Why is the night before dawn the darkest?

It is indeed darker before dawn than the rest of the night. There is a scientific basis for this.

First of all, how does the light in the sky come about? It turns out that the sunlight shines on the atmosphere during the day, and the air molecules in the atmosphere and the dust floating in the air scatter them, resulting in bright light. Without the scattering of light by the atmosphere, we would never see light.

In a spaceship, the space around you is pitch black, and that's the reason.

So why is the pre-dawn Earth so dark? It turns out that the distribution of air molecules and dust on Earth is not the same. There are more air molecules and dust near the ground, and less at high altitudes.

Before dawn, the sun's rays shine on the 30,000-kilometer sky, where the air is thin and the scattering effect is weak, so the sky is not "bright" at this time, and people can only see the Milky Way shining. As the earth rotates, the sun's rays shine outward. When the sunlight penetrates into the air at an altitude of 2,000 to 3,000 kilometers, it scatters a very faint light that cannot reach the ground, but dilutes and drowns out the starlight.

At this time, the first starlight in the sky was gone, and there was no light on the ground, so it became pitch black, and I couldn't see my fingers. So, the moment before dawn was darker than the rest of the night.

"There is always a time when it is darker before dawn.

Astronomical morning light occurs when the center of the Sun is above 18 below the horizon.

So the day before sunrise began to dawn.

If the concept of "before dawn" is that the sun is 18° below the horizon, it is basically correct.

There is scientific truth to this, but I forgot what happened, it seems to have something to do with the refraction of light by the atmosphere.

All I know is that before dawn is the coldest.

The darkness before dawn brings out the beauty of the dawn at dawn.

Hehe: That's just my personal opinion.

It was exactly 5:47 a.m., and it was still dark outside, and the roosters raised by the farmers were already crowing. This time period can neither be called night, nor can it be called morning, but it is a little early to call dawn, and it is called the night before dawn for the time being.

Every day is from black to bright, to white, so that the days will pass slowly. Many people are still asleep, while sanitation workers have already started working by street lights, and some workers have also started their day's journey. The little girl upstairs is a high school English teacher, and it is very hard to go out to work at about this time every day.

This also reminds me of when I was in school, every day in order to memorize more books, before dawn, the classroom door would not open, so I would get up and run to the corridor to read by the faint corridor light, and those who don't like to study must be the last to arrive in the classroom, but I have been reading for nearly an hour! And this time period is also the beginning of the gap between classmates.

The plan of the year lies in the spring, and the plan of the day lies in the morning. After work, we gradually have a gap. Some people are industrious and can work, and some people are lazy, although the days are the same, but the use is different, and the results are not the same.

Dawn is a kind of hope, like a lighthouse, the one who gives the sea illuminates the way forward, and also illuminates the direction of the day.

I am a person who does not like to sleep, and many times I will wake up before dawn, silently observe the dark night of the city, listen to the sounds outside, and my thoughts are full of emotion. People who also live in the city, some people live hard, some people live easily, and the darkness before dawn is the hope that each of us has.

Since the height of the angle between the Earth's rays and the sun's rays is the lowest after the sun's westward setting and the time before dawn (i.e., before dawn), the reflection and scattering of sunlight by the atmosphere during these two periods are the weakest, and therefore the darkest periods.

From the darkness of the night to the darkness before dawn, there is a phenomenon of pre-dawn darkness. Because of the darkness before the dawn, the tomato knew that the dawn was so beautiful.

Perhaps after the most difficult experience, the dawn will be the most beautiful, the beauty of the dawn and the darkest form a sharp contrast, indicating that the most terrible time will also come, people are fierce to observe the life is also the same, are after the wind and rain to see the rainbow, if you want to be comfortable, I am afraid that you have to fight.

According to atmospheric science, at night, because there is no direct sunlight, the sky is in a dark state, and if there is a little bit of light, it is because the air molecules or tiny particles in the atmosphere reflect and scatter sunlight.

I once heard the saying, "You will never discover a new continent without a long time of lonely drifting on the sea." ”

Probably many people have experienced such times. It's like drifting alone in a sea area, not knowing when the next wave will come over, and I don't know when I will be able to land, so I can only survive.

The darkness before dawn has passed, and life can only make things difficult for you for a while; Unless you disarm and surrender, your downcast state will last for a lifetime.

Many things are not insisted on because there is hope, but there is hope for persisting in doing them. So, don't give up. If you persist for a while longer than others, you may have one more chance; A little more persistence than others may result in more gains.

When you encounter difficulties, please overcome them firmly. Those who can withstand the beating of fate are the real winners in life.
