Webb2 maj 2001 · Joseph Silk. No. We do not know whether the Universe is finite or not. To give you an example, imagine the geometry of the Universe in two dimensions as a plane. It is flat, and a plane is normally infinite. But you can take a sheet of paper [an 'infinite' sheet of paper] and you can roll it up and make a cylinder, and you can roll the cylinder ...

Webb2 apr. 2015 · The size, shape, and stiffness work well for three-dimensional projects. And they are easy to fold. “The ratio of the sides of an American business card is 1.75:1. But 1.75 is very close to the square root of 3 (1.732) which is the arctangent of 60 degrees. This means that it is very easy to fold equilateral triangles in a business card. WebbThere are probably many ways of defining a shape with infinite perimeter enclosing a finite area, but here are 3: (1) The Koch snowflake, which is a fractal curve.
