No. In science, facts are those phenomena which can be consistently observed and measured. A hypothesis is a testable, educated guess about what sort of rules might govern the behavior of the observed phenomena. Once a hypothesis is formed, it is then tested to determine how well it fits teh phenomena, and whether it can therefore provide a useful means of predicting the behavior of similar phenomena. If the hypothesis fails to provide an explanation with verifiable predictive power, it is rejected, and a new hypothesis is formed, then that new hypothesis is tested. If the hypothesis is verified -- testing shows that it does provide a useful explanation of teh phenomena with some predictive power -- then it may eventually become a _theory_, providing it stands up to repeated testing, and is not falsified (and therefore rejected). A theory represents a well-tested explanation for how a particular phenomenon or particular phenomena behave. All of the "testing" refered to above will be carried out according to the _scientific method_. So a "theory" is not a fact, but an -explanation- for observed facts. And a "Hypothesis" is a working model for a theory, a model awaiting testing, or in the process of being tested.
No, a law in science is a statement that describes a consistent pattern observed in nature, often expressed in the form of a mathematical equation. Laws do not explain why phenomena occur, but they describe what happens. Theories, on the other hand, provide explanations for why and how phenomena occur based on evidence and testing.
The reporter could not provide a good explanation for hiding in the mayor's garage. The official explanation for the plane crash was later amended to absolve the pilots of blame.
