|Description=According to '''the theory rejection theorem''', a [[Theory|theory]] becomes '''rejected''' only when other theories that are incompatible with the theory become accepted. By the [[The First Law (Barseghyan-2015)|First Lawthe first law]] for theories, an accepted theory will remain remains accepted until it is replaced by other theories. By the [[The Zeroth Law Compatibility Corollary (HarderFraser-Sarwar-20152018)|Zeroth Law,the compatibility corollary]] , the elements of the [[Scientific Mosaic|scientific mosaic]] must be are compatible with one anothereach other at any moment of time. ThusIt follows, therefore that a theory can only become rejected when it is replaced by an incompatible theory or theories.[[CiteRef::Barseghyan (2015)|ppp. 167-172]]{{PrintDiagramFile[[CiteRef::Fraser and Sarwar (2018)|diagram file=theorypp. 72-rejection-theorem.jpg}}74]]
It is important to note that the rejection of the axioms of a theory does not necessarily lead to the rejection of its theorems. The theorems may retain their place in the scientific mosaic after the axioms from which they are derived get rejected. Each theorem is assessed on an "individual basis by its compatibility with the propositions of the newly accepted theory."[[CiteRef::{{PrintDiagramFile|diagram file=Theory Rejection Theorem deduction (Barseghyan (2015-Fraser-Sarwar-2018)|p. 168]] If it turns out that a theorem or theorems are compatible with the propositions of the newly accepted theory, they remain in the scientific mosaic. Conversely, if the theorems are incompatible with the propositions of the newly accepted theory, they become rejected as per the theory rejection theorem.png}}
The theory rejection Implicit in the theorem has another corollary. A is the idea that each theory can become rejected not only when replaced is assessed on an "individual basis by theories of its own discipline, but by theories compatibility with the propositions of other disciplines as wellthe newly accepted theory".[[CiteRef::Barseghyan (2015)|p. Normally, we think 168]] If it turns out that a physical theory becomes rejected when a new physical previously accepted theory that is incompatible compatible with the old one becomes newly acceptedtheory, it remain in the agent's mosaic.
