Dudes. Seriously. Go read some Lovecraft and stop harshing our sci-fi mellow. Like half of every Lovecraft story ever involved angles that JUST. WEREN'T. RIGHT. Because it's, you know, scary. And I've seen sci-fi stories before that involve pi being damn weird in Wrong patches of space. Even a gradient on the value of pi.
I've always wanted to try and make some computer simulation of what wrong space would look like. It's not THAT hard to imagine...like, let's say you have a little shed in a field in the middle of a patch of wrong space. Now cut out a chunk of the circle, including a chunk of the shed and make it portalicious so that if you look at where the chunk was cut out, you see through the other side of the chunk. You could have a shed with only three walls, each ninety degrees, but you have to walk 360 degrees around it in real-space to get back where you started. It'll seem like the barn is almost rotating along with you, because it turns at a lower speed than everything else in your reference frame... Of course, it's tricky to make the ground in wrong space match up with the ground in real space.
But if you could pull that off in a game, and keep it subtle--like, only snipping out 1/16th of a circle? Suddenly the player knows that SOMETHING is wrong, but it's really, really hard to pin down exactly what it is. Like, that tower off in the distance, it's almost like it's watching you...it seems to be facing you a little bit more than it should...Is it turning? Are all the mountains turning around you?
Uhh, that was pretty off-topic. But the observable universe is not infinite by any stretch of the imagination. If you start looking into other weird things like the concept of a holographic universe, or...whatever the latest buzzwords are, then sure, maybe we live in a multiverse where everything of a nonzero probability is possible and therefore guaranteed. Me, I find that horrifying...and I think that the Fermi paradox is on my side when I say that none of those infinite possibilities have any way of touching us here on earth, or they already would have.
