I'm not seeing how the image shows 2d space. It's just two people staring at a blue screen that may or may not be space, the caption's not helping either. There's an example at the bottom that explained it for me but it was just two lines of text out of a bazillion, hard to see if you knew where to look. I was thinking a screenshot from one of those old school arcade games would be better, like galaga.

Thanks to WMAP, we know know the universe is flat (with only a 0.5 margin of error). What does that mean for this trope, now that space is pretty much confirmed to actually two dimensional?
