A hypercritical value for the magnetic field is determined which provides the full compensation of the positronium rest mass by the binding energy in the maximum-symmetry state and disappearance of the energy gap separating the electron-positron system from the vacuum. The compensation becomes possible owing to the falling-to-the-center phenomenon. The structure of the vacuum is described in terms of strongly localized states of tightly mutually bound (or confined) pairs. Their delocalization for a still higher magnetic field, capable of screening its further growth, is discussed.
