Abstract

Our universe supports life because of some rather remarkable coincidences. If the values of the physical constants that govern the fundamental forces and interactions in our universe were just a bit different, then life (or at least, life as we know it) would be impossible. I devoted a previous column (“The ‘Real World’ and The Standard Model”, Analog, May 1996) to a discussion of some of the consequences of tinkering with some of the physical constants, but let me give some further examples here.
