First thorium nuclear clocks begin ticking in Vienna and Beijing

Built the first self-stabilizing nuclear clock

For 70 years, the world's most precise clocks have counted the vibrations of electrons orbiting an atom. In early October 2026, two teams — one in Vienna, one in Beijing — unveiled the first clocks that read time from the ticking of a thorium nucleus instead.

The century-long quest to reconcile quantum mechanics with gravity

New Capabilities

Published the q-desic equation framework

For a century, physics has rested on two incompatible frameworks: quantum mechanics (governing atoms and subatomic particles) and Einstein's general relativity (describing gravity as spacetime curvature). Every attempt to merge them produced mathematical infinities or unmeasurable predictions. Vienna University of Technology's "q-desic equation" (Physical Review D) may break this deadlock: quantum corrections to particle paths become observable at cosmological distances when the cosmological constant is included.
