Ziua a avut 19 ore. Controversa ce încaieră cercetătorii. Când s-a întâmplat fenomenul, ce rol a avut Luna? • Newsweek România

The theory that Earth's days lasted 19 hours for nearly a billion years has sparked debate among scientists. Proponents argue this was due to a unique interaction between the Moon and Earth's atmosphere, which temporarily halted the planet's rotational slowdown. Studies from 2023 suggested a significant stagnation period during the Proterozoic era, while a 2024 analysis questioned the geological evidence supporting this claim. Further research indicated that the length of a day around 1.787 billion years ago was closer to 17.7-17.9 hours. Despite ongoing investigations, the exact duration of Earth's days in the distant past remains uncertain.
