Speed Of Light


Speed of Light is a physical constant that represents the maximum speed at which all matter and information in the universe can travel. In the context of space and astronautical engineering, the speed of light plays a crucial role in determining the limitations of space travel and communication. It is used to calculate the time it takes for spacecraft to travel to other planets and stars, and to transmit data between Earth and space probes. The speed of light is approximately 299,792,458 meters per second in a vacuum, and it is denoted by the letter 'c'.
