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] Yes, but if everyone built 1g torchships pretty soon there'd be no oceans! Much better to use Jupiter instead: nobody will miss it, right?

@[email protected] yeah!
Or there's that possibility that Europa has more ocean water than earth, why not drain that? You can get there pretty easy with a torch ship...

Or hell, with free thrust let's just deorbit all the comets in the oort cloud into Mars and use the new Barsoom Ocean as our remass.

@[email protected] (I did think about jupiter more seriously but the problem is that you'd have to build a structure that could withstand the pressures of Jupiter's atmosphere as it falls into the planet. That's way harder than something that can survive the earth's oceans, even if you would get more thrust out of it)

@[email protected] @[email protected] Why not just open a portal into the Sun?
