Space-time euclidean

The symmetry between curvature and matter is the most important result of Einstein s gravitational field equations. Both of these tensors vanish in empty euclidean space and the symmetry implies that whereas the presence of matter causes space to curve, curvature of space generates matter. This reciprocity has the important consequence that, because the stress tensor never vanishes in the real world, a non-vanishing curvature tensor must exist everywhere. The simplifying assumption of effective euclidean space-time therefore is a delusion and the simplification it effects is outweighed by the contradiction with reality. Flat space, by definition, is void. [Pg.21]

Recall the reciprocity between matter and curvature, implied by the theory of general relativity, to argue that the high-pressure condition at Z/N = 1 corresponds to extreme curvature of space-time caused by massive objects such as quasars, and the like. The argument implies that the Schrodinger solution is valid in empty, flat euclidean space-time, that Z/N = r corresponds to the real world, Z/N = 1 occurs in massive galactic objects where elemental synthesis happens, and Z/N > 1 implies infinite curvature at a space-time singularity. [Pg.136]

Note that interpretations of the time-reversal experiments are only valid in strictly euclidean space-time. This condition is rarely emphasized by authors who state that all laws of physics are time-reversible, except for the law of entropy. Fact is that entropy is the only macroscopic state function which is routinely observed to be irreversible. One common explanation is to hint that entropy is an emergent property of macro systems and hence undefined for microsystems. Even so, the mystery of the microscopic origin of entropy remains. A plausible explanation may be provided if the assumed euclidean geometry of space-time is recognized as an approximate symmetry as demanded by general relativity. [Pg.12]

Not only the laws of Nature but also all major scientific theories are statements of observed symmetries. The theories of special and general relativity, commonly presented as deep philosophical constructs can, for instance, be formulated as representations of assumed symmetries of space-time. Special relativity is the recognition that three-dimensional invariances are inadequate to describe the electromagnetic field, that only becomes consistent with the laws of mechanics in terms of four-dimensional space-time. The minimum requirement is euclidean space-time as represented by the symmetry group known as Lorentz transformation. [Pg.25]

It was Schrodinger s intention to associate Zitterbewegung with electron spin, but such an assumption would serve simply to clarify one mystery in terms of another. Instead, one could try first to understand the nature of Zitterbewegung within the region identified as the electron. The only substance available to support the periodic motion is space itself and there seems to be two possibilities either space consists of continuous stuff or of compacted particles. Winterberg [68] explored the latter possibility. Wave motion in a continuous aether is probably easier to visualize and needs fewer assumptions. The only postulate is that ponderable matter and its properties represent special configurations of space. Hence flat Euclidean space (-time) in dimensions of any number, is featureless and empty. [Pg.95]

General relativity goes no further than this. The extent of curvature or the topology of space-time depends on additional observations and criteria. Assumptions to simplify the mathematics, but not supported by testable data, must inevitably produce spurios results. Examples of such simplifications include the assumption of universal time or Euclidean space-time. Einstein s thought experiment which established the non-Euclidean nature of space-time also predicts the nature of the curvature as positive, which excludes hyperbolic space. [Pg.302]

Relativity theory has equally dramatic implications on the nature of the vacuum, which is shown not to be a void, but a medium that supports wave motion and carries electromagnetic fields. A new perspective on the nature of the vacuum is provided by the principle of equivalence. Space-time curvature can be described mathematically by a Riemann tensor, which the principle implies, should balance the gravitational field, which is sourced in the distribution of matter. This reciprocity indicates that Euclidean space-time is free of matter, which only emerges when curvature sets in. This is interpreted to mean that the homogeneous wave field of Euclidean vacuum generates matter when curved. Like a flat sheet that develops wrinkles when wrapped arormd a curved surface, the wave field generates non-dispersive persistent wave packets in the curved vacuum. [Pg.302]

Reaching beyond the solar system becomes more problematical. Extrapolating into the extension of familiar Euclidean space-time we are soon overwhelmed by billions of solar systems in the Galaxy, which we call the Milky... [Pg.310]

The mass variable is a strictly empirical assumption that only acquires meaning in non-Euclidean space-time on distortion of the Euclidean wave field defined by Eq. (2). The space-like Eq. (5), known as Schrodinger s time-independent equation, is not Lorentz invariant. It is satisfied by a non-local wave function which, in curved space, generates time-like matter-wave packets, characterized in terms of quantized energy and three-dimensional orbital angular momentum. The four-dimensional aspect of rotation, known as spin, is lost in the process and added on by assumption. For macroscopic systems, the wave-mechanical quantum condition ho) = E — V is replaced by Newtonian particle mechanics, in which E = mv +V. This condition, in turn, breaks down as v c. [Pg.30]

The instanton theory was invented in the field theory by introducing imaginary time to Minkowski space-time. The instanton is the classical object in the Euclidean space-time that gives a finite action. The instanton is also called pseudo-particle. Here the theory is explained by following Coleman [2]. See also References [17,39,43,46]. [Pg.16]

To set up the problem and in order to appreciate more fully the difficulty in quantifying complexity, consider figure 12.1. The figure shows three patterns (a) an area of a regular two-dimensional Euclidean lattice, (b) a space-time view of the evolution of the nearest-neighbor one-dimensional cellular automata rule RllO, starting from a random initial state,f and (c) a completely random collection of dots. [Pg.613]

Jourjine [jour85] generalizes Euclidean lattice field theory on a d-dimensional lattice to a cell complex. He uses homology theory to replace points by cells of various dimensions and fields by functions on cells, the cochains, in hopes of developing a formalism that treats space-time as a dynamical variable and describes the change in the dimension of space-time as a phase transition (see figure 12.19). [Pg.691]

The final objective is an equation that relates a geometrical object representing the curvature of space-time to a geometrical object representing the source of the gravitational field. The condition that all affine connections must vanish at a euclidean point, defines a tensor [41]... [Pg.163]

In the real world the stress tensor never vanishes and so requires a nonvanishing curvature tensor under all circumstances. Alternatively, the concept of mass is strictly undefined in flat Minkowski space-time. Any mass point in Minkowski space disperses spontaneously, which means that it has a space-like rather than a time-like world line. In perfect analogy a mass point can be viewed as a local distortion of space-time. In euclidean space it can be smoothed away without leaving any trace, but not on a curved manifold. Mass generation therefore resembles distortion of a euclidean cover when spread across a non-euclidean surface. A given degree of curvature then corresponds to creation of a constant quantity of matter, or a constant measure of misfit between cover and surface, that cannot be smoothed away. Associated with the misfit (mass) a strain field appears in the curved surface. [Pg.164]

Interpreted, as it is, within the standard model, Higgs theory has little meaning in the real world, failing, as it does to relate the broken symmetry of the field to the chirality of space, time and matter. Only vindication of the conjecture is expected to be the heralded observation of the field bosons at stupendous temperatures in monstrous particle accelerators of the future. However, the mathematical model, without cosmological baggage, identifies important structural characteristics of any material universe. The most obvious stipulation is to confirm that inertial matter cannot survive in high-symmetry euclidean space. [Pg.175]

There is no evidence that Minkowski space is flat on the large scale. The assumption of euclidean Minkowski space could therefore be, and probably is an illusion, like the flat earth. In fact, there is compelling evidence from observed spectroscopic red shifts that space is curved over galactic distances. These red shifts are proportional to distances from the source, precisely as required by a curved space-time[52j. An alternative explanation, in terms of an expanding-universe model that ascribes the red shifts to a Doppler... [Pg.175]

In figure 3 the dependence pA(t) in log-log coordinates, corresponding to the relationship (4), for the reesterification reaction in TBT presence is adduced. As can be seen, this dependence breaks down into two linear parts with different slopes. For the first part (/<90 min.) the slope is equal to -0,75, i.e., corresponded to the equation (6) for reaction proceeding in three-dimensional Euclidean space (d= 3). For the second part (/>90 min.) the slope is equal to 3, i.e., not corresponded to possible value of this exponent for recombination reaction or other analogous reactions, for which the value a is limited from above by the value 1,5 [2-4, 9], This means, that for the considered reesterification reaction times smaller of 90 min. it s necessary to identify as short times, i.e., on this temporal interval reactive particles concentration decay controls by local fluctuations of TBT distribution, and times equal or...

Other careful computer simulations [33] focused more attention on the two diffusion-controlled reactions A + B —> 0 and A + A — 0, on both fractal and Id lattices. In the case of the Euclidean space it was well demonstrated that achievement of the theoretical limit of a = 0.25 is a quite long-time... [Pg.353]

Let us assume the existence of a four-dimensional (4D) flat Euclidean space E = (u,x,y,z), where the time dimension u = vut behaves exactly the same as the three spatial dimensions [102, 104]. Further, let S be filled with a fluid of preons (=tiny particles of mass m and Planck length dimensions). These particles are in continual motion with speed "V = (vH, vx, vy, vz) = (v , V). No a priori limits are set on the speed vu of preons along the u -axis.8... [Pg.359]

The representation of the sampling by a unipolar, single-rotation-axis, U(l) sampler of a SU(2) continuous wave that is polarization/rotation-modulated is shown in Fig. 2, which shows the correspondence between the output space sphere and an Argand plane [28]. The Argand plane, S, is drawn in two dimensions, x and v, with z = 0, and for a set snapshot in time. A point on the Poincare sphere is represented as P(t,x,y,z), and as in this representation t = 1 (or one step in the future), specifically as P(l,x,y,z). The Poincare sphere is also identified as a 3-sphere, S 1, which is defined in Euclidean space as follows ... [Pg.713]

All solutions of Einstein s equations are conditioned by the need of some ad hoc assumption about the geometry of space-time. The only indisputably valid assumption is that space-time is of absolute non-euclidean geometry. It is interesting to note that chiral space-time, probably demanded by the existence of antimatter and other chiral forms of matter, rules out the possibility of affine geometry, the standard assumption of modern TGR [7]. [Pg.21]

In the previous section we analyzed the random walk of molecules in Euclidean space and found that their mean square displacement is proportional to time, (2.5). Interestingly, this important finding is not true when diffusion is studied in fractals and disordered media. The difference arises from the fact that the nearest-neighbor sites visited by the walker are equivalent in spaces with integer dimensions but are not equivalent in fractals and disordered media. In these media the mean correlations between different steps (UjUk) are not equal to zero, in contrast to what happens in Euclidean space cf. derivation of (2.6). In reality, the anisotropic structure of fractals and disordered media makes the value of each of the correlations u-jui structurally and temporally dependent. In other words, the value of each pair u-ju-i-- depends on where the walker is at the successive times j and k, and the Brownian path on a fractal may be a fractal of a fractal [9]. Since the correlations u.juk do not average out, the final important result is (UjUk) / 0, which is the underlying cause of anomalous diffusion. In reality, the mean square displacement does not increase linearly with time in anomalous diffusion and (2.5) is no longer exact. [Pg.26]

When Fickian diffusion in normal Euclidean space is justified, further verification can be obtained from the analysis of 60% of the release data using the power law in accord with the values of the exponent quoted in Table 4.1. Special attention is given below for the values of b in the range 0.75-1.0, which indicate a combined release mechanism. Simulated pseudodata were used to substantiate this argument assuming that the release obeys exclusively Fickian diffusion up to time t = 90 (arbitrary units), while for I, > 90 a Case II transport starts to operate too this scenario can be modeled using... [Pg.83]

Time reversal transformation, t - — t This is like space inversion and most likely space-time inversion is a single symmetry that reflects the local euclidean topology of space, observed as the conservation of matter. [Pg.5]

The concept of local distortions of space-time can be visualized in crude analogy with the impossibility of covering a curved surface with a flat sheet. It may seem to work at short range, but over an extended (closed) surface wrinkles appear in the cover and despite all efforts to smooth them away a fixed amount of misfit between surface and cover persists. Identifying space-time with a flat Euclidean cover then shows how any large-scale curvature must result in the creation of local distortions. As elementary particles of few types occur in Nature distortion of space is quantized, and like other quantum phenomena would therefore be conveniently described in wave formalism. [Pg.96]

An elegant but simple model of a five-dimensional universe has been proposed by Thierrin [224]. It is of particular interest as a convincing demonstration of how a curved four-dimensional manifold can be embedded in a Euclidean five-dimensional space-time in which the perceived anomalies such as coordinate contraction simply disappear. The novel proposal is that the constant speed of light that defines special relativity has a counterpart for all types of particle/wave entities, such that the constant speed for each type, in an appropriate inertial system, are given by the relationship...
