I was once challenged if there was any possible way to view an event in the past without any means or recording it during the event. I pondered for a while and said that it was possible. I asked this student of mine to stay after sunset and after finishing the days’ work, I took him to the roof and showed him the stars. He wasn’t that impressed. I explained to him that what he is staring at is the answer to his doubt. The stars we are witnessing are not at real time. We all have studied that these stars we view are several billion light years away. We are also taught that light is the fastest object in the universe and we can only see things of which light has reflected from. What this means is we are actually witnessing the stars as they were several billions of years ago. The light from these stars have travelled several billions of years to reach us and we are witnessing an event that has already happened.
