fringe theory
Marginal scientific speculation
A fringe theory is a hypothesis or belief system that exists outside mainstream scientific or academic consensus.
Fringe theories range from plausible but unproven ideas to outright pseudoscience: Supporters of the fringe theory claimed the pyramids were built by aliens.
The term implies marginality without necessarily judging validity—some fringe theories eventually gain acceptance, though most don't.
