The shirts and towels, they’re really crinkled and interlocked two-dimensional surfaces. Wait.It’s one-dimensional yarn, knotted up tightly. You ok? Have another.I see it clearly now. It’s everything at once, one-two-three dimensional. Just depends on how closely you look at it. Amazing, don’t you think? What if our universe was just like that?Universal Laundry Pile.[Img Src: Clipartkid]It doesn’t sound like a sober thought, but it’s got math behind it, so physicists think there might be something to it. Indeed the math piled up lately. They call it “dimensional reduction,” the idea that space on short distances has fewer than three dimensions – and it might help physicists to quantize gravity.We’ve gotten used to space with additional dimensions, rolled up so small we can’t observe them. But how do you get rid of dimensions instead? To understand how it works we first have clarify what we mean by “dimension.” We normally think about dimensions of space by picturing lines which spread from a point. How quickly the ...
