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] Now this is bugging me too. If you actually wanted to loop a falling object between two portals and forget about it, would it have to be at one of the Earth's poles? I feel as though otherwise the object would start to drift out from between the two portals due to the Coriolis effect (ignoring the fact that an object left falling like this at the equator would constantly be cancelling out whatever effect it produced 12 hours previously).
