Speculations on Cosmology
My continued interest in cosmology left me with the impression, that today's
'Standard Cosmology' is able to produce numerical results of astonishing
accuracy when compared with experimental findings. However, a fundamental
understanding appears to be lacking. In this situation I started to think
about the hypothesis that matter and antimatter might repel each other
(MAR), an attractive idea that has continued to flare up in the
literature almost since the discovery of antimatter by Paul Dirac (1928).
Today the Astrophysics community has banned this idea on the grounds
of Einstein's theory General Relativity (GR), and it is hardly ever
mentioned in modern textbooks any more.
This is astonishing considering the fact that GR was presented in 1915,
more than a dozen years before the advent of antimatter.
A similar relation holds true for Friedmann's models (1922)
which are the basis of today's 'Standard Model' of the Cosmos.
In addition they violate nature's probably most fundamental CPT symmetry.
This symmetry continues to be tested carefully which no unique consensus
as of today.
However, the Astropysics community seems to be more inclined to wait
for the discovery of such a violation than to allow putting to question
whether GR is able to handle antimatter correctly.
Many of the difficulties in a fundamental understanding of features of
the 'Standard Model' would conceivably disappear if we went back to
this old idea, such that I started to ask the heretical question,
whether there might not be a generalization or modification of GR
that was compatible with MAR.
There is a vast literature on Cosmology of which I only mention the
very concise and well readable books by
Andrew Liddle in which the basic questions are clearly exposed.
In the following I list a chronologically ordered sequence of short essays
on the topic, which have to be considered as reports of work in progress.
They are purposely left unchanged despite of the fact that they
occasionally contain statements that turned out to be incorrect later on.
Of course I am eagerly awaiting the results of the
at Cern which try to measure the deflection of antihydrogen in the
gravitational field of the earth.
- Evidence for Matter-Antimatter
Repulsion, a list of the most conspicuous problems that would find a
straightforward explanation with MAR.
- Bipolar Gravity, a first step towards
a modification of GR. These are purely static considerations.
- Lattice Model of the Universe, a
regular model which exemplifies that MAR generates a contribution to the
dark matter problem. However, the effect was grossly overestimated at

- Physics with Negative Masses
(http://viXra.org/abs/1303.0100) is a proposal to have negative gravitational
masses in physics as the consequence of the requirement that the
time-translation operator must have an unbounded spectrum. This route was
taken after it became clear that General Relativity is unable to accommodate
negative masses, since positive- and negative-curvature situations can never
- "Black Hole"-type objects
(http://viXra.org/abs/1311.0120) obtain a new
aspect in negative-mass Physics. They just represent a further level in
the sequence of late-stage states of stars, after the various dwarf types
and the neutron stars. Their expected high temperatures could lead to
antimatter generation, which may show up in emitted slow positrons and
electrons, giving rise to the galactic 511keV gamma-ray emission.
Furthermore, they may provide a simple explanation for Black-Hole jets.
- A Remark on Relativistic Quantum Mechanics
(http://viXra.org/abs/1407.0124) in which it is shown, that negative
masses are a consequence of the two-valuedness of the representations
of the Lorentz-group in Hilbert space. This elaborates on an earlier
statement that the worrying negative-energy solutions of the Dirac
equation are actually negative-mass solutions.
- What's Wrong with General Relativity?
(http://viXra.org/abs/1502.0067) A simple argument is presented, which
questions the consistency and, hence, validity of the theory of
General Relativity. This theory allows exclusively for non-negative masses
and so is the main obstacle to accepting any proposal of a
gravitation-theory with negative masses.
- Static Fields as Mass-Currents and Mercury's perihelion shift
(http://viXra.org/abs/1505.0078) The quantum-field nature of static classical
fields is explored. They appear as stationary mass-flows and, thus, should exhibit
retardation effects. This aspect revalidates an early calculation of
Mercury's perihelion shift.
- What's Wrong with General Relativity? (2)
(http://viXra.org/abs/1506.0038) Arguments are advanced that question whether
dynamic corrections (retardation effects) will not substantially modify the
result of General Relativity for the perihelion shift of Mercury and, thus,
destroy the good agreement with the experiment.
- Lattice model of a MAR-Cosmos.
The model is defined on a 3-dimensional periodic lattice and illustrates
the separation of matter and antimatter.
The initial state is a randomly-distributed density of both species on the
lattice sites, without any intended implication for the actual Cosmos!
An illustration is given by the following two videos:
Dotted representation, in which matter and
antimatter are represented by yellow and cyan dots (in either assignment).
A frame in white shows the unit cell of the model.
Contours in stereo, where contours are shown
which contain 50% of the total mass of matter and antimatter. For a stereo
impression the left-hand picture has to be watched with the right-hand eye
and vice versa.

of representations of the Lorentz Group.

(http://viXra.org/abs/1710.0252). This short note questions whether the
observed gavitational waves can be attributed unambiguously to the merger
of black holes.
