Right !  His guess is a hypothesis.  It may be right, and it may be wrong.  

A hypothesis has to be TESTED by experimenting.  If you do one or two  experiments to test your hypothesis, and the results of the experiments look like they confirm/support the hypothesis, THEN you've got yourself a "theory".
