"Gaze from space? How can it be? ”

Li Mengran: "If you are interested, listen to me slowly." ”

"The whole history of the earth can be seen here. The age of the earth is 4.54 billion years, everything that happens on the earth, will travel to the sky at the speed of light, in the universe, there is a kind of star, called the reflection star, this kind of reflection star, because it is filled with water, will reflect the light from the earth back, as long as you find a reflection star 2.77 billion light years away from us, you can see the first sight of the earth. ”

"By analogy, any historical event can be seen clearly through the reflected stars at the corresponding distance."

Zhang Jingwen: "My God, it's so magical, it's really a wonderful thing." ”

Li Mengran: "Knowing the mirage, that is, the ancient light came to the earth through the reflected stars, and after the refraction of the sea level, people saw the ancient scenery again." ”

"Since you're here, why don't you go and have a visit?"

Zhang Jingwen: "Okay, I just want to see it." We talked as we walked. ”

"What do you mean, everything we do will not go away?"

Li Mengran: "Theoretically, that's the case. Everything we do, in the form of light, or in other forms, will spread to the universe, and it will continue forever, and it will never disappear. ”

"It's just that the capabilities of our telescopes are still limited, and we can only see part of the fragments."

After about ten minutes, they walked to the site of the sinkhole, a large circular crater just large enough to hold a large astronomical telescope, a kilometer in diameter and the size of 30 football fields.

Meng Ran continued: "A radio telescope consists of a directional antenna or antenna array, a feeder, a high-sensitivity receiver and a recorder. Let's go to the monitoring lab and have a look. ”

It is a darkroom, similar to that of a movie theater, with a large screen in front of it, and the information received by the telescope, after processing, can be displayed on the screen.

They sat down, and Xiaowen stared at the big screen, which was chaotic.

Meng Ran debugged it on the console, and there really was a picture.

There are green mountains and green waters in the distance, there is a field of crops nearby, a few old cattle are grazing peacefully on the side of the road, and a pair of young people are sitting on hoes on the side of the road, chatting happily, as if they are a pair of lovers.

They are so laid-back, they still look up at the sky from time to time, what are they looking at? What are you thinking?

Suddenly, a bright smile appeared on the girl's face, and a gaze shot at her, with three points of surprise and seven points of excitement.

"Did she see us?" Xiaowen asked in surprise.

Li Mengran: "How is it possible, it is exactly 2000 years ago." ”

Zhang Jingwen: "It's amazing, it should be 80 AD, the post-Han era, it seems to be the period of Emperor Zhang of the Han Dynasty." ”

Li Mengran turned her face to look at Jingwen and said with a smile: "Huh? Why is this girl's gaze so similar to yours? ”

Zhang Jingwen also smiled: "I think that boy is so familiar, why does he look the same as you?" ”

Li Mengran took a closer look: "It's really a bit like a god." ”

The two of you look at me, I look at you, laughed for a while, and then fell silent again.

Li Mengran frowned slightly, and actually said a few words:

Yesterday's ridge of the field, today looking at the sky cave;

The years have passed for thousands of years, and the eyes have passed through space.

The green mountains are still there, and the love is stronger,

The past is like a past, and I still feel my heart.

……

"Yes, yes, what a poem!" Zhang Jingwen asked again: "Why do people have eyes, but other animals don't?" ”

Li Mengran: "This, I can only explain it with mythological stories. ”

Legend has it that God created men and women and placed them in the Garden of Eden, so that they could plant and watch over everything in the garden.

And he said to them, "You shall eat as much as you like from the fruit of the garden, but not the fruit which distinguishes good from evil, for if you eat of it, you will surely die."

The serpent was the most cunning, and he tempted the woman and said, "Did God really say that you should not eat any of the fruit of the garden?"

The woman replied, "We may eat of all the fruits of the garden, but God has commanded us of the tree in the middle, 'Do not eat of it, nor touch it, or you will die.'"

And the serpent said unto the woman, "This is a lie to you, and you will not die." God commands you this because he knows that when you eat of the fruit of this tree, your eyes will be opened, and you will know how to distinguish between good and evil, just as he did.

When the woman saw the fruit of the tree, which was very lovely, for food and for wisdom, she plucked it and ate it. She also gave the fruit to her husband, who was with her, and he ate it. Their eyes brightened, and they realized that they were naked, so they made skirts out of the leaves of the fig tree and tied them around their waists. ”

Zhang Jingwen thought for a moment and said: "It turns out that it is because I have eaten the fruit of the Wisdom Tree that I have eyes, and my eyes will be bright. ”

Li Mengran: "Yes, but it's just a legend. ”

Zhang Jingwen: "Maybe it's true, I ate fairy fruit in a dream, and it feels so good." ”

Li Mengran: "Really? Dreams are good, but they are not reality. Xiaowen, look at the screen! ”

At this time, the couple happily set their eyes on space, what were they looking at? What is in heaven?

Li Mengran: "People are indeed too small, but they have a pair of deep eyes to despise space. This gaze can penetrate everything and perceive everything. ”

At this point, the signal suddenly cuts off, the image disappears, and the screen becomes chaotic again.

"Good luck today." Li Mengran said: "I haven't received the picture for a long time. ”

I don't know when, Teacher Li Fang was also sitting in the back, and said with a smile:

"Seeing that you were chatting happily, you didn't say hello, hello everyone!"

Li Mengran: "Teacher Li, you can also talk about it, people have eyes, is it because they have eaten the fruit of wisdom?" ”

Teacher Li: "Who knows this, and do you know that there is a tree of life in the Garden of Eden, and if you eat the fruit on it, you can live forever." ”

Zhang Jingwen: "I want to find the tree of life, that is the hope of mankind." ”

In the "Wangtian Cave", Zhang Jingwen happily turned around all day, and this boring day turned into a magical day.

When she returned to the dormitory in the evening, Zhang Jingwen was still excited, and she hoped that she could have another sweet dream, go to the Garden of Eden, steal a fruit from the tree of life, and swallow it in one gulp.

Unfortunately, legend has it that the angel cherubim was stationed on the east side of the Garden of Eden, and he used a sword that swirled in all directions and emitted flames to guard the road to the tree of life.

That's really a point of no return.

Is there really no way, after all, people still have eyes, no matter how long the road is, they must go on under the guidance of their eyes.

Alas! Unfathomable gaze.
