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.

If you accelerate one of four entangled particles to enormous speed, their quantum entanglement doesn't just melt away: it first weakens, then strengthens again. Physicists discovered this unexpected twist while studying the behavior of a special state called the Dicke state in a world governed by the laws of relativity.
