    What is relation between the cosmological

    constant and the dilaton field or cosmon?

    Now my problem has changed from coordinate

    frame. If I can convince there can be torsion in any frame, I would believe that the coordinate frame acquired through a linear transformation from that frame also has the torsion. The initial derivation of connection is from the Gauss equation without assuming the ambient...

    THEOLOGICAL PHYSICS Version date: 22 December

    2014 In an earlier paper, the authors proposed a model where the universe is composed of precisely equal amounts of positive mass/energy and negative mass/energy, now segregated into two precisely concentric, intermeshed, mutually repulsive, expanding spheres...

    Symmetry Wins -- Including Mass

    Version date 9 October 2013 Symmetry wins -- including mass Whether the universe is a dream of Brahma, a week's work by Yahweh, or something else, it is deeply symmetric: equal amounts of positive and negative electric charge; north and south magnetic poles; clockwise and...

    Quantum Mechanics

    tells us that atoms repel one another through magnetic force but otherwise are mostly empty space. However at least in theory if all the atoms aligned themselves just right then they could pass through one another. Housewife's believe that laundry machines must cause this...

    (£_ξA)^i=[ξ,

    A]=dA^i(ξ)-dξ^i(A)=DA^i(ξ)-Dξ^i(A) in a symmetric connection. Thus the torsion T(ξ, A)=∇_ξA-∇_Aξ-[ξ, A] measures the deviation from the symmetric connection. I wonder why in a coordinate frame, torsion doesn't necessarily vanish.

    It turns out that the cosmological perturbation

    is just the amplification of the vacuum fluctuation by the universe inflation.
