fringe theories
Ideas lacking consensus
Fringe theories are ideas that exist outside mainstream acceptance in a field—explanations that most experts reject or consider unproven.
The term often appears in discussions of science, history, or medicine: flat earth beliefs, ancient astronaut theories, claims that vaccines cause autism.
Fringe carries a dismissive connotation, suggesting the theory lacks credible evidence or methodology.
Proponents sometimes prefer "alternative" or "unconventional."
