Query: Monopoles as Big as a Universe   We show that, contrary to the standard belief, primordial monopoles expand
exponentially during inflation in the new inflationary universe scenario.
Moreover, inflation of monopoles continues without an end even when inflation
ends in the surrounding space. Therefore primordial monopoles (as well as other
topological defects produced during inflation) can serve as seeds for the
process of eternal self-reproduction of inflationary universe.
