Monolith

From V3Pedia

The Monolith is a black rectangle that has the ability to seemingly do anything via dimensional shifts. When the space eel plugged the 5-light year long extension cord into the monolith it caused the entire solar system to end up inside the Monolith. Since then another Monolith has show up on the Gas Giant's moon, which when Morty called defective also caused the entire solar system including the other Monolith to be inside it.
