We looked at how science explores the universe, the scientific method. All scientists make observations of some aspect of the natural universe. From those observations, they propose ideas that relate their observations to already-known phenomena. These hypotheses are tested by means of experiments that either support or disprove the hypothesis. A principle that explains a set of related hypotheses is called a theory or law. Theories have predictive value, and must be continuously tested. The new tests either support the theory or cause it to be discarded or refined (e. g. newton"s laws of motion hold well for motion much slower than the speed of light). Pasteur disproved the hypothesis of spontaneous generation for microbes, via ingenious experiments with flasks with narrow convoluted ends.
