Interfacing Friedman and string cosmologies
Compactification and symmetry breaking events in theories of heterotic
superstrings implicitly indicate five inflation events. Scales of 10^{9} ly and
larger are modeled in terms of these events. The proposed model accounts
qualitatively for recent observations (of galactic clusters that lie on
"thin,.. semi-spherical shells") and motivates a calculation that accounts
(approximately) for the observed number of galaxies.Comment: 4 pages, no figure
Supergravitational Production of "Flavor and Color"
A conventional graviton vertex operator is generated from the gauging of
global supersymmetry. If the outgoing gravitino is replaced by a fermion-boson
pair of like helicity, and if a new principle of equivalence associates
supergravity with the introduction of color, then every quark flavor can be
described as a gravitationally excited lepton. In this context, A SUSY SU(5)can
be constructed exclusively of leptons and their scaler superpartners (or of
quarks and their superpartners). This SUSY GUT flavor symmetry, which is
preserved by the proposed supergravity interactions, accounts for three
fermionic generations and predicts a new quark--aleft-handed (non-strange)
version of the strange quark.Comment: 9 pages, 5 figure
An Asymmetry in the Maxwell Equations
A term in the Maxwell-Ampere law describes a linear displacement current that
is symmetrically enclosed by the curl of a magnetic field. In this context
symmetry calls for a term in the Faraday-Lenz law, which in the absence of a
conducting coil would describe a loop of displacement current about a linear
increment of magnetic flux. This term, introduced to satisfy symmetry, predicts
a physical phenomenon that has recently been observed.Comment: 3 pages, no figure
SUGRA interactions at thresholds of asymptotic freedom
A generic heterotic string theory is uniquely reduced to the standard model
in terms of a geometry that transcends compactification. This device also
extends the standard model to embrace three generations of fermions, including
a left-handed strange quark that is devoid of strangeness and three
right-handed neutrinos. Finally the proposed hypothesis indicates
supergravitationally mediated quark-lepton transitions that preserve baryon
structure, departing from the SUSY GUT tradition that predicts proton decay.Comment: 7 pages, no figure
Quantization as a Consequence of Symmetry
It is argued that the Heisenberg relation on 4-spacetime is a necessary
condition for the local gauge invariance of a classical wave in the
5-dimensional Kaluza-Klein theory.Comment: Six pages no figure
SUGRA interactions within flavor triplets
A specific new quark permits that flavor generations constitute a
representation of the 3-dimensional SU(3) symmetry that characterizes the Z(3)
orbifold. In this context, color and supergravity bind triplets and 4-tuplets
into composite fields of spin 3/2 and spin 2; and the symmetry E(8) that
characterizes (the observable sector of) 10-spacetime is interpreted as having
reduced to SU(5)XSU(3), where SU(3) refers to the 3-dimensional symmetry
described above and SU(5) consists of colors and of isotopic spin classes that
are devoid of color and hypercharge. In this context, supergravity interactions
occur to color bound quarks that are experiencing asymptotic freedom within
triplets. Quark-lepton transitions are produced, but quickly reverse,
preserving the triplets. The symmetry consisting of six quark classes and six
lepton classes is also maintained because the predicted quark is an anomalous,
left-handed version of the strange quark.Comment: 5 pages, 2 figure
A Realistic Superunification
It is argued that every quark flavor can be described as a lepton that has
been excited by the absorption of a supernatural field, which is defined. In
this context, a minimal irriducible representation of SUSY SU(5) is constructed
exclusively of the chiral modes that correspond to three generations of leptons
(or quarks) and their scaler superpartners. The proposed model predicts a new
quark; a left-handed (non-strange) version of the strange quark.Comment: 7 Pages, 8 Figures. Corrections to figures 7 and 8 and to equations

A differential geometric context in which quantization is a necessary condition for gauge invariance
It has recently been argued that quantization can be established within
classical theory as a consequence of lost information. In this view, classical
mechanics is regarded as a union of quantum mechanics and what are called
'hidden variables'. Hidden variable theories were first considered some years
ago and abandoned because they did not produce new physics. They have now been
revived however, because they appear to provide a logically sound means of
relating classical and quantum theories. It is argued here that the Heisenberg
uncertainty relations constitute a necessary condition for gauge invariance in
the 5-dimensional Kaluza-Klein theory, where the fifth dimension of 5-spacetime
is hidden as a 5-dimensional theory of general relativity is projected onto
4-spacetime.Comment: 7 pages, no figure
Quantization as a Necessary Condition for Gauge Invariance
Symmetry and quantization are the two major enterprises of theoretical
physics; but some argue that quantization can be derived as a necessary
condition for symmetry. It is argued here that the Heisenberg uncertainty
principle is a necessary condition for gauge invariance in the 5-dimensional
Kaluza-Klein theory.Comment: 8 pages, no figure
Membrane paradigm of the static black bottle
In the membrane paradigm of black holes, it is usually assumed that the
normal vector of the stretched horizon has a vanishing acceleration. This
assumption breaks down for black bottles, a class of solutions discovered
recently in the asymptotically anti-de Sitter spacetime. In this paper, the
membrane paradigm is generalized to the stretched horizon with a nonvanishing
acceleration of normal vector, and then it is applied to the static black
bottle. In this example, the membrane stress tensor and the fluid quantities
are similar to those of black holes, while the fluid continuity equation and
the Navier-Stokes equation are well satisfied in the near-horizon limit.Comment: 9 page
