New Equation Promises Breakthroughs in Quantum Gravity Research

3/9/2026

Summary

Story summary

Physicists at TU Wien led by Benjamin Koch propose a method to quantify spacetime with a new equation, the q-desic equation.
The q-desic equation implies particles may not always follow shortest paths predicted by classical physics.
Deviations at small scales are negligible, but cosmic-scale differences may emerge when considering the cosmological constant.
The work could enable a measurable test for quantum gravity and help address unresolved cosmic phenomena.
