Well, I certainly was befuddled...I found this:
In physics, a magnetic monopole is a magnet with only one pole. In other words, it would have net magnetic charge. But magnetic monopoles have never been observed or created experimentally. When a magnet with a north and south pole is cut in half, it becomes two magnets, each with its own north and south poles. There doesn't seem to be a way to create a magnet with only one pole. Yet particle theories like Grand Unified Theories and superstring theory predict the existence magnetic monopoles.

(Ack, I just reread that--they did leave out a word.)

So, Mr. Faldage, were you saying that good without evil is as impossible (theoretically) as a monopole? I think it's kind of fun to think of this apparent paradox with ref. to a deity (any deity, Mr. Ectoplasm; I for one didn't take your post to mean you were promoting anything in particular); the old type of question such as can God create something so large he can't move it--that sort of thing.
Bean, can you, as our resident physics expert, shed any light on the possibility of a monopole?
