Smooth rims in Queen Alexandra Range (QUE) 99177: Fluid–chondrule interactions and clues on the geochemical conditions of the primordial fluid that altered CR carbonaceous chondrites

Queen Alexandra Range (QUE) 99177 is one of the least altered CR carbonaceous chondrite known, with mineralogical and isotopic characteristics that indicate a high level of pristinity. In this study, we have examined the so-called smooth rims that surround many type I chondrules in QUE 99177, using SEM, EPMA, and FIB-TEM techniques. We have characterized their constituent phases to unravel the precursor material(s) of smooth rims, assess their formation mechanisms, and constrain the conditions of the altering fluid. Smooth rims are the most common type of rims around type I chondrules and exclusively occur around chondrules with Silica-rich Igneous Rims (SIRs). Smooth rims consist of an Fe-rich, hydrous silicate material that is Si- and Fe-rich, with minor Mg, Al, Ca, and Mn, and gives low analytical totals measured by EPMA. TEM observations reveal that the Fe-rich silicate phase is an amorphous gel that contains unaltered crystalline phases and igneous glass. Crystalline phases consist of igneous, unaltered, zoned pyroxenes with compositions consistent with pyroxenes in SIRs, as well as albite and chromite. The amorphous gel preserves previous crystal outlines with morphologies consistent with silica (cristobalite) grains in SIRs and has a composition identical to pseudomorphic silica replacements in SIRs. Based on these observations, we conclude that smooth rims derive from low-temperature aqueous alteration of silica in SIRs by an Fe-rich fluid. We suggest that the Fe was derived by leaching of amorphous silicates in the matrix, which reacted rapidly with melted water ice, although alteration of Fe,Ni metal blebs in SIRs could potentially be an additional source of Fe. Silica underwent dissolution and replacement whereas feldspar and glass remained unaltered because (1) the fluid was slightly alkaline, (2) cristobalite has a reaction rate much higher than quartz and feldspar, and (3) the alteration was very limited and fast, indicating that it was due solely to melting of accreted water ice and there was no introduction of additional fluid from external sources.

The Flat Galactic Rotation Curves from First Principles: A Novel Logarithmic Potential Originating in Laplace’s Equation

Abstract This note reports flat galactic rotation curves coinciding with observation and originating in Laplace’s classical field equation. Dark matter, identified with a primordial fluid populating the entire universe, is represented by the homogeneous Klein–Gordon equation (KGE). The key element is the novel solution for the KGE discovered by the leading author in 1994, expressed as a permanent background  -potential plus an entangled  -potential where time and distance appear as a ratio. The  -potential may be viewed as solution to a non-homogeneous Laplace equation, for which the general solution contains in addition to Newton’s 1/r potential a new logarithmic Zwicky potential overlooked thus far. The ensuing 1/r-Zwicky force predicts the observed flat galatic rotation curves exhibiting the observed limiting speed at long distance.

Negative Gravitational Mass: An Ideal Solution for Cosmology

This article provides a physical solution to cosmic inflation, the onset of the radiation epoch and the reheating epoch. It does not require dark energy thanks to a zero cosmological constant. Cosmological inflation is a mathematical solution considered necessary for the coherence of cosmological models. There are several versions of it, but there is currently no physical basis to explain it. We show that the existence of negative heavy masses (but always positive inert masses) makes it possible to explain it and also makes it possible to justify many other phenomena. Experiments are underway to test the hypothesis of negative heavy masses. The first results should be obtained within 1 or 2 years. In this solution, inflation occurs at the onset of the gravitational interaction much earlier than in the commonly accepted chronology. Gravitation gives rise to a negative pressure primordial fluid verifying the inflation conditions known as “slow roll”. It leads to regularity in matter density and temperature of the CMB. The structures of filaments, walls and large cosmic voids (and even superclusters) can be explained as a consequence of the influence of this matter of negative gravitational mass.

Neo-Cartesian unified fluid and field theory: from Klein-Gordon equation to de Broglie’s Lorentz invariant mechanics

A unified fluid and field theory containing all forces as special cases postulates that primordial fluid is formed by discrete, 3D-extended energy-like sagions obeying usual energy-momentum conservation laws. Contrary to Newtonian mechanics, mass and force are not primitive notions (hence, “Cartesian”), but the theory is atomistic (hence “neo”). Collective fluid behaviour obeys the homogeneous Klein-Gordon equation, or homogeneous 3D-wave equation, which besides usual harmonic periodic solutions has three families of quantized, Galilean-Lorentz isomorph, nonperiodic solutions discovered around 1995. Here, quantum mechanics is relativistic ab initio thus ensuring consistency with Einstein’s general theory of relativity, which is extended to include effects upon gravity of chemical and nuclear composition, as indeed observed by Eötvös (1890s), and Majorana (1919). Planck constant is identified with the bit of minimum angular momentum in sagion-sagion interactions, thus introducing quantum features at the root of classical mechanics. Acceleration produced by successive pushes of a small projectile (say, a sagion, disagion, trisagion, 4-sagion) leads to a curve resembling Einstein’s mass increase. This reinterprets one aspect of the restricted theory of relativity: rather than mass increase, Bertozzi experiment demonstrates inefficient transfer of linear momentum. The lower branch in our background universal acceleration curve is associated to static friction.

General relativity as a unified fluid and field theory

Einstein’s dream for a unified field theory of Nature is attained with a classical fluid theory founded on space, time and spin, rather than on Einstein’s spacetime. An invariant quantum theory for the primordial fluid obeys the homogeneous Klein-Gordon equation, which is the same three-dimensional classical wave equation (CWE) initially tried by Schrödinger to formulate quantum mechanics (QM), but abandoned by linear superposition considerations. Primordial fluid pervades universe, obeys energy and momentum conservation, and is formed by sagions: energy-like, discrete, extended Planck-size objects of finite size, carriers of linear momentum and spin, moving in absolute 3D-curved space with speed C along straightest path. We briefly describe our novel non-harmonic and inherently quantized solutions for CWE in spherical coordinates, discovered in 1995. Solutions include a steady-state background field (possibly related to the CMB, to non-locality, and to action-at-a-distance), quantized helices, and inherently quantized functions exhibiting stable dynamic equilibrium, and isomorphism under many transformations, including the classical Doppler case, and the relativistic Lorentz, Poincaré, and Einstein transformations. Isomorphism pre-empts ab initio a few interpretative issues regarding relativistic and classical transformations. Mathematical fields represent the realistic physical temporal evolution of the primordial fluid in curved 3D-space.

Geochemical constraints on the Hadean environment from mineral fingerprints of prokaryotes

The environmental conditions on the Earth before 4 billion years ago are highly uncertain, largely because of the lack of a substantial rock record from this period. During this time interval, known as the Hadean, the young planet transformed from an uninhabited world to the one capable of supporting, and inhabited by the first living cells. These cells formed in a fluid environment they could not at first control, with homeostatic mechanisms developing only later. It is therefore possible that present-day organisms retain some record of the primordial fluid in which the first cells formed. Here we present new data on the elemental compositions and mineral fingerprints of both Bacteria and Archaea, using these data to constrain the environment in which life formed. The cradle solution that produced this elemental signature was saturated in barite, sphene, chalcedony, apatite, and clay minerals. The presence of these minerals, as well as other chemical features, suggests that the cradle environment of life may have been a weathering fluid interacting with dry-land silicate rocks. The specific mineral assemblage provides evidence for a moderate Hadean climate with dry and wet seasons and a lower atmospheric abundance of CO2 than is present today.

Hydrodynamic theory of magnetic fields due to electron currents in a straight wire

In previous articles in this journal, the author presented hydrodynamic models of the electron as a sink and the positron as a source for the continuous flow of a primordial incompressible ideal fluid from sources to sinks in ordinary three-dimensional space generating the electrostatic field. The return flow from a sink to a source occurs through a wormhole tube (called an ether string) in four-dimensional space-time. It was assumed that the finite core of a primitive electron and the core of a primitive positron would be trapped at the boundary surface of the cylindrical core of a linear vortex in the fluid. The interaction between the flow component into the electron sink and the vortex field would wind the ether string linking the electron and positron cores into a helix (called an ether spring) located at the surface of the vortex core. Loosely bound electrons in metal atoms can migrate through the lattice of a metal crystal while still remaining linked by an ether spring to the positron in the proton in the original atomic nucleus. When a piece of metal is broken into two or more parts, some of the free electrons in each part may remain linked to protons in another part. These electrons are referred to as externally linked conduction electrons. When such electrons are induced to move along a straight wire, a magnetic field is generated around the wire. The magnetic field is due to regions of vorticity in the primordial fluid around the wire. These regions result from a criss-crossing of fixed and moving ether springs. The fixed ether springs link conduction electrons in metal objects outside the wire to positive ions in the wire. The axes of ether springs linked to the moving conduction electrons in the wire are straight and inclined forward through a small Lorentz angle so that they cross over the fixed straight ether springs linked to positive ions in the wire. It can be shown that the overlapping ether springs produce regions with a vorticity with vorticity vectors tangent to circles centered on the straight wire axis. Alternating currents will cause these regions of vorticity to move outward away from the wire corresponding to radio waves.

Unveiling the cosmological QCD phase transition through the eLISA/NGO detector

We study the evolution of turbulence in the early Universe at the QCD epoch using a state-of-the-art equation of state derived from lattice QCD simulations. Since the transition is a crossover we assume that temperature and velocity fluctuations were generated by some event in the previous history of the Universe and survive until the QCD epoch due to the extremely large Reynolds number of the primordial fluid. The fluid at the QCD epoch is assumed to be nonviscous, based on the fact that the viscosity per entropy density of the quark gluon plasma obtained from heavy-ion collision experiments at the Relativistic Heavy Ion Collider and the LHC is extremely small. Our hydrodynamic simulations show that the velocity spectrum is very different from the Kolmogorov power law considered in studies of primordial turbulence that focus on first order phase transitions. This is due to the fact that there is no continuous injection of energy into the system and the viscosity of the fluid is negligible. Thus, as kinetic energy cascades from the larger to the smaller scales, a large amount of kinetic energy is accumulated at the smallest scales due to the lack of dissipation. We have obtained the spectrum of the gravitational radiation emitted by the motion of the fluid finding that, if typical velocity and temperature fluctuations have an amplitude $(\ensuremath{\Delta}v)/c\ensuremath{\gtrsim}{10}^{\ensuremath{-}2}$ and/or $\ensuremath{\Delta}T/{T}_{c}\ensuremath{\gtrsim}{10}^{\ensuremath{-}3}$, they would be detected by eLISA at frequencies larger than $\ensuremath{\sim}{10}^{\ensuremath{-}4}\text{ }\text{ }\mathrm{Hz}$.

The quark-gluon plasma and the stochastic interpretation of quantum mechanics

Analysis of data from the relativistic heavy-ion collider (RHIC) has established that a quark-gluon plasma is formed in heavy-ion collisions, and that it is well described by an ideal classical fluid model with nearly zero viscosity. It is believed that a similar state of matter permeated the entire universe at about three microseconds after the big bang. The Reynolds number for this primordial fluid is estimated to be on the order 10 19 suggesting that the early universe was extremely turbulent. Could quantum behavior as we observe today possibly be a stochastic manifestation of this turbulent beginning? This paper explores this question by examining a particularly simple class of ideal fluids exhibiting turbulence and chaos in numerical simulations implemented utilizing a Fourier–Galerkin spectral truncation method. This proto-fluid model ignores pressure completely and is referred to in the cosmological literature as the Lambda-CDM model or cosmic dust model. It is compatible with a flat space-time provided a cosmological constant is included in the equations of general relativity, and it can be transformed into the inviscid Burgers equation. A new class of solitons is presented for this system. It is shown that these can be combined with the known chaotic solutions, and that they then move randomly with a mean velocity that does not decay with time, exhibiting a time-reversible stochastic motion without any friction, similar to quantum particles. The turbulent fluid is statistically a Markov process, and the soliton's position can be described by a hidden Markov model. It is also found that if the initial conditions for the fluid contain a single filament of vorticity, then a complex wave function which is single valued can be defined.

Acoustic oscillations in the early universe and today.

During its first approximately 100,000 years, the universe was a fully ionized plasma with a tight coupling by Thompson scattering between the photons and matter. The trade-off between gravitational collapse and photon pressure causes acoustic oscillations in this primordial fluid. These oscillations will leave predictable imprints in the spectra of the cosmic microwave background and the present-day matter-density distribution. Recently, the BOOMERANG and MAXIMA teams announced the detection of these acoustic oscillations in the cosmic microwave background (observed at redshift approximately 1000). Here, we compare these CMB detections with the corresponding acoustic oscillations in the matter-density power spectrum (observed at redshift approximately 0.1). These consistent results, from two different cosmological epochs, provide further support for our standard Hot Big Bang model of the universe.
