The light year was invented, because, at 182,000 miles/second (9,467,077,790 miles a year), it is the fastest thing in the universe. As the universe is very huge, this is more convenient than saying how many singular miles things are from each other. Ex: 2 light years instead of 18,934,155,580 miles.
