- scatters 6y agoObviously it has to pass through itself. The interesting thing is that it is possible to evert it without pinching or creasing.
- pja 6y agoYes, that’s why you can’t do it in 3 dimensions (without self-intersection) - if you have an extra dimension to hand you can invert the sphere using the extra dimension to avoid self-intersection I believe.
- cevn 6y agoThanks, this confused me greatly watching the graphics, I'm no mathematician... OK if we can just push the sphere through itself then yeah I guess you can invert it...
- caconym_ 6y agoCan you do the same with a circle? (In case you didn't read the article carefully—no, you can't, and that's why this is interesting.)
