PhysicsThis test could reveal whether gravity is subject to quantum weirdness If gravity is a truly quantum entity, something as simple as measuring the strength of an object’s gravitational field should change its quantum state ¿ìè¶ÌÊÓÆµ
PhysicsCause and effect may not actually be muddled in the quantum realm The direction of cause and effect was brought into question for quantum objects more than a decade ago, but new calculations may offer a way to restore it ¿ìè¶ÌÊÓÆµ
