What kills Schrödinger’s cat? Gravity may not be the answer
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

Scientists opened a sealed envelope after 10 years. Gravity still didn’t make sense
A decade-long NIST experiment has produced a new measurement of the universal gravitational constant that differs unexpectedly from another leading result, deepening a 225-year-old physics puzzle. The discrepancy is tiny, but for one of nature’s most fundamental constants, it is
