Light has incredible energy, which you can feel on your skin when you are sunbathing. Light zooms at amazing speeds across the Universe. When planet Earth was formed, its light came from the sun, stars and lightning flashes. Millions of years later, humans have found many different ways of making light. Lasers are used in almost every part of life on our planet.
Some lasers are billions of times more powerful than a light bulb.
