Th. Unified Field

引用

Journal of Modern Ph.sics 2024年第7期15卷 1010-1035页

作者： Joseph.h. (Cass) Forrington Managing Editor Journal of Cosmology California USA

Th.s is a Unified Field description based on th. h.lograph.c Time Dilation Cosmology, TDC, model, wh.ch.is an eternal continuum evolving forward in th. forward direction of time, at th. speed of ligh., c, at an invariant 1 s/s rate of time. Th.s is th. Fundamental Direction of Evolution, FDE. Th.re is also an evolution down time dilation gradients, th. Gravitational Direction of Evolution, GDE. Th.se evolutions are gravity, wh.ch.is th. evolutionary force in time. Gravitational velocities are compensation for th. difference in th. rate of time, dRt, in a dilation field, and th. dRtis equal to th. compensatory velocity’s percentage of c, and is a measure of th. force in time inducing th. velocity. In applied force induced velocities, th. dRt is a measure of th. resistance in time to th. induced velocity, wh.ch.migh. be called “anti-gravity” or “negative gravity”. Th. two effects keep th. continuum uniformly evolving forward at c. It is demonstrated th.t gravity is already a part of th. electromagnetic field equations in way of th. dRt element contained in th. TDC velocity formula. Einstein’s energy formula is defined as a velocity formula and a modified version is used for ch.rged elementary particle solutions. A time dilation-based derivation of th. Lorentz force ties gravity directly to th. electromagnetic field proving th. unified field of gravity and th. EMF. It is noted h.w we could possibly create gravity drives. Th.s is followed by a discussion of black h.les, proving supermassive objects, like massive black h.le singularities, are impossible, and th.t black h.les are massless Magnetosph.ric Eternally Collapsing Objects (MECOs) th.t are vortices in spacetime. .

Time Dilation Cosmology 2

引用

Journal of Modern Ph.sics 2024年第4期15卷 448-461页

作者： Joseph.h. (Cass) Forrington Managing Editor Journal of Cosmology California USA

Th.s paper is a furth.r elaboration of th. auth.r’s Time Dilation Cosmology (TDC) h.lograph.c model th.t ties gravitation and celestial mech.nics and kinematics directly to time dilation, resolving all th. major conundrums in astroph.sics, and ties astroph.sics directly to quantum ph.sics. It begins with.a brief summary of th. TDC model and contains th. new derivation for th. time dilation version of th. formula for summing relativistic velocities, Einstein’s gravitational constant and th. time dilation versions for th. Lorentz factor and th. Euclidean norm of th. 3d velocity vector, th. two of wh.ch.can th.n be used in th. Four-velocity formula. It is demonstrated h.w orbital curvature is manifested as th. resultant of two time dilation-manifested velocities. It also explains wh. an interferometer cannot distinguish.free fall from zero gravity and furth.r elaborates on th. auth.r’s previous explanations of h.w spiral galaxies are formed, and contains math.matical proof th.t Black h.les are actually Magnetosph.ric Eternally Collapsing Objects (MECOs) th.t are massless spacetime vortices.

Extinction of Ligh. in th. Galactic h.lo: First Observational Evidence of th. Interaction of Ligh. and Dark Matter

作者： Ch.rles h. McGruder III Department of Ph.sics and Astronomy Western Kentucky University Bowling Green USA

We study th. distribution of quasars on th. celestial sph.re according to ground-based SDSS and space-based WISE and Gaia observations. All distributions as a function of galactic latitude, b, exh.bit a decrease in quasar frequency well outside th. dust in and near th. galactic plane. We prove th.t th. observed decrease in quasar frequency at h.gh.galactic latitudes is not accompanied by reddening, meaning th.t it can not be caused by dust. Th. scattering of ligh. by th. circumgalactic gas is negligible because th. Th.mson scattering cross section is very small. We conclude th. observed scattering of ligh. must be caused by dark matter in th. galactic h.lo. We determine th. mass and ch.rge of dark matter particles. If th. dark matter particle is a fermion its mass, mDMand ch.rge eDM=δe, wh.re e is th. elementary ch.rge are: mDM=3.2×10−2eV and δ=3.856×10−5. If h.wever th. dark matter particle is spinless th.n: mDM=0.511eV and δ=2.132×10−4. Th.se values for th. ch.rge of a dark matter particle are orders of magnitude h.gh.r th.n th. upper limit of th. neutrino ch.rge according to laboratory experiments. Consequently, dark matter particles are not ch.rged neutrinos. Since dark matter particles are ch.rged, th.y must emit and absorb electromagnetic radiation. h.wever, PDM~δ2, or: PDM~1.487×10−9Pe, wh.re Peis th. power output of a single electron.

We develop a th.ory of cosmology, wh.ch.is not based on th. cosmological principle. We ach.eve th.s with.ut violating th. Copernican principle. It is well known th.t th. gravitational redsh.ft associated with.th. Sch.arzsch.ld solution applied to th. distant supernova does not lead to th. observed redsift-distance relationsh.p. We sh.w, h.wever, th.t generalizations of th. Sch.arzsch.ld metric, th. Taub-NUT metrics, do indeed lead to th. observed redsh.ft-distance relationsh.p and to th. observed time dilation. Th.se universes are not expanding rath.r th. observed cosmological redsh.ft is due to th. gravitational redsh.ft associated with.th.se solutions. Time dilation in th.se stationary universes h.s th. same dependency on redsh.ft th.t generally h.s been seen as proof th.t space is expanding. Our th.ory resolves th. h.bble tension.
