Gravity's Quantum Nature: Physicists Levitate Micro Diamonds in Search for Answers

An international team of physicists plans to levitate micro diamonds in a vacuum to determine if gravity is quantum in nature. By entangling microdiamonds made up of one billion atoms or more, the researchers aim to measure the effects of gravity on each entangled diamond and observe if these effects are transferred via superposition. If successful, the experiments could provide evidence for the quantum nature of gravity and potentially unify general relativity with quantum mechanics.
