Interesting precision, I have to say. My note began "Well, we will study, study, study..." as I know science does not bring answers to every question. In fact, it seems in the nature of science to encounter unexpected issues while studying a particular problem. These issues will often lead the original study to failure to bring consistent conclusions. The researchers will then positively see them as further questions requiring to be studied.Science is the only discipline that readily admits it doesn't understand everything. You may be confusing it with marketing.
