(6, 5) in terms of the metric distance r(t) = S(t) · χ get the exact Newtonian form: ... &amp;quot;where M g (r) = ... is the gravitating mass of a ball with radius r(t). So according to general relativity the dynamics of the whole universe is determined by the exact Newtonian acceleration and Newtonian kinetic plus potential energy conservation (here velocity of light c does not change the Newtonian character of the equations).&amp;quot; Page 7, I believe.…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1501.01919/"&gt;Paper and discussion history&lt;/a&gt;.
