"Astronomers have been wondering why 70% of our earth's surface is covered with oceans. There was no credible claim to this question until man landed on the moon. One side of the moon is always facing away from the Earth, so astronomers never saw what the back side looked like until the first artificial satellite that could orbit the moon was launched.

It doesn't matter if you look at it, the dense craters on the far side of the moon are really shocking. Because the moon was bombed like this, the earth, which is much bigger than the moon, will certainly not be spared. With this kind of intensive bombing, how can the creatures of the earth survive? Hehe, do you think this is a great catastrophe for the earth?

The first reaction of scientists was the same, but soon scientists came forward and said that this terrible meteorite bombing period was an opportunity for the development of life on our earth. Why? It turns out that hundreds of millions of years ago during this bombing period, there was a planet the size of Mars that collided with the earth, turning the entire surface of the earth into a state of high temperature where even the rocks melted.

That is, there should have been almost no drop of water on our planet. Seeing the dense craters on the moon, astronomers finally understood that the reason why our earth had an ocean was because of this meteorite bombing, which not only brought countless meteorites, but also brought countless comets and asteroids made of ice to the earth.

This water is so hot that after the formation of the ocean, it covers 100% of the entire surface of the earth, because at that time the earth's crust was constantly hit by meteorites, comets, and large ice balls, and it was fragmented and very uniform, so there was no land bulge.

Scientists measured samples of lunar soil, especially craters, from the moon and found that the samples in these craters were all products of 3.8 billion years ago. When a meteorite collides, a large area of the vicinity must have melted away from the heat, and only after it slowly solidified did the rock form, at which point the radioactive elements in the rock and its decay products were sealed in the rock, allowing scientists to determine the age of the rock.

This is consistent with the geological evidence found on the earth, and there is no stable strata on the earth that were 3.8 billion years old, which can be seen to have been shattered by the meteorite bombing period.

The age of the Earth was 4.6 billion years ago, and the impact of a planet the size of Mars was about 4.5 billion years ago, and all the time period of 3.8 billion years ago is geologically called the 'Plutozoic'. The Plutozoic was later known as the 'Archean', and at this time the earth had a stable crust and vast oceans, which provided the basic conditions for the birth of primitive life.

At that time, the ocean was piping hot, and there were a lot of active iron ions. That's when the biochemical reaction to the energy of this creature on my clothes comes in. This reaction is called 'glycolysis'. Primitive life can store energy in the body in the form of glucose, which is digested when needed.

However, this is an advanced version of glycolysis on my clothes, and each step requires a special protease to catalyze, primitive life did not have such good conditions, and iron ions acted as catalysts. So, life is always changing, and every moment has its own unique environment and way of survival. ”

The two schoolchildren and their mother were completely confused.

"Is there anything you don't understand?" Teacher Wang felt embarrassed and asked a question to ease the atmosphere.

Little Sister Mercy said, "Meteorites bomb the earth...... Produced the ocean...... The ocean provides a living environment for life, and glycolysis ...... has emerged"

The poor little sister couldn't figure out the complicated logic and couldn't even ask questions, even though she had tried.

Teacher Wang hurriedly remedied: "Glycolysis is a way of energy storage, and all kinds of activities of life need energy, and only when glycolysis occurs, life is possible." If life is compared to a car, glucose is the fuel, and glycolysis is how the internal combustion engine works. ”

He felt a hint of danger, whether his job would be lost, as if he was talking too evilly, and repelled the enthusiasm of his little sisters to learn science.

In the subsequent contact, although Tracy said that Ms. Wang was "very good", he clearly felt that her "serious consideration" contained perfunctory ingredients. Fortunately, this Cheng Dù's blow had no effect on himself, anyway, today was an unlucky day, and his rouge Yanma was forcibly confiscated by the creditor, and he suffered heavy losses.

Broken Sleep, Broken Sleep! Go back and fall asleep! I'm too lazy to deal with these elementary school students, no matter how cute it is, it's not interesting.

I slept well and woke up, and found that it was midnight, well, there was about to be a long night.

While he was thinking about how to pass the long night, another creditor came to the door. However, this creditor did not come to collect debts, but to ask his brother for a drink. As soon as he met, he threw himself into Wang Zhan's arms and pretended to cry: "Dude, buddy, I don't want to live anymore, at my age, I was actually deceived by a little girl, it's too ...... It's a shame! ”

Wang Bang patted his buddy on the back and comforted: "Don't worry, don't worry, there must be a road boat to the bridge before the car reaches the mountain." What little girl? Peugeot? Big breasts? Is the butt warped? ”

Creditor: "It's okay...... But it's a liar, I met on the Internet, and I was blackmailed for 500 yuan, and I'm so angry! ”

Wang Zhan: "Only 500? Did you get a little oil? ”

Creditor: "Rub a fart oil, take me directly to a black store to consume, and order two broken drinks, for 800!" I didn't see it well, so I excused myself to go to the toilet, and I jumped into the groove with a snort, almost losing my wife and soldiers. ”

Wang Fang: "Oh, it's very witty, and the speed and decisiveness of the stop loss are impressive. It's a pity that I'm not an old cannon, buddy, otherwise I would have taken the guy to help you smash the store. Now I have to ask you for a drink! But you can only go to the roadside stalls, do you go or not? ”

Creditor: "Okay. It's been a long time since I've eaten a roadside stall, so let's be nostalgic. ”

Wang Fang: "You wait a while, I'll get some cash, these days, I usually don't bring much cash, I use Alipay and WeChat." ”

Creditor: "I can't get a few bucks, hurry up." ”

This is really a model creditor, knowing that Wang Fang's economy is not well-off, and he has never meant to collect debts when he is in constant contact.

Wang Bang is his safe haven, he suffers a loss in doing business outside, and he has an awkward quarrel with his wife, so he comes to this buddy who is more sad than himself to find self-esteem, and at the end of every party, he will remind him: "Dude remember that you still owe me a sum, hurry up and find a serious job to take advantage of the money!" "But you won't say it until you say goodbye.

Point on point, full on full.

Wang Fang lit a cigarette for his brother, but he didn't light it himself, and he officially quit smoking since Ni Cai died.

The creditor was absent-minded, and he didn't care whether Wang Fang smoked or not.

This time, in addition to complaining that the world is not good and the people's hearts are not ancient, he immediately began to talk about his wife again, and the discord with his mother-in-law's mother-in-law's family, trivial things are very troublesome, Lao Wang has to listen, who calls people creditors?

Lao Wang didn't drink much himself, but filled his brother with it, and said: "According to my own thoughts, this society will sooner or later enter the era of parthenogenesis, and I have never seen a happy day of marriage." ”

Creditor: "It's still the king, you are happy!" I am an old bachelor, although I went to the door next door, taught my daughter-in-law to play magic, and became a living person in the nest, haha! ”

Lao Wang: "Fuck your uncle!" How can I do this? This is your ideal life, right? ”

Creditor: "Alas, I really have no choice, I was forced by my family, otherwise I would have wanted to live like you." It's so time-consuming to have a son, don't look at me showing the baby in the circle of friends every day, the baby is bitter, the baby just doesn't want to say, woo woo! ”

Lao Wang: "I am also bitter in my heart." Sometimes when I wake up and find that my surroundings are empty, I immediately fall into a state of loss, and I feel empty in my heart. The cohabitation instinct, which has evolved over millions of years, is not something that our generation can adapt to. ”

Creditor: "You just spend it like this, and you're not going to leave offspring?" ”

Lao Wang: "Didn't I tell you?" I don't want to settle for anything. It doesn't matter if you don't have offspring. My genetic theory has already told you that only 250 genes belong to humans, and people and bananas have 50% of the genes in common. Biological offspring are actually very different in this age of knowledge. Old Lord Newton, who was also the president of the Royal Academy and the director of the Mint, had no interest in leaving biological offspring, and he did not prevent the knowledge from being passed on from generation to generation.

Darwin was generalized lactose intolerant, but he didn't know about his disease at the time, so he felt that he was genetically bad, and he once seriously considered not getting married. He also carefully wrote down the pros and cons of getting married and not getting married for his own reference, haha.

By the way, there's a story to tell you. Or old lord Newton. Before he became famous, the astronomer Halley approached him and asked him to calculate the orbits of the planets in order to determine what was drawing them in circles. How do you know that Newton has already calculated the law of gravitation, and said, wait, I already have the results of the calculation, but I haven't found my own small piece of paper in the room for a long time.

Haha, the paper that changed the law of gravitation in the whole world was actually thrown away casually by Lord Niu. Do you know how I feel when I see this? This is really the best forced force in history! It also shows that being obsessed with science is good enough in itself, and you don't need anything else to enrich your life.

Billionaires and tens of thousands of people admired like Steve Jobs are not sometimes confused, and they think that alternative medical technology is a good thing. Dead, right? There will be a man who spends his money, plays with his woman, and beats his baby. The helper is not as rational as me, and every time I think of this, I feel a sense of intellectual satisfaction when I think of the 1% of people who are scientifically literate. It doesn't matter if you take advantage of the money or anything. ”

Creditor: "...... Are you satisfied? What about the money owed to me? ”

Wang was stunned: "You...... Why don't you act according to the script? Isn't it meant to be mentioned at the end of the breakup? ”

The creditor squirted a sip of beer: "Haha! Fun for you! Look at your nervousness! ”
