The nature of supernova explosion and their governing physics have still remained very poorly understood. The current explanation of this astronomical phenomenon is based on the hydrodynamics with a shock or convection driven by neutrinos that are generated from nuclear reactions of heavy nuclei such as carbon in the core of star. Its success, however, crucially depends on the cross section for neutrino capture on and scattering off nucleons and nuclei, the neutrino production rate, and the neutrino convection behind the stalled shock. In this presentation, a new mechanism called gravitational field shielding is proposed for supernova explosion in accord with a five-dimensional fully covariant Kaluza-Klein theory with a scalar field, which unifies the four-dimensional Einsteinian general relativity and Maxwellian electromagnetic theory. It is shown that a dense compact core of a star will suddenly turn off or completely shield its gravitational field at the core surface when the core collapses to a critical density, which is inversely proportional to the square of mass of the core. This gravitational field shielding can lead a supernova to impulsively explode its outer material or mantle and form a compact object as a remnant such as a neutron star. This works like that a compressed spring will shoot its oscillator when the compressed force is suddenly removed.
