If you want to ask everyone what is the most precious thing in life?
I believe that everyone will give different answers, but among the many answers, "time" will definitely occupy a corresponding proportion.
Nothing else, just because for us humans, no one can travel through time and space. What has passed has passed, and it will never stop temporarily because of a certain person or a certain thing.
In modern society, although we already have countless tools to "see" the existence of time, when facing time, everyone's attitude will still be different.
The British " Daily Mail " once pointed out that in the past fifty years, every day has been longer than twenty-four hours. However, what many people don't know is that since 2020, has The rules were gradually broken.
There are less than twenty-four hours in a day, what does this mean? Next, let us take a look at what impact the earth's rotation will have on humans after it accelerates its rotation. What is the time of
and what is the time of
? In fact, the simplest understanding of is a measurement used to describe changes. Without changes, there would be no time .
Before the emergence of microscopic physics, this has always been a recognized truth.
But with the progress of human scientific civilization, people gradually discovered that this principle does not seem to be completely feasible.
The rotating clock
To give a simple example, in the microscopic world, photons have changes but no time.
This makes people confused. If everything in the microscopic world is enlarged, does time really still exist? Are the tools we have used to describe and record thousands of years of history in vain?
Photons in the microscopic world
In fact, if you analyze the nature of time, without sufficient understanding of the theory of relativity and quantum mechanics, the complexity is enough to make people numb.
But human beings are always smart and alert. We don't need to analyze the essence of time. What exactly is, we only need to know how to use time to help human life.
For this reason, the ancients invented the most primitive method : "Work at sunrise and rest at sunset." As long as there is light shining, people will work hard, and if there is no light, they will rest.
With the development of the times, the changes in the sun's shadow helped humans design and create the sundial , and also successfully allowed the ancients to invent the time.
The sundial, a timekeeping tool invented by the ancients
In modern society, human civilization and science and technology have become more and more advanced, and the calculation method of twenty-four hours a day is also widely known.
Many people may not understand why is a twenty-four-hour format and is used. In fact, this is mainly related to mathematical calculations.
In short, time appears like this and accompanies us day and night, in visible or invisible places, it never stops and never gets tired.
What does it mean when there are less than 24 hours in a day?
As the "Daily Mail" said, in the past few decades, every day has been more than 24 hours.
The main reason why humans have not discovered it is that the extra time unit is completely based on milliseconds.
This is like a grain of sand suddenly appearing in the desert. Naturally, it is difficult for anyone to observe it.
The vast Sahara Desert
But after 2020, each day will gradually become less than twenty-four hours, and suddenly there is a grain of sand missing in the desert. What will this mean?
Regarding this, the best way to understand this is to analyze it from the changes in force .
Anyone who understands the rotation of the earth knows that the earth's own motion is divided into two types, one is continuous rotation on the axis of rotation, and the other is revolution around the sun.
If the rotation time becomes shorter, it means that the earth's centrifugal force gradually becomes larger, while the gravitational force gradually shrinks.
Simulate the rotation of the earth
Regarding this point, it is actually very easy to understand.
If you have a globe at home, you might as well do an experiment with it. When the globe moves slowly, the objects placed on the globe will not actually have much impact.
But if the globe moves faster, objects placed on it will naturally fall off more easily.
Compact globe
Back to the earth itself, the time of each day is now shortened, which means that the influence of gravity on human beings is also gradually decreasing.
The main reason why we don’t feel anything yet is that a grain of sand in the desert is too small.
But even so, one second may not have much impact on the lives of ordinary people. .
But for the scientific development of cutting-edge fields , the impact is very serious, especially in the aerospace field, where a tiny error may lead to the failure of related experiments.
This situation is just like the two protons in " three-body ". Although they are small, they can affect the progress of human civilization.
Protons are tiny
More importantly, what if this phenomenon continues? When gathers sand to form a tower of or sand gathers to form a sandstorm, how will the human world change?
In this regard, scientists have speculated that if the earth's rotation speed becomes more than 24 times faster than today, that is, the earth's rotation time will be less than an hour every day.
The restraint of gravity on human beings has been minimal. Around the equator, we can even fly at will.
Some people may think, isn’t this good news for humans who have been pursuing flight for thousands of years?
Scenery around the equator
Yes, this is not good news, but a disaster .
When humans can fly at will, all objects on the surface of the earth can also "fly at will".
Take the ocean as an example. At that time, the easiest thing for humans to see is the huge waves that let loose.
Tsunami
In outer space, when the earth's gravity cannot bind the atmosphere, we humans will also face the radiation from the universe.
In such a celestial environment, it is far more difficult for humans to survive and continue their civilization than we imagine.
Cosmic rays from the depths of the universe
Fortunately, at present, the changes in earth's time observed by scientists only speed up the time by about one second.
will not have much impact on the earth or humans, but this will inevitably make people worry about whether time will become faster and faster in the future development. How is the tiny time difference of
discovered?
How did scientists discover such a small change? There are countless gravels in the desert, and it is impossible for scientists to count them one by one.
In fact, regarding this issue, we have to mention the atomic clock in modern society. It was through the observation of subtle changes in the "atomic clock" that this feature was finally discovered.
Many people may be unfamiliar with the atomic clock. In fact, it is a very precise timing device.
Especially after the atomic clock was upgraded again in 1967, it may take up to a million years for the atomic clock to have an error of less than one second.
Atomic clock
The main reason why it can do this is that the principle of atomic clock is to rely on the electron waves emitted when atoms absorb or release energy to keep time.
Under this extremely stable situation of electromagnetic waves , scientists designed a series of precise instruments to control them, and the atomic clock naturally appeared and became the authoritative representative of time calculation.
Therefore, after scientists discovered that the time on the atomic clock is one second shorter than the twenty-four hours in our daily impression, we have reason to believe that in real life, our daily lives are also shorter. One second.
Books and time
The reason why there are less than 24 hours in a day
After understanding the above-mentioned relevant situations, we can't help but think, what is the reason for this situation?
According to the answer given by the Institute of Chinese Academy of Sciences in the interview, we learned that the earth's time is getting faster, that is, the earth's time is less than an hour, and we need to find the reason from the changes in the earth itself
The melting glaciers
And the final results prove that, In fact, global warming is the main force behind all this.
But after the polar glaciers melt and advance towards low latitudes, the angular momentum changes in this circle eventually affect the angular momentum of the entire earth, and the rotation is also affected to a certain extent.
Although at present, this impact does not seem to be significant, if we continue to allow global warming to occur.
The Earth’s rotation
No one can imagine how the Earth’s rotation speed and gravity will change when the Earth’s angular momentum sphere undergoes huge changes...
