Fundamental Physical Constants

Fundamental physical constants are universal numbers that describe basic properties of nature, remaining the same everywhere and at all times. Examples include the speed of light (how fast light travels), the gravitational constant (the strength of gravity), and the charge of an electron (the basic unit of electric charge). These constants underpin the laws of physics, allowing scientists to understand and predict phenomena across the universe. They are like the universe's foundational settings, essential for exploring everything from gravity to quantum mechanics. Their stability and precise measurement are crucial for advancing scientific knowledge.
