The Out of Asia theory is an obsolete scientific theory which contended that modern humans first arose in Asia.

The caloric theory is an obsolete scientific theory that heat consists of a self-repellent fluid called caloric that flows from hotter bodies to colder bodies.

Volta believed the current was the result of two different materials simply touching each other-an obsolete scientific theory known as contact tension-and not the result of chemical reactions.

The Tetrahedral hypothesis is an obsolete scientific theory attempting to explain the arrangement of the Earth's continents and oceans by referring to the geometry of a tetrahedron.
