Explanation:

Science is in fact limited to topics in which evidence can be gained through experiments and/or observations.

This happens because to realize science, scientists have to strictly follow the scientific method. And in this method, essential steps are observation, formulation of hypothesis and experimentation.

It is also important to note that not all knowledge can be covered by the scientific method, this does not mean that it is not valid, just that it is not science.
