Light is strange, sometimes dazzling, sometimes dim. It can be coloured, white or invisible. Light has incredible energy, and zooms at amazing speeds across the Universe. Most of the light on the young Planet Earth came from the Sun, starlight and lightning. Humans have now found many different ways of making light. The most amazing light source ever invented can be billions of times more powerful than a light bulb. It is called a laser.
