The randomness of the quantum world is born from the constant trembling of spacetime itself.
Abstract

Typically, quantum theory describes particles using fixed spacetime as a stage. But the authors suggest that spacetime itself has a quantum 'underside' that gives rise to the probabilistic nature of quantum phenomena. This could explain why elementary particles have mass and shed light on the mystery of dark energy. Imagine: the stage starts dancing along with the actors—could this be the secret to the universe's makeup?

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.

Born's rule ceases to be ironclad: it depends on exactly how we 'stretch' the fabric in our experiments.

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.
