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.

    Theory. Cambridge, UK Cambridge University

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
    time-space 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).

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.

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 three-dimensional universe into
    an unseen fourth dimension.
  • Ex. Kaluza, an additional fifth spatial
    dimension unified Relativity and
    Electromagnetic Theory.
  • Kaluzas dimensions? Topologically, three are
    extended and one is tightly curled up much like
    Riemanns wrinkles.

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-f
    uture-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
    time-reversal 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.

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

9
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.
10
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 Newtons laws of
    motion. Since Newtons 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.

Three Principal Temporalities and Associated
Causalities
Five forms of causality and different ways of
extension in space supports my assertion that
each temporality is a dimension of a local
topology.

Eootemporal Block-universe and time-asymetric due to perturbation Inverse Square Law and diffusion Meaningless Deterministic

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 Characteristics (Continued)
  • Thus the local form of temporality at anyone
    point is restricted by equations defining the
    overall topological structure of the
    agent/landscapes 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 dont 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 simulations dimension except that imposed
    from outside
  • There is nothing special about a cells discrete
    spatial landscape position
  • Emergent patterns are a series of past screen
    shots assembled outside of simulations 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
