In Portal, using the portal gun to get to the moon is the obvious space travel usage, but I think people are overlooking how it'd let you trivially break the rocket equation. (digipres.club)

Hell, you could build a >1g torchship using nothing but the ocean.

@[email protected] My first thought was the Stargate thing where the effects go through the portal, but they didn't have the other in a black hole, just near it.

Would that make the portal one-way? Would it allow things to escape the event horizon? Would a portal even be able to go into one? What makes a surface capable of holding a portal? Would those properties cease in a black hole? Interesting questions.
