= Time-variation of fundamental constants
{wiki=Time-variation_of_fundamental_constants}
The concept of time-variation of fundamental constants pertains to the idea that certain physical constants—such as the speed of light (c), the gravitational constant (G), the Planck constant (h), or the fine-structure constant (α)—may not be truly constant but could vary over time. These constants are considered to be the foundational building blocks of our understanding of physics and the laws governing the universe. \#\#\# Key Points about Time-Variation of Fundamental Constants 1.
