Gravity is unlikely to be the cause of quantum collapse, suggests an underground experiment at Italy\u2019s Gran Sasso National Laboratory.\u00a0\u00a0TOMMASO GUICCIARDINI\/SCIENCE SOURCE<\/em><\/figcaption><\/figure>\n\n\n\n

It\u2019s one of the oddest tenets of quantum theory: a particle can be in two places at once\u2014yet we only ever see it here or<\/em> there. Textbooks state that the act of observing the particle \u201ccollapses\u201d it, such that it appears at random in only one of its two locations. But physicists quarrel over why that would happen, if indeed it does. Now, one of the most plausible mechanisms for quantum collapse\u2014gravity\u2014has suffered a setback.<\/p>\n\n\n\n

The gravity hypothesis traces its origins to Hungarian physicists K\u00e1rolyh\u00e1zy Frigyes in the 1960s and Lajos Di\u00f3si in the 1980s. The basic idea is that the gravitational field of any object stands outside quantum theory. It resists being placed into awkward combinations, or \u201csuperpositions,\u201d of different states. So if a particle is made to be both here and<\/em> there, its gravitational field tries to do the same\u2014but the field cannot endure the tension for long; it collapses and takes the particle with it.<\/p>\n\n\n\n

Renowned University of Oxford mathematician Roger Penrose championed the hypothesis in the late 1980s because, he says, it removes the anthropocentric notion that the measurement itself somehow causes the collapse. \u201cIt takes place in the physics, and it\u2019s not because somebody comes and looks at it.\u201d<\/p>\n\n\n\n
