Gravity is infinite at the singularity (the middle of the black hole). Everything gravitates towards that point. Our best understanding is that no information can exist here. Black holes "evaporate" over time -- by emitting Hawking radiation. This is probably where the information goes, in my layman understanding. |

No, the Hawking radiation and evaporation is exactly what causes the problem. If black holes were forever expanding, we could simply say "they have a structure inside that we can't detect, but that structure preserves the information; but, since it's past the event horizon, it will be, even in principle, forever beyond reach of our understanding and experiment".
However, if black holes eventually disappear, it means you have something like book => unknowable inside of the black hole event horizon => something observable outside. The problem now becomes that, from Hawking's discovery, the "something observable outside" is random thermal radiation, which can't contain information by definition. Hence, not just something unknowable, but a paradox (an inconsistency in the formal model).
