Scientists at the Technical University of Munich (TUM) have discovered that a day on Earth could eventually extend to 25 hours. The research marks a significant advancement in understanding Earth's rotation through rotational dynamics. Contrary to common belief, Earth's rotation does not adhere to a precise 24-hour cycle. This inconsistency is attributed to the Earth's heterogeneous composition - a blend of various solids and liquids, each influencing the planet's rotational speed.
Interestingly, the Earth's day length has been gradually increasing over time. During the era of the dinosaurs, a day lasted only 23 hours, and 1.4 billion years ago, it was a mere 18 hours and 41 minutes. Projections suggest that in a mere 200 million years, a day will extend to 25 hours. This evolving dynamic of Earth's rotation underscores the importance of advanced measurements, though it leaves one to wonder who or what might be around to witness these changes in the distant future.
