When the universe came into being, all was light. Matter condensed from this energy forming the galaxies, stars, and planets that we study today. Light from the Sun supplies the Earth with all its energy. The energy we use in the form of electricity, and fossil fuels can all trace their origins to light energy from the Sun. The energy we derive from the food we eat, the energy of life, was all originally light.
Nothing moves faster.
Consider for a moment that light can travel around the Earth more than seven times in one second. It took the Apollo astronauts three days to reach the moon - it takes light about a second and a half to cover the same distance. Light is made by wiggling electric charges. Whenever an electric charge wiggles, light is given off. Faster yet and you produce infrared waves.
