Gabfly1, you are not asking the right question 
First of all, what difference would it make what everyone believes. You should have formulated the question as "Is it possible to predict how far....?"
Even if that was the question, it would still have a very simple answer "NO". Because no one can predict anything.
Think again about the question you want to ask and you may actually get some useful answers
