The following is a list of notable unsolved problems grouped into broad areas of physics. [1]Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.
Igor Bogdanov (left) and Grichka Bogdanov (right) in 2016. The Bogdanov affair was an academic dispute over the legitimacy of the doctoral degrees obtained by French twins Igor and Grichka Bogdanov [1] (usually spelled Bogdanoff in French language publications) and a series of theoretical physics papers written by them in order to obtain degrees.
