Story summary

Researchers from TUM and the University of Bonn used a high-precision ring laser in Wettzell, Bavaria, to measure Earth's axis fluctuations.
Their 250-day experiment achieved accuracy 100 times greater than previous methods, improving our understanding of Earth's movements.
Earth's axis wobbles due to its shape and gravitational forces from the sun and moon.
The ring laser operates independently, delivering immediate results with a resolution of under an hour.
Future enhancements may measure spacetime distortion from Earth's rotation, testing relativity theories.
