How do you turn a sphere inside out? - Answers

To turn a sphere inside out, a process called "sphere eversion" is performed. This involves smoothly deforming the sphere without tearing or creating any edges, allowing the inside of the sphere to become the outside. Mathematically, this can be achieved using advanced techniques from topology, such as the use of a "cross-cap" or other methods that involve folding and bending the sphere in three-dimensional space. It's a fascinating concept in topology that challenges our intuitive understanding of shape and space.
