Harvard Physicists Make Light Dance

tetrikphimvin and others clued us to the latest work by Harvard's Lene Vestergaard Hau, being published today in the journal Nature. The NYTimes has a good layman's overview of how Hau's team encoded a light beam in a clump of atoms and later reconstituted it elsewhere. The Harvard Gazette offers additional details, a photo, and video links.

  1. Re:relativity as light is just surfing the expandi by 22RealMcCoy · · Score: -1, Troll

    As light is just surfing the expanding foruth dimension, slowing light dwn just means you're holding the momenergy back as the crests of the fourth expanding dimension surge forward.

    This appens all the time in glass and other meidums wherin the index of refraction is greater than one.

    The fourth dimension is expanding relative to the three spatial
    dimensions. Moving Dimensions Theory accounts for the aetherless aether.

    This simple postulate offers a physical model underlying and unifiying:

    RELATIVITY:

    1) length contraction
    2) time dilation
    3) the equivalence of mass and energy
    4) the constant velocity of light
    5) the independence of the speed of light from the velocity of the source

    QUANTUMN MECHANICS
    1) action at a distance
    2) wave-particle duality
    3) interference phenomena
    4) EPR paradox

    THERMODYNAMICS
    1) Time's arrow
    2) Entropy

    STRING THEORY'S MANY DIMENSIONS / KALUZA/KLEIN THEORY
    1) a fourth expanding dimension can be interepreted as many dimensions, each time it expands

    THE UNITY OF THE DUALITIES
    1) wave/particle duality
    2) time/space duality
    3) energy/mass duality
    4) E/B duality

    GENERAL RELATIVITY
    1) Gravitational redshift
    2) Gravity waves
    3) Gravitation attraction

    THE SPACE-TIME BACKGROUND
    1) quantum foam
    2) the smearing of space and time at small distances
    3) Hawking's imaginary time

    PARADOXES
    1) MDT explains away Godel's Block Universe
    2) MDT unfreezes time
    3) Resolves Zeno's Paradox

    ONE GETS ALL OF THIS FROM A SIMPLE POSTULATE:

    The fourth dimension is expanding relative to the three spatial
    dimensions in a sphereically symmetric manner, in units of the Planck length, at the rate of c.

    This means that every point in three dimnesional space is always expanding into a fourth dimensional sphere with a radius of the plank length. A photon is matter caught on the surface of this quantized expansion, and thus energy is quantized. The expansion of the fourth dimension occurs at the rate of c, and thus the velocity of all photons is c.

    Check out the t-shirt with a simple proof of MDT:

    http://www.cafepress.com/autumnrangers.72464949

    "The only way to stay stationary in the fourth dimension is to move at the speed of light through the three spatial dimensions. Ergo the fourth dimension is expanding at the rate of c relative to the three spatial dimenions."

    How sad it is that when truth stares modern physicists in the face, they must close their eyes so as to get a postdoc or raise more funds for String Theory.

    Moving Dimensions Theory is in complete agreement with all
    experimental tests and phenomena associated with special and general relativity. MDT is in complete agreement with all physical phenomena as predicted by quantum mechanics and demonstrated in extensive experiments. The genius and novelty of MDT is that it presents a common physical model which shows that phenomena from both relativity and quantum mechanics derive from the same fundamental physical reality.

    Nowhere does String Theory nor Loop Quantum Gravity account for quantum entanglement nor relativistic time dilation. MDT shows these derive from the same underlying physical reality. Nowhere does ST nor LQG account for wave-particle duality nor relativistic length contraction. MDT shows these derive from the same underlying physical reality. Nowhere does ST nor LQG account for the constant speed of light, nor the independence of the speed of light on the velocity of the source, nor entropy, nor time's arrow. MDT shows these derive from the same underlying physical reality. Nowhere does String Theory nor
    Loop Quantum Gravity resolve the paradox of Godel's Block Universe which troubled Eisntein. MDT resolves this paradox.

    Simply put, MDT replaces the contemporary none-theories with a physical theory, complete with a simple postulate that unifies
    formerly dispar

    This is about the dumbest "theory" I've ever heard. The fourth dimension is "expanding?" As in, from one moment in time to another, it's getting bigger? Wait a second, did I just say "moment in TIME?" So you're defining time in terms of an expansion over TIME? You are stupid.
