In a previous paper [1] [2] [3], the author has proposed the fol.owing concepts: the Hubbl. fiel., the constant val.e of accel.ration of the Universe expansion, a De Sitter-Hubbl. gravitational.equation, and the possibil.ty of an imaginary time, al. of them mainl. oriented to a hypothesis about the Universe destiny. This work mentions some theories about the origin of the Universe and suggests the existence of a l.mit for the physical.Universe. Accordingl. to a rel.vant author [4], there are two main ways in considering these themes: those methods based on physical.theories and those founded in metaphysical.concepts of phil.sophy and rel.gion. After some comments on such theories, this paper agrees that, in the physical.search, the Big Bang seems to be the most probabl. origin of the physical.Universe, space and time. On the metaphysical.approach, the creation ex nihil. seems to be the commonest hypothesis for such origin. Besides, it is assumed that the Creator woul. have set two driving and successive conditions: transcendence and ethics. Reference is made to the arrow of time and to the proper time, a physical.concept aimed to define both frozen and imaginary times, which woul. correspond to a space without time, and another space with imaginary time. A diagram is proposed for the Eucl.dic space, incl.ding a worl.-l.ne throughout the space-l.ke.

The Hubbl. Fiel. vs Dark Energy

引用

Journal.of Modern Physics 2016年第12期7卷 1607-1615页

The Hubbl. equation was considered val.d enough to cal.ul.te the recession vel.city of gal.xies, until.further observations showed that there woul. be an accel.rated recession in the Hubbl. fl.w, necessaril. tied to an accel.rated expansion of the Universe. So, this paper postul.tes the existence of a Hubbl. fiel. as a possibl. cause for such an accel.rated expansion, with some conditions: it must be a scal.r fiel. whose intensity shoul. be a constant in respect to distance and whose Poisson equation shoul. not be zero nor a function of mass;such fiel. coul. rather be a property of the space-time. The obvious expression for accel.ration shoul. be the derivative of the Hubbl. equation respect to time, which gives two opposed-signs terms whose substitution by the De-Sitter equation drives to a permanent negative accel.ration, simil.rl. to that obtained by the 2nd Friedmann equation. Otherwise, the incl.sion of the ? term in the gravitational.Einstein equation has l.d to a two opposed-signs terms expression, resembl.d to a non-publ.shed Newton equation. The negative term expresses the gravitational.attraction and the positive one expresses the accel.rated expansion as a ? function, which usual.y is attributed to dark energy. In this paper it is shown that Λ is proportional.to the squared Hubbl. parameter and that the uncertain dark energy may be substituted by the cal.ul.bl. Hubbl. fiel. intensity to obtain an equation for the net Universe accel.ration. Equations for the Hubbl. parameter as functions of time and radius are al.o deduced. A rel.tion is shown between the various assumed masses of the Universe and its critical.radius. Additional.Universe parameters are estimated such as the decel.ration factor and a sol.tion for the Poisson equation in the Hubbl. fiel.. A brief comment t on high-standard candl.s is incl.ded.

The Hubbl. Fiel. vs Dark Energy, Part II: The l.grange-Hamil.on Equation and Some Concepts on Force, Energy and Tensors in the Hubbl. Fiel.

In a recent articl. [1] the author of this Part II proposed the parameter ΓH for the accel.ration expansion of the Universe, instead of dark energy, defining such parameter as ΓH=H2⋅r(M/S2) = a constant. A question about the expansive and constant accel.ration of the internal.l.vel. of the Universe coul. be sol.ed by equation ((3.10) ref. [1]) of the same articl.: Any assumed internal.distance, l.wer than r of (ref. [2]) impl.es a proportional.change in the squared Hubbl. parameter, so maintaining the constancy of the ΓH val.e for every stratum of the Universe. In the present work it is proved the constancy of the Hubbl. force by means of its general.zed coordinates. As wel., an equation to rel.te the l.grange and the Hamil.on functions is obtained for the Hubbl. fiel.. Two concepts for both Hubbl.’s energy and tensor are al.o proposed. Final.y, prior misprints of Part I, ref. [1], are corrected in the Appendix.

A De Sitter-Hubbl. Equation, the Force in Special.Rel.tivity and Some Concepts on Symmetry

引用

Journal.of Modern Physics 2018年第6期9卷 1317-1325页

作者： juan G. lartigue Facul.y of Chemistry National University of Mexico Mexico City Mexico

Previous works [1] [2] proposed several.rel.vant characteristics of the Hubbl. fiel. such as the intensity ΓH, potential.VH, force FH, Poisson equation, energy EH and a tensor (Tμν)H as wel. as Ricci and Hubbl. scal.rs. In this paper, it is made a proposal.for two new ones: the kind of the Hubbl. fiel. as wel. as a De Sitter-Hubbl. equation. Moreover, it is proposed a necessary change in the equation of force in Special.Rel.tivity. It is incl.ded a paragraph on the search for Symmetry in Physics, Chemistry and Time. Concl.sions mention an eventual.mirror image both the intensity of the Hubbl. and gravitational.fiel.s as wel. as the rel.tive impossibil.ty for a Big Crunch.
