Does the matter in a black hole get so compressed that it creates, theoretically, a distance smaller than the Planck length?

Hi Mathieu,

Probably not, because it will not be a black hole. Black holes that are larger than the Planck length behave as we study in space, responding nicely to relativistic formulae.

Smaller and it gets interesting. Those are so small they are essentially elementary particles They have a lifetime shorter than the Planck time. They do not follow relativistic rules at this point.
