scientific theory

A scientific theory is a well-substantiated explanation of some aspect of the natural world that is traditionally acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation. As with most (if not all) forms of scientific knowledge, scientific theories are inductive in nature and aim for predictive power and explanatory capability.
