Often, simply learning and implementing information is not enough. Everything is a type of model designed by humans. Some are more accurate at quantifying and scaling various scenarios than others. It also depends on the type of model we plan, select for our coverage of particular solutions to a problem. Problem-solving is important but so is knowing to ask the right questions, making enough judgements on elements weakness. Above all, making information easily accessible to others. These can include simplifying a problem, making concise data to be read by everyone and come up with interesting topics. Knowledge is to be shared with everyone. The type of hidden knowledge is not understood and is often intertwined with pseudo-sciences. We don't get proper understanding of the past as we forget it, the multitude of present instances and the future. We also don't completely understand the complete idea and scenario of human existence and the concept of multiverses. The study of black holes, worm holes can also be a type of hidden knowledge because we have no physical evidence or feel of them. Even though gravitational lensing is used but yet it unclear how actually a black hole looks in clear definition.
