| Aug 14, 2019 at 6:11 | comment | added | Wakabaloola | since you are talking about fundamental strings, first of all the string tension is not given by the inverse Planck length squared but rather by the inverse square of the fundamental string length, $\ell_s^2=\alpha’$, in particular $T=1/(2\pi \alpha’$. | |
