Are questions without answers worthless?
No, questions without answers are not worthless. I perceive there are two categories of these questions: (1) There will be questions which cannot be answered affirmatively simply because we do not have admissible evidence or proof. This is good because man does not have all the answers to all the questions. (2) There may be questions whose answers may be slow in coming and therefore are without immediate response. Patience is much needed for the answers.
