In a discussion of what holds airplanes aloft, a classmate offers this hypothesis: "airplanes are held up by an undetectable force field produced by invisible magnets." which word in this statement is most likely to keep the statement from satisfying the criteria for a scientific hypothesis? why? b. during class, a fellow student explains the result of an experiment that solves the homework problem assigned. when asked how they solved the problem, they said the answer came to them in a dream. you wish to find the answer in the same fashion, but even though this answer ends up being correct, why would this not be a scientific experiment?
