Consider that Alice and Bob are two observers at rest separated by a long distance
Each of them has a measuring device that detects, respectively, two different quantum systems. The state of the joint system is said to be maximally entangled if, for many copies of the state, any measurement that Alice makes is completely determined by Bob's and vice versa. What would happen to their entanglement if Alice fell into a black hole and Bob stayed safely outside?

Interesting, if a little confusing to someone like me who has perhaps zero knowledge in this area.

The real tragedy I see here is that the two never in fact crossed paths, which appears the greater tragedy....
