No, a scientific question should not be vague, non-testable, or non-repeating. A scientific question should be specific, testable, and repeatable in order to be investigated and answered using scientific methods.

Here are the characteristics of a good scientific question:

1. Specific: The question should be clear and focused, addressing a particular aspect or phenomenon.

2. Testable: The question should be able to be answered through observations or experiments. It should be possible to design a study or gather data to test the question.

3. Repeatable: The question should be able to be replicated by other researchers to ensure the reliability of the results.

4. Creative: While a scientific question should be based on existing knowledge and evidence, it should also involve some creative thinking to push the boundaries of current understanding.

In summary, a good scientific question should be specific, testable, repeatable, and ideally have some element of creativity.
