Quantum entanglement is a special connection between particles: they affect each other instantly, even across light-years. For a long time, it was believed that strong acceleration destroys this bond.

Fragile as ice in a furnace, quantum entanglement usually perishes from the slightest heat. Near a black hole, where space is twisted by Einstein's gravity and Hawking radiation Hawking's heats things up, any bond should be destroyed.

Quantum entanglement, when particles are linked so that the state of one instantly determines the state of another, is usually a fragile thing. Any disturbance, like heat, tears the connection apart. But what if the observer's own time is limited?
