A Grand Unified Theory is a model in particle physics in which at ultra-high energy, the 3 gauge interactions of the Standard Model (electromagnetic, weak, and strong) merge into a single one, characterized by one larger encompassing gauge symmetry and one unified coupling constant. After SSBreaking, force carriers differentiate themselves and are driven by the RG to their values and numbers in the lab. Use for gauge GUT and gravity unification.

Why do physicists believe that there exist magnetic monopoles?
I'd be interested to know who told you such a thing. I gather that the existence of magnetic monopoles is a natural consequence of many (most? all?) grand unified theories, so that's probably what who …
