The Earth’s rotation is accelerating. And if it continues like this, our planet will sway in a few million years…well, even faster.
Well, we charge a little, but the simple fact that time on Earth has not been the same since, say, a year ago, is also a fact. The Earth is spinning faster and faster and has been for some time.
We have some hard data: the sun rises from the east, we know when the seasons begin and the day lasts 24 hours. But the latter is not entirely true, because the Earth has been spinning faster and faster on its axis since 2020. In this way there are always more beautiful facts about that Earth: so you can find out where you end up If you dig a hole in the other side of the world…
Return to the speed of the Earth’s rotation. The amazing thing is that scientists have no idea why this is so. They precisely track rotation and therefore time using atomic clocks. On July 29 this year we have shortest day Have you ever had.
Thus, faster rotation of our planet leads to shorter days. Don’t count on it being an hour so you can get home early; It’s (at the moment) about a millisecond.
The day lasted about 86,400 seconds, and 2020 was 28 days, the shortest since scientists began taking accurate measurements in 1960. They were all shorter than 86,399.999 seconds and the shortest, July 19, was 1.47 milliseconds – one thousandth of a millisecond The second – shorter.
On the 29th of July? That day lasted “only” 8,6399.99841 seconds and was therefore 1.59 milliseconds shorter.
Why is the Earth spinning faster?
A number of hypotheses have been put forward that it may be due to the core of the Earth itself, a possible influence from the oceans or even the climate. There are of course other theories.
“After the Ice Age, ice shelves began to move toward the North and South poles,” say researchers Matt King and Christopher Watson. Conversation. “Think of it as a ballerina bringing his arms inward and thus spinning faster. So the weight of the Earth goes to the center and as a result the Earth is spinning at a rate of 0.6 milliseconds faster per 100 years.”
Another interesting point is the influence of the moon. As we all know, the gravity of our satellite has a huge impact (among other things) on our oceans, causing tides. But the moon is moving away from us about four centimeters every year. And that could certainly affect the Earth’s rotation.
The Chandler effect has also been mentioned. It’s a shift in the Earth’s axis relative to our solar system, causing it to swing back and forth slightly.
What are the consequences?
Will the whole earth die in the end? About five billion are known for certain, because the sun rises and then the earth devour.
But in the happy news, the acceleration of the Earth will not take such a speed in terms of a doomsday scenario. Its effects are currently considered harmless.
Does it affect us all? The Apple Watch may be constantly running with “real” time, but more importantly; Airlines, aircraft carriers, and other time and GPS services should take these small differences into account.
