From a mathematical viewpoint constants may represent factors that can not be determined. The number is inserted into the equation to get an answer. Constants may represent factors that cannot be detected because instruments are not accurate enough or factors that depend on the nature, or conditions, of space in a region. For example, some regions of space might have some type of energy field that humans have not previously encountered.

Physicists sometimes refer to the speed of light as constant, but every physicist knows the speed of light is not constant. The speed varies depending upon the nature of the medium through which light is passing. Certain artificially created situations may slow light. The speed is only constant in a vacuum, but space is not a true vacuum. Regions of space contain varying amounts of dust and gas which could affect the speed of light through the region.

It is fundamantally significant to discuss about the constancy or otherwise of the various physical constants that physicists have assigned thus far. It will be nice to see physical significance of the individual constants whether the same can be measured , difficult to measure or just beyond the current experimental cazpability. It may interest the viewers to see a mss penned down in this context titled ' In constancy of the Physical Constants and the Strength of the Force-fields '. An attachment of the same is provided too
