The earth's rotation slows down

Previously my friends know what the earth's rotation, the earth rotates on its axis so as to create a day and night. But what the earth's rotation is stable?, Not too ,, as we know the earth is rotating about 23 hours 56 minutes 4 seconds. an expert in astronomy from space agencies and national flights (LAPAN) states the time it takes the earth is rotating at a lot longer than the early days of the formation of the earth. Around 620 million years ago one day on Earth takes 22 hours. It is in the know of the geological data and the existing astronomical.

According to experts from LAPAN thomas, changes in the Earth's rotational speed to long time effect in one day on earth caused by external factors of the earth. There are some opinions that causes the earth's rotation slows down due to the heavy earth. There is also heavier because the earth rocks outer space / meteorid but it does not affect much, but there is the cause of possible tidal effects in the impact on the force of gravity to the moon with the result that the farther moon with the earth. Hundreds of millions of years ago, the moon is also experiencing a slowdown as the earth's rotation right now. The position of the moon was very close to the earth because the moon is actually derived from the earth material ejected after the collision with celestial bodies of mars. Because the condensation process in a round end like this. Rotation also increasingly slow month, an estimated hundreds of millions of years the moon will rotate during the 48 days when the Earth.

If the condition continues and is associated with the earth-moon system, the sun, the synchronization of the earth and the moon will be more intense than now, that organ, while rotation of the moon this time and the time of the revolution in the earth (1 month) was almost the same. Rotation of the moon takes 27.3 days, while the revolution in the earth about 29 days, 12 hours, 44 minutes, 2.8 seconds.

In a time when hundreds of millions of years to slow the rotation of the moon and the earth's rotation slows down, the astronomers predicted that there is only one area of the earth that will see the moon. The position of the moon would be further away from earth. Do not worry, it will happen around 6000 years back (our great-grandson gets maybe yes, hehehe).

At that time, a result of rotation of the earth and the moon are increasingly slowed, the season in the southern hemisphere and northern hemisphere will be exchanged. So if the earth is now in july northern part of the summer experience, in July 6000 another year will experience a strange winter ... yes, worthy only of the weather now is not sure, oh yes the earth's rotation early in the Earth's formation approximately 6 hours, crazy 1 day = 6 hours, 4.6 billion years ago 1 day = 14 hours, 620 million years ago 1 day = 22 hours, now 1 day = 23 hours, 56 minutes, 4 seconds ... The rotation of the earth experienced a slowing of about 0.005 seconds per in the calculation based on atomic clocks .... (From various sources)
