Chapter 4. A good scientific hypothesis is the opposite of this. If there is no experimental test to disprove the hypothesis, then it lies outside the realm of science. Scientists all too often generate hypotheses that cannot be tested by experiments whose results have the potential to show that the idea is false. Science advances by conducting the experiments that could potentially disprove our hypotheses.
Increase the efficiency and impact of your science by testing clear hypotheses with well-designed experiments. View full bio. And the more controversial a theory is, the more experimental verification is required. Wide acceptance comes from repeated, different experiments by different research groups. As an example, in , Albert Einstein published two papers on what we now call the Special Theory of Relativity.
In these papers, he made a series of arguments that dramatically altered our notions of how the universe works. He argued that different observers measure the passage of time differently; they also measure different lengths for moving objects. He also showed that matter and energy are different forms of the same thing and theoretically can be converted into each other. His theory made detailed, quantitative and falsifiable predictions that could be tested experimentally.
Einstein was prepared to drop the entire theory if even one experiment convincingly contradicted his predictions. It took a long time for many of these predictions to be tested. And relativistic theory has also been used as the basis for several technological advances, including GPS satellites , nuclear power and unfortunately nuclear bombs.
There is absolutely no doubt among anyone in the physics community about the validity of the Theory of Relativity. For an example of an unsuccessful theory, consider the announcement in March of a mechanism for nuclear fusion in a table-top configuration.
