I'm getting a bit confused.

To put it in a nutshell, the essence of it is the following. If a three-dimensional surface is reminiscent of a sphere, then it can be spread into a sphere. It is known as the Formula of the Universe because it is highly important in researching complicated physical processes in the theory of creation. The Poincare conjecture also gives an answer to the question about the shape of the Universe.

But doesn't Buckmeister Fuller say that the Universe is a triangle? and I think that circles are not natural to the environment?
