WebIt is known as "Sphere Eversion" and is a common thought experiment in topology. The experiment was first posted in 1957 but was later made more real via computer generated graphics coming around in the 1980-1990s. It is notable for only being possible while using an entire sphere, as it is impossible while using a ring. Websphere into three-space is regularly homotopic to the antipodal embedding. This is equivalent to say-ing that the sphere can be everted, or turned inside out. However, construct-ing a sphere eversion fol-lowing the arguments in Smale’s paper seemed to be too complicated.
