
of reference, the field configuration in his past is already determined.
Taking into account the total nonlocal dependence of the field, one would
think that the field configuration in the future, too is completely
determined. This is not the case: Since the value of the field at any
point is given by an integral over X; there can be infinitely many
configurations, each differing another on at the most a set of measure
zero. Consequently, the future of the configuration has a fair degree of
freedom without the need to alter the past.

Structure of particles
Basic constructions
We propose that the observed particles/fields are nothing but the
manifestations of the
field
with varying intensity of the constituent fields. For instance,
electron is a
field/particle whose only nonzero components are (i) negative charge
field (ii) energy-momentum
field (iii) spin-helicity field. Similarly, we view leptons, quarks, and
so-called gauge bosons as particles/fields with various combinations of
nonzero field components.
Interactions
All the elementary fields interact because they have to satisfy equation
(2.5). All the interactions are built into this equation.
Conservation and source-supply symmetry
We have already mentioned the tentative modified conservation laws.
We
also know
that under this scheme, every field splits into a source field, and the
corresponding supply field (traceless part), and because of the
conservation laws, the source can con-vert into supply and vice versa.
Thus, under right circumstances, we should be able to observe electric
charge convert into electromagnetic field, and energy-momentum convert
into pure gravitation. More generally, an electric charge may convert into
pure gravitation or vice versa.
2.2 Local Aspect: Nonlocal analysis
2.2.1 Inadequacy of partial differential equations
Since the value of an elementary field at a point depends on its value at
every other point, the system of equations we have are completely
over-determined. It is obvious that because of the nonlocal
interdependence of values of the fields, the partial differ-ential
equations can not predict the exact events unless we know the field at
(almost) all points—in which case, equations are not needed! Thus, it
would be impossible to solve any initial-value or boundary-value problems.
It follows that the nonlocal char-acter of the universe forces us to
abandon description in terms of partial differential equations and forces
us to adopt some nonlocal concepts for description, so we would be able to
compute empirical predictions. Furthermore, in a nonlocal universe, it is
only natural that laws of physics are best formulated in terms of nonlocal
concepts. For these reasons, we introduce nonlocal calculus and nonlocal
differential equations in the next section. We then formulate the
fundamental nonlocal field equation. This equation contains lot more
information on our fields than does the local equation. Note that fields
analyzed here are local but the analysis is nonlocal. In the following
sections we will analyze nonlocal fields.
2.2.2 Nonlocal calculus of fields
[See original paper for mathematical analysis]
2.3 Nonlocal aspect: Nonlocal analysis
The most fundamental structure on spacetime is the nonlocal
connection
!: This is an
example of what we will call a (nonlocal) form. Unlike the usual fields,
this field is defined at an ordered pair of points, and is an isomorphism
from the tangent space of the first point to that of the other. In order
to analyze !; we develop an analysis of such forms.
Chapter 3
THE CONCLUSION
3.1 Predictions
3.1.1 Rotation of polarization of Light
The new field spun-heluxicity, the traceless part accompanying the
field
spin-helicity
(2.1.3), would rotate the polarization of light 1 (and other such
‘directed’ properties)
just like curvature bends light.
3.1.2 Bending of light near magnetars
Since electromagnetism is a non-metric aspect of the universal
connection, given a
stellar object, such a magnetar, with an immense magnetic field that is
comparable in curvature to its gravitational field, bending of light
should be significantly different than that predicted by general
relativity.
3.1.3 Causality and compactness
Since a metric is just a convention of a frame of reference, there is no
absolute concept of causal character of vectors. Consequently, the concept
of a closed time-like curve has no absolute meaning. Indeed, given a
closed curve, we can always find a metric with respect to which it is
time-like. Thus, it is not possible to avoid closed-loop con-tradictions
(such as an individual killing his own parents before he was conceived)
even if the spacetime is non-compact. In short, the mathematical deduction
that spacetime must be non-compact (if causal), has no absolute meaning
and is not very useful. If we were to preserve this kind of causality,
instead of restricting ourselves to non-compact spacetime, we should
identify frames of references ( which includes a choice of met-ric) that
prohibit closed time-like curves; and then declare these the only
physically permissible ones. A similar discussion holds for other
causality conditions such as strong causality, etc.
[1 Just before the submission of this paper, it was pointed out to the
author that such phenomena have already been observed.]
3.1.4 No-singularities and big-bang
The general conservation principle (2.2) implies that if the gravitation
part of curva-ture increases than the non-gravitational part will
compensate for it. Consequently, black-hole type situation can’t lead to
singularities. This mechanism that prevents sin-gularities can be
interpreted as a sort of anti-gravity, which is not an extra force of
nature, but is built into our theory by virtue of the grand conservation
law (2.1). The lack of absolute metric implies that there are no absolute
notions of expansion and contraction of space. Thus, expansion is not an
absolute feature of the universe; big-bang is an actual point of
spacetime, and is no different than any other point in the spacetime.
3.1.5 Parallelizability and shape of spacetime
Nonlocality principle implies that spacetime is parallelizable and
hence
orientable, and
this removes the possibility of Moebius-strip type circumstances from our
physical uni-verse. Also, it follows from last two sections, that the
hypothesis of complete (‘without holes’) and compact spacetime is viable;
and this combined with parallelizability can restrict the shape of
spacetime in very significant ways—if it is boundary-less. Also, the above
discussion can be brought to bear on the recent cosmological observations
of Class 1-a supernovae. Currently, these observations are interpreted by
saying that the spacetime has negative large-scale curvature. But this
interpretation assumes that the connection of the universe is the
Levi-Civita connection of a metric. Our theory implies that the connection
of spacetime has non-metric components as well; and it is this connection
whose curvature is negative with respect to the metric g. Thus, the
gravitation part of the connection need not have negative curvature. This
removes the restriction on the shape of the (space-like sections of)
universe that it must be a hy-perbolic 3-manifold, and this in turn saves
us from the implication that spacetime (if compact) should be a multiply
connected manifold.
3.1.6 Micro predictions
Corresponding to the field spun-heluxity, there is a new particle
property, which should
be inferable from observation of rotation mentioned in section (3.1.1) in
particle inter-actions, as well.
Our viewpoint also validates particles of other fields such as sound
and
heat when
these are determined at micro-scales, e.g. in solid-state. More
generally, we predict
anyons corresponding to any conceivable physical field determined at
extremely small
scale.

Hi Gary,
The author seems to be a mathematician, but he does not write as a
mathematician. He is vague at important point. Therefore I can not
proceed linearly.... I have to study his "theorems" to see what are
his assumptions and definitions. I do not like being forced to do it, but
that how it is. Will tell you when getting at some clear assesment of the

P.S. The very idea of a "nonlocal connection" is not a new one.
Physicists were studying "bilocal field theories" fifty years ago!

Dear Collegue,
thanks for your kind interest in the paper.
if we had required that f(x) = y, then the natural candidate would be the
"ordinary derivative"....i.e. a LINEAR map from tangent space at x to that
at y. But as things stand f(x) maybe a point differnt than y. so we have a
linear map (the derivative) from tangent space at x to that at f(x)...now
we apply our principle to the pair f(x) and y....again there is a
derivative map form tangent space at f(x) to that at f(f(x)), and we
appply the prinicple to the pair of paoints f(f(x)) and y....we repeat the
process and get successive linear maps from f^n(x) to f^(n+1)(x)...for
each n we have a compisiton from tangent space at x to that of f^n(x)...it
can be show that the sequence of points f^n(x) converges to y and the
wbove compistion converges to a linear map from tnagent space at x to that
at y. But we have an extra pice of information...the sequence of points
f^n(x)....this determines a vector at y. so what we have is a Linear map
from x to y AND vector at y. In short, we have an AFFINE map form x to y
(tangent spaces at these)....this map is what i calle "roughly speaking,
an 'affine derivative of f'"....i hope this clarifies the vague allusion
to the term affine. If you have any further questions in this regard,
please feel free to write. Sincerely, Mukul Patel
