The beta decay is the second grand Cosmic event of the Universe and is interpreted by the increased cohesive pressure, by the electric entity of the macroscopically neutral neutron and by the inductive-inertial phenomenon. It is a new interpretation of E/M and weak nuclear forces. Their integration with the strong nuclear and gravitational force is achieved with the unified field of the dynamic space, which is identical with the Higgs field, while the homonymous boson is located in the core of the particles and in black holes as space holes after the collapse of the stellar matter. The unconfirmed results (found from the team of the Fermilab Accelerator), that the W boson is more massive, suggest deviations from the Standard Model and come possibly as a result of an as yet undiscovered fifth force of Nature, are no longer needed to be interpreted or justified.
