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.

The only thing more Cave Johnson would be using relativistic weapons to blow up the sun

The lab boys tell me that if you dump enough iron into a star, it'll turn off. Well, we don't have that much iron on hand, but what if it's moving at 99% the speed of light?
They told me that wouldn't help, but I said pack your bags: We're doing it anyway

Portal 2 does establish that the portal-placing shot moves at the speed of light, but that just raises the question of how fast you move through the portals themselves.

It basically can't be slower than light, or you'd chop yourself in half if you moved halfway into one and then backed out.

So it has to be lightspeed: which means, if relativity is still correct, that it's also a time machine.

@[email protected] There's a Cave Jonson voice line that mentions the possibility that testing the ASHPoD may involve "trace amount of time travel".
