To this question:
about the possibility of a sufficiently large black hole not containing a singularity John Rennie posted an answer containing information I had not seen before.
Here is John's quote: For the charged and rotating black holes things are more complicated, because there are timelike paths that take you through the event horizon, miss the singularity and back out again.
Quite clearly this refers to matter that crosses the Event Horizon to the interior and is expelled again because the time-like path avoids the singularity.
Now, in this question:
the only answer on the page is from Bob Bee who is quoted now: possible to extract energy, charge and mass from a BH, without extracting any actual particles. Two reasons, besides the obvious one that no particle escapes the horizon.
Bob's answer seems to conflict with John's but are the two actually in agreement?
They might be if matter can enter and leave the black hole but not in the same form. That's the only reasoning I can come up with by myself.
Please excuse me though if I have misunderstood something entirely. The point of asking this question was to clarify the point that matter takes an infinite amount of time to cross the horizon from the perspective of an outside observer. In John's answer matter crosses and spends time within. Would this matter also take an infinite amount of time to re-enter into causal connection from the perspective of an outside observer?
