Abstract: First we present new gravitational field equations, derived under 1) the Einstein principle of general relativity (PGR), and 2) the principle of interaction dynamics (PID), which is required and is a direct consequence of the presence of dark matter and dark energy. With new field equations, we show that dark energy and dark matter are simply a property of gravity. Then we present a blackhole theorem and a theorem on the structure of the Universe, proved in a recently published paper. The blackhole theorem states that assume the validity of the Einstein theory of general relativity, then black holes are closed, innate and incompressible. For the Universe, assume the Einstein theory of general relativity, and the principle of cosmological principle that the Universe is homogeneous and isotropic, then the Universe is static, not originated from a Big-Bang, and the topological structure of the Universe is a 3D sphere. These two theorems are rigorously proved using astrophysical dynamical models coupling fluid dynamics and general relativity based on a symmetry-breaking principle. With the new blackhole theorem, we further demonstrate that both supernovae explosion and AGN jets, as well as many astronomical phenomena, are due to combined relativistic, magnetic and thermal effects: the radial temperature gradient causes vertical Benard type convection cells, and the relativistic viscous force (via electromagnetic, the weak and the strong interactions) gives rise to a huge explosive radial force near the Schwarzschild radius, leading e.g. to supernovae explosion and AGN jets. This is joint with Tian Ma.
