@futurebird If the fine structure constant is fine-tuned, we can appeal to anthropics (or multiverses even?) and say a particular fine structure constant was necessary for intelligent observers to arise and measure a fine structure constant. The moon and sun having similar arc sizes? Has to be a coincidence. BUT IT'S SUCH A WEIRD COINCIDENCE. Why would the only known self-reflecting intelligent species in the universe HAPPEN to pop up in the exact slice of time and space for Good Eclipses. Why!!
