Recent verifications of a new relativity principle and a new   gravitational theory based on properties of light
  Recent astronomical observations verify the new scenario resulting from new conservation laws and a new relativity principle fixed either by dual properties of light or by new gravitational (G) tests and the Einstein's equivalence principle. This scenario is radically different from the classical one. During a free fall, the relative masses of free bodies, with respect to the observer at rest in a G field, remain constants. The energy released during the stops in different G potentials (GP) comes not from the G field but from the bodies. The relative properties of the bodies at rest with respect to the observer depend on the differences of GP between the bodies and the observer. The increase of GP due to universe expansion expands bodies in identical proportion. The universe age may be infinite. Its entropy is conserved because the new black hole, without singularity, after absorbing radiation, explodes regenerating new gas that transforms dark galaxies into luminous ones. Galaxies evolve, indefinitely in closed cycles with luminous and dark periods. All of their phases are found anywhere in the universe. They solve fundamental dilemmas like dark matter and radiation backgrounds
