| Jan 3, 2019 at 17:58 | comment | added | The Coding Wombat | @BenCrowell I added a detail to the argument about running into each other. I also think he's talking about two or more light rays already at the event horizon and collide at a later time if they don't run parallel. So not about light rays from outside the event horizon hitting light rays exactly on the event horizon. | |

Elaborated on argument
