What is a wormhole in pokemon go?

In Pokémon GO, a wormhole is a feature that allows players to enter different dimensions called Ultra Space. Players can access wormholes by using special items called "Ultrapasses" which can be obtained by completing special research tasks or participating in events.

In Ultra Space, players have the opportunity to encounter rare and powerful Pokémon that are not typically found in the game. The Pokémon that spawn in Ultra Space may have unique movesets or abilities that make them more powerful in battles.

Players can also complete challenges and tasks in Ultra Space to earn rewards and increase their chances of encountering rare Pokémon. Overall, wormholes in Pokémon GO offer a unique and exciting gaming experience for players looking to discover new and powerful Pokémon.
