Physicists have put a decades-old idea about why the strange rules of quantum mechanics disappear in our everyday world to one of its toughest experimental tests yet. Deep beneath Italy’s Gran Sasso mountain, researchers searched for an extremely faint radiation signal predicted by a theory suggesting that tiny fluctuations in spacetime, caused by gravity, gradually destroy quantum superpositions. After 62 days of measurements with a highly shielded germanium detector, they found no such signal.
What kills Schrödinger’s cat? Gravity may not be the answer. Gravity may not be the answer A deep-underground experiment found no sign that gravity erases quantum weirdness in the way a famous decades-old theory predicted. Com At some point between the tiny world of particles and atoms and the much larger world we experience every day, quantum behavior appears to fade away.
Quantum mechanics allows particles to exist in combinations of possible states, a phenomenon known as superposition. That strange feature inspired Schrödinger’s famous thought experiment involving a cat that is both alive and dead until it is observed. Yet objects in the everyday world do not behave that way.
