"There isn't a precise instant underlying an object's motion," he said. "And as its position is constantly changing over time -- and as such, never determined -- it also doesn't have a determined position at any time."

Heisenberg uncertainty: DxDp >= hbar/2 As the observed expansion of the universe continues, and, as the mean temperature of the universe continues to approach absolute zero, could the universe transform into a condition analogous to a "Bose Einstein condensate"?
At the foundation of classical logic is the law of excluded middle,
A|~A|A V ~A
T_|F||__T
F_|T||__T
This forms an invariance principle which is a symmetry
T|F = F|T = T
John Nash gives a most excellent equation for spacetime:

Remarks added 22 May 2002: The remarks below are given as they were in a (memo) note that wasn't generally accessible. Now I am not really updating it, but since the equation (vacuum) itself is now included on my "web page" it is time also to include these remarks. At the present time I think the "input" of the gravitational action of matter, etc. might be studied in terms of boundary value problems. Then on one side of a boundary there could be the vacuum equation to be satisfied. And there are some ideas that relate to this. But these are ideas that call for further study.
3 memo of May 31, 2001: The equation is tensor equation which has a parallel or similarity to "wave" equations and can be described in terms of a d'Alembertian operator. It is thought of as of interest as an alternative description of the general relativistic space-time continuum that allows for "compressional" waves rather than allowing only for "transverse" waves. At the present time I am still seeking to find a good "input relation" for matter as the source of gravitation (analogous to the relation found by Einstein and Hilbert for the 2nd order tensor equation of standard GR). The vacuum equation can be described as having (on a LHS side that is equated to zero) a fourth order term formed by the covariant d'Alembertian operating on the G-tensor of Einstein plus an additive portion of second order (as to the differentiation) formed by quadratic combinations of curvature tensor elements. The precise additive portion or set of terms is defined by the condition that the total LHS is so structured so as to be formally divergence free (like the G-tensor is intrinsically divergence free). The plan is to put into this directory, ultimately, files of graphic type including the tensor equations in handwritten form.
Completed infinities, called "alephs" are distributive in nature, similar to the way that a set of "red" objects has the distributive property of redness[qualia]. Properties, or "attributes" like red are numbers in the sense that they interact algebraically according to the laws of Boolean algebra. Take one object away from the set of red objects and the distributive number "red" still describes the set. The distributive identity[attribute] "natural number" or "real number" describes an entire collection of individual objects.
The alephs can be set into a one to one correspondence with a proper subset of of themselves. The "infinite" Cantorian alephs are really distributive[qualia].
Yet, if we have a finite set of 7 objects, the cardinal number 7 does not really distribute over its individual subsets. Take anything away from the set and the number 7 ceases to describe it[wave function collapse-condensation into specific localization].
Symmetry is analogous to a generalized form of self evident truth, and it is a distributive attribute via the laws of nature, being distributed over the entire system called universe. A stratification of Cantorian alephs with varying degrees of complexity. Less complexity = greater symmetry = higher infinity-alephs. So the highest aleph, the "absolute-infinity" distributes over the entire set called Universe and gives it "identity".
The highest symmetry is a distributive mathematical identity[also a total unknown but possibly analogous to a state of "nothingness"]. This fact is reflected in part, by the conservation laws.
So an unbound-infinite-potentia and a constrained-finite-bound-actuality, are somehow different yet the same. The difference and sameness relation is a duality. Freedom(higher symmetry) and constraint-complexity-organizational structure(lesser symmetry) form a relation that can be described by an invariance principle.
On a flat Euclidean surface, the three angles of a triangle sum to 180 degrees. On the curved surface of a sphere, the three angles add up to more than 180 degrees. On the hyperbolic surface of a saddle they sum to less than 180 degrees. The three types of surface are not equivalent.
There is a rotational invariance for a triangle, that seems to hold for the three types of surface though.
ABC = BCA = CAB
CBA = BAC = ACB
[ abstract representation]--->[semantic mapping]--->[represented system]
An abstract representation is exactly that, "abstract". It is not a space, or time, but is instead a product of consciousness, or a mental construct. Topologically it is equivalent to a "point". The abstract description contains the concrete topology. Likewise, the concrete contains the abstract.
A duality.
A point contains an infinite expanse of space and time?
Could it be, that the "absolute" infinity, is actually a dimensionless point? Or more correctly, an "infinitesimal"?
Universe? = Zero?
On one level of stratification, two photons are separate. On another level, of stratification, the photons have zero separation.
Instantaneous communication between two objects, separated by a distance interval, is equivalent to zero separation[zero boundary] between the two objects.
According to the book "Gravitation", chapter 15, geometry of spacetime gives instructions to matter telling matter to follow the straightest path, which is a geodesic. Matter in turn, tells spacetime geometry how to curve in such a way, as to guarantee the conservation of momentum and energy. The Einstein tensor[geometric feature-description] is also conserved in this relationship between matter and the spacetime geometry. Eli Cartan's "boundary of a boundary equals zero."
A point can be defined as an "infinitesimal". The Topological spaces are defined as being diffeomorphism invariant. Intersecting cotangent bundles[manifolds] are the set of all possible configurations of a system, i.e. they describe the phase space of the system.
Waves are then abstract distributions and particles are convergent "concrete" localizations.
Quantum mechanics leads us to the realization that all matter-energy can be explained in terms of "waves". In a confined region(i.e. a closed universe or a black hole) the waves exists as STANDING WAVES In a closed system, the entropy never decreases.
The analogy with black holes is an interesting one but if there is nothing outside the universe, then it cannot be radiating energy outside itself as black holes are explained to be. So the amount of information i.e. "quantum states" in the universe is increasing. We see it as entropy, but to an information processor with huge computational capabilities, it is compressible information.
Quantum field theory calculations where imaginary time is periodic, with period 1/T are equivalent to statistical mechanics calculations where the temperature is T. The periodic waveforms that are opposed yet "in phase" would be at standing wave resonance, giving the action.
Periodicity is a symmetry. Rotate into the complex plane and we have
real numbers on the horizonal axis and imaginary numbers on the
vertical axis. So a periodic function could exist with periodicity
along both the imaginary AND the real axis. Such functions would have
amazing symmetries. Functions that remain unchanged, when the complex
variable "z" is changed.
f(z)---->f(az+b/cz+d)
Where the elements a,b,c,d, are arranged as a matrix, forming an
algebraic group. An infinite number of possible variations that
commute with each other as the function f, is invariant under group
transformations. These functions are known as "automorphic forms".
Topologically speaking, the wormhole transformations must be
invariant with regards to time travel. In other words, by traveling
backwards in time, we "complete" the future, and no paradoxes are
created.
So when spacetime tears and a wormhole is created, it must obey
certain transformative rules, which probably appear to be
discontinuities from a "3-D" perspective, but really, these
transformations are continuous!
So the number of holes[genus] on the surface of space, determine
whether there exist an infinite, or finite, number of solutions to
the universal equations?
