  • Eccentricity Functions in the Higher Degree and Order Sectorial Gravitational Harmonic Coefficients (2011) [Updated 6 years ago]

    In the study of an Earth orbiting satellite, the terms of the series expansion of the Earth's gravitational potential can be expressed as functions of the eccentricity of the satellite. These functions are also known as eccentricity functions. The series expansion of these functions given by Kaula [2] appears to result in instabilities at high eccentricities. When calculating the eccentricity functions, researchers resort to numerical integration techniques instead. The approach followed in this contribution bypasses the problem of instability at high eccentricities by using a Hansen coefficient definition. As a test, we first calculate analytical expressions for various known eccentricity functions and then we proceed with the calculation of the eccentricity functions associated with degree and order 20, 30, 40, 50 sectorial harmonic coefficient expansion of the gravitational potential. Our calculation demonstrates the efficiency of Hansen coefficient approach that differs from that given by Kaula. It is efficient, fast, and can easily be performed with the help of a personal computer, with no instabilities at higher eccentricities.

  • The Mass of the Universe and Other Relations in the Idea of a Possible Cosmic Quantum Mechanics (2009) [Updated 1 decade ago]
    by Ioannis Iraklis Haranas, Michael Harney   read the paper:

    Recent observations confirm that galactic red-shifts might be quantized and hint a possible
    new form of quantum mechanics, which could probably explain these observed
    properties of the galaxies. This brief note investigates some expressions for the mass of
    the universe M(u), which were obtained with the help of the definition of the new cosmic
    Planck constant h bar subscript g.

  • SRT Lorentz Transformation Derived from WSM (2008) [Updated 1 decade ago]

    The SRT frequency shift, time dilation and energy equivalence formulas are derived from wave structure of matter concepts. The derivation shown removes Einstein?s requirement for the constancy of the speed of light between reference frames, which is not necessary in producing the results of the Lorentz transforms. Also, the photon is revealed to be the interaction between two electron wave centers, not a separate particle, showing a preference for Tetrode's concept of a photon.

  • GRT Time & Frequency Shifts Derived from WSM (2008) [Updated 6 years ago]

    Schwarzschild's g44 solution for time dilation and frequency shift of light are derived from wave structure of matter concepts as opposed to General Relativity. This corroborates the origin of time and frequency shifts predicted by the wave structure of matter and the nature of a photon. This derivation relates known values with the properties of the Universe, and shows the origin of the Newtonian gravitation constant.

  • Derivation of the Schwarzchild Solution from a Scalar Model of Spherical Quantum Waves (2008) [Updated 6 years ago]

    It is shown that if space is modeled as an elastic medium that propagates spherical, scalar quantum-waves, then the ratio of the square of the wave velocity to c2 reveals the same results as the familiar time dilation formula that is produced from the Schwarzchild G44 component. The Schwarzchild radius derived from the scalar-wave model is shown to be equal to the radius of the universe, implying that there are no gravitational singularities present within the radius of the Universe.

  • Geodetic Precession of the Spin in a Non-Singular Gravitational Potential (2008) [Updated 1 decade ago]
    by Ioannis Iraklis Haranas, Michael Harney   read the paper:

    Using a non-singular gravitational potential which appears in the literature we analytically
    derived and investigated the equations describing the precession of a body?s spin
    orbiting around a main spherical body of mass M. The calculation has been performed
    using a non-exact Schwarzschild solution, and further assuming that the gravitational
    field of the Earth is more than that of a rotating mass. General theory of relativity predicts
    that the direction of the gyroscope will change at a rate of 6.6 arcsec/year for a
    gyroscope in a 650 km high polar orbit. In our case a precession rate of the spin of a
    very similar magnitude to that predicted by general relativity was calculated resulting
    to a (Delta)Sgeo / Sgeo = -5.570x10-2.

  • Detection of the Relativistic Corrections to the Gravitational Potential using a Sagnac Interferometer (2008) [Updated 6 years ago]
    by Ioannis Iraklis Haranas, Michael Harney   read the paper:

    General Relativity predicts the existence of relativistic corrections to the static Newtonian potential which can be calculated and verified experimentally. The idea leading to quantum corrections at large distances is that of the interactions of massless particles which only involve their coupling energies at low energies. In this short paper we attempt to propose the Sagnac intrerferometric technique as a way of detecting the relativistic correction suggested for the Newtonian potential, and thus obtaining an estimate for phase di
    erence using a satellite orbiting at an altitude of 250 km above the surface of the Earth.
