scientific constants

Scientific constants are fixed values that describe essential properties of nature and remain the same across the universe. Examples include the speed of light in a vacuum (about 299,792 kilometers per second), which defines how fast light travels; the gravitational constant, which governs the strength of gravity; and the charge of an electron, fundamental to electricity. These constants enable scientists to understand, measure, and predict natural phenomena accurately. They serve as the building blocks for scientific theories and calculations, providing a common language to describe the universe’s behavior, from atomic interactions to cosmic events.
