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] @[email protected] A portal gun (with the other end of the portal inside the photosphere of a blue-white supergiant) makes a really neat blaster!

@[email protected] @[email protected] @[email protected] Backblast might make it a weapon of last resort, though.

@[email protected] @[email protected] @[email protected] true, but the fun part of a portal-ship is that there's really no difference between a crewed lander and a remote-controlled doomsday missile.

if you land somewhere uninhabited and/or friendly, you can drop a portal and then send people through. if it's unfriendly, you open the supergiant portal, and have the portal gun throw itself through a return-home portal that instantly closes. you build another ship
