How fast do you have to run after the sun to keep it daytime? What is the scientific basis for this?

With the continuous development of science and technology in this society, people have great curiosity about more and more scientific and technological things, and some people have a certain curiosity about how many miles they travel per minute to chase the sun, which leads to some people to look for such truths, so some people have such questions:How fast do you have to run after the sun to keep it daytime? What is the scientific basis for this?

In fact, there are a lot of myths and legends in China, but these myths and legends are only a fantasy in ancient times, and have not been concretely realized, such as the Kuafu chasing the sun that we know, but with the continuous development of this technology, people have been able to use the current scientific theory to calculate how much this speed needs to run to be able to see all the daytime, we take the equator to calculate, as long as the speed reaches 465 meters per second, it can always be daytime. <>

In fact, people have already got a correct answer to such a question, but because the current technology has not yet reached such a level, so no one can see the day, but it is very good to have such an idea, because it can prove that we human beings are constantly moving forward, and not staying in the same place. <>

Presumably, one day in the future, our technology will reach such a level that we will be able to move at a speed of 465 meters per second. In that case, we can see all the time, it is daytime, and we have completed the ideal concept of Kuafu chasing the sun, which can also prove that our scientific and technological level has reached another height, with such a speed, we can go to the universe to explore, find a new continent in it to find more resources, so that we human beings can use it for a long time, forever survival.

As we all know, the earth revolves around the sun, from which the four seasons are formed, and the earth is autobiographed, from which day and night are formedThe sun can basically only shine half of the earth, and the intersection of night and day is called the morning and dusk line, and the morning and dusk line is at different latitudes, its speed is not the same, generally speaking, the morning and dusk line is the fastest at the equator, and the slowest speed in the polar region, which may be equal to zero, taking the summer in the northern hemisphere as an example, the top area of the North Pole has been in the daytime, and this also means that if you want to pursue the daytime in this area, you don't need to walk, but if it is in the equatorial region, If you want to stay in the daytime all the time, the minimum speed must also catch up with the speed of the morning and dusk line, which is 465 meters per second. <>

As the name suggests, the function of the morning and dusk line is to separate the day and night, but this is only its superficial meaning, and the role of the morning and dusk line is many. For example, it divides the equator in two, so that the day and night on any day on the equator are of equal length, and the point on the line of morning and dusk is parallel to the height of the sun.

Since the earth is a sphere, the morning and dusk line is not a horizontal straight line, it is a circle, that is, half of the circle is day, and the other half is night, so if you want to keep yourself in the daytime, you have to catch up with the speed of the morning and dusk line. <>

If you want to trace the day at the equator, you need to move at least 465 meters per second, and everyone knows that the speed of sound is only 340 meters per second, which means that if you want to reach the speed of the morning and dusk line, you must exceed the speed of sound. With the advancement of technology, although it is entirely possible to achieve 465 meters per second, it will not last, after all, there is no technological thing that does not need energy to run on its own. Therefore, it is absolutely impossible to surpass the dawn and dusk line by human power alone, and even with the help of technology, it cannot surpass the speed of the morning and dusk line for a long time.

Overall, the idea of staying in the daytime is good, and of course, it is possible to go to the Arctic, but in the case of the equator, it is almost impossible.

More than 3000 km h. Because the circumference of the earth is about 80,000 kilometers, and the rotation is 24 hours, the speed must reach more than 3,000 kilometers and hours to be daytime all the time.

Running at 465 meters per second on the equator is always seen in the daytime, but technology has not yet reached such a level.

The linear velocity of the Earth's rotation at the equator is about 465 meters per second, and if this speed is maintained at the equator, chasing the sun westward, it will always be in the daytime.

Of course, the premise of this conclusion is to start chasing the sun at the equator of the earth, if you go to the North Pole in the summer of the Northern Hemisphere and the South Pole in the summer of the Southern Hemisphere, you will always be in the daytime, and you will not even have to run, you will always live in the daytime, which is what we call the polar day phenomenon.

This story reminds me of the mythical character Kuafu in the "Classic of Mountains and Seas", Kuafu is a giant who is good at running and wants to keep the sun and run with the sun, drank the water of the Yellow River and the Wei River, or died on the way to find water, and finally the crutches in his hand turned into a peach forest, and the body turned into Kuafu Mountain, although Kuafu chasing the sun is not self-sufficient, but it symbolizes the desire of human beings for the unknown world, and with the progress of science and technology, we also have the speed to catch up with the sun.

Exceeding the speed of light can always be daylight. At present, the speed of light is the fastest speed, and no technological means can exceed the speed of light at this stage.

About 465 meters per second, because the Earth is an opaque sphere, it has to keep up with the Earth's rotation speed during the day.

I think you just have to keep moving as fast as the sun or the earth moving, so you can always see the sun.

To be daytime all the time, you have to exceed the speed of the Earth's rotation. Then you'll have to go over 465 meters per second to keep up.

According to scientific calculations, the linear velocity of the Earth's rotation at the equator is about 465 meters per second, and as long as this speed is maintained at the equator, it can always be in the daytime if it chases the sun westward.

This problem depends on the latitude of the earth, in the South Pole or the North Pole there are polar days and nights, when there is a polar day, people do not need to run, every day is daytime, if it is the equator, you have to run 40,000 kilometers a day to catch up with the sun.

Theoretically, as long as we keep running towards the sun and the speed exceeds the rotation speed of the earth, we can keep it all the day, but the speed of human beings cannot keep up with the speed of the earth's rotation. The linear velocity of the Earth's rotation in the equatorial region is 465 m s, and to maintain daylight, it needs to run at a speed greater than 465 m s.

As long as you can keep up with the speed of the morning and dusk line, you can always be daytime, the sun shines on the earth, turning one side of the earth into night, and one side into night, due to the rotation and revolution of the earth, different latitudes and longitudes on the earth are in different rays, so keeping up with the speed of the morning and dusk line can always be daytime, and the speed of the morning and dusk line is about 463m s

This can be imagined, the speed of the average fighter is 1,000 kilometers, and some fighters reach 2,000 kilometers, it is possible that this speed will be maintained until it is daytime, if human beings run, it is not practical.

You have to exceed the speed of the Earth's rotation. I've seen a report that says that you can catch up with the Earth's rotation speed if you reach twice the speed of light.

Look there, you don't have to run in the North Pole, it's just two days a year.

It cannot be slower than the Earth's rotation.

If you can keep up with the speed of the twilight line, then you can always be in the daytime, and the twilight line moves at different times of the year at different latitudes and times, with the fastest at the equator being 463 m/s.

We know that the Earth's rotational motion leads to the alternation of day and night, with the Earth being half daytime and half nighttime at any given moment, divided by a changing line of morning and dusk.

The height of the Sun at each point on the twilight line is zero, and the twilight line always bisects the equator, so that day and night are of equal length on any day of the year on the equator; But because the Earth's axis of rotation is not perpendicular to the plane of the ecliptic, the days and nights may vary in latitudes beyond the equator, such as in the Northern Hemisphere, where the days are longer in summer.

So theoretically, as long as we can keep up with the speed of the twilight line, we can stay in the daytime all the time, and the twilight line moves the fastest at the equator, with the value of :

v=40000*1000/(24*3600)≈463m/s；

This is a double of the speed of sound (340m s), which can be reached in a supersonic aircraft.

At high latitudes, the speed of the twilight line will be reduced, and even the twilight line will disappear, and the polar day or night phenomenon will occur locally.

For example, from March 21 to September 23, the North Pole is in the polar day, and it is daylight 24 hours a day, and the South Pole is in the polar night.

At high latitudes above 60°, if the civil aviation flight we take happens to be flying from east to west, then theoretically we can catch up with the moving speed of the morning and dusk lines.

In the solar system, Venus has the slowest rotation period, with a rotation period of 243 Earth days, and its orbital period is one Earth day, which means that a day on Venus is longer than a year; On Venus's equator, the dawn and dusk line moves at a speed of only meters and seconds, which is the speed at which a person would normally jog.

On Earth, you have to travel at a speed of 20 kilometers per second to be able to stay in the daytime state, which is the speed at which the sun moves.

On Earth, a speed of at least 36 kilometers per second must be maintained to maintain it during the day.

Since the Earth is a sphere, and the Earth is always orbiting the Sun, no matter how fast the Earth rotates, there is always a part of it that is in the dark.

You need to run with the sun at a speed of 463 meters and seconds to stay in the daytime.

In a sense, if you follow the sun all the time, then it may be daytime all the time, but in specific circumstancesThis is definitely in the theoretical situation to keep running with the sun, then there will be always light, this is what we call daytime, but whether it has always been the day we think it is, but also from the following aspects. <>

1. If you keep running with the sun, then there will always be light in front of you. In fact, for us, if we have been simply following the sun, then we will be under the light of the sun at this time, so for ourselves, we are always in a state of light, which is what we call daytime, so we have been in the state of daytime. <>

2. Theoretically, if you simply follow the sun, then you can always be daytime. In fact, the definition of day and day and night itself is based on the sunlight, so if there is no sun, then this time is night, but relatively speaking, if you keep running with the sun, then there will always be the sun, so it is always day. <>

3. In fact, even if you follow the sun, sometimes it may not be daytime. In fact, if in a sense, if you throw out some special circumstances, then you have been running with the sun, theoretically it has always been daytime, but it is not excluded that some special circumstances, this is definitely not daytime, since it is a hypothesis, then there may be some special situations at this time, so if it has been running with the sun, but you can't see the sun's rays, then this time is not daytime.

Generally speaking, if we keep running with the sun, then it must be daytime all the time, but from a macro point of view, if we simply follow the sun, then what we see is the sun, so it is daytime, but if the sun is blocked by the occlusion and cannot see the light, then what we see at this time is the night.

No, because the sun will always set, unless you run faster than the sun sets.

Theoretically, we can keep the day as long as we keep running towards the sun at a speed faster than the Earth's rotational speed. The linear velocity of the Earth's rotation at the equator is 465 m s, and as long as it exceeds this velocity, it can remain daylight.

Theoretically it is possible to do it, but in practice it is not possible because you will encounter mountains, you will encounter the sea, and the speed will not keep up.

Every point on Earth can catch up to the day at a different speed. Taking the equator as an example, it needs to reach 463m s. Day and night are the causes of the Earth's rotation, and as long as the speed of the Earth's rotation is reached, the Sun can be seen all the time.

The day-night cycle is due to the rotation of the Earth. The linear speed of the Earth's rotation near the equator is about 400 meters per second. If you can keep up with the speed of the Earth's rotation. Not all day is daylight.
