New Scientist : The Casimir effect arises when metal plates held parallel and extremely close together in a vacuum attract each other. It happens because the metal sheets damp quantum fluctuations between the plates but not outside them. Because the effect is generic to quantum fields, it could have counterparts in other forces. In a new paper , James Quach of the University of Tokyo proposes that detecting a gravitational Casimir effect would constitute evidence of gravity’s quantum nature. Confining quantum fluctuations in a gravitational field could be done, says Quach, by using plates made from supercooled superconductors.
