    It’s interesting because it’s highly counter-intuitive that such a thing is possible. It’s not supposed to be useful except as an example of a false intuition, which can remind us to be careful in our reasoning.

      “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

            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?
