I had a character in a Star Trek role-playing game named Alex Freeman who was often involved in time travel. That's where AF and TT come from. The number 47 is a joke among the writers of Star Trek: The Next Generation, Stat Trek: Deep Space Nine and Star Trek: Voyager. They put the number or results of mathematical operations on everywhere throughout those three series. Combining all that is my username. It's useful because it is almost guaranteed to be available everywhere.
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
