Dark energy redshifts cmbr photons

  1. May 20, 2004 #1
    Dark energy waves absorb energy from photons in intergalactic space
    and the total energy of dark energy increases,
    increasing the acceleration of the universe.
    Because the dark energy is quantised when it absorbs
    energy from a photon it changes to a higher energy
    quantum state.If a cosmic microwave background photon has a wavelength
    10^ - 3 metres - an energy of 10^-23 J- then before it was redshifted
    it had an energy 1000 times greater-10^ -20 J.Over 10^26 metres - the
    current size of the universe - the photon loses 10^-20 - 10^-23 J =
    10^-20 J.
    This is 10^-20/10^26 J/m i.e 10^ - 46 J /m. If an absorption of
    photon energy by dark energy takes place every 10^ -14 seconds - the
    photon will travel 10^-6 metre before emitting 10^-46 x 10^-6 = 10^-52 J to
    dark energy waves. Using h = E x t we find that
    10^ - 52 x t = 10^ - 34
    t = 10^18 seconds.
    This means that dark energy will emit the energy it has picked up from
    10^18 seconds after having done so -the current age of the universe.
    When it does emit the photon energy the universe will deccelerate as
    the amount of dark energy decreases and gravity dominates.

    Is this your idea or do you have a reference?

    My idea.
    I think dark energy undergoes a phase change when it absorbs energy from photons.
    If you think of a photon as water and dark energy as water,dark energy absorbs
    energy from photons and becomes steam - a gas exerts a greater pressure than a liquid.

    Does dark energy absorb energy from photons and cause them to redshift?
    Someone told me that the redshift would probably be higher than is experimentally observed if this idea was right, but they didn't give details of why. Can someone tell me why the redshift would be higher? And if dark energy isn't uniformly distributed at every point in space - if it was distributed like a uniform volume of atoms- could that reduce the redshift back to the experimentally observed redshift?
    Can dark energy consist of individual quantized particle pairs of
    some kind?
    Apparently quintessence models have difficulty producing the supposed
    flatness of the dark energy distribution in a natural way.There is a
    paper on the arxiv that models dark energy as phenomenon with three mutually orthogonal Vectors to guarantee isotropy.Is dark energy a
    vector phenomenon?
    If dark energy absorbs energy from photons and expands it could keep its energy density constant - in other words, can dark energy be space-time?
    Space -time is expanding too.
