Research always implies not knowing... If it's already known, there is no need to research it.
However, it also implies wanting to know. The consequence of your comment seems to be that we should not research because we will never know and that goes against the entire body of knowledge collected by Humanity over the last 10,000 years.
So you're the kind of guy who admits he doesn't know, and then doesn't do anything about it. That's fine.
But there are people who readily admit they don't know, but will do research to find a solution. You're not in that category - that's okay - but at least realize that most entrepreneurs/hackers are in the latter camp.
