Why can you see so many stars during the day? 5

Dizzy. Because the stars are inherently in the universe. It's not at night, it's not there during the day!

It's just that human beings can't see them because they have the sun's rays during the day, and they are too dazzling! But sometimes it can be seen in some cloudy conditions, and sometimes it may be due to the light. You can see the good weather!

But that's rare!

I guess it depends on what you mean by "daytime".

If it means that the sun rises to the time it sets, it is visible for a period of time after it rises or before it sets.

If you want to divide it from the time, then you can't divide it, the day is different all year round, otherwise how can there be summer and winter solstice?

If you judge from the brightness of the sky or something, it is not necessarily, cloudy and sunny days are different.

So, it's not very strange to see stars during the day.

It's your eye problem! Venus.

If you hadn't been beaten, you would have been starved.

It's just dreaming.

Otherwise, it's a solar eclipse.

Venus and Mars can do it, but nothing else should be.

Can you see the stars during the day? And a lot? How come I never saw it? Have problems with my vision?

During the day, it seems to be invisible to the naked eye.

Is it a mistake in the submission?

It's not a brain teaser.

What a thunderous man. Do you have special abilities?

On our planet, there are generally no stars during the day, and that's because of the Earth's atmosphere.

Tricky, it scatters sunlight in all directions, and the stars are so faint that they are hard to show. But this does not mean that during the day there are no stars above our heads. In fact, during a total solar eclipse.

Within a few minutes when the sun is completely blocked, the stars will twinkle as if they were at night. Another example is whether it is in the space shuttle.

The astronauts on the space orbital station, because they were freed from the fetters of the atmosphere, they saw the starry sky in the sunny daylight. Since the sun is still impossible to look at, because there is no air around, there are stars competing not far from the sun. As a result, the daytime they see is completely different from that on the ground.

The light emitted by the stars that can be seen by the naked eye was emitted a long time ago, and this is because it takes time for light to travelBut some people have questioned how much time it takes for light to travel so fast. Obviously, this kind of problem does not take into account its distance, if it is a planet around the Earth, and the light they emit reaches the Earth, it may not take much time, but if it is the Milky Way.

What about planets beyond? The time it takes is a long, long time, according to scientists.

It is speculated that the stars that people see at night may be the light emitted by the planet tens of thousands of years ago, and the speed of light is so terrifying, it will take tens of thousands of years, so the distance is needless to say. In fact, it is possible that some of the stars that humans see every night have even ceased to exist. <>

As we all know, the important way for human beings to obtain information from the outside world is the eye, and the reason why human beings can see things is because the light emitted by things reaches the photoreceptor cells of human eyes. To reach our eyes from the stars, we need to cross a long cosmic space, and the farther away from the earth, the longer it takes for the stars to reach the eyes of humans. Generally speaking, the stars seen by humans are generally stars and are within the Milky Way, while stars outside the Milky Way are too far away from the Earth and too weak in light to be seen by the naked eye.

Therefore, the stars seen by human beings are the history of the stars, that is, the past of the stars, and as for the current state of the stars, human beings cannot be sureBecause they are too far away from the middle of the earth. Not only does light take time to propagate, but gravity also takes time to propagate, sunlight.

It takes eight minutes to walk to Earth. So if the sun is gone now, humans will need to know it after eight minutes, and they will be able to feel the disappearance of the sun's gravity, and if it is daytime, humans will have eight minutes of daylight. <>

Obviously, light travels fast, but its speed is insignificant compared to distance.
