Chapter 141 Different Perspectives, Different Views

He understood it, but the words left and right made him feel a little confused. Just when he was about to say something, he heard footsteps behind him, and at the same time, a loud voice came.

"That's just Lao Yi's analysis from a biological perspective. In my opinion, the fundamental reason why the DNA of life on this planet is left-handed is still the problem of quantum and the direction of the planet's chiral rotation."

Hearing this loud voice, Yue Yuan knew it was Liu Miyan. This guy had been in the bridge just now. He should have heard him talking to Yi Kai. He probably had his own opinions.

"It's Lao Liu, what? Do you have another explanation?" Yue Yuan asked cooperatively.

"It's just a commonplace point of view." Liu Miyan shook his head, walked to the other side of Yue Yuan, and then said in a loud voice: "You should have discovered that the rotation of this planet is from east to west, right? Our earth is Turning from west to east, it’s the exact opposite of Venus.”

"Yeah!" Yue Yuan and Yi Kai nodded. They all saw the rotation direction of Wolf 1061 c. It was indeed reversed.

The so-called orthogonal reversal here is based on the earth, and the earth rotates from west to east, that is, right-handed. In popular terms, it is called left-to-right, but right-handed rotation is not right.

So it doesn’t mean that if your head points to the northern hemisphere and your feet point to the southern hemisphere, it turns from west to east, but if you turn your body upside down, it turns to east to west. No.

Well, it’s easy to understand if it is converted from west to east into a right-hand rotation.

You turn your body upside down and see that the earth's rotation direction is still right.

This is chiral right-handedness. To put it simply, hold the earth in your right hand, with your thumb pointing towards the North Pole, and the direction of the four fingers is the direction of the earth's rotation.

If you turn your body upside down, you still have to hold it with your right hand so that the thumb and four fingers correspond to the north pole and the direction of rotation respectively, so it is called a chiral right-handed planet.

As for the Wolf 1061 c, you have to hold it with your left hand so that your thumb points to the North Pole and your four fingers rotate in the same direction.

Therefore, although the universe is not divided into southeast, northwest, and front, it is divided into left and right. Any civilization that discovers the law of nonconservation of parity in weak interactions knows this law.

When communicating with an alien, you say: "We agree that those with right-handed spin will be called the right side, and those with left-handed spin will be called the left side." Then you throw the alien a parity-nonconserving cobalt 60 experiment, so the alien The star people will naturally understand the directions to the left and right that both parties are referring to.

As human beings, Yue Yuan and Yi Kai obviously knew that the cobalt-60 experiment proved that parity was not conserved, so they did not foolishly say anything like turning the solar system over, turning the planet over, or turning the galaxy over.

At this time, Liu Miyan hit the guardrail with one hand, turned to look at Yi Kai and Yue Yuan, and continued: "From the perspective of the light quantum world, it can be explained that due to the left-handed chirality of this planet, its main sequence starlight At the moment of contact with the planet, the child must have a tendency to rotate leftward with the planet.

As a result, the earliest ancestors who absorbed energy through light were also affected by the left-handed trend in their long-term evolution. Because photosynthesis is continuous and uninterrupted in the process of life formation, photosynthesis must also affect the structure and properties of life. . "

"In other words, photons must be involved at the beginning of the formation of life. Since the chirality of this planet is left-handed, the photons that reach the planet have a left-handed tendency. Under the long-term effect of the planet's left-handedness and light, the creatures on this planet have The left-handed DNA structure."

"The movement, left-handed tendency, and entanglement of light quanta will affect the organic matter formed by photosynthesis, and then affect the structure, characteristics, and properties of organisms from small to large, thus forming a left-handed DNA biosphere.

In this process, because the spin of the planet has not changed since the formation of the planet, no matter how many evolutionary links and stages the life formed goes through, there is always the factor of "left-handed driving force" affecting it. Therefore, the main melody of life DNA on our earth is right-handed, and the main melody of this planet is left-handed DNA. "

After hearing this explanation, Yue Yuan frowned and looked at Liu Miyan, and said with some confusion: "That being said, most of the enzymes on this planet are right-handed. Since the light quantum has always had a left-handed tendency due to the direction of the planet's autotransmission, then There’s no reason why the proteins, enzymes, etc. they make up should be right-handed.”

Yue Yuan felt that if what Liu Miyan said was true, other large organic molecules should also be left-handed. After all, the 'left-handed driving force' has always been there.

"Because it's stable and solid."

It was Yi Kai who spoke. He seemed to remember for a moment, and then explained: "I wonder if the president ever played with skipping rope when he was a child, um, or maybe a wooden top. If he did, it would be easy for the president to understand.

When braiding a rope made of straw, if you twist a single strand to the right, then when intertwined with another strand, you have to twist it to the left to make it strong. "

"The same goes for the rope used by wooden tops. The rope used by right-handed people is also woven in a double right-hand direction, so that the rope becomes denser with use, because right-handed people throw the top to the left.

If a right-handed person's gyro rope is given to a left-hander, the rope will become loose after a few strokes, and will eventually fall apart if it continues to be used. "

While talking, Yi Kai probably thought of Yue Yuan's growing up years, and was afraid that he would misunderstand that he was talking about the kind of plastic spinning tops bought on the market, so he even posed in a few top-playing poses.

Then he explained that it was a kind of spinning top played by rural children, made of wood, and the rope was also woven with tree bark. During the game, one side would spin the top on the flat ground, and the other side would swing their arms and aim to hit it from two or three meters away. The one who hit the top would compare the two sides' spinning tops for longer, and the one who spun longer would win.

To be honest, after Yi Kai's description of language and gestures, Yue Yuan roughly understood what kind of spinning top it was, but he really didn't play it when he was a child.

According to Yi Kai, that kind of wooden spinning top should be something from the 1990s. As a post-00s Yi Kai actually played it, which made Yue Yuan a little curious about his childhood happiness.

Although he was not curious enough, Yue Yuan did not ask at this time.

Yi Kai's metaphor was very popular, but it was easy to understand. At least Yue Yuan no longer had the confusion just now.

Whether it was analyzed from a biological perspective or a purely physical perspective, it was scientific research. Yi Kai would not run over to explain left-handed and right-handed spinning to Yue Yuan when he had nothing to do.

Yue Yuan believed that Liu Miyan was the same.

After the analysis, they will definitely follow their own ideas and use their own methods to study this left-handed DNA biosphere. Only in this way can they really work hard.

Sure enough, the next moment, Yue Yuan saw Yi Kai rubbing his hands like a fly, and then he changed the subject and began to talk about the research project he was preparing with a smile.

After hearing this, Liu Miyan also showed his fangs for funding, resources, and talents.
