Lunar Inspiration

My son had just gone to bed and called me Dad come here and I went in thinking he wanted some water but he was standing by the window gazing up and without looking at me he said Dad look at the moon it has a hole in it and I said what and looked up at the moon which was full and bright filling his room with a chalky light and sure enough there was a tiny hole towards the bottom and to the left. Well how about that I thought was that always there and I just never noticed it or is it something new a thought I'm having more often these days but my son was thinking about something else: Dad he said is that hole like the missing scale in the neck of Smaug the Dragon or the thermal exhaust port on the Death Star and if someone fires an arrow or a proton torpedo straight into the hole the moon will blow up? Well I hardly think so I said it's probably just a trick of light making a shadow that looks like a hole but it isn't really a hole like when they found a face on Mars that turned out to be nothing but shadows. Are you sure he asked; sure I'm sure I said. Okay he said and climbed into bed confident that the moon was in no imminent danger. I didn't share his relief and watched the moon thinking the hole might go away but it became a bit more prominent and it hit me there must be people all over the world watching this getting all sorts of crazy ideas.
