Theories include: the Tu-144 tried to avoid a French Mirage chase plane which was attempting to photograph it, that changes had been made by the ground engineering team to the auto-stabilisation circuits to allow the Tu-144 to outperform Concorde in the display circuit, and that the crew were attempting a manoeuvre — to outshine Concorde — that the aircraft was not capable of.

Theories of irrational behavior include:

Theories as to the reason for the claimed change in flavor include that the secret formula has been changed to use new products not originally available to Vernor, such as high fructose corn syrup ; that it seems to have less carbonation than formerly ; and that Vernors is no longer aged four years, but three in oak barrels.

Theories on why Chrysler used the name Fargo include the imagery of open range of the American west, symbolized by the city of Fargo and the Wells-Fargo stage lines, while another theory assumes there was a play on the words " Far " and " Go ", denoting durability.

Theories explicitly identifying Hell with an experience of the divine light may go back as far as Theophanes of Nicea.

Many Grand Unified Theories ( but not Pati-Salam ) predict that the proton can decay, and if this were to be seen, details of the decay products could give hints at more aspects of the Grand Unified Theory.

In these classes of models collectively now known as minimal supergravity Grand Unification Theories ( mSUGRA GUT ), gravity mediates the breaking of SUSY through the existence of a hidden sector.

Theories that predict the formation of these structures within the observable universe ( see: inflation ) can therefore be largely ruled out.

Theories about the processes involved in adult face perception have largely come from two sources: research on normal adult face perception and the study of impairments in face perception that are caused by brain injury or neurological illness.

Theories about them have to rely on a preponderance of other evidence, which alone are not solid enough to warrant much conclusiveness.

" Theories must also meet further requirements, such as the ability to make falsifiable predictions with consistent accuracy across a broad area of scientific inquiry, and production of strong evidence in favor of the theory from multiple independent sources.

Theories are improved ( or replaced by better theories ) as more evidence is gathered, so that accuracy in prediction improves over time ; this increased accuracy corresponds to an increase in scientific knowledge.

Ronald Story published The Space Gods Revealed: A Close Look At The Theories of Erich Von Däniken in 1976, written in response to the evidence presented in Däniken's Chariots of the Gods ?.

Theories are improved as more evidence is gathered, so that accuracy in prediction improves over time.
