Unlike the second law, which is more like a law of logic than of physics, the first law (conservation of energy) is more a result of happenstance. According to Noether's theorem the conservation of energy exists because the laws of physics have remained the same from when our branch first existed to today, and conservation of momentum exists because physical law remains the same from one place in our branch to another place. All that is true in our branch but need not be true of the entire multiverse. John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
