Since the stars in the sky are shining, why is it dark at night?

Many people will wonder, since the stars in the sky will shine, why is it dark at night? Bian Xiao looked up some information on the Internet and found that there were various statements. The ancients often thought that the actions of night immortals guided the continuous development of science and technology, and people's cognition also developed accordingly. They put forward the corresponding theory of celestial movement, and people also understood why a day is made up of day and night. People observed the universe and found all kinds of stars around the earth.

It is also found that the earth rotates once every 24 hours, and the earth will mainly rely on sunlight and its energy during the day. There are day and night on the earth, and people gradually form a certain routine, that is, work during the day and rest at night. Many people think that every star has energy, but the sun has high energy, so it masks the light of other stars. Where there is sunlight, people will feel very bright, and where there is no sunlight, people will feel darker.

If people have the habit of observing the night sky, they will find that the moon is shining and its shape will change accordingly. The stars people see are actually far away from people. Stars that used to glow and give off heat become less bright after a long time. The distance between the sun and people is 65.438+0.5 billion kilometers, which means it takes 8 minutes for the light from the sun to reach the earth. The universe is far wider than people think, so people can't imagine the distance between stars and people.

Many people have another view that if a star dies, its light will continue to spread. Many people think that people can receive light from dying stars in the dark. People themselves have certain limitations. If the light is too dim or too bright, people can't see clearly. In any case, there are many mysteries in the universe, which are worth exploring. I hope that scientists can give an exact explanation for this and that human beings can continue to develop.
