A new analysis shows: for particles to become entangled, gravity alone isn't enough—the quantum nature of space itself is needed.

Two people on a pendulum swing feel the sway but don't read each other's minds. So it is with gravity: shared spacetime can link movements, but won't create quantum entanglement. The mistake in the new study? They missed the quiet notes—and the particles remained on their own. For a true quantum network, you need a quantum postman.

🎯 Gravity is so weak that even if you concentrated the mass of an entire mountain into one point, its quantum influence would remain ghostly. That's why hunters of quantum gravity dream of accelerators the size of the Solar System.
