The Earth will have 25-hour days: when will it happen and the reason for this historical adjustment / FP
Have you ever felt like there aren’t enough hours in the day to do everything you want? Good news: A study from the Technical University of Munich (UTM) suggests we could have 25-hour days in the future.

This forecast is based on the analysis of the gradual slowdown in the planet’s rotation, that is, the movement of the Earth every 24 hours, responsible for days and nights, a phenomenon that has been the subject of study for years.
According to scientists, the Earth has experienced a slowdown in its rotation throughout its history, a process driven by various factors such as the gravitational influence of the Moon, the friction of ocean tides and atmospheric circulation.
These changes, although imperceptible to us on a daily basis, have left their mark on the geological history of the planet. 1.4 billion years ago, an Earth day barely lasted 18 hours and 41 minutes, while in the age of the dinosaurs it lasted to 23 hours.
The UTM study, which has managed to measure the Earth’s rotation speed with unprecedented precision, was based on data collected using an optical ring laser interferometer, an advanced tool that allows detecting variations in the Earth’s rotation speed with a resolution of a few milliseconds.
The results indicate that the Earth’s rotation speed is gradually decreasing at a rate of approximately 1.7 milliseconds per century. This phenomenon, mainly attributed to factors such as tidal friction and seismic activity, could lead to Earth days being extended to 25 hours.
