Abstract

The idea whether fundamental constants vary with time was discussed. Today, atomic physics, nuclear physics, and cosmology enable physicists to probe changes in the fine-structure constant over time scales ranging from a few years to nearly the age of the universe. Most physicists take for granted the constancy of fundamental physical constants. However, whether those constants change with time is not just a philosophical question - it can be discussed in plausible theoretical frameworks.
