Because we all love a flaming cow story: De Groene Amsterdammer (a Dutch newspaper): A Dutch veterinarian was fined 600 guilders [about $240USD] for causing a fire that destroyed a farm in Lichten Vourde, the Netherlands. The vet had been trying to convince a farmer that his cow was passing flatulent gas; to demonstrate, the vet ignited the gas, but the cow became a 'four-legged flame-thrower' and ran wild, setting fire to bales of hay. Damage to the farm was assessed at $80,000USD.The cow was unharmed. You gotta love a Dutch veterinarian.
The universe, by definition, is infinite. It is arrogant for us to think mankind can formulate all the questions much less grasp all the answers.
