Physical Constants

Physical constants are fundamental values that describe the properties of the universe and remain the same everywhere. Examples include the speed of light (how fast light travels), the gravitational constant (how gravity works), and the Planck constant (related to energy at tiny scales). They serve as the building blocks for scientific laws and formulas, helping us understand and predict natural phenomena. These constants are essential because they provide a consistent reference point in physics, allowing scientists worldwide to communicate and verify their findings accurately.
