For some people, an infinite sheet of paper is simpler (because it doesnt have the extra detail of edges) and easier to imagine than a regular standard-size sheet of computer paper, while for others it is evidently simpler and easier to picture the paper with edges. I'm curious to know which people find which simpler to think about. I believe this actually has something to do with science, because of Occam's razor. The timehonored Razor principle that you don't put more in the picture than you need to fit the data. If both models fit, use the one with fewer elements. (William of Ockham said it in Latin.) IOW avoid unnecessary detail. The Razor may have something to do with mathematical cosmology in particular, and how different people seem to approach it. I think there are four main possibilities. 1. You find the infinite sheet simpler and easier to imagine. 2. You find the infinite sheet simpler, but it's harder for you to imagine. 3. You find the sheet with edges simpler, but harder to imagine. 4. You find the sheet with edges both simpler and easier to imagine. I have no idea what people will say, but my guess is that in any case it won't be unanimous one way or the other. I could have put the same question about a line. Which do you find simpler to think about, an infinite line or a line segment with endpoints? But it seemed more relevant framed in terms of something 2D. I was inspired to ask because of King Ordo's thread about the universe.
