The status of theory and experiments on Superheavy Nuclei is reviewed.
Based with the Two-Center Shell Model, Potential Energy Surfaces are calculated. Fusion, fission, quasifission and other processes are discussed. The experimental advances are reported.
In particular time-delay during the formation of giant quasi atoms/molecules will be crucial for observing the change of the Dirac vacuum in supercritical Coulomb fields by spontaneous positron emission.
It will be shown how the various phenomena are interrelated.
