Say you're 100,000,000,000,000 miles away from an object you are looking at. If you do that calculation: 100,000,000,000,000 miles / 670,616,629 miles per hour = 149,116 hours. The light you see from that distance took 149,116 hours to reach you, so what you see is 149,116 hours in the past.</p></blockquote><p></p>
