MasterK:
Have no idea what your proficiency in "doing calculations" might be... though apparently BentheMan pins his burgoning sense of "being one" on his ability to "do them." Regardless, calculations divorced from a heuristic (even artistic) appreciation for both the beauty and the short-comings of physical theory amount to sissors in the hands of a clumsy child... the child can do productive work with them, yet needs constant supervision. If the child should start carving on the furnuture with them, s(he) could use a spanking... or at least a "come to Jesus" meeting, as my agnostic dad would describe such confrontations I had with him as a narcissitic child.
Anyhow, should you choose to continue exposing what seems a bright and open mind here, you might consider taking some of what people have to say with a few grains of salt. And though I may very well be mistaken in much that has been said, I still appreciate the logical open mindedness with which you question current "explanations" of dark matter.
