The basic idea of DGIT is just to accept a simple assumption: Gravity is not limited to a central force, but also has a local dynamic inductive influence (DGI). The stiffness and the adherence of the Space-Time Continuum are the consequences of DGI. In DGI's presence all the energy systems (massive or not) have the same behaviour In my opinion we choose to believe in the existence of some alleged Dark Matter, distributed exactly where we need it for confirming our equations. If it really exists, let it be It will definitely become obvious when the Universe will decide. I agree: it might seem unexciting to use the same old equations as Newton did, and incommodious to suggest adjustments to Einstein's field equations. Well, I'm not a well-known physicist, and I'd rather have a plain explanation than a complicated theory.
