Y12.00001: A Study of Null and Time-Like Angular Geodesics in Kerr-De Sitter Space-Time Nabin Malakar, Udayaraj Khanal In this work, some aspects of the angular null and time-like geodesics in Kerr-de Sitter space-time are investigated. The trajectory, of massive and mass-less particles in various geometries, is described by the geodesics. In particular, trajectories of massive and mass-less test particles around a spherically symmetric gravitating-rotating body with asymptotically flat space-time is depicted by geodesic motion in Kerr space-time. A rotating black hole in asymptotically de Sitter space-time can be described by Kerr-de Sitter geometry. Such a space-time includes a finite cosmological constant ($\lambda$). Physically, $\lambda$ is related to the vacuum energy density and implies a pre-existing curvature. The trajectories, of particles around Kerr-de Sitter black hole in a circular orbit, are unstable and oscillate about the equatorial plane but do not reach the singularity. These geodesics are found to be confined within a maximum angle about the equatorial plane. This maximum angle is dependent on the cosmological constant. So it is inferred that the thickness of accretion disks should be related to the value of cosmological constant. [Preview Abstract] |

Y12.00002: The relativistic infinite plane Preston Jones In general relativity there have been several proposals as to what constitutes a uniform field. We give the gravitational field due to an infinite plane with finite mass per unit area, and show that this is the closest general relativistic analog to the Newtonian uniform field. Although we work in 4D we show that the 5D generalization of this solution is the starting point for many current research papers in particle physics and cosmology dealing with infinite extra dimension theories known as brane world models. This physical picture of the brane world models as higher dimensional versions of the general relativistic plane allows one to understand many of the features of these models in simple terms.

Y12.00003: Einstein's 1918 Position on the Role of Ether in Relativity Theory Tom Morton In his 1918 ``Dialog about Objections to the Theory of Relativity'' Einstein emphasized the potential applicability of the Ether concept in General Relativity. He noted that ``Lorentz brought a rigid substance embodying coordinate systems into play, but SRT denied the existence of all ether concepts. However, GRT is different, and empty space has physical qualities characterized as the components of gravitational potential. This situation can very well be interpreted by speaking of an ether whose state varies from point to point. However, one has to be careful not to attribute to this ether any matter-like properties such as a distinct velocity at each point.'' This presentation seeks to identify the qualities required of an ether. Concepts might include ether as a cause of gravity, and as the source medium for the production of electric charge. The ether might conceivably take the form of a diffuse mixture of positive and negative electric charge. [Preview Abstract] |

Y12.00004: Absolute Planck Values: Moving Beyond the Arbitrary Assignment of Unity John Laubenstein Planck Values provide a valuable tool in efforts to understand basic universal relationships; however, they fall short of having any truly intrinsic value. Planck Values come with the assumption that unity can be assigned to up to five of the fundamental universal constants. While constraining these values to unity may be convenient, it by no means ensures that intelligent life anywhere in the universe would make the same assumptions. Further, the peculiar value of the inverse fine structure constant of 137 suggests that it is naive to assume that any of the physical constants are equal to unity or any other simplistic value. Through an analysis of gravitation and electrostatic force, the IWPD Research Center has derived a logical argument for a revised set of Planck Values that represent absolute values with true universal significance. Of greatest importance, is a recalculated Planck Mass that serves as a truly fundamental unit of mass at the quantum scale. This finding contrasts with the significantly large value associated with the current Planck Mass and provides new information that may be critical in the search to unify General Relativity with Quantum Mechanics.

Y12.00005: Quantum Information, Entropy, ALPHA, Hubble Time, and Dark Energy, Linked? Shantilal Goradia The postulation of fundamental constants by Newton, Einstein and Planck gave us natural units at Planck scale. Additional postulates may explain coupling constants. About sixty orders of magnitude of Planck times equal Hubble time ($W)$. Substitution of $W$ in Boltzmann's entropy equation ($S=k$ \textit{ln} $W$; with Boltzmann constant $k $= 1 in natural units, and using the natural logarithm to probe nature) equates the statistical entropy ($S)$ of the universe to about 137, the reciprocal of the fine-structure constant (\textit{$\alpha $}). Thermodynamic entropy (\textit{dS} = $\delta Q$/$T)$, a consequence of statistical entropy, implies that the fine-structure constant generates heat out of vacuum energy or dark energy. We draw support from the insights of Maxwell's demon (1867), Gamow (1967) and Eddington (1949). In information theory, entropy is linked to a measure of uncertainty, indicating that the fine-structure constant is greater than or equal to the reciprocal of the natural logarithm of the age of the universe: $\alpha \ge 1 \mathord{\left/ {\vphantom {1 {lnW}}} \right. \kern-\nulldelimiterspace} {lnW}$. The postulation in [1] (a draft of a 2008 planned review paper) will address further issues. [1] S.

Y12.00006: A Zero free Parameter and Zero Counter Term Requirement Found By Replacing the Gauge Derivative General Covariance with Metric Nontrivial General Covariance in The Dirac Equation David Maker We replace the general covariance in the gauge derivatives in the Standard Model (SM) with a metric general covariance. The result is a new Dirac equation pde ($\surd $\textbf{\textit{g}}$_{\mu \mu }$\textit{$\gamma $}$_{\mu }$\textit{$\partial \psi $/$\partial $x}$_{\mu }$\textit{+i$\omega \psi $=0 }(sum on $\mu )$ with~g$_{oo}$=1-e$^{2}$/rm$_{e}$c$^{2}\equiv $1-r$_{H}$/r) requiring \textbf{no} free parameters, instead of the 18 of the SM, where here r$_{H}$ just sets the spatial scale. To illustrate the power of this technique we note here that equivalence principle considerations allow only \textit{one} type of charge e. Also g$_{oo}$ =0 at r=r$_{H}$ with stability the result. Note also that near r$_{H}$ the 2P$_{3/2}$ state for this new Dirac equation gives a azimuthal trifolium, 3 lobe shape; so this \textbf{ONE} charge e (so don't need \textbf{ color} to guarantee this) spends \textbf{1/3} of its time in each lobe (\textbf{fractionally charged} lobes), the lobe structure is locked into the center of mass \textbf{(asymptotic freedom}), there are\textbf{ six} 2P states (corresponding to the 6 flavors);~ which are the~~\textbf{main properties of quarks}!~without invoking free parameters. The S matrix of this new pde gives the W and Z as resonances and does not require renormalization counterterms or free parameters thereby restoring sanity to theoretical physics. It is vital that the physics community adopt this method if it is to break out of the 30 years of stagnation created by the confusion caused by these free parameters and counterterms.

Y12.00007: The Alternate Atomic Model Evan Ragland An alternate atomic model posits concentric electron and nucleon fields spinning together about an empty center. It is alternative to the generally accepted planetary system in which electron point particles orbit about a center clump of nucleon point particles. Introduced in 1992 as an alternative to the standard model of the nucleus it applies scientific space-time knowledge unknown when the standard model was conceived. Originally advanced in the spirit of alternative equivalence it evolved to model the entire atomic structure plus many features of space-time. Structural definitions assume space-time properties of: unidirectional expansion, special relativity, electrical field, magnetic field, spin field, gravity field, and space-time surface effect. Field effects are associated with Faraday lines of field force. Model properties feature symmetry and complementarily. Mass structures of the electron, proton,neutron, and protium atom plus the atomic and nuclear constituencies of all elements are developed. In addition the nuclear strong force is defined, the magnetic anomaly explained, etc. Model logic constructs the neutron as the complement of the hydrogen (protium) atom. [Preview Abstract] |

Y12.00008: Proof of the Wave Nature of Plants Orvin Wagner I assume plants operate with a set of frequencies. These frequencies and the means of these frequencies are equal in all directions. We can then write (v$_{h}$/$\lambda )_{avh}$=(v$_{v}$/$\lambda )_{avv}$ where the subscripts h and v represent horizontal and vertical respectively and av is average,. or v$_{v}$/v$_{h}$=(1/$\lambda _{h})_{av}$/(1/$\lambda _{v})_{av}$. I use an internodal spacing as $\lambda $/2 or the the distance between adjacent branches, leaves, etc. The ratios, v$_{v}$/v$_{h}$, are ratios of small integers for sufficient samplings. For example, for Ponderosa pine the ratio is 3/1 or for delicious apple 4/3. Note that these ratios represent the shape of the tree or other plant and their interactions with gravity. These ratios are derivable by other means such as use the ratio of {\#} of horizontal needles per unit length from a horizontal sample to the {\#} of needles per unit length from a vertical sample from p-pine. Or measure the vertical and horizontal velocities. My literature provides many other proofs of the wave nature of plants. I suggest that the waves in and related waves outside of plants (outside 4.9 m/s) are a dark matter related since they travel at such low velocities. See my present web site at home.budget.net/$\sim $oedphd. [Preview Abstract] |

Y12.00009: Post modern physic (a revolution in modern physics) Shahram Malekzadeh When you make a deep Study in Classic and modern physics you will find great and numerous weak points. On the other hand when you want to dismiss a wrong theory you should accept the other maybe incorrect theory so I think that we should write the physics from very beginning. Here I mentioned new theories on each field that can be a start for other scientists. Theories like ``cyclone theory'' which is about light travel or ``matrix theory'' which denotes that the materials are not made only atoms but an external capsule named matrix. [Preview Abstract] |

Y12.00010: The mass, energy, space and time system theory-MEST Dayong Cao Things have their own system of mass, energy, space and time of themself. (The MEST for short thereinafter). Mass is density, energy is force, time is frequency, spac is amplitude square. There are the transmutation between space-time and mass-energy. When they get a balance, they get the inertia and eigenvalue system. The inertia, eigenvalue and the transmutative balance system equation are being put forward. In quantum mechanics, the quality of radiate wave mainly is quantum space-time while it's mass-energy is ancillary; The nature of the macrosubstance is mainly mass-energy while space-time are ancillary. Mass-energy are like the earth center while space-time are like the heaven around. An Nuclear of an atom is like the earth center while the charge cloud of an atom(radiate wave) is like the heaven around. Macro is like the earth center while micro is like the heaven around. Physics system of The MEST of heaven and earth, which unites both macrophysics and microphysics. New space-time equation and photoelectric conversion equation are put forward, and get new mass-energy equation which equal the mass-energy relation of Einstein and the equation of electrodynamics. Black hole is space-time center while the dark matter-energy is the radiate mass-energy wave around Black hole. The dark matter-energy is from the Black hole. Black hole and Dark matter-energy can reduce the frequence of the light of star. [Preview Abstract] |
