    “Such a thing is possible” It kind of isn’t though? It’s a sphere that can pass through itself but not be sharply creased…how are these rules not just made up?

      Specifically, the thing that exists is a regular homotopy of immersions from the standard embedding to its opposite. The “rules” aren’t supposed to be self evident, they’re part of a broader context in topology

        Hmm, standard embedding to which dimension?

            Welp, my head cannot comprehend how that is possible. How is it deforming the shape around?

            Maybe I am confusing homotopy and isotopy again.

          Yeah, basic graduate level math is a lot more useful than whatever you do with your life to warrant such an attitude.

            Oh really? Let’s try a thought experiment, shall we?

            In Universe A, let’s round up everyone with at least a master’s degree in math and shoot them.

            In Universe B, let’s round up all the mechanics and shoot them.

            Which one goes to shit faster?
