Does scientist can answer all of the question that can be asked?

Answer 1

No where in the world can one or a group of scientists answer all possible questions that can be asked. First, someone needs to think of good questions to ask and form hypotheses. Second, many things have not even been thought of to ask---yet.

Science answers simple questions of the nature if-then. Mathematically, however, it can be shown that we can't answer all the questions that can be asked.
