We discuss the results of modern Mössbauer experiments in a rotating system, which show the presence of an extra energy shift between the emitted and absorbed resonant radiation in addition to the relativistic energy shift of the resonant lines due to the time dilation effect in the co-rotating source and absorber with different radial coordinates. We analyse the available attempts to explain the origin of the extra energy shift, which include some extensions of special theory of relativity with hypothesis about the existence of limited acceleration in nature, with hypothesis about a so-called «time-dependent Doppler effect», as well as in the framework of the general theory of relativity under re-analysis of the metric effects in the rotating system, which is focused to the problem of correct synchronisation of clocks in a rotating system with a laboratory clock. We show that all such attempts remain unsuccessful until the moment, and we indicate possible ways of solving this problem, which should combine metric effects in rotating systems with quantum mechanical description of resonant nuclei confined in crystal cells.

AbstractAn extra energy shift between emitted and received radiation on a rotating disc – next to the conventionally recognised second-order Doppler shift – has been revealed in a series of recent Mössbauer experiments, where a radioactive source is fixed at the centre and an absorber is attached to the rim of the rotating disc. This disclosure gives indication to a possible violation of the “clock hypothesis” by Einstein: i.e. the independence of the rate of a clock on its acceleration. At the moment, there seem to be two plausible interpretations of this result: (i) the deviation of the geometry of the rotating disc from that predicted by the general theory of relativity (GTR), or (ii) the existence of a specific maximal acceleration in nature, when transformation between two accelerated frames differs from the corresponding transformation of the relativity theory. We take a closer look at both ways leading to the violation of the clock hypothesis; particularly, by analysing the outcomes of recent experiments in rotating systems and by suggesting a new Mössbauer rotor experiment to determine the most feasible mechanism for testing the dependence of the rate of a clock on its acceleration.

Momentum Relation

The Dirac equation consistent with the principles of quantum mechanics and the special theory of relativity, introduces a set of matrices combined with the wave function of a particle in motion to give rise to the relativistic energy-momentum relation. In this paper a new hypothesis, the wave function of a particle in motion is associated with a pair of complementary waves is proposed. This hypothesis gives rise to the same relativistic energy-momentum relation and achieves results identical to those of Dirac. Additionally, both the energy-time and momentum-position uncertainty relations are derived from the complementary wave interpretation. How the complementary wave interpretation of the Dirac equation is related to the time-arrow and the four-vectors are also presented.

The non-inertiality of the rotating system of Faraday's unipolar generator forces us to address this problem using the principles of the general theory of relativity. The purpose of this study is to compare the theoretical quantitative estimates of induced electromotive force with the experimental results obtained from the corresponding measurements. The theoretical elaboration of this issue proves that the differences between the results of the general theory in relation to those of the special theory of relativity are some negligible terms, which are due to the non-inertiality of the rotating reference system. This result enables us to consider the theoretical estimates based on special and general relativity as equivalent, with quite satisfactory accuracy. Therefore, a very serious issue of inconsistency between the theory of relativity and the measurements of induced electromotive force emerges, since as already shown in the existing literature, this inconsistency, from the point of view of the special theory of relativity, is already proven.

The prospect of a machine in which one could be transported through time is no longer mere fantasy, having become in this century the subject of serious scientific and philosophical debate. From Einstein’s special theory of relativity we have learned that a form of time travel into the future may be accomplished by moving quickly, and therefore ageing slowly (exploiting the time dilation effect). And in 1949 Kurt Gödel announced his discovery of (general relativistic) spacetimes whose global curvature allows voyages into the past as well. Since then the study of time travel has had three main strands. First, there has been research by theoretical physicists into the character and plausibility of structures, beyond those found by Gödel, that could engender closed timelike lines and closed causal chains. These phenomena include rotating universes, black holes, traversable wormholes and infinite cosmic strings (Earman 1995). Second, there has been concern with the semantic issue of whether the terms ‘cause’, ‘time’ and ‘travel’ are applicable, strictly speaking, to such bizarre models, given how different they are from the contexts in which those terms are normally employed (Yourgrau 1993). However, one may be sceptical about the significance of this issue, since the questions of primary interest – focused on the nature and reality of the Gödel-style models – seem independent of whether their description requires a shift in the meanings of those words. And, third, there has been considerable discussion within both physics and philosophy of various alleged paradoxes of time travel, and of their power to preclude the spacetime models in which time travel could occur.

We present the results of a novel Mössbauer experiment in a rotating system, implemented recently at Istanbul University, which yields the coefficient k = 0.69 ± 0.02 within the frame of the expression for the relative energy shift between emission and absorption lines ΔE/E = ku2/c2. This result turned out to be in quantitative agreement with an experiment achieved earlier on the subject matter (Kholmetskii et al. Phys. Scr. 79, 065007 (2009)), and once again strongly pointed to the inequality k > 0.5, revealed originally in (Kholmetskii et al. Phys. Scr. 77, 035302 (2008)) via the re-analysis of Kündig’s experiment (Kündig, Phys. Rev. 129, 2371 (1963)). A possible explanation of the deviation of the coefficient k from the relativistic prediction k = 0.5 is discussed.
