A new method for studying astrophysics is now yielding fascinating results. Instead of mindlessly accepting existing constructs that are untestable by definition (e.g., dark matter, dark energy, etc.), this new method is based entirely on laboratory physics. It solves problems that have defied previous efforts by integrating all of the provable forces into non-linear systems, where competing forces cause instabilities that resolve into the distinctive forms that we observe. Existing theories acknowledge only inertia and gravity, and if those forces can't fully explain something, the theorists account for the discrepancies with untestable inventions. The new method acknowledges inertia, gravity, electromagnetism, and nuclear forces, and demonstrates that the resulting combinatorial complexity can plausibly resolve into a wide variety of forms. When two or more configurations of forces appear to match the explanandum, additional data are tested against the expectations of each configuration. In the end, this method settles on the most probable combination of known forces, given the available data. And nothing within the problem domain has been found to necessitate the invention of anything new.
