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. When these hit you, the electromagnetic wave can cause molecules in your skin to start vibrating and you feel the effect as heat. The next increase in frequency brings us to visible light starting with red and proceeding through orange, yellow, green, blue, and violet. Even higher frequencies yield ultraviolet, x-rays, and gamma rays, all of which are invisible to the human eye.
