Thinking about prime quaruplets. (Four primes of the form 10n+1, 10n+3,10n+7,10n+9). Like 11,13,17,19. Or 101,103,107,109. Or 191,193,197,199. Or 13001,13003,13007,13009. There's no telling when they show up. If somebody has a super-computer, they need to check to see if n=2 is not the only n for which 2 x 10n - 1, 2 x 10n -3, 2 x 10n - 7, and 2 x 10n - 9 are all prime. n = 3 doesn't work because 1991 = 11 X 181. n = 4 doesn't work because 19999 = 7 x 2857. And if such an n were found, then what? A hymn book with 2 x 10n hymns in it? And if somebody's weight varied according to the number of the hymn being sung? But if they stayed the same volume, that might make the church have a black hole in it, at times. Because, people might very well come to weigh as much if not more than the earth, and I've heard it said that, if the earth could be reduced to the size of a golf ball, it would become a black hole. Imagine: just as the organist was doing the opening chords of the hymn, a black hole opened up! And if the hymns for the service consisted precisely of numbers 191, 193, 197, 199, would anybody pick up on what a mystery that was? And if the church got a new hymn book with the hymns numbered differently, wouldn't they be surprised if people's faith got shattered! Even worse than evolution... Old believers might be seeking refuge in hymn 739, after gulping down the communion wine, but having that nearly break the floor of the church, and somebody's having to be resigned to weighing 739 pounds for the rest of the week. And 739 is a prime number, too. Wild.
