... To sum it up, light travels very quickly. Indeed, astronomers use light to measure distances. A light year is defined as the distance that light travels in one year. This is equal to 9,460,528,400,000,000 (nine quadrillion, 460 trillion, 528 billion, 400 million) meters! Gosh! Taking this even furth ...
