Dark energy redshifts cmbr photons

Click For Summary

Discussion Overview

The discussion revolves around the interaction between dark energy and cosmic microwave background (CMB) photons, specifically focusing on the idea that dark energy absorbs energy from these photons, leading to redshift effects. Participants explore theoretical implications, potential models, and the nature of dark energy, including its distribution and properties.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • One participant proposes that dark energy waves absorb energy from photons, increasing the total energy of dark energy and accelerating the universe.
  • Another participant questions whether this idea is original or based on existing references.
  • A participant suggests that dark energy undergoes a phase change upon absorbing photon energy, comparing it to water turning into steam.
  • There is a query about whether dark energy's absorption of photon energy would lead to a redshift greater than what is observed, with a request for clarification on this point.
  • Concerns are raised about the uniformity of dark energy distribution and its potential effects on redshift measurements, including the possibility of dark energy being distributed like a uniform volume of atoms.
  • Participants discuss the idea of dark energy consisting of quantized particle pairs and reference quintessence models, noting challenges in explaining the flatness of dark energy distribution.
  • One participant introduces a paper suggesting that dark energy can be modeled as a phenomenon with three mutually orthogonal vectors to ensure isotropy.
  • There is speculation about whether dark energy could be considered a space-time phenomenon, especially in the context of the expansion of space-time itself.

Areas of Agreement / Disagreement

Participants express a range of views on the nature of dark energy and its interaction with photons. There is no consensus on the mechanisms involved, the implications for redshift, or the characteristics of dark energy itself.

Contextual Notes

Participants highlight various assumptions regarding the behavior of dark energy, the uniformity of its distribution, and the implications of different models on observed phenomena. These assumptions remain unresolved within the discussion.

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.
