On a quantum chip, they recreated a tiny but wildly chaotic system of particles. Its entanglement was so strong that it turned into a hologram of a wormhole — a tunnel through space. The signal sent through it arrived differently depending on the sign. Such a trick opens the door to lab tests of quantum gravity.
🎯 The idea that gravity can emerge from entanglement is called the holographic principle — as if our three-dimensional world is projected from a flat surface.
🎬 In Interstellar, the wormhole was meant for people, and here — for signals, but the principle is the same.
