I have always been intrigued by the question: does infinity physically exist? My attempts to create infinity by cutting the dice up into infinitely small pieces ran aground when I hit indivisible quarks. It even seems that I can’t divide space infinitely often, since space may be quantized. So my quest to know if infinity exists will turn in a different direction: I shall look out, not in. What happens if I keep going in a straight line? Do I go on forever? It is a question that I think everyone who looks up into space must contemplate at some point in their lives.
