I was thinking about the incompleteness theorem. In a book it said that say RH might be unprovable and that a Mathematician could be working on a problem that is unprovable. But, was wondering is it even worse than that.
Are there problems such that it's unprovable, but cannot be proven unprovable. So the problem wouldn't be able to be solved by a Mathematician and the Mathematician will never know if it can be solved.
