Testing Gravity's Quantum Nature with Spin ⚡ экспресс
Original: "Relativistic Gravity-Induced Entanglement via Frame Dragging"
Physicists have devised a way to capture gravity's quantum essence through the twisting of space by a rotating mass.

A rotating mass drags space like a spoon through syrup. Physicists figured out how to catch quantum gravity with this: a particle flying by along two paths gets entangled by the rotation. If they see it, it proves gravity is quantum. The door to understanding the cosmos swings open.
🎯 Earth's rotation also drags space: in 2011, the Gravity Probe B satellites confirmed that our planet twists spacetime around itself, shifting gyroscopes by 37 milliarcseconds per year.
🎬 Quantum gravity inspires sci-fi writers to imagine devices that manipulate spacetime—from warp drives to gravity suits.
