    Einstein : Gravity.
    =.
    Einstein, you was mistaken using your Gravitation theory
    to the all Universe as a whole.
    The Gravitation theory doesn’t work in the Universe as a whole.
    The Gravitation theory is a local theory.
    Why?
    Because the detected material mass of the matter in the
    Universe ( the cosmological constant / the critical density)
    is so small ( the average density of all substance in the
    Universe is approximately p=10^-30 g/sm^3 ) that it
    cannot ‘close’ the Universe into sphere and therefore our
    Universe as whole must be ‘open’, endless, infinite.
    The Universe as a whole is an Infinite Pure Vacuum: T=0K.
    More concrete:
    The parameters of Vacuum: T= 0K, E= ∞ , p = 0, t =∞ .
    =.
    We have two (2) Worlds: Vacuum and Material and we need
    to understand their interaction.

    I think you are misunderstanding this. GR does not dictate any particular model of the universe ( closed, open or otherwise ), it only provides a relation for all the possible geometries. Refer to the simplest cosmological solution of the field equations, the Robertson-Walker metric :



    The time dependent function R(t) here describes the evolution of the universe ( and is determined via the interior field equations with cosmological constant ), whereas the parameter k distinguishes the topologies :

    k = -1 : Hyperbolic universe ( open, but curved )
    k = 0 : Flat universe ( open, no curvature )
    k = 1 : Closed universe ( closed, with curvature )

    Sorry socratus. I'm perfectly happy to transfer this back into Physics or maybe New Hypotheses, or have another moderator do so.

    But only if you provide much better argument and analysis to justify such a promotion.

    Einstein (Still) Rules The Universe
    . . .
    Each team of scientists took advantage of extensive Chandra observations of galaxy clusters,
    which are cosmic formations that can contain anywhere from 10 to thousands of galaxies.
    These clusters are the largest objects in the universe bound together by gravity.

    . . . . thousands of galaxies.
    It means that GRT is used for the universe as a whole

    Of course it is. See post 2.
