The time it took for the earth to rotate once was defined as a day. To be precise, it was 23 hours, 56 minutes and 4 seconds, but people usually counted a day as 24 hours. However, the Earth's rotation speed was gradually slowing down, mainly due to the influence of the Moon's tidal force and other factors. Although this change was extremely small, in the long run, the length of a day was slowly getting longer.

" Perfect World " was a fantasy novel written by Chen Dong. It had a total of 2015 chapters and 6,587,500 words. It started on August 16, 2013 and ended on August 4, 2016.

At present, the Earth's rotation period had shortened by an average of 0.5 ms. Although a day was less than 24 hours, it was still far from being as short as 23 hours and 15 minutes. The acceleration of the Earth's rotation speed was a relatively slow process, and in the long run, the overall trend of the Earth's rotation was to slow down. When the Earth was just born, it took about 6 hours to rotate once. During the dinosaur era, it took about 23 hours. Now, it was basically close to 24 hours. In the next hundreds of millions of years, it might reach 25 hours. Therefore, the actual day was not 23 hours and 15 minutes.

Currently, the duration of a day was about 24 hours (23 hours, 56 minutes and 4 seconds to be precise). However, judging from the slow deceleration of the Earth's rotation speed, the length of a day in the future would gradually become longer. For example, in 200 million years, there would be 25 hours in a day, and in 1 billion years, there would be more than 30 hours. Therefore, it could be considered to be 24 hours at most. The novel "Ten Years of Death" is equally exciting. Everyone is welcome to click and read it!

Based on the current level of scientific knowledge and technology, it was impossible for people to return to a few hours ago. Although the theory of relativity proposed some theoretical possibilities to travel to the future (for example, time would slow down when moving close to the speed of light), there were many theoretical obstacles to going back to the past. For example, the arrow of time theory showed that time could only flow forward, and it could also produce logical contradictions such as the "grandfather paradox." Although scientists have been exploring the possibility of time travel, they have yet to find a way to go back in time (including a few hours ago).

Long ago, in the evenings, families would gather around the fireplace and tell stories or play simple games as there was no electricity.

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.
