I was told that at the end (of the tunnel) there will be a Gate and some prophets who administer examines, among the questions asked is "where are you from? and Where are going?" (I knew where I am from but need to know where I am going, if Tuscany and Provence are among choices - hence the need to travel) An who knows there might be physics question as "who performed the important experiment in Italy that demonstrated a fundamental building block of Newtonian theory of Gravity?" (the answer if Galileo who dropped balls from the leaning tower) LOL
