The entire universe disappears and is recreated many times a second. (Gives the appearane of motion, which is impossible in continuous reality.) There is a man who ensures that it reappears by making sure that God knows somebody cares enough to pay attention. There is always such a man, just one. If that man should die and not be replaced the universe will disappear one last time, instantly.

Nope, have not seen that before. I have heard the following, which is from a much older tradition:

Now it's said, and said truly, of the hero, Finn McCool, that if one day goes by without his name being mentioned, the world will come to an end. -- Robin Williamson

Good catch. "The druid Finegas catches the Salmon of Knowledge and gives it to him to cook. Finn burns himself while doing so and sucks his thumb, thus acquiring the gift of prophecy" The story is nearly mythical and is based on prehistoric (possibly Proto IndoEuropean) myth. It happened to a lot of people.
