&gt; And this is the sense in which physicist talk about information, the description of the state space. If you throw something into a black hole the only things that remain visible are things like the mass, the charge or the (angular) momentum but you just lost all the details about the thing you threw into the black hole which is a problem for our understanding of physics.<p>Why is that a problem? The information could still exist, it&#x27;d just be inaccessible...<p>This seems no different to me than a spaceship going beyond the Hubble horizon.
