The Earth suddenly accelerates its rotation speed? Our common "home", the Earth, has existed in the universe for nearly 4.5 billion years. As a planet in the solar system, the Earth has been rotating around the Sun and rotating at the same time.
It is because of the Earth's rotation, we have a year of spring, summer, autumn and winter seasons, it is also because of the rotation of the Earth, we have a black and white day and night.
The emergence of human beings to add the ruler of time to the earth, in the endless space for time to appear, the earth gradually appeared a minute, a second, a day, a year concept, we also unspoken that the earth's day is 24 hours.
It is because we know how fast time flies that we cherish every second of the 24-hour day. But recent research has found that the Earth is secretly "accelerating", rotating faster and faster, what will this mean for mankind?
Why does the earth rotate?
When you take a shower, if you have a careful observation of the water flow, you will find that the water is swirling into the sewer, which is the role of the Earth's rotation.
The Earth rotates from west to east on its axis of rotation. As early as the Warring States period in China, there was a thesis that "the left side of the sky is shaped and the right side of the earth is opened", which was confirmed by Copernicus' heliocentric theory in 1543. The main reason for the rotation of the earth is the imbalance of angular momentum produced by "gravitational attraction".
Because of the existence of the Ether in the universe, and the existence of the Ether is huge in scope, and the Ether is always in motion, so the stars in the universe are affected by the force of the Ether, and the Earth and the Sun are naturally no exception.
The basic processes of the formation of celestial bodies in the universe are also contracted by the influence of gravity, and the solar system was formed by clouds of gas from nebulae under the influence of gravity before it was formed.
When the cosmic dust and gas begin to rotate around a center, the resulting star also begins to move slowly. However, since the angle of contraction cannot be 100% 0 degrees, when the angular momentum deviates, the rotation will start due to friction, and the same principle applies to the rotation of the Earth.
Why does the Earth's rotation become faster?
Will the speed of the Earth's rotation remain stable and constant? The answer is no. In fact, back at the beginning of the Earth's life, the Earth's rotation speed was very fast, only a few hours a day.
It is because of the later appearance of the moon that the strong tidal force has slowed down the rotation of the self sphere and has the present 24-hour day. In fact, if we want to count more accurately, the Earth's day should be 23 hours, 56 minutes and 4 seconds, but people count the day as 24 hours for convenience.
In the 21st century, scientists have discovered that the Earth is constantly "secretly accelerating" itself. According to the results of atomic clocks, which specialize in measuring time, July 19, 2020 was the shortest day on Earth in decades, with time on this day 1.4602 milliseconds slower than usual.
Although a millisecond is not enough for people to notice, but the Earth's rotation speed has become faster, is already an established reality, and there are two main reasons affecting the Earth's rotation speed.
First, the global warming of the climate. According to the survey, because of the impact of human activities, the global warming has been 1.0 degrees Celsius. And scientists predict that if no further intervention is made, the world is likely to rise by 1.5 degrees Celsius between 2030 and 2052.
The effects of global warming are undoubtedly enormous, causing glaciers to melt, sea levels to rise, and strong internal movements of the Earth's crust due to the increase in temperature. The strong movement inside the earth's crust will cause the rotation speed to increase, and will cause large-scale disasters.
As we know, earthquakes are caused by the movement of the earth's crust. According to scientific research, after an earthquake in Japan, the earth's rotation speed has become 1.8 microseconds faster, the human impact on the earth is everywhere.
Second, the moon's constant distance. The Moon, as a satellite of the Earth, undoubtedly also has a huge impact on the Earth. The gravitational coupling between the Moon and the lunar side of the bulge produces a torque on the Earth's rotational motion, consuming the angular dynamics and kinetic energy from rotation in the Earth's rotation.
Such an effect, on the one hand, makes the Moon itself rise to a higher orbit and have a longer orbital period, and on the other hand, slows down the Earth's rotation.
But in recent years, as lunar rangefinder reports show that the Earth-Moon distance is increasing at a rate of 38 millimeters per year, it also shows that the Moon is steadily sneaking away from its otherwise good partner, the Earth. The moon is far away from the earth means that the tidal force for the earth will continue to become smaller, then the earth's rotation speed will naturally become faster and faster.
What will be the impact of the self-shift fast?
The Earth's self-transformation on the one hand will not only cause a shortening of the day, but will also have a huge impact on human technology. As we know, many human high technology need precise time calculation, such as satellite launch, spacecraft into the air need to rely on time to project data.
When the Earth's rotation becomes faster, the time of day changes, which means that all the data have to be overturned and restarted, which undoubtedly has a huge impact on human technology.
Although, the current rotation of the Earth has only become a few seconds faster and has little impact on our daily life. However, through the reason of the Earth's rotation speed has become faster, the effect of human activities on the Earth has been increasingly visible.
Since mankind entered the industrial age, there has been a great deal of environmental damage to the earth, and the impact of such damage has been expanding over the years, causing serious problems such as global warming today. On the other hand, the Earth's faster rotation is also caused by human activities.
Therefore, instead of exploring why the Earth's rotation speed will become faster and what kind of impact it will have on us, human beings should reflect on themselves and focus on the protection of the Earth. The Earth has always been our home and is currently our only home, and only by protecting it can we develop more permanently.
