The Bogdanov affair was an academic dispute regarding the legitimacy of obtaining Ph.D. degrees by French twins Igor and Grichka Bogdanov and a series of theoretical physics papers written by them in order to obtain degrees. The papers were published in reputable scientific journals, and were alleged by their authors to culminate in a theory for describing what occurred before and at the Big Bang.
