- A question if Black Hole entropy is a problem.

We know that there is no law of conservation for the entropy. It is quite the contrary: If we have a closed system without exchange of heat the entropy cannot get less. It will reach the max. If we have not a closed system but a stream of entropy only into a system, the entropy will increase.

From my understanding the information stored with raising entropy is getting less.

In Thermodynamics we are free to draw a virtual sphere around a black hole, the system boundary.

My question is a very basic one: Why is it a problem that a black hole gets incredible amounts of entropy and creates more and more until it is not "feeded" anymore, tearing apart the things falling into it? Who cares if information is destroyed which is always the case if entropy dominates - and because physisicst seem to care about the information, why?

Just a little example: If I fly a rocket into the sun the information stored in the rocket, whatever it is, is gone, lost in entropy. When I fly a rocket in a black hole and it is completely torn apart approaching the singularity, if not long before - suddenly we care about the information!? It is gone! Period... Okay, you got my point.

I just don't see the problem, if I am an external observer...

Thanks for your help to understand the problem better.

PS: Okaaayyy, one thing I didn't take into account at all: How could I measure how much entropy a black hole has because I only get it via a comparison, interesting... uuuh, this may be interesting, thanks again.
