Conspiracy Theories

This is a list of conspiracy theories; theories involving conspiracies, which are not recognized as true by most mainstream sources.
A conspiracy is defined by law as an agreement by two or more persons to commit a crime, fraud, or other wrongful act.[1] While in the strictest sense a "conspiracy theory" is a theory about a conspiracy, the term usually refers to a theory that attributes the ultimate cause of an event or chain of events (usually political, social, pop cultural or historical events), or the concealment of such causes from public knowledge, to a secret, and often deceptive plot by a cabal of powerful or influential people or organizations.
This list of conspiracy theories is a list of some of the most prevalent conspiracy theories which have not been recognized as true by most mainstream academics. In some cases, rebuttals have been offered to counter the theories; in other cases the theories have merely been summarily dismissed.
