Can you ELI5 this notion of a FALL or even what affine geometry is broadly speaking? That's where the author completely lost me.
Not really sure about it, but as I understand it, affine geometry can be translated as linear geometry. Think euclid geometry in a 2d plane. In this black hole, I think it means that a particule behind the event horizon will go straight to the center. So every trajectory behind the hoziron is a line that goes to the center, and this center is the singularity.
