- For starters, you are being way too logical. It goes like this:
- monopoles would explain charge quantization, which is otherwise
- not easy to explain. So let's look for monopoles!
-
- Yes, of course there might be just ONE monopole. For all we know, that's
- what they saw in that mysterious irreproducible experiment - the one
- and only monopole! But it goes against the grain in particle physics
- to have particles that there's just ONE of. If there were "unique" particles
- floating around it would be hard to discover universal laws, so we
- optimistically assume there aren't.
