One question that scientists cannot yet answer is the cure for cancer. They cannot find a cure mainly because cancer is not a single disease; it’s a loose group of any hundreds of diseases. Not every cancer cell is the same so there are multiple levels of difficulty. Other reason scientists cannot yet cure cancer is because they are limited of recourses because of the lack of funding, if they had enough funding to research more into this disease.
Another question that science is still trying to answer is the cure for hiv/aids. The main reason that scientists have not been able to cure this disease yet is because they don’t have the level of technology to do that yet. They can only alter a few cells a day but the human body consists of trillions of cells. Therefore until they discover technology to this level the chances of finding a cure for hiv/aids is very low.
Research 2 examples of questions that science will probably never be able to answer

A question that science cannot answer is how life began on earth. Scientists cannot be certain as to how life began mainly because no one was around at that time to be certain what happened so scientists have to just make educated guesses based on the evidence they can find from the beginning of the planet. Most of this is microscopic since it is strongly believed among scientists
