All the individual masses and linear and angular momenta (and electric charge) are hidden behind the trapping surface. By examining that surface you can&amp;#x27;t tell how many bits and pieces there were inside when it formed initially or which fell in later; only the aggregate values are available. And all of those bits and pieces are crushed into a very small configuration (up to an outright singularity) compared to the volume of the interior. So the interior is…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1310.7564/"&gt;Paper and discussion history&lt;/a&gt;.
