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

I think this is predicated on the assumption that a portal acts as if it’s anchored the same way a bell is to a rocket engine.
I don’t think it is. Does anything in the games show a portal imparting thrust onto the wall/object it’s mounted on? I don’t think so. I think portals can’t be used for thrust.
It’s also pretty clear to me that transfer through a portal is instantaneous, not limited to lightspeed. You can hang out/change direction halfway through a portal as much as you want.
