A scientific theory is a well-substantiated explanation of some aspects of the natural world, based on a body of knowledge that has been repeatedly confirmed through observation and experiment. Scientist creates scientific theories from hypothesis that have been corroborated through the scientific method, then gather evidence to test their accuracy. The strength of a scientific theory is related to the diversity of phenomena it can explain, which is measured by its ability to make falsifiable predictions with respect to the phenomena. Scientific theories are the most reliable, rigorous, and comprehensive for of scientific knowledge. The scientific method involves the proposal and testing of hypotheses, by deriving predictions from the hypothesis about the result of future experiments, then performing the experiments to see whether the predictions are valid. Theories do not have to be perfectly accurate to be scientifically useful. Scientific theories aren’t the end results of the scientific method; they can be proven or rejected like a hypothesis. A scientific theory is the base for furthering scientific knowledge and putting it to use. Scientific theory is the most reliable, comprehensive form of scientific knowledge. Laws and scientific theories are produced from the scientific method through the formation and testing of hypotheses, and may predict the behavior of the natural world.
In non-science context, the word “theory” points toward something that is unproven or speculative. In science, on the other hand, a theory is an explanation or model based on observation, experimentation, and reasoning. Any scientific theory has to be based on a careful and rational examination of the facts. Theories must include statements that have factual consequences. Both scientific laws and scientific theories are made from the scientific method through the formation of testing of hypotheses, and can predict the behavior of the natural world. Both are...
