Noun
1. a well-substantiated explanation of some aspect of the natural world; an organized system of accepted knowledge that applies in a variety of circumstances to explain a specific set of phenomena; "theories can incorporate facts and laws and tested hypotheses"; "true in fact and theory"

(hyponym) reductionism
(part-meronym) law, law of nature
2. a tentative theory about the natural world; a concept that is not yet verified but that if true would explain certain facts or phenomena; "a scientific hypothesis that survives experimental testing becomes a scientific theory"; "he proposed a fresh theory of alkalis that later was accepted in chemical practices"
(synonym) hypothesis, possibility
(hypernym) concept, conception, construct
(hyponym) model, theoretical account, framework
(derivation) speculate, theorize, theorise, conjecture, hypothesize, hypothesise, hypothecate, suppose
3. a belief that can guide behavior; "the architect has a theory that more is less"; "they killed him on the theory that dead men tell no tales"

theory (theories)
Compare with hypothesis .Theories are well-established explanations for experimental data. To become established, the theory must experimentally tested by many different investigators. Theories usually can not be proven; a single contrary experiment can disprove a theory.

Theory
The word theory has a number of distinct meanings in different fields of knowledge, depending on their methodologies and the context of discussion.
In common usage, people often use the word theory to signify a conjecture, an opinion, or a speculation. In this usage, a theory is not necessarily based on facts; in other words, it is not required to be consistent with true descriptions of reality. True descriptions of reality are more reflectively understood as statements which would be true independently of what people think about them. In this usage, the word is synonymous with hypothesis. This common usage of theory leads to the common but misguided statement "It's not a fact, it's only a theory."
