HOW MANY MILES ARE THERE IN A LIGHT YEAR? HOW MANY LIGHT YEARS WOULD IT TAKE A RAY OF LIGHT TO MOVE FROM ONE SIDE OF THE UNIVERSE TO THE OTHER?

A light year is equal to almost 6-trillion miles. While the universe is considered infinite, our galaxy, the Milky Way, is estimated to be more than 100,000 light years in diameter. Therefore, a ray of light would need at least 100,000 years to travel from one side to the other..
