<p>Create biographical page for person listed in The Worldwide List of Dissident Scientists (web-verified; red-link batch 7)</p> <p><b>New page</b></p><div>{{Infobox scientist<br /> | name = Claude R. Cahen<br /> | fields = Physics<br /> | known_for = Proportional-expansion theory of gravitation<br /> }}<br /> <br /> &#039;&#039;&#039;Claude R. Cahen&#039;&#039;&#039; is an author known for proposing that gravitation is an apparent effect produced by the continual proportional expansion of all celestial bodies. He is listed in &#039;&#039;[[The Worldwide List of Dissident Scientists]]&#039;&#039;.<br /> <br /> ==Ideas==<br /> In the paper &quot;The Proportional Expansion of Each and Every Celestial Body as the Cause of Gravitation&quot; (&#039;&#039;Physics Essays&#039;&#039;, Volume 6, pages 473–486, 1993), Cahen argued that gravity is not an active attractive force but an &quot;apparent, fictitious force&quot; generated by the geometric radial expansion of every heavenly body in the universe. He introduced a &quot;universal constant of expansion&quot; and suggested that the differing densities of the Earth&#039;s mantle and crust produce a slightly heterogeneous expansion of the planet. He returned to the subject in a later &#039;&#039;Physics Essays&#039;&#039; article in 2023. These ideas belong to the &quot;expanding Earth&quot; tradition and lie outside mainstream physics, which explains gravitation through general relativity and does not accept an expanding Earth.<br /> <br /> ==External links==<br /> * [http://physicsessays.org/browse-journal-2/product/661-1-claude-r-cahen-the-proportional-expansion-of-each-and-every-celestial-body-as-the-cause-of-gravitation.html &quot;The Proportional Expansion of Each and Every Celestial Body as the Cause of Gravitation&quot; (Physics Essays)]<br /> * [https://independent.academia.edu/CCahen Claude Cahen on Academia.edu]<br /> <br /> [[Category:Scientist|Cahen Claude]]<br /> [[Category:Worldwide List of Dissident Scientists]]</div>
