The fuzziness, researchers theorize, blurs the envisioned highway to unification. The blurring, they say, is brought about in the interplay of nature's forces, where, in certain models of unification, ...

A rewrite of quantum mechanics that includes the force of gravity could finally achieve one of physicists’ biggest goals and reveal the ultimate fuzziness of time ...

The idea that space-time might be fundamentally fuzzy is much debated among theorists. A search for signatures of this effect on light from distant cosmic sources has come up empty-handed, but shows ...

The fuzziness of the quantum world has been demonstrated on its largest-ever scale, probing the limits of quantum mechanics. More than a billion atoms inside a glass bead acted as a single quantum ...
