An international team of physicists plans to levitate micro diamonds in a vacuum to determine if gravity is quantum in nature.
Scientists have long theorized that gravity itself may be a quantum phenomenon, including general relativity Albert Einstein, but testing the idea in any practical way has remained elusive until now.
If successful, the experiments would not only affirm some of the theories proposing the quantum nature of gravity but could also finally unify general relativity with theories of quantum mechanics.
