Natural Order and Science

Alex, I have a few questions about blackholes and physics that I have been pondering and would be grateful if someone who actually knows about this stuff could help explain to a lay person like me.

If a blackhole does not contain an entry to another universe and isn't a wormhole, but is a closed system, then what happens to all the light that falls inside? Is there a limit to how many photons can fit into a finite part of spacetime?

If you combine two neutron stars then you can form a blackhole because the gravity increases to the point whereby light cannot escape. How do we know that the singularity isn't actually just a really big neutron star? Or even formed from something even denser than a neutron star, say like a quark star?

Continuing on from this, I understand with normal stars that there is gravitational pressure pulling stuff together and outward pressure maintaining a certain size. Nothing can go faster than the speed of light, but can there be enough outward pressure equal to the gravitational pull strong enough to stop light escaping?

Why is it that information can not be destroyed in quantum mechanics? Is this because information = energy?

How much wood would a woodchuck chuck if the woodchuck chucked wood at near light speed?

Thanks.
