I&#x27;m sure I was not clear, since that was the first pass.<p>What the experiment indicates is that the Earth varies in size. Roughly:<p><pre><code>  measured distance of 10^-20 meters 
  4km is 10^-5 of earth circumference.
  delta Earth&#x27;s circumference 10^-25
  total distance change in earth&#x27;s diameter = 10^-18 meters
</code></pre>
Given the non-intuitive nature of geology[1], I am saying that the possibility that the Earth varies that much in dimension due to it&#x27;s internal structure is not so vanishingly remote as to be left unaddressed. Saying it&#x27;s ten or a thousand times less likely doesn&#x27;t move the needle much at that scale...if such a thing were said.<p>[1]: I&#x27;m old enough to have been introduced to platetechonics as a <i>distuptive</i> theory.
