Well, since I've already found what normal people respond like to this, I may as see how mappers respond:
You are in a hallway. It goes on forever, and gets larger as it goes along. There is no curvature like the earth. What do you see?
On a more journal-related note, I think I'll deticate the upcoming weekend working on Colony 42 and writing.
But what happens when you put no lights in a HL or Source map? Think like a mapper, this is an experiment to how our minds work.
'And why are you suddenly so interested in our psychology? Studying something?' No, but I wanted to see how differently mappers saw the world. Evidently not all of us see it differently.
Had the hallway not been growing (and don't tell me it's not growing after clearly stating that its increasing in height and width the further it goes), then you would be able to look down the hall until it becomes a single point in your eye. But since it is growing the further you look, I'm assuming that the rate that it's increasing is enough to negate the "point effect".
I'm curious, what did other people say when you asked them?
If the hallway is growing uniformly with your perception of depth, so that the hallway never shrinks the further down you look, then if you look perfectly straight down the middle you will not be able to perceive the hall at all. The "non-difinitive cutoff" will set in, and you will have no sense of what is in front of you. BUT if you turn or move to the side, so that you are not looking perfectly straight down the middle, then the hallway, then you will be able to see one side.

This is sort of what I mean:

Only a 2D represetation, but you get the point.
Because, for example, scientists presume that the Universe is not going forever. It's more like a sphere. If(abstractly thinking) you could go much more than the speed of light(so you could travel faster through the Universe),starting from the earth, and maintaining the same coordinates you would end up to Earth eventually.
There are strange phenomena in ourUniverse. Between 2 black holes curvatures of time may occur.
So yeah it's somewhat strange, but I think you would end up where you started.
tl;dr .....
[Edit] Of course, what you see depends on the direction that you are looking, as WC said. If you were to turn around, you'd see the ninja monkeys who were sneaking up behind you.
The balloon example is great: Think of the surface of a balloon as a 2D version of our universe. As you blow it up, the size of the universe increases, but there is never an edge.
Edit: Read everything wrong, you had the right idea to begin with. My bad.
And this is real life I'm talking about.
