SoCalSunset said:In that case, Mogurnda's deffinition of a theory, was actually correct. Then again, I'm not sure if you were trying to correct him, or just go into more detail.
Wasent trying to correct anyone, just give a definition.
Heres another, from wikipedia
" A theory is an established paradigm that explains all or much of the data we have and offers valid predictions that can be tested. In science, a theory can never be proven true, because we can never assume we know all there is to know. Instead, theories remain standing until they are disproven, at which point they are thrown out altogether or modified to fit the additional data.
Theories start out with empirical observations such as “sometimes water turns into ice.” At some point, there is a need or curiosity to find out why this is, which leads to a theoretical/scientific phase. In scientific theories, this then leads to research, in combination with auxiliary and other hypotheses (see scientific method), which may then eventually lead to a theory. Some scientific theories (such as the theory of gravity) are so widely accepted that they are often seen as laws. This, however, rests on a mistaken assumption of what theories and laws are. Theories and laws are not rungs in a ladder of truth, but different sets of data. A law is a general statement based on observations."
Or another, from - http://www.evolution.mbdojo.com/theory.html
"A scientific law is a description of an observed phenomenon. Kepler's Laws of Planetary Motion are a good example. Those laws describe the motions of planets. But they do not explain why they are that way. If all scientists ever did was to formulate scientific laws, then the universe would be very well-described, but still unexplained and very mysterious.
A theory is a scientific explanation of an observed phenomenon. Unlike laws, theories actually explain why things are the way they are."
