  • Earth Heading Towards a 25-Hour Long Day as Rotation Slowing at 1.8 Milliseconds per Century
 

Scientists are saying that a slowing down of the planet’s rotation may cause longer days in the long-term future.

Many people even now feel that the evening hours seem to drag on forever. Scientists have reassured them that it is not their minds playing tricks on them.

Rather such is actually happening with the passage of time although very slowly yet imperceptibly. A study of the earth’s tides shows that tidal braking is occurring and so longer days may actually lie in humanity’s fate. 

However, there is no reason to start going gaga just yet. The difference is very small for now. In fact, it is merely 1.8 thousandths of a second per hundred years or so, according to DailyMail.

Two million centuries will have elapsed before a single hour’s time span accumulates in our normal 24 hour long day. The tides are affected by the lunar gravity. This has a braking effect.

Thus water drags along and heaps up on the earth’s surface. The earth’s spinning about its axis undergoes a slight lag in time. While the earth’s rotation slows down, the moon’s orbit grows by a certain distance. 

A record of past eclipses was taken into account for studying this phenomenon. The eclipse falls on a certain portion of the earth. The oldest records came from the times of the Babylonians and Ptolemy not to mention Ancient China, the Dark Ages and the Arab Conquests.

One thing that could be said with accuracy was that the days were definitely getting longer as time elapsed. The rate of rotation had took off at a tangent from the norm. Although most of this change is very small, yet in a matter of millions of years, all this could add up to a substantial amount of time span. The day could go from a 24 hour period to a 25 hour schedule which is a big difference in geological evolutionary terms.
