This special issue on `Fundamental Physics: Contemporary Thinking' includes papers by
Múnera, Mitskievich, Zachary and Gill, Mahato, Cervantes, Sachs, Stepanyantz,
Silagadze, Khlopov and Enders.
The Múnera paper advocates the absolute space concept. His basis is the
Miller-like interferometer experiments, which have been repeated recently. Obviously, they contradict
the Poincaré hypothesis that "the translational motion of earth could not be detected by
experiments carried out in our terrestrial laboratory." Another good point of his article is his analysis of
the historical concepts and bibliography. Apparently, he tries to
justify the use of a new method of measuring velocity without a reference object.
Two of Mitskievich's papers deal with higher dimensions and various
generalizations of equivalence principle and 4-vector potentials. However,
we would like to draw the readers' attention to an interesting paper on relations between Galileo and
Lorentz transformations (cf. also [1]).
Lectures of W Zachary and T Gill have been presented originally at the
Merida Workshop of 2006. "A modification of the conventional Maxwell theory is
constructed by replacing the observer time by the proper time of the source"that is their
main idea. This is related to the previous works of Horwitz and Piron and Fanchi [2].
"Among other results, it is shown that the group veclocity of electromagnetic waves
has different values in two inertial frames that are in uniform relative motion." It
seems that this is related to the reinterpretation of relativistic mass. They believe
that "both Einstein and Ritz were correct (corresponding to the choice of
different conventions)." Next, "...except for a constant scale change, the inhomogeneous
proper-time group has the same Lie algebra as the Poincaré group." Some other
unusual statements (for instance, concerning the experiments of Pound and
Snider [3]) have been made in these lectures.
Mahato again states that "torsion is uniformly nonzero everywhere", (see ref. [4]).
He considers `multiplicative torsion'. His article "has been prepared to study the
possibility of obtaining a conserved axial current following the results obtained in [4b]". Moreover,
he intends to explain the dark matter/energy problems by introducing scalar fields.
D Cervantes studies discrete symmetries and Galilean invariance of the
Schrödinger-Pauli equations resulting from the limiting procedure of the Dirac equation.
M Sachs tries to construct the unified field theory. The direct product of two
4-spinors would give the spin-2 under Sachs' definitions only. The basis for these definitions should
be explained in detail. It is well known from Bargmann and Wigner that the multispinor of
the second rank gives spins 0 and 1,( ref. [5]). A more detailed discussion on magnetic
monopoles could also be interesting, because a few other authors report that magnetic
monopoles have already been found in experiment, (e. g., ref. [6]).
Stepanyantz from Moscow State University contributed to this issue. We hope
that specialists would enjoy his results.
Silagadze argues that the introduction of the mirror dark matter [7] "has
a potential to reconcile ... seemingly contradictory observational facts." In fact,
the author suggests that "left-right symmetry of the world could be rescued by
duplicating the non-symmetric part of our left-handed universe in the mirror."
The Khlopov paper is on the intersection between particle physics and cosmology.
As far as we remember, the technicolor model has been proposed in the 1980s. But, what
is important in the Khlopov paper, in our opinion, is that the dark matter is again
associated with some kind of particles (WIMP?).
Enders' paper, which concludes the issue, is rather a historical one.
In fact, in preparing this special issue, we have
tried to inflame discussions and pay attention to some old
things, that is, to do the same as in the previous books of the
Guest Editor [ref. 8, 9, 10] and in several special issues
of other journals. We hope that it will be possible to
advance science in this way.
