Physicists unreflectively Assert That:
“If string theory is correct, we must entrain the
possibility that space-time has more than four
dimensions. The number of time dimensions must be
kept equal to one — it seems very difficult if not
altogether impossible, to construct a consistent theory
with more than one time dimension. The extra
dimensions must therefore be spatial.”
Dynamical simulation may be a less difficult way to
investigate the formation of complex entities in multiple
time dimensions with multiple space dimensions.
Barton Zwiebach (2004). A First Course in String Theory. Cambridge, UK: Cambridge University Press, p.28.
TIME STRUCTURES
The Basic Problem
•
Assumptions:
–
Biological, physical, and social entities continually form themselves according to
heterochronically complex, interwoven morphodynamical rules. “Entities” are really
ordered synced processes existing in time-ecologies.
–
There are Five time-space dimensions causally nested in everyday life: notemoral,
biotemporal, eotemporal, prototemporal, and atemporal.
–
A time-ecology can be for example, encompass a specific policy sector regulated via its own
extended geophysical, social, and mental spaces all of which are instantiated in multiple timespace dimensions. A time-ecology involves multiple levels and complex past-present-future
feedbacks.
•
Describing and Understanding:
– For a simulation we are looking at a space-time topology problem involving mapping of
differing space-time event streams that continuously form a time-ecology of developing agents
and landscapes according to complex systems dynamics
•
Experimenting:
–
Translating and combining these five temporal dimensions, including temporal orientation and
perspective, into a realistic simulation has not been done to my knowledge
Characteristics of Time
The “time” of a time-ecology is
background independent and local
– Time is local resulting from continuously changing local
topologies as delimited by five temporal levels of nested
causalities in space including that forming/enacted by the entity
– Temporal background independence produces local outcomes
that emerge from changes in the relational streams of
propagating events
– Each local event stream has varying temporal progressions and
perceptions (capacity to move in and to receive varying kinds of
information, energy or resources)
– These flows are continuously structurating forms be they called
"agent" or "landscape" or “network.” Remember, everything is
instantiated in a time-ecology
– “This is not existence within time; existence is time.”
(Goodhew and Loy, 2002).
TIME STRUCTURES
Characteristics of Time (Continued)
•
Social Decision windows present opportunities to take action to change the
temporal and socio-economic growth and development of a time budgets
•
Time budgets in turn regulate the heterochrony of event flows in a time-ecology or
complex system (called chronocomplexity)
•
Space-time is inseparably entwined with the topology of the space-time dimensions
of a local point in a dynamical flow
– Topology includes both mathematical and phenomenological “places”
•
The space-time topological structure of a universe is the structure of the arena in
which the processes that comprise the history of that universe occur. This involves
“place” (space), in the sense of “to place” or topos
•
The topology of space-time involves local proximity and envelopment as
continuity, connectivity, and orientability, all of which express the depth or
thickness of time-space dimension as a local organization that can be moved, even
acted through.
•
Thus, local space-time topology permits variations in placement and envelopment
practices regulating heterochronic flows of energy, information, and resources
according to chronocomplex laws as they converge into propagating flow patterns
(velocity cones) across a time-ecology. Such local space-time topological patterns
are symmetry conserving as a pattern moves forward or backward in a time.
Evolution may selectively change a time-ecology and break such symmetries.
TIME STRUCTURES
Characteristics of Time (Continued)
Proximity, envelopment, posture and placement define how process is
instantiated at the point in a flow of the space-time topological dimensions.
In all cases it is the particular deformation of the dimensional topology of the space
that determines how objects are instantiated.
• Ex. A paper with a two dimensional “point” can be crumpled. 2D
movement over crumple experiences a “force” making it impossible to
move in a straight line under specific local conditions
• Ex. Riemann: gravity was “caused by the crumpling of the threedimensional universe into an unseen fourth dimension.”
• Ex. Kaluza, an additional fifth spatial dimension unified Relativity and
Electromagnetic Theory.
•Kaluza’s dimensions? Topologically, three are extended and one is
tightly curled up much like Riemann’s wrinkles.
TIME STRUCTURES
Five Temporalities and Associated Causalities
•
Nootemporal: a noetic (symbolic) intentionality.
– Propagates via networks but does not propagate uniformly and does feedback from the future into the past
and visa versa;
– Noetic time chunking: Past-future-present-future-future-past-present.
– Causality is omnidirectional with neither the past nor the future being fully determined.
•
Biotemporal: The inner developmental and growth organization of life.
– Patterned living things go through developmental life cycles with beginnings, middles, and ends.
– Biotemporality is strictly local, is bounded in space-time (birth-death) and propagates through short range
networks (sexuality, simple division, etc),
– Distinguishes past and future relative to developmental and growth processes.
– Human agents have characteristic temporal noetic intentionality that accompany each stage.
– Causality is unidirectional but is open to natural selection as a process for selecting heterochronic “wild”
rhythms giving birth to novelty.
•
Eotemporal: The universe of large scale matter. This time is physicist's “t”.
– Eotemporality is the block universe of large scale matter
– It is characterized the simultaneous existence of all presents in the block-universe (no flow) with timereversal symetry.
– Eotemporal time obeys the inverse square law propagating uniformly, and has No feedback from the
future into the past making causality unidirectional or (Gödel: flows from the future into the past making
any direction in time impossible) SEE NEXT SLIDE
– Causality is deterministic.
Not Concerned here with:
•
Prototemporal: is the time of elementary objects such as quarks, photons, etc. Causality is probabilistic and stochastic
•
Atemporal: the mode of time characteristic of a black hole. There is no mode of causation
TIME STRUCTURES
Eotemporality: The Block Universe
• Affords equal (ontological) status to all points in space-time, thus
regarding temporality as an illusory human construct with no
reference to reality as understood by modern physics.
• “Nothing singles out a privileged special moment as the present or
any process that would systematically turn future events into the
present, then past, events. In short, ... time does not pass or flow.“*
• Think of the universe as a large block of events. The events we
would like to call future, past, and present all exist "timelessly" in the
block universe, with certain geometric [topological?] relationships
between them.
• Simultaneity is relative to a frame of motion.
•
*Paul Davies, "That Mysterious Flow“
Determinism in the Eotemporal Block
Universe
The relationship described in above holds between any time slices of
the universe, and thus, given the laws, the present implies the future
and also the past. We are free to take the present as fundamental in
the relationship of determination as much as we are free to take any
other time slice as fundamental. In fact, no time slice, no state of the
universe at a time, is fundamental.
According to this view there is a disconnect between the “block
universe” that we exist in and causal laws which give direction to
physical processes.
Eotemporal 2nd Law is Double NOT
Single Headed
• Various Physical Laws are “time asymmetric” in defining “arrows of
causality” like the second law of thermodynamics. Entropy
increasing apparently gives time an arrow.
• But, the Second Law is derivative of the statistical application of
Newton’s laws of motion. Since Newton’s laws of motion have no
built-in temporal orientation, then systems may evolve towards
greater entropy in either the future or the past. (Greene, p160) Thus
there is an overwhelming probability that a system had greater
entropy in both the future and the past. Gravity provides the arrow.

TIME STRUCTURES
Time Characteristics (Continued)
Different topological geometries can be distinguished
by what is allowed in rotational transformations at a
point in the time-ecology.
– Ex. different particles emerge from the way various dimensions
of space are rotated about a point. Rotating a photon out of 4
D space into 8 D space creates a photino in 8 D space.
– The important point is that the qualities of the formed event are
different (Stewart, 2001).
– The above example suggests that rotation through five time
dimensions produces varying topological qualities in
placement and proximity.

TIME STRUCTURES
Time Characteristics (Continued)
• Thus the local form of temporality at anyone “point” is
restricted by equations defining the overall topological
structure of the agent/landscape’s respective five
dimensional space-times, and, by their rates of rotation.
(Calabi-Yau spaces for example)
• Topological spatial dimensions can be large and
extended or small and curled up. We don’t know how to
visualize time dimensions yet. Remember, each of our
five temporalities extend themselves differently.
• Varying space dimensions (four or more) have been
explored using projections and shadows (Banchoff,
1996). How to visualize temporal dimensions?

Current CA Temporal Barriers
•
Two Dimensional topology with one dimension of background dependent time, not five in
background independent time
•
Placement, proximity, and performance rules are imposed from another dimension that
does not change with the simulations dimensions
•
No memory, no past or other time relationship in the simulation’s dimension except that
imposed from outside
•
There is nothing special about a cell’s discrete spatial landscape position
•
Emergent patterns are a series of past screen shots assembled outside of simulation’s
time. They are not all simultaneously present in the “present”. Clearly biotemporality can
not be depicted in such space-time
•
Nootemporal time which should play a significant role does not demonstrate both forward
and backward causal symmetry
•
•
.
Future is highly problematic because it does not approach at all in nootemporal time, but
emerges from agent/landscape interaction (computer machine time)
There are multiple local “presents” across a time-ecology constantly structurating multiple
developmental patterns, not one
