Is it true that the Earth s rotation is speeding up in less than 24 hours a day?

*Yes**, it is true that the Earth's rotation is accelerating and the day is less than 24 hours.

Since 2020, the Earth's rotation rate has been accelerating, reaching the fastest speed in the last 50 years. This has resulted in some days where the length of the day will be shorter than 24 hours. For example, on July 19, 2020, the length of the day was reduced by milliseconds, while on June 29, 2022, the Earth accelerated again, with the shortest day ever recorded, with milliseconds less than usual.

In addition, on July 26, 2022, the day was also short, milliseconds shorter than 24 hours.

It is important to note that although the Earth's rotation rate is accelerating, the change in the duration of each day is so small that it is difficult for humans to notice. In addition, this change is influenced by the structure of the earth and the movement of the earth's crust, so it does not mean that the length of each day will continue to get shorter or longer.

It is true that the Earth's rotation is accelerating and that there are less than 24 hours a day, a fact that has recently been reported on some news programs and has attracted the attention of the scientific community.

There is no obvious tendency for the Earth to accelerate its rotation, on the contrary, the Earth's rotation is getting slower and slower. When life first appeared on Earth, a day was only about 8 hours a day. By now, 24 hours a day, the rotation speed has slowed down considerably.

I saw a new hot search on the Internet, that is, the rotation of the earth has been less than 24 hours. When I saw this hot search at that time, I actually had some small worries or some small surprises in my heart. What kind of concept is this?

I don't think many of my friends know about it. In order to find the answer, I think many people clicked into this topic, so the topic at that time was also relatively burning, and the curiosity of netizens was relatively high, so everyone participated in the topic to discuss, but everyone couldn't figure out what this topic meant for a long time. So let's take a look.

In fact, the results of this research are from other countries, researchers found that the rotation time of the earth is less than 24 hours, and I don't know when it suddenly becomes faster, although our alarm clock is still 24 hours a day, in fact, we live less than 24 hours a day. So many people have a question: why?

Obviously, our clock is still 24 hours a day. Yes, according to our alarm clock, our time has not been shortened, the day is still calculated according to 24 hours, but if the day is really calculated according to the rotation of the earth, then the day and night change relatively quickly, the time is shortened, and the day is really not enough for 24 hours.

In fact, it doesn't have any impact on us, because we still calculate it according to 24 hours, and there is a problem that the speed of the earth's rotation has accelerated, but the real speed will not shrink very short, so we don't have to worry too much, and it will not have any impact on everyone's life. Now the speed of the earth's rotation has accelerated, but it has not accelerated much, and if it is accelerated exponentially, then the impact on us will be greater. Studies have shown that if the Earth rotates 17 times faster, then objects near the equator will easily fly because of the problem of gravity and gravity.

And at that time, we should also recalculate the time, in fact, everyone should pay a little attention to these things, we live in the online world, so we can understand those news reports more quickly. We should focus on the news, not just the things in the entertainment industry. Because I think everyone has a curiosity and should explore the world, but we don't need to worry about it, it's better to live a normal life, if that day really comes, then we can't do anything about it.

This means that the global clock will have to be reset, but what's really interesting is that if there is less time, or an eight-hour workday, then we have less time to rest.

This means that the time we can have every day is shortening, and as people living on this earth, we should cherish and plan our time well, and not waste time on meaningless things.

It means that time flies faster, and 2021 passes faster than in previous years, and we must cherish time.

It means that there is not enough time, and many things need to be reallocated. The gravitational pull of the earth has become smaller, and humans have become lighter.

This means that time is getting less and less, and we should seize the time, not let it pass, and fight hard.

In fact, the Chinese are very wise and have different ways of keeping time.

Because the earth is affected by the greenhouse effect, the rotation speed is one second faster, and experts have a way to solve it, so don't worry.

This is mainly due to the acceleration of the Earth's rotation, which results in less than 24 hours in a day.

It's been 24 hours.

According to reports, scientists have found a shocking phenomenon, starting in 2020, the Earth's rotation speed has begun to accelerate for some reason, and the speed has reached the fastest speed in the past 50 years, this change means that although we have a 24-hour day, from a scientific point of view, in fact, there are no more 24-hour days. <>

We know that in addition to its revolution, the earth itself also rotates, and one revolution is equal to one year, and one rotation is equal to one day. According to the latest reports, in the past 50 years, the Earth's rotation time has been more than 24 hours. Of course, these lengths are generally calculated in seconds, and we can't feel them.

But since 2020, the Earth's rotation has taken exactly one second less than in 24 hours. At present, some scientists have proposed to remove the one-second gap to ensure that the clock and the time taken by the Earth to rotate remain the same. According to relevant data, on July 19, 2020, the time taken by the Earth's rotation on this day was less than 24 hours, and before that, the shortest day of the Earth's rotation occurred in 2005.

Will there be a day in the future when the earth's rotation speed will continue to increase and the time will gradually become shorter, and what impact will it have on us? <>

If the time taken for the Earth's rotation to change is really shorter, then the centrifugal force of the Earth will be correspondingly greater, and the Earth's gravitational force will become smaller. When the gravitational pull of the earth becomes smaller, everyone can become lighter than they are now, and they can easily become strong.

Researchers say that if the Earth's current rotation rate were about 17 times that of today, then a day on Earth could be less than one and a half hours. If time flies, we will redefine time, such as how long is a year, and so on. <>

In addition, if the Earth's rotation speed is about 17 times that of today, the centrifugal force and gravitational force near the equator will reach a state of equilibrium, which means that the matter near the equator will not be controlled by gravity and can even fly. The Earth's existing atmosphere will also disappear, so the Earth will be exposed to space radiation at that time, and the Earth will no longer be a habitable planet, and the situation may be worse than the current situation on Venus.

If the Earth's rotation speed is about 20 times the current rotation speed, then the Earth may have disappeared, and with the extremely fast rotation, all the material on the earth's surface will be disintegrated until the Earth falls apart, becomes fragments, and scatters into space. What is the reason for the gradual acceleration of the Earth's rotation?

There is no definitive answer, but some have suggested that there may be some link to the greenhouse effect.

There are still 24 hours in a human day, and the acceleration of the earth's rotation only accelerates the change of day and night, and does not affect the change of time.

There will still be 24 hours. It's just that if you calculate the speed of the earth's rotation, there is none. The speed of rotation has increased, logically not, but we still have 24 hours to go.

Yes, there are no more than 24 hours. As the Earth's rotation speed increases, it no longer takes 24 hours for the Earth to rotate around on its own.

It seems that there is no such thing, although it is said that the rotation has accelerated, but it does not seem that people's work and rest have been shortened because of this.

During the Spring Festival, do you feel that time flies like electricity? In fact, scientifically speaking, 2021 will indeed be slightly shorter than previous years.

As a member of the vast universe, whether the Earth rotates or rotates, it will be affected by interstellar forces, and will adjust in continuous acceleration and deceleration. For the moment alone, the Earth's rotation is accelerating, which means that the day is getting shorter.

Professional data shows that time is passing faster now than at any time in the past half-century. This is because the Earth's rotation rate is the fastest in 50 years. Dou Zhong, a science popularization expert and secretary of the Party Committee of the National Time Service Center of the Chinese Academy of Sciences, said that relevant scientific research has found that since the middle of 2020, the Earth's rotation rate has shown an accelerated trend.

The Earth's rotation rate is faster than ever, can it mean that the year will pass faster? It starts with the measurement of time. The basic unit of time measurement is the second, and then there are milliseconds, microseconds, nanoseconds, and so on.

Today's high-precision atomic clocks for measuring time have reached the sock-sensitive attosecond level, which is minus 18 seconds of 10 (10 18). How short? In short, it's very short, the kind of short that the human senses can't detect.

Since the 60s of the 20th century, high-precision atomic clocks have been recording daily hours with ultra-high precision. When the researchers observed atomic clocks, they found that in the past 50 years, the time it took for the Earth to complete one rotation was rarely less than 24 hours, or 86,400 seconds. Today, however, the length of a day is shorter than 86,400 seconds.

Dou Zhong said that according to a recent report in the United Kingdom, researchers found that July 19, 2020 was milliseconds shorter, becoming the shortest day on record. Such subtle differences, although not reflected in people's daily lives, can have an important impact on communications, electricity, navigation and other fields.

So, what is the reason for the rapid transformation of the earth? It may be related to changes in the morphology of the Earth's surface. Just as a figure skater or ballet dancer makes a twist and turn, the faster the body gathers, the faster the Earth's rotation becomes faster as matter gathers more centrally.

Taking global warming as an example, when glaciers and ice sheets melt and flow into the oceans, the earth's mass is redistributed, and matter is closer to the center than before, so the earth's rotation will become faster.

But the key is that the change in the shape of the earth's surface is only temporary after all. In the long run, the general trend of the Earth moving slower and slower will not change. Dou Zhong said that because of the gravitational effect of the sun and the moon tides, it is equivalent to tapping the "brake" for the rotation of the earth.

And if the slowdown reaches a tipping point, the world's timeworkers will have to kick in on the "leap second" trump card. Of course, that's another story.

Because the gravitational pull of the Earth has decreased, and it belongs to the Milky Way, the core of the Earth is constantly changing.

Because of the influence of interstellar interactions, the earth is constantly adjusting according to the laws of operation, and in recent years, the speed has become faster and faster, so it will rotate faster.

This is normal, everything in the world is constantly changing.

People are also thinking about what is really responsible for the acceleration of the Earth's rotation, and these small differences are what scientists have discovered through atomic clocks.

The Earth's rotation has accelerated in less than 24 hours. Regarding the question of why the earth's rotation is accelerating, relevant scientists have not found out the real reason, and it remains to be done.

Since 2020, the speed of the Earth's rotation has suddenly accelerated, and you know who stole our time? Scientists have recently found that the Earth's rotation has reached the fastest speed in 50 years, which means that our day is less than 24 hours. We all know that in addition to revolving around the sun, the earth also rotates, and one revolution is equal to a year, and one rotation is equal to one day has passed.

But since 2020, this immutable law has been broken, and the Earth's rotation time is one second less than 24 hours, so some people have proposed to remove this difference by one second. to ensure that the clock and the Earth's rotation are consistent. According to the data, July 19, 2020 is the shortest day of the Earth's rotation, and on this day, the Earth's rotation is a full millisecond less than 24 hours.

At first glance, it may seem like nothing, but in the long run, the shorter the rotation time of the earth becomes, the greater the centrifugal force will become, so that the gravitational pull of the earth will become smaller, which means that we humans will become lighter. So what is the reason for the sudden acceleration of the Earth's rotation? It has been suggested that the Earth's self-transformation may be due to the greenhouse effect, which is accompanied by global warming, melting glaciers, and rising sea levels, which leads to the redistribution of the mass and volume of seawater.

As the Earth is affected by this change, its rotation speed will continue to increase. In fact, this kind of change is difficult for us ordinary people to notice, and we don't leave work early. Nor does the weight become lighter, and this change can only be detected by atomic clocks.

The atomic clock is a very accurate timekeeping device, which can be accurate by 20 million light-years by one second. And it is because of the accuracy of the atomic clock that our aerospace field has a high-precision timing service system.
