“You know the worst part about inventing teleportation? Suddenly, you're able to travel the whole galaxy, and the first thing you learn is, you're the last guy to invent teleportation”

Portals allow travel between two different locations. Usually, these locations exist in the same dimension/universe. The only known groups that have been known to use intradimensional portal technology are the Ricks and the Galactic Federation (Interdimensional Customs in "Pilot "). Some organizations and people have knowledge of interdimensional portal technology, but it is unclear whether they possess it or not
