When Anakin's mother exlains to Qui Gon that he had no Father and that she carried him, gave birth to him and raised him alone, she also said that she couldn't explaint what happen. What exactly does that mean? Did she get raped or was it artaficial insemination? Maybe someone can answer this. Or maybe there is no answer since it wasn't in the movie. If Anakin had such special Jedi powers, there must have been a Jedi in the equation somewhere before he was born.
