DO NOT listen to ANY IDIOT that says this quote. Extraordinary claims require FIVE-SIGMA evidence, that's THE SAME as any other claim!! Earth goes around the sun? Only telescopes were used to do that, nothing extraordinary! Heat isn't phlogiston? It was just by boring cannons! ORDINARY 5 SIGMA EVIDENCE, like what we have for the Higgs boson! EVIDENCE IS EVIDENCE!! It does NOT come in "shades of ordinariness", because ALL EVIDENCE IS CREATED EQUAL!! And it is persuasive when it is persuasive, that is, when it is direct 5-sigma evidence for.
