>Portals can be thought of as doors between two points in space rather than contiguous rooms.

If you want to use the old "door" analogy thing, Please see this image for the correct interpretation.

It's not just like moving a door. It's moving a door, AND ALSO MOVING THE ENTIRE REALITY BEHIND THAT DOOR TOO. See image.

>inb4 what if the portal stops
I have an image for this, too.

This is an important problem, and you bring up a good point.

Here is the door analogy as I see it:

You aren't just throwing a door, you are throwing a door and the entire reality behind that door too.

It would be like having a cube floating above a train track in space. A train is headed right for the cube, and there is an open door on one side of the train.

The train moves along the track, the door goes around the cube. See image. Now, the cube is still standing still as far as it's concerned. But from the perspective of someone on the train, the cube appears to be rocketing toward the back of the train.
