| Popis: | In "Emergent Gravity and the Dark Universe," Verlinde mistakenly used a wrong relation $\Phi_B(r)=GM_B(r)/r$ to derive one of his equations. Of course, a correct relation is $\Phi_B(r)=\int GM_B(r')/r'^2 dr'$. This makes the equation that he derived not valid. If this equation is nevertheless correct, his earlier equation from which he derived it is wrong. Comment: Misunderstanding. $\Phi_B$ is not a Newtonian potential (i.e., related to time time component of metric) but a potential related to space space component of metric |
