the reason he sleeps less than three hours a day

In recent years, Cai Zhizhong's sleeping habit was to sleep three to four hours a day. He usually got up at 1 a. m. and worked until the employees went to bed after work in the afternoon. His habit of short sleep might be related to his unique lifestyle and his understanding of the value of time. He paid attention to the completeness and cohesiveness of time, believing that a large period of time would help him to devote himself to his work more deeply and attentively, thus exerting greater value. However, this short sleep habit was a special mode that Cai Zhizhong had developed over a long period of time, and it might not be suitable for everyone.

Since the middle of 2020, the Earth's rotation rate has been accelerating, and the rotation speed has reached the fastest speed in the past 50 years. This resulted in less than 24 hours in a day. Although there was no 100% definite answer to the reason for the rapid change of the Earth, some people pointed out that it might be due to the greenhouse effect. Through modeling and analysis, global warming and melting glaciers caused the seawater to warm up and expand. The sea level rose, and the mass and volume of seawater were redistributed. This change affected the Earth's rotation speed, thus breaking the 24-hour rule. The acceleration of the Earth's rotation speed would have a series of effects, such as the centrifugal force of the Earth becoming larger and the gravitational force becoming smaller. This would allow humans to become lighter on Earth. If the Earth's rotation speed increased to a certain extent, such as reaching 17 times the current speed, it would take less than one and a half hours for the Earth to make a circle. Time would pass quickly, and the concept of time would be redefined. Moreover, objects near the Earth's equator would no longer be controlled by weight and could easily fly. It was the same in other places. However, at the same time, the Earth's climate and ecological environment would change drastically. The seawater would no longer be bound, and the Earth's atmosphere would disappear. The Earth would suffer from the " indiscriminate bombardment " of space radiation and would no longer be habitable. If the rotation speed reached 20 times the current speed, everything on the Earth's surface would gradually disintegrate and fly into space. The Earth might disappear. However, the current change in rotation speed was very small, only in the order of millimeters. Although the time synchronization between the low-Earth orbit satellite and the ground would not match, the active correction system in the satellite system could solve this problem, so the vehicle navigation and daily life on the ground were not affected.

The so-called day was 24 hours, which was the time it took for the Earth to rotate once. It was also calculated according to the sun's day. It was one day when the Earth rotated to the same position as the sun. However, in terms of the exact length of the Earth's rotation, its cycle was about 23 hours and 56 minutes. At the same time, under different circumstances, the length of sunlight in a day would be different. For example, during the winter solstice, there would be about ten hours of sunlight during the day, and during the summer solstice, there would be about sixteen hours of sunlight during the day. In addition, in some specific concepts, such as the time-limited eating method of intermittent fasting, the time of eating in a day would be limited to a few hours, and the rest of the time would be fasting. However, this did not change the basic definition of 24 hours a day.

Since the middle of 2020, the Earth's rotation rate has been accelerating. The rotation speed has reached the fastest speed in the past 50 years, which makes a day less than 24 hours. For example, on July 19, 2020, the Earth completed its rotation 1.4602 ms ahead of schedule, the shortest day in recent years. The magnitude of this self-transformation was very small, only in the order of millimeters. It mainly affected the time synchronization between the satellites in low-Earth orbit and the ground. However, due to the active correction system of the satellite system, the navigation and daily life of the ground vehicles were not affected. However, if the Earth's rotation speed continued to accelerate, according to scientists 'speculation, it would cause gravity to weaken. The objects on Earth would easily float up, and the oceans would become very active. Tsunamis might occur frequently, and the living space of human civilization would be compressed to the inland areas. If the Earth's rotation speed increased to 20 times that of the Earth, the " centrifugal force " generated by the high-speed rotation would scatter the Earth's materials, and human civilization would disappear.

Currently, the length of a day on Earth was about 24 hours (23 hours, 56 minutes, and 4 seconds to be precise). Although the length of a day on Earth had changed in history, and due to tidal forces, it was still slowly increasing at a rate of about 1.7 ms per century, it had not yet reached 25 hours.

According to the current international time measurement standard, a day was 24 hours. However, from a scientific point of view, the Earth's rotation speed was changing extremely slowly, which might cause the length of a day to change after a long geological period. However, under the current normal time system, a day was 24 hours, not 25 hours.

In the natural state of Earth, a day was currently about 24 hours. However, judging from Earth's historical development, the length of a day was not fixed. About 4.5 billion years ago, when the Moon was first formed, a day on Earth was less than 10 hours long. Later, as the tidal force of the Moon gradually slowed down the Earth's rotation, a day became longer and longer. However, between 2.2 billion years ago and 600 million years ago, due to the mutual offset of several tidal forces, the Earth rotated at the same speed for more than 1 billion years, keeping the length of a day constant at about 19.5 hours. Even today, this tidal force continues to extend the length of a day at a rate of about 1.7 milliseconds per century. However, there were no natural factors that made a day 48 hours long. If there were to be a 48-hour day, it might be necessary to assume that there was a huge external force to greatly slow down the Earth's rotation speed or make a science fiction setting, but such a situation did not exist in reality.

According to the conventional time system, a day was 24 hours. There was currently no widely accepted standard time system that included a definition of 25 hours a day. This statement may be made under specific assumptions, science fiction concepts, or special situations (such as discussing changes in the Earth's rotation speed), but from the perspective of the existing general concept of time, a day is usually 24 hours.

Although the Earth's rotation time was slightly longer than 24 hours, about 23 hours, 56 minutes, and 4 seconds, based on human time measurement and social activities, we usually defined a day as 24 hours. In history, this method of timing could be traced back to ancient Egypt and ancient Babylon. At that time, people used sundials to divide day and night into 12 hours. As time passed, even with more accurate measurement methods, they still maintained the habit of 24 hours a day. In addition, in order to make time measurement more accurate and stable, international standards introduced Coordinated Universal Time (UTC), which maintained synchronization with the Earth's rotation by inserting leap seconds when needed to ensure that time measurement was consistent with the Earth's natural movement. Since the middle of 2020, the Earth's rotation rate has been accelerating, which means that there are less than 24 hours in a day, but this doesn't affect our usual habit of definition of a day as 24 hours. Therefore, 24 hours could be considered as a day.
