Earth will have 25-hour day in next 200 million years

TUM scientists utilize a "ring laser" for studying Earth’s day-length evolution.

The advanced device at Geodetic Observatory Wettzell captures rotational differences with precision.

 Despite design challenges affecting exactness, a corrective algorithm was developed.

This algorithm enables measurements with nine-decimal precision.

The precision equates to a fraction of a millisecond per day.

Detailed understanding of Earth’s rotational dynamics is achieved.

Fluctuations of approximately 6 milliseconds every two weeks are revealed.

These insights significantly contribute to improved climate models.

 Weather phenomenon comprehension is also enhanced.

Over geological epochs, Earth's day length has experienced significant variations.
