| Abstract: |
Until now, gravitational physics has never been tested in the
strong field limit and even the actual nature of astrophysical
black hole candidates is far from being clear. However, this
situation may change in the near future: very long baseline
interferometry technique at sub-mm wavelength will be hopefully
able to observe the direct image of SgrA* and thus study the
space-time around the super-massive black hole candidate at the
Galactic Center. In this talk, I discuss the possibility of testing
the Kerr bound |a*|≤1, which is the condition for the
existence of the event horizon in Kerr space-times. |
