Question

What type of questions cannot be solved by scientific methods?

Answer 1

Scientific method is a continuous process. This process starts with the observation of a certain phenomenon. Based on what is observed, a hypothesis is develop to describe this phenomenon. This hypothesis is then tested by experiments where the results of these experiments either confirm or contradict the developed hypothesis.
If the hypothesis is contradicted by the results of the experiment, then another hypothesis is developed and tested for either confirmation or contradiction.

Based on this, any question that cannot be tested and studied experimentally cannot be solved using scientific methods.
