A day on Earth would be 25 hours

As society progresses, The world itself is also undergoing notable changesSome of them are so long that they were revealed only thanks to the study of scientists. Researchers in Technical University of Munich (TUM))They have managed to update the tool An “ultra-precision” laser designed to measure the Earth’s rotation speed With unprecedented accuracy.

The new measurements indicate that, millisecond by millisecond, the planet will transition out of existence 24 to 25 hours a day for the next 200 million years. The length of the day is affected by its heterogeneous composition Gravitational interactions with the Moon and the SunIt has major implications for astronomy, meteorology, and climate forecasting models.

They detect cycles of six milliseconds every two weeks

The ring laser tool, which has been improved since its implementation in 2011, It has become a major tool for understanding Earth’s movements. Although it faces technical difficulties, such as asymmetry in the laser beams, the new correction algorithm has raised the accuracy to extraordinary levels, reaching reveal The Earth’s rotation fluctuations are only six milliseconds every two weeks.

Professor Ulrich Schreiber, leader of the project, highlights the importance of these measurements not only in astronomy, but also in astronomy. Create accurate climate models and understand weather phenomena.

Through these investigations Scientists can trace the historical evolution of the Earth’s rotation speedRevealing that days witnessed a gradual lengthening over millions of years, and that, Within 200 million years, We may live in a world where days are 25 hours long.
