Where do you find a wormhole?

Excuse me, could you possibly enlighten me on the topic of wormholes? I'm quite fascinated by the concept and was wondering where one might actually locate such a mysterious phenomenon. Do wormholes exist in our physical universe, or are they merely theoretical constructs? If they are indeed real, where might I begin my search? Perhaps there are certain regions of space or specific conditions that increase the likelihood of encountering a wormhole. I'd appreciate any information you could provide on this intriguing subject.
