  Based on the proposal that the Skyrme theory is a theory of monopole we
provide a new interpretation of Skyrme theory, that the theory can also be
viewed as an effective theory of strong interaction which is dual to QCD, where
the monopoles (not the quarks) are confined through the Meissner effect. This
dual picture leads us to predict the existence of a topological glueball in
QCD, a chromoelectric knot which is dual to the chromomagnetic Faddeev-Niemi
knot in Skyrme theory, whose mass and decay width are estimated to be around
$60 GeV$ and $8 GeV$. As importantly, the existence of the magnetic vortex and
the magnetic vortex ring in Skyrme theory strongly indicates that the theory
could also be interpreted to describe a very interesting low energy condensed
matter physics in a completely different environment. These new interpretations
of Skyrme theory puts the theory in a totally new perspective.
