   It means that light from that galaxy has taken 11 billion years to reach us.   
   Every second light travels approximately 186,000 miles, which makes the   
   galaxy 11,000,000,000 * 186,000 * 60 * 60 * 24 * 365 miles away. I tried to   
   work it out on my calculator, but it screamed and hid behind the sofa!   
   Since the universe is expanding, it used to be closer. How close? well, one   
   as close as these two dots .. if all the theories are correct.
