This monograph expounds on general Yang-Mills symmetry, a new
symmetry based on arbitrary vector gauge functions and Hamilton's
characteristic phase functions in the gauge transformations of
Abelian and non-Abelian groups. General Yang-Mills symmetry
includes the conventional gauge symmetries as special cases and is
useful for describing phenomena at scales ranging from the
super-macroscopic such as dark matter, to the ultra-microscopic
such as the quantum 3-body problem of baryons. Moreover, this
symmetry supports the Broader Particle-Cosmology framework based on
particle physics and quantum Yang-Mills gravity in flat space-time,
which can explain why the gravitational force is always attractive.
This volume also discusses how CPT invariance in particle physics
suggests a 'Big Jets' model for the birth of the universe,
proposing one explanation for the dearth of anti-matter in our
universe. Finally, we discuss a simplified quantum shell model for
N baryons with a quark Hamiltonian and a Sonine-Laguerre equation
that gives reasonable eigenvalues for the energies of the 29 N
baryons.
This book shows how one can combine Yang-Mills gauge symmetry and
effective Einstein-Grossmann metric tensors to tackle physical
problems at microscopic, macroscopic and super-macroscopic length
scales. In particular, the combination of gauge symmetry and an
effective metric tensor provides a framework for and leads to an
alternative dynamics of cosmic expansion based on quantum
Yang-Mills gravity at the super-macroscopic limit. Together with
the cosmological principle, one can investigate and derive
expanding scale factors, the age of the universe, the cosmic
redshift, and the Hubble recession velocity. Furthermore, this
framework leads to a possible explanation for the late-time
accelerated cosmic expansion due to baryon masses and charges. All
these discussions are based on the operationally defined space and
time coordinates of inertial frames. Finally, this book expounds on
the intimate relationship between space-time translation gauge
symmetry and the beautiful ideas of the Lie derivative and Pauli's
variation. One interesting application of the Lie derivative is to
formulate a gravitational theory with an external space-time gauge
group, which leads to Yang-Mills gravity.
The ICGAC-12 aimed to serve as a common platform around the
Asia-Pacific region for the exchange and communication among all
researchers in the fields of gravitation, astrophysics and
cosmology. The scope covered in the conference includes dark
matter, dark energy, experimental study of gravity, black holes,
quantum Yang-Mills gravity, GR extension, variation of constants,
fundamental physics space projects, relativistic astrophysics,
white dwarfs, neutron stars, and gamma ray bursts.
Yang-Mills gravity is a new theory, consistent with experiments,
that brings gravity back to the arena of gauge field theory and
quantum mechanics in flat space-time. It provides solutions to
long-standing difficulties in physics, such as the incompatibility
between Einstein's principle of general coordinate invariance and
modern schemes for a quantum mechanical description of nature, and
Noether's 'Theorem II' which showed that the principle of general
coordinate invariance in general relativity leads to the failure of
the law of conservation of energy. Yang-Mills gravity in flat
space-time appears to be more physically coherent than conventional
gravity in curved space-time. The problems of quantization of the
gravitational field, the operational meaning of space-time
coordinates and momenta, and the conservation of energy-momentum
are all resolved in Yang-Mills gravity.The aim of this book is to
provide a treatment of quantum Yang-Mills gravity, with an emphasis
on the ideas and evidence that the gravitational field is the
manifestation of space-time translational symmetry in flat
space-time, and that there exists a fundamental space-time symmetry
framework that can encompass all of physics, including gravity, for
all inertial and non-inertial frames of reference.
A Broader View of Relativity shows that there is still new life in
old physics. The book examines the historical context and
theoretical underpinnings of Einstein's theory of special
relativity and describes Broad Relativity, a generalized theory of
coordinate transformations between inertial reference frames that
includes Einstein's special relativity as a special case. It shows
how the principle of relativity is compatible with multiple
concepts of physical time and how these different procedures for
clock synchronization can be useful for thinking about different
physical problems, including many-body systems and the development
of a Lorentz-invariant thermodynamics. Broad relativity also
provides new answers to old questions such as the necessity of
postulating the constancy of the speed of light and the viability
of Reichenbach's general concept of time. The book also draws on
the idea of limiting-four-dimensional symmetry to describe
coordinate transformations and the physics of particles and fields
in non-inertial frames, particularly those with constant linear
accelerations. This new edition expands the discussion on the role
that human conventions and unit systems have played in the
historical development of relativity theories and includes new
results on the implications of broad relativity for clarifying the
status of constants that are truly fundamental and inherent
properties of our universe.
