The speed of light in a vacuum is approximately **299,792,458 meters per second** (about **300,000 kilometers per second** or **186,282 miles per second**). This speed is considered a fundamental constant of nature and is denoted by the symbol **c**. It plays a crucial role in physics, particularly in the theory of relativity, and affects concepts such as time, space, and energy.
