The disclosure movement is a social movement that argues in favor of various conspiracy theories which allege that governments generally, or the United States government specifically, have secret information regarding UFOs and "non-human intelligence" – variously described as space aliens; "interdimensional" beings; beings originating on Earth or native to the atmosphere; demons; and even time travelers. The movement advocates for the supposed information to be declassified for purposes of human, social, and scientific advancement. The disclosure movement prophesizes a future event or process called "disclosure" that will mark the date upon which such declassification occurs.
