Physics, Astronomy & Cosmology / Can fundamental constants vary?

Do physicists understand what constants are in the mathematical sense? constants are numbers added to a function containing one or more known variables that results in the production of a result. Constants represent unknown factors that apparently don't change sufficiently to be detected. These factors could be variables that only change slowly or in which the change is so small that existing equipment lacks sufficient sensitivity to detect the change.
