Query: A Regular Theory of Magnetic Monopoles and Its Implications   A regular charge-monopole theory is derived from simple and self-evident
postulates. It is shown that this theory provides explanations for effects of
strong and nuclear interactions. The theory is compared with Dirac's monopole
theory. Applications to strong and nuclear interactions are compared with
quantum chromodynamics. The results favor the regular charge-monopole theory
and indicate difficulties of the other ones. An experiment that may provide
further evidence helping to decide between the regular charge-monopole theory
and quantum chromodynamics is suggested.
