Hi(adsbygoogle = window.adsbygoogle || []).push({});

I have a simple question

in GR we can claculate the gravitational acceleration of the black hole with the Equation :

[tex]

\[

a = \frac{{GM}}{{r^2 \sqrt {1 - \frac{{r_s }}{r}} }}

\]

[/tex]

now , the acceleration of a mass which falls into the black hole at the event horizon (when[tex]

\[

r = r_s

\]

[/tex])

goes to infinity . So the velocity of this mass must be greater than the speed of light.

How ???????????????????????
