Flat Screen Universe

  1. Aug 17, 2004 #1
    Studies of black hole physics by people like Hawking and Bekenstein suggests that our perceptual universe, which is perceived to have three spatial dimensions, might instead be "written" on a two-dimensional surface, analogously to a computer generated holographic projection. The everyday perceptions of our world as three-dimensional could be a type of optical delusion of our consciousness, or merely one of two alternative ways of describing reality.

    The universe could be a system of discrete interlocking "pixels" encoded on a 2-dimensional substrate.


    A quote from the book "The Expanding Universe" by Sir Arthur


    All change is relative. The universe is expanding relatively to our
    common standards; our common standards are shrinking relatively to the size of the universe. The theory of the "expanding universe" might
    also be called the theory of the "shrinking atom" .

    Holography uses light in a manner that produces three-dimensional images on a photographic plate or film. A holographically generated universe, would cause an observer to see the universe as being without limits, and at the same time the universe would be finite.

    The holographic universe would be "painted" on a spherical surface of 2 dimensions and projected inward, retaining an appearance of being without limit.

    Information exchange among physical processes would take precedence over fields or space-time.

    Each event in space-time has its own intrinsic measure of time, its own "present moment", which is a point in the the separation plane of past and future, with the future as an uncertainty.

    Why not represent the present moment of an arbitrary observer as the inward collapse of the "past" light-cone/circular cross section to the point of the "present moment" and the outward expanse of the future light-cone/circular cross section into the uncertain future.

    A 2-dimensional planar "cross-section" of the present moment, which is the overlapping of past history, present moment, and future uncertainty.
    p is the observational center of the overlapping cross sections. The "proper time".


    Now it appears that the "past" moments are cumulative and are increasing in information density = Shannon entropy as a cumulative overlapping of Lorentz invariant circular cross sections via holographically generated[discrete] pixels.

    That is more science fiction than fact. Observation outweighs theoretical speculations. Try to bear in mind that observation is the independent variable.

    Lorentz invariance is an established scientific "observation". :eek:

    Brainstorming is not forbidden in "physics".

    Disagreed. Lorentz invariance is not an 'observation'. It is a mathematical construct affirmed by observation. Similarily, brainstorming is not forbidden by 'physics'. It is, however, frequently forbidden by observation.

    The constancy of the speed of light in vacuum is an "observation".

    What is more important, imagination or ...observation?
