You should read some Karl Popper (<i>Science as Falsification</i>).<p>You&#x27;re essentially getting at why science is both inductive and deductive.  Sure this article is inductive, but it&#x27;s conclusion is falsifiable, so  people can test the hypothesis over and over again.<p>Pointing out that they haven&#x27;t tested the everything in the universe, including the celestial teapot, doesn&#x27;t mean that it&#x27;s false.  It&#x27;s just that it has never been falsified yet.
