Query: Real-time dynamics of proton decay   Substituting Skyrmion for nucleon, one can potentially see -- in real time --
how the monopole is catalysing the proton (or neutron) decay, and even obtain a
plausible estimate for catalysis cross-section. Here we discuss the key aspects
of a practical implementation of such approach and demonstrate how one can
overcome the main technical problems: Gauss constraint violation and
reflections at the boundaries.
