I thought one day that Newton found that the gravitational acceleration is 9.81m/s^2 down and used that as a constant before he discovered or claimed Fg= GMm/r^2. As far as I know G is a constant today too. would it be correct to say that as long as there are constants we lack in the knowledge of that particular area of study?
