Dark energy redshifts cmbr photons

In summary, 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 of 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, or 10

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
of
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
photons
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.
 

What is dark energy?

Dark energy is a theoretical type of energy that is thought to make up about 70% of the total energy in the universe. It is believed to be responsible for the observed accelerated expansion of the universe.

What causes redshifts in the universe?

Redshift is a phenomenon where the wavelength of light from a distant object appears longer than it actually is, making it appear "redder". This is caused by the expansion of the universe, which stretches the wavelength of light as it travels through space.

How does dark energy affect the redshift of cosmic microwave background (CMB) photons?

Dark energy is believed to have a negligible effect on the redshift of CMB photons. This is because the CMB radiation was emitted at a time when the universe was much younger and the effects of dark energy were not significant.

What is the significance of studying dark energy through redshifts of CMB photons?

Studying the redshifts of CMB photons can provide valuable information about the expansion rate and composition of the universe. It can also help us understand the role of dark energy in the evolution of the universe.

How does dark energy relate to the expansion of the universe?

Dark energy is thought to be the driving force behind the accelerated expansion of the universe. It exerts a repulsive force that counteracts the attractive force of gravity, causing the expansion rate to increase over time.
