I've seen several references to EA and how it might explain sunsets. In the wiki, there is an equation that purports to show the effect of "decreasing dark energy" on a light ray. Best I can surmise is that the light ray will bend towards the "fastest decreasing Dark Energy potential" - correct me if I'm wrong.
From the Wiki:
x, y - co-ordinates in the plane of the light ray, where y is increasing in the direction of fastest decreasing Dark Energy potential, and x is increasing in the direction of the component of propagation of the ray which is perpendicular to y.
c - the speed of light in a vacuum.
β - the Bishop constant, named in honour of the great Flat Earth zetetic Dr. Tom Bishop, which defines the magnitude of the acceleration on a horizontal light ray due to Dark Energy. When the theory is complete, attempts will be made to measure this experimentally.
A few very obvious questions come from this - hoping one of the more astute FEers can tackle this.
1) What experiments have been performed to quantify the changes in the dark energy potential?
2) How does DE affect light's path?
3) The Bishop constant...what is the theoretical value?
As an aside - Tom, I didn't know you held a doctoral degree! What was your field of study?
