Could Dark Energy Be Explained by Gravitons?

Click For Summary
Dark energy may be linked to a vast number of gravitons, which could be emitted by redshifting photons as they travel between galaxies, potentially maintaining a constant density of dark energy. Gravitons, unlike photons, are theorized to be the quantized waves of spacetime, making them difficult to detect, and they are not currently believed to be emitted by photons. The origin of dark energy remains a mystery, often associated with antigravity forces in an inflationary universe, which is a more advanced concept than the Big Bang singularity. Theoretical models, including Kaluza-Klein and superstring theories, have attempted to unify gravity and electromagnetism but have not yet succeeded. Overall, the discussion highlights the complexities of understanding dark energy and its relationship with fundamental forces in the universe.

Isn't this just some sort of three superdimensional concept?

Its four of space and one of time.

No it includes GR and QM. From a supersymmetrical state for sure, but it can be derived from the metric to supermetric points of supergravity


The degree of freedom (dof) for each dimension, I am associating it with the number of closest neighbors for a given spacetime point. 2 dof for 1D, 4 dof for 2D, 6 dof for 3D, 8 dof for 4D, 10 dof for 5D, 12 dof for 6D, 14 dof for 7D, 16 dof for 8D, 18 dof for 9D, 20 dof for 10D, etc.
I am not sure I understand this.

I don't agree with the string theorists that dimension can be compacted. For me, compactification deals with size and shape not with motion. I am concentrating my efforts on understanding how and why space can be attributed with motion. What I have found out so far is that I can only do this with 1D space and the things quantized are the directions not the magnitudes of the vector quantities in the theory but this quantization is only at the local infinitesimal region of spacetime, in the neighborhood of one point and its associated closest neighbors. The distance d^2 = m^2 + n^2 + l^2 - (\vec{a} \cdot \vec{r}) t^2 is defined not to the closest neighbors but to the infinite minus closest points points. By itself, the distance, d, shows a hyperbolic geometry. It will take two of this d to form an elliptic geometry of spacetime.

If you considered how photon interaction is affected with the theoretical definition of the graviton( witten must have shown this somewhere) it might have made sense to consider the long and short of the photon?

Even at great distances in the comso we are still talking about the distances of the very small. Do you see what I am saying. That if metric point of GR can be made more supermetrical what are we talking about? The energy is very important here in discribing of that early universe, as well as speaking to the scalable nature of gravity from strong to weak?

Am I right to say this make sense only for string theory? Long means more energy and short means less energy? But in string theory, gravitons are closed string ( a loop). In my theory of H-plus and H-minus, gravitons are also loops but each graviton is made of a double linked loops. These loops can be linked in two ways, an H-plus way and an H-minus way.
