Everyone knows that the sun rises from the east and sets from the west. Therefore, someone carefully observed during the flight and found that if the plane flies from east to west, the daytime becomes longer, and vice versa, the daytime becomes shorter. Someone made an assumption that if the plane flies westward at a speed of 1,700 kilometers per hour, will people never see the night? I have to say that this idea is reasonable, but there is always a certain gap between theory and practice. Let's analyze it together. Where is this gap?
According to theoretical understanding, the earth rotates from west to east, realizing day and night alternation. Therefore, if the plane is flying from west to east, the day will be longer. However, if it is always daylight, the flight speed of the airplane must keep up with the speed of the earth's rotation. And the speed of the earth's rotation is not uniform. Around the equator will reach more than 1,600 kilometers per hour, but in high latitudes, the speed is only half of that around the equator, which is more than 800 kilometers per hour. At this speed, an airplane can catch up with the Earth's rotation speed at high latitudes as long as it can reach 800 km/h, while at low latitudes it will catch up with the Earth's rotation speed faster. As long as we can keep up with the rotation speed of the earth, we can stay under the sun forever. However, this is only a theoretical statement, which is not the case in reality.
As we all know, airplanes need fuel. When they fly a certain mileage, they need to land and refuel. Moreover, the power of the aircraft also needs rest and overhaul, and it is impossible to start it 24 hours a day. In this way, the airplane cannot fly around the clock, it is impossible to chase the sun forever, and realize the idea that it is always daytime. However, they all say that only unexpected things can't be done. With the continuous development of human science and technology, everything that people think is impossible may become a reality. Whether the power of the aircraft can be increased to the expected effect is still unknown. what do you think about this?
