This just made me realize that the example given in the article of a 3D framework of strings interacting with a 2d plane would have its own speed limit since the fastest a point created by a string could move would be the case where the string was almost parallel to the plane. It would also stretch the moving point along its axis of movement approaching infinity the closer it got to being parallel. That thought experiment seems even more profound than it initially did. I wish I knew more physics.
