The Quantum Fabric of Spacetime ✎ express
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.
