physical quantity that is generally believed to be both universal in nature and constant in time
AI overview
A physical constant is a number that describes something fundamental about how the universe works, like the speed of light or the strength of gravity, and scientists believe it stays the same everywhere and throughout all time. These constants matter because they're the basic building blocks that physicists use to explain and predict how everything in nature behaves, from atoms to stars.
