&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Changwei Hu&amp;#039;&amp;#039;&amp;#039; (Hu Changwei) is a Chinese independent researcher known for an ether-based approach to gravitation and relativity. He is listed in &amp;#039;&amp;#039;[[The Worldwide List of Dissident Scientists]]&amp;#039;&amp;#039;.&lt;br /&gt;
&lt;br /&gt;
==Work==&lt;br /&gt;
Hu argues that space is filled with a physical ether and that light is a wave in this ether, propagating at a speed that varies with the ether&amp;#039;s density. On this basis he has attempted to derive the Lorentz transformation from fluid mechanics and to reinterpret the foundations of relativity theory, cosmology and gravitation as consequences of a compressible ether. He has published on &amp;quot;the theory of compressibility ether&amp;quot; and has contributed a chapter applying the &amp;quot;Smarandache geometrical model&amp;quot; to macro-physics, in which he distinguishes Newtonian, special-relativistic and general-relativistic subspaces of a single geometry. He is associated with the Beijing Relativity Theory Research Federation.&lt;br /&gt;
&lt;br /&gt;
Hu&amp;#039;s ether-based reformulations lie outside the scientific mainstream and have not been adopted by the physics community.&lt;br /&gt;
