There&#x27;s no &quot;easy science&quot;<p>Also, knowing what&#x27;s testable requires testing itself. Science has always been about incremental fraying at the edges of knowledge to answer 1 little question and open up 100 more. Things might not be perfectly testable today but that doesn&#x27;t mean they won&#x27;t be in the future or that we can&#x27;t someone make progress with theory and models.
