According to Einstein's theory of relativity, the speed of light is a limiting factor in defining our Universe. Because the distances are so great in our Universe, we use the speed of light to call out distances to the very edge of our observable Universe in light years, which is how far light can travel in space in one year at a speed of 186,000 miles per second—this amounts to about 5.6 trillion miles in one light year! This factor only allows us to see an observable Universe limited by the amount of time light has been able to travel to our eyes since the beginning of the creation of space-time! However, if you are a scientist or cosmologist who studies the Universe, you would also say that since there are no boundaries to space, there can be no defined end of space.
