The scientific use of the word "theory" is different to that used by the non-scientist. If it were mere speculation unsupported by facts, scientists would call it a "hypothesis" and generally try to disprove it. As a large body of evidence supporting a hypothesis is accumulated and all attempts to disprove the hypothesis fail, then it becomes accepted by science as theory. A theory, as the term is used by scientists, means an explanation that is strongly supported by evidence. The following article helps explain this further: === Theory vs. Hypothesis vs. Law by Katharine MJ Osborne The origin of this confusion has it's roots in the history of the development of science. When we speak of early, classical physics, we talk about laws, Newton's laws of motion for instance, the ideas have the weight of veracity. After all, the word "law" has a serious and strictly defined meaning in our culture. Back when Newton declared his laws, he believed them to be absolute descriptions of how the universe worked. At the time, they were irrefutable. We now know that his laws are in fact approximations, rules that work when describing motion on the macroscopic scale but which break at the quantum scale.
Since that time, science has gotten warier about describing anything as being absolute. Science, and physics in particular, is a tool to root out the true nature of reality. It can describe only what it observes which may or may not be true in every case. In order to say if something is absolutely true, every single possible case of a particular phenomena must be observed. In a universe as vast as ours, that's completely impractical. Science can say if something is probably true all the time if observations of a phenomena are the same in many cases. This tiny bit of waffling bothers many people who are not familiar with the inner workings of science. Shouldn't something be always true if it is true at all? Science just can't commit all the way to absolute - otherwise it wouldn't be science, it would be faith.
So science has tossed the use of "law" in favor of "theory". This "theory" does not mean "hypothesis" which is a speculation. In this case, think of music theory - definitely not a hypothesis, but a working set of rules that define a body of knowledge.
