Why a day can last 25 hours in the future

When will people have an extra hour to sleep or work?

From 4.5 billion years ago, our earth was made up of clouds of gas and dust. Meanwhile, an object the size of Mars that collided with the Earth caused a cataclysm that caused the time of day from 6 hours to increase to 24 hours as it is today.

Experts at Durham University and the British Maritime Calendar Monitoring Agency compared historical records with a planetary model capable of calculating the time and location of people who could observe things. Astronomical lawsuit in the case of a rotating axis does not change during 2735 years to learn about the change of Earth's rotation.

After collecting data in the history of the occurrence of eclipses, eclipses and other astronomical phenomena from 720 BC to 2015, the experts have found the cause of increasing each day's length. The main thing is the " tide brake " phenomenon.

" Tide brake " is a phenomenon created by gravity from the Moon. Each year, as the Earth's axis slows down, the moon's orbit increases by 4cm and causes this phenomenon.

However, " tidal braking" is not the only cause of increased day time. Beginning at the end of the most recent ice age, the land buried under ice has "risen" and returned to its position has also contributed to hindering the slow motion of the Earth.

In addition, changes in sea level or electromagnetic forces are also one of the factors that affect the change of the Earth cycle of 1500 per year.

Accordingly, every 100 years, the time in a day will only add 2 milliseconds, and it takes 6.7 million years for a day to add one minute. So for Earth to have 25 hours a day, we need to wait another 200 million years. Certainly until then, there are many changes that happen and what it is, only their later ninth generation will know.
