A  scientific theory  is an explanation of an aspect of the  natural  world that can be  repeatedly tested  and verified in accordance with the  scientific method , using accepted  protocols  of  observation , measurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an  experiment . [1] [2]  In circumstances not amenable to experimental testing, theories are evaluated through principles of  abductive reasoning . Established scientific theories have withstood rigorous scrutiny and embody scientific  knowledge . [3]
