As with most words, there can be more than one definition for the word, depending on how the word is used. So, the word 'theory' can have different meanings whether it is used as a science word or in every day speech.
The common use of "theory" is a "hypothesis" or a guess.The scientific usage implies accuracy and precision (strict testing and retesting that produce the exact same results). Consequently, the results of those tests are considered to be "facts." The only reason why they're not precisely called "facts" is because science allows the possibility that researches overlooked something in determining that theory.
People assume that because they are the same word, that they mean the same thing in both contexts - which is not an unfair assumption to someone who is outside the scientific community.
The scientific use of the word "theory," is an hypothesis which has not been proved yet. Once it gets proved, then it becomes a scientific law. If the theory cannot be proved or debunked, then it remains a theory; such as the theory of evolution. The common use of the word theory is more as an explanation, such as "what is your theory on why the sky is blue?" Response: "well i think it's because blue shines through more than the other colors." So it's kind of a mix of the scientific theory and explanation.Well, sort of . . .A scientific theory is an explanation of behavior that most closely fits observations as well as being testable and repeatable. It may not be provable a priori (e.g. mathematically) but can still be verified observationally.An example is the Theory of Gravity, which describes the behavior of objects in a gravitational field. if For example if someone walks off the edge of a cliff they will always fall downwards (unlike a certain Road Runner and Coyote); moreover, if the fall is measured the item will accelerate at approximately 9.8 m/sec/sec anywhere on the surface of the earth. Portions of gravitational behavior are provable, such as the fact that the strength of gravitational attraction between two items varies inversely with the square of the distance between them, so in some cases you also hear of the Law of Gravity as well as the Theory.As the previous poster noted, "theory" is interpreted as a hypothesis or guess in common usage. It's a bit like the use of the word "penny" to describe a 1-cent coin in the US and a few other countries. The coins are actually cents but everyone calls them pennies in colloquial conversation. However the confusion between the scientific meaning of the word theory and its colloquial meaning causes huge amounts of misunderstanding when discussing contentious issues such as evolution. It's common to hear non-scientists claim "it's only a theory", interpreting the word as "guess" when in fact it's being used in its strict scientific sense. As more than one person has said about the above-mentioned Theory of Gravity, "If it's 'only' a theory, please stand 3 feet from the edge of a cliff and walk 5 feet forward!"In science a theory has been rigorously tested against reality. In common use its just someone's guess (which is what a scientist would call a hypothesis).
In science the word 'truth' is used very sparingly to reflect the experimental nature of science. Scientists do not rush to brand something 'true' even if it can describe and predict a natural phenomenon excellently, such as the case of the atomic theory. Before more evidence is gathered and a better theory proposed, the currently theory is accepted as the relative 'truth' in the field and respected as such. Scientific theories of the day are paradigms of human understanding of the world. Being 'just a theory' does not preclude it from becoming the eventual truth when human knowledge of the universe is complete.

Quantum theory
Quantum theory is a science word. It begins with the letter Q.

in real science, anything with the word theory in-front of it means it hasn't been disproven - for example gravity is a theory.
It has more to do with Technology or Applied Science. 'Discovery' would be the more Pure Science-y word.

The definition of the word science analysis is " a method of investigation involving observation and theory to test scientific hypotheses."
Yes, planet is a science word. To be more specific its a noun.
No, the word "science" is a common noun. Proper nouns are capitalized.
In science, the word "theory" is USUALLY used for well-established theoretical frameworks, that are generally accepted as being true. This is the case with the theory on protoplanets - it is generally held to be true.
