Gravitational time dilation of photons explains Dark Energy
Thanks John. Time is just a measure of the rate of change. Like in General Relativity, as a photon travels through curved space, it takes longer for the photon to travel between two quantum points in space since they are stretched apart, which would mean a stretch in frequency and a slower time would be measured, and c = c. I revised my original post to keeping this in mind.

Gravitational time dilation of photons explains Dark Energy
To clear things up and support original post, that gravitational time dilation of photons during gravitational redshifting would result in a lose of energy from the photons, into the stretching of space, and being the energy source behind Dark Energy. Here's a more solid explanation: In General Relativity, a photon that looks like it was redshifted by the relative motions of galaxies, could actually have been gravitationally redshifted by gravitational time dilation. The results would be the same! Supported here: http://hyperphysics.phy-astr.gsu.edu/hbase/relativ/gratim.html#c1 There are a lot of photons (of all frequencies), out there, and they're all going through gravitational time dilation out there! All of them! Also, galaxies put all sorts of photons out, and there still is all of that cosmic background radiation. Since there are a lot of photons out there going through gravitational redshifting, it's not too far of a stretch to say, that is a lot of energy that could potentially lost into space, from gravitational redshifting! *side note: what happens when all of that cosmic background radiation falls into the deep gravity wells of galaxies? Depends on source I suppose? In other places there would be a gain of energy into space, during gravitational blueshifting, where photons arrive into deeper gravity wells, with more energy than they had, when they left the shallower gravity well. The net lose of energy in photons going from higher gravitational fields (heavy galaxies) to lower gravitational fields (lighter galaxies) will have been lost into the stretching of space, again due to the gravitational time dilation of photons during gravitational redshifting. The converse would also be true.

To clear some things up, and to support original post about gravitational time dilation of photons, during gravitational redshifting, as being the root source of Dark Energy: In General Relativity, a photon that was redshifted by the relative motions of galaxies, could actually have been gravitationally redshifted, by gravitational time dilation, and the results would be the same!

Gravitational time dilation of photons explains Dark Energy
Wouldn't it only be balanced out if the photon left and entered the same dimensioned gravity wells though? I concede that the redshift of light between galaxies is due to the motion of the galaxies moving away from each other. It could be by some other processes, similar to those in gravitational time dilation, that result in an expansion of space from loss of energy in photons. Some other interactions of photons with space, or that result in collisions, maybe. Just really seems that the most likely source of energy for Dark Energy, is coming from photons, and gravitational time dilation shows us how it's possible for that specific process to result in an expansion of space due to photons. I should make some modifications, corrections perhaps, to my original post, but I'll leave it the way it started. Thanks for the links.

Thanks! That was interesting. Black hole powered galaxies and their streams sure put out a lot of high energy photons and other particles! Ken brown posted: http://scitechdaily.com/ultra-fast-outflows-are-common-features-of-black-hole-powered-galaxies/. Wonder what would the gravity well be like for the photons in those particle jets?

I was referring to the gravitational time dilation of photons as being behind the accelerated expansion of our universe. I believe the perceived redshifted photons are the result of the stretched space from the gravitational time dilation process, even out in deep intergalactic space.

Could the source of Dark Energy be light?
Thank you Ed Schulte! Yes, it really does make an awful lot of sense. Light has constantly been being created since the Big Bang, and has been bleeding energy into the fabric of space ever since. Dark Energy has been increasing along with light production. The connection really seems undeniable! What follows is also interesting to consider: In keeping with Occam's razor, we have 4 forces that could explain dark energy. It can't be the nuclear forces, and it's not likely gravity. Therefore it must be electromagnetic. If light would be powering Dark Energy, then it must be electromagnetic in nature.
