Hindsight
Two friends sat talking, when one said to the other:
"I love clear nights - they allow me to literally look at things past."
His friend, highly confused by this statement but feeling embarrassed, merely grunted his agreement. However, that night when he got home, he decided to research what his friend might have meant.
What did he find?

Hint
Look at the stars.Answer
Even the nearest star, Proxima Centauri, is a long distance from earth. Proxima Centauri lays 4.2 lightyears away from earth. This means that if you look up and see Proxima Centauri, the light you are actually seeing was emitted from the star over four years earlier, and therefore in a sense you are looking into the past, as you are seeing a past image of the star.Hide Hint Show Hint Hide Answer Show Answer
