que esta visao de teleologia ate no fisico e muito bem destruida por Hume.E por favor, criacionistas achando que entendem de Termodinamica em Cosmologia: vou ter de repetir que a nocao que o universo tenha de ter sido "aquecido" para possuir sua energia e uma tonteira completa?E falando em multiversos, que por si so ja fazem em pedacos este assunto de "nosso criado por Jeova universo...:George F.

J.; Farina, C.; Cougo-Pinto, M. V.; Past and Future Blurring at Fundamental Length Scale; Physical Review Letters, vol. 105, Issue 21, id. 211601 DOI: 10.1103/PhysRevLett.105.211601 - arxiv.org - adsabs.harvard.eduWe obtain the -deformed versions of the retarded and advanced Green functions and show that their causality properties are blurred in a time interval of the order of a length parameter q=1/(2). The functions also indicate a smearing of the light cone. These results favor the interpretation of q as a fundamental length scale below which the concept of a point in space-time should be substituted by the concept of a fuzzy region of radius q, as proposed long ago by Heisenberg.2J. A. S. Lima and R. Portugal; Bulk-viscosity-driven asymmetric inflationary universe; Phys. Rev. D 37, 27552760 (1988) - journals.aps.orgA primordial net bosonic charge is introduced in the context of the bulk-viscosity-driven inflationary models. The analysis is carried through a macroscopic point of view in the framework of the casual thermodynamic theory. The conditions for having exponential and generalized inflation are obtained. A phenomenological expression for the bulk-viscosity coefficient is also derived.3Observe-se que um universo inflacionario assimetrico nao deve ser confundido com assimetrias da materia escura.David E. Kaplan, Markus A. Luty, Kathryn M. Zurek; Asymmetric Dark Matter; Phys.Rev.D79:115016,2009 - DOI: 10.1103/PhysRevD.79.115016 - arxiv.orgWe consider a simple class of models in which the relic density of dark matter is determined by the baryon asymmetry of the universe. In these models a BL asymmetry generated at high temperatures is transfered to the dark matter, which is charged under BL. The interactions that transfer the asymmetry decouple at temperatures above the dark matter mass, freezing in a dark matter asymmetry of order the baryon asymmetry. This explains the observed relation between the baryon and dark matter densities for dark matter mass in the range 5--15 GeV. The symmetric component of the dark matter can annihilate efficiently to light pseudoscalar Higgs particles a, or via t-channel exchange of new scalar doublets. The first possibility allows for h0aa decays, while the second predicts a light charged Higgs-like scalar decaying to . Direct detection can arise from Higgs exchange in the first model, or a nonzero magnetic moment in the second. In supersymmetric models, the would-be LSP can decay into pairs of dark matter particles plus standard model particles, possibly with displaced vertices.4Mads T.
