Researchers Make Most Accurate Measurements of Earth's Rotation

Researchers at the Technical University of Munich (TUM) have successfully made the most accurate measurements of the Earth's rotation so far. The measurements were made after more than two decades spent building the necessary instrument at the Geodetic Observatory Wettzell , located in the Bavarian forest in Germany . It is common knowledge that the Earth's rotational axis is not entirely symmetric due to the shape of our planet. However, even the speeds at which the Earth spins are not constant.

This is because out world isAs the Earth spins, the liquids inside the planet also rotate, and the mass shifts can result in acceleration at times and braking at others, resulting in varying speeds. Researchers built the ring laser equipment at Wettzell Observatory to measure the spins accurately and have spent the recent few years optimizing it.The ring laser equipment consists of four mirrors enclosed in a closed body called a resonato
