The Quantum Fabric of Spacetime ⚡ экспресс
General relativity is a background-independent theory of dynamic classical spacetime geometry. Quantum theory is formulated in classical spacetime as an inherently probabilistic, contextual theory of nonclassical interfering probabilities, with a fixed Born rule. It is suggested that the quantum nature of spacetime, including a noncommutative dual partner of classical spacetime, is the reason for the probabilistic and contextual character of quantum theory with a fixed Born rule. In quantum gravity, quantum theory is 'gravitized' into a background-independent framework with dynamic and contextual quantum probabilities. This entails intrinsic triple and higher-order interference for massive quantum probes, shedding light on string theory, the observed vacuum energy, and elementary particle masses.
According to Einstein, spacetime is a flexible fabric, curved by matter. But in the quantum world, everything is different: particles are smeared over a probability cloud, governed by a rigid rule discovered by Max Born. New research unifies these pictures: spacetime itself turns out not to be smooth, but a vibrating fabric.
On the micro level, this fabric constantly trembles, like fine silk in the wind. Its oscillations are not just noise; they generate quantum probabilities. The stronger the tremble, the fuzzier a particle's fate becomes.
Spacetime not only dictates probabilities but also endows particles with mass. The trembling void resists motion, turning clumps of energy into weighty particles. This same idea sheds light on dark energy and the masses of elementary particles. Thus, the quantum trembling of the cosmos ties gravity and the micro-world together.
🎯 Perhaps the trembling of spacetime is the very reason elementary particles have mass.
