Here is one of his old explanation on DEF.
The Dark Energy Field is a vector field. It has a gradient that is smallest at the interaction of the atmosphere and the field, called the boundary layer. The DEF interacts with the magnetic field of the earth at this boundary layer. These vectors produce a force vector that is orthogonal to the other vectors in four dimensional space. This force vector is always normal to the boundary layer, thus providing a type of forced containment for the atmosphere.
Those forces would still produce a planar force though. They would top it off but you'd still need walls to keep the atmolayer in. I would require TheEngineer to show proof of the more in-depth applications of his theory before I'd believe any interactions of his theory with the 4'th dimension.
I believe the theory because I think it's more reasonable than believing that the ice wall holds the atmolayer. Plus, DEF comes from the DE (the mechanism behind the Earth's acceleration) due to bow shock, making it a relevant theory. The DEF is one of the effects of DE, which is as reasonable as gravitation is the effect of space-time curvature.
For RE dynamics I could disregard Einsteins dynamics and go back to Newtonian dynamics with no noticeable loss on my end. As long as I did'nt try to track mercury to 1/600th of a degree of error per year or some shit I would be fine. If it's your assertion you could do the same for FET with dark energy dynamics, fine. It's not my job to judge... I think you're wrong though. Your DEF dynamics sound fabricated, even by FET standards.
Plus, do all FE'ers think dark energy is the mechanism behind the Earth's acceleration?
