How many times have humans become extinct?

Humans have been extinct for four times.

Modern science has confirmed that there have been several catastrophic extinction events in the history of the earth, and every time there will be biological extinction. There are many periodic disasters on the earth, which directly prove that prehistoric human civilization is likely to be destroyed by various disasters, such as earthquakes, floods, volcanoes, comet impacts, and the rise and fall of continental plates. Some people boldly infer that there were several advanced civilizations on the earth, but they were all destroyed, and modern human civilization is only one of them.

If so, then many unexplained phenomena on earth make sense. For example, Egyptian pyramids, Easter Island statues, British stone pillars, palenque Temple spaceship reliefs, the sinking of Daxizhou, and even pottery pots with astronauts' heads unearthed at Banpo site in China.

British anthropologist Van Persie published a simulated History of Earth Civilization in 2004. This is not science fiction or fairy tales, but a chronicle of civilization based on scientific research.

Two billion years ago: the first civilization was born, using nuclear energy, and was finally destroyed by nuclear war. This can explain the phenomenon that there was a nuclear reactor in Oklo uranium mine in South Africa two billion years ago.

The photos of the real earth are too scary. Many people are very satisfied with the earth we live in, but with all kinds of pollution, our earth has become ugly. Next, I will take you to know the horrible photos of the real earth.

The photos of the real earth are too scary 1

Overseas media said that many people's impression of the earth is probably beautiful water blue, but in fact that photo is "PS". Recently, the Japanese meteorological satellite Sunflower 8 took a detailed image of the earth, which is the first photo showing the true color of the earth.

On February 24th, 65438 in Taiwan Province Province, the British Daily Mail reported that the meteorological satellite Sunflower 8 was launched on June 24th, 65438+1October 7th. Recently, an image was taken at a distance of 35790 kilometers from the Earth, showing the details of clouds, oceans and deserts. With super high resolution, this is the first original picture of the earth without any color modification.

Japanese satellites photographed the real face of the earth.

In the past, people's impressions of the water-blue earth came from this photo.

In the public's impression, the water-blue earth is actually a color-corrected photo taken by NASA, which is very different from the gray earth taken by Sunflower 8. However, this so-called "true color" photo does not refer to the image seen by the naked eye, but the real face of the earth in space.

"@ NASA Chinese" also published a photo of the earth without makeup, which surprised netizens. It is uneven, with one concave here and one convex there. Generally speaking, some netizens said it was like a sweet potato, some netizens said it was like a spare tire, and some netizens said it was like a pomegranate.

For this photo, astronomical experts said that the earth is really not an authentic sphere, and its appearance is a bit strange. The reason why the earth is so long is that it not only revolves around the sun, but also rotates. There is both land and water on the surface of the earth. In order to maintain the internal gravity balance, all parties grow into this strange shape under the "struggle".

In fact,

Now, scientific means are developed, which opens up many ways for earth survey. Through actual measurement and analysis, accurate data are finally obtained: the average equatorial radius of the earth is 6378.38 km, and the polar radius is 6356.89 km. It is also found that the Arctic is about 18.9 meters high and the Antarctic is 24 ~ 30 meters low. It seems that the earth is shaped like a pear: its equatorial part protrudes, which is its "pear body"; The North Pole is a bit sharp, like "pear pedicle"; The South Pole is a little concave, like a "pear navel", and is called "pear-shaped earth". To be exact, the earth is a triaxial ellipsoid.

We are always talking about finding extraterrestrial civilization and emigrating to other planets. We are always eager to emigrate to the stars. However, it is pessimistic that up to now, although more than 4000 exoplanets have been discovered, only the earth is still the only known planet with life suitable for human survival. In our stereotype, since man took the first panoramic photo of the earth by satellite 43 years ago, the earth has always been a vibrant blue planet with completely different oceans and continents.

43 years ago, when the first panoramic photo of Zhang Weixing was released in the world, people were shocked by the beauty of the earth, and we were proud of it. More than 70% of the oceans are covered by dense forests on land, which makes our earth like a fairyland, blue and green, colorful and well-defined. Since then, this beautiful image has been engraved in our minds, lingering. Forty-three years have passed, and our earth has not changed at all. Is it really still that beautiful?

In 43 years, the earth has changed. You may not believe it. The earth has changed in less than half a century. It has lost its beauty, even beyond recognition. Yes, the earth has become ugly now, and its appearance has been destroyed by human beings. You may not believe it, but it's true.

Due to the different social division of labor, for most people, there is actually no chance to go directly into space to see the true face of the earth, and even the original photos taken from space at first hand have no chance to see it. All we can see is the processed information and release.

Yes, the earth is beautiful, but that was in 1978, when humans photographed the earth. It's really beautiful, with a clean atmosphere and a vast blue ocean. At that time, the damage caused by human beings to the earth was really small, and there was almost no impact. At that time, the earth had enough ability to digest and deal with environmental problems caused by human beings, but now it has changed, and our destructive power has exceeded the capacity of nature.

In recent years, with the development of human society, we have indeed paid a huge price. Looking at the earth from space, the ocean is not so blue, the land is not so green, the atmosphere is not so normal, and the earth is a little grayish brown.

This is just the interior of the earth. Do you know that outer space is not pure land? In recent years, with the increasing dependence of mankind on artificial satellites, a large number of spacecraft have flown into space and successfully put into normal use, and failed or failed to become space junk. So it is conceivable that our earth has a layer of high-speed garbage. The space environment is inherently dangerous and complicated, especially with so much man-made space junk, the earth is even more dangerous. In particular, we are almost helpless about space junk, and there is no way to recycle it, so "space junk" will only increase.

There are more than 200 countries and regimes in this world, and everyone has complicated relations and interests, but we should remember that the earth is our home. Before we have the ability to create a new star, we should protect it well, because it is the foundation of all of us. We should keep the ocean blue, the sky clean and the earth evergreen. We should not give up environmental protection completely for the sake of economic development, because we must suffer in the end.

Our earth belongs to us, but it belongs to those descendants after all, so do you think we should protect it in time in the face of the deteriorating earth environment?

There is an old Indian proverb that says very well, "Only after cutting down the last tree, catching the last fish and polluting the last river will we understand that money can't be used to eat"!

Maya predicted that there would be zombies in 2023.

No, zombies belong to pseudoscience, and comics are purely eye-catching.

Because zombies don't consume energy, they will starve to death soon. According to people who can't come back from the dead, zombies may be viruses, but they definitely won't live that long, because living things only need a lot of energy to control nerves, and it's not worth it.

On zombies who lose their immune system, wounds will rot, and scavengers such as flies will also kill zombies.

Zombies walk with a limp, osteoporosis, calcium deficiency, easy to fracture and difficult to walk.

Prediction is also pseudoscience. Isn't the "doomsday" of 20 12 a Mayan "prophecy"? Why are you still alive? Don't believe it.

Zombies are non-existent creatures. Don't be scared into nightmares.

In what year did zombies appear?

According to Shan Hai Jing, the earliest zombies appeared in the period of the Yellow Emperor.

There are five sayings in later generations:

1: According to Shan Hai Jing, the earliest zombies appeared in the period of the Yellow Emperor, and were called Nu Wa, also called Hiderigami. According to legend, Nu Wa trudged thousands of miles on the bare ground: she carried the wings of a blood bat, which could fly to the ground to absorb the power of the moon for her own use; nine bone spurs between the wings could lead to nine days of mysterious fire to attack the enemy: at her feet.

The first kind: the slave girl is the daughter of the Yellow Emperor.

This statement is a folklore. It is said that the Yellow Emperor attacked Chiyou and his beloved daughter died. Huangdi absorbed the qi of heaven and earth into Yin with great divine power to revive her, and used her divine power to eliminate the hostility caused by the qi in Yin, so that Nu Wa had great fighting power and became a great help for Huangdi to fight against Chiyou.

The second kind: the female scorpion falls from the sky.

This statement is official, which means that it is recorded in most ancient history. "The goddess descended from the sky and helped the Yellow Emperor defeat Chiyou. After breaking the spell, she was unable to return to heaven."

2. The word "zombie" comes from Mainland Thousand, a Taoist book. Zombies mean: stiff limbs, not low head. Eyes are not oblique. The legs are not divided, and the body is not rotten.

Zombies prevailed after the middle of Ming and Qing Dynasties. Most people recorded zombies in Qing Dynasty, and Yuan Mei's Woods Language and Ji Xiaolan's Notes on Yuewei Caotang were the first two, which can be said to be complete works of zombies. The theory of corpse removal in western Hunan, also known as the theory of moving souls, belongs to the You Zhu family in Maoshan, and originated in Yuanling, Luxi, Chenxi and Xupu counties in western Hunan. When the body was not corrupt, it was rushed back to the township for burial by the magician. Corpsers usually travel in small groups. Some of them tied the bodies with ropes every few feet, and then put yellow paper symbols on their foreheads. Others knock gongs to clear the way and walk at night. Before dawn, the crib was thrown and the paper was lifted, and the body stood against the wall. At night, the road continues. It was pointed out that the corpse driver actually carried the corpse, but because he was dressed in black at night, passers-by naturally couldn't see the corpse driver and thought there was a corpse.

According to Hunan folklore, zombies were first used for drug trafficking. A man dressed as a Taoist is a drug dealer. As mentioned above, they walked in groups of three or five, but instead of tying the body with a rope, they put the body on the shoulders of the former and later generations with wooden sticks, so that it seemed that the body could walk. Ring the bell, yellow paper symbol, all to hide people's eyes and ears. This method is a good method for drug trafficking, because ordinary people dare not approach it, and officers and men are unlucky. Walking at night is good for preserving the body. Of course, drugs such as opium can be stored in the body, which is safer.

4. Yuewei Caotang Notes divides a corpse into two reasons: sudden change into a new corpse and long burial without decay.

Vegetarian meal in a corpse, which is more scientific? The pH of soil is extremely unbalanced, which is not suitable for the growth of organic matter, so it will not breed ants and bacteria. Even if the body is buried for a hundred years, the muscle hair will not rot. Some data show that the hair and nails of the corpse will continue to grow. There is also this sentence in Feng Shui.

The picture material of female mummies-women and women legend has it that there is a way to refine the shape of the moon. When a body is buried for hundreds of years, it will come back to life at the expiration. The corpse that just died was possessed by evil things/spirits, and the corpse absorbed the yang, which made people angry and turned into a corpse. When a person dies, the soul is scattered and stagnated.

Yuan Mei's Woods Speech: The human soul is good and evil, but the human soul is ignorant, and the soul dominates the human body. When the soul leaves the human body, it will become an evil ghost zombie.

5. In unofficial history of Qing Dynasty, there was a story about zombies. Roughly speaking, in the early Qing Dynasty, there was a small village in the west of southern Hunan. A rogue in the village was poisoned by ptomaine for robbing a tomb, but was rescued by an old man. However, he was beaten by the whole village again because of his misconduct, and then he was left to fend for himself in the grass in the back hill. A few days later, he asked for help again, but this time no one wanted to help him. The villagers beat him and tied him to a tree. Although some people spoke out to discourage it, no one paid attention. Finally, he died in a tree. In the evening, the villagers wanted to bury him, but they found the body missing. Finally he came back and killed the whole village. The villagers were bitten and turned into zombies. Some villagers who left in time turned into zombies when they visited the village in the morning.

Actually, we're all dead.

A joke many years ago:

A couple took part in a group mountaineering activity. The girl was particularly uncomfortable when she went up the mountain, so she set up a tent at the foot of the mountain to rest and told her boyfriend that it was not easy to come. Go up the hill with them and I'll have a rest. So the boy climbed the mountain with other climbers. Who knows that at night, there was lightning and thunder and it rained heavily. It was dark and the mountaineering team retreated, except for the boy. The captain told the girl regretfully that the road was slippery on rainy days and the boy slipped and fell off the cliff. When everyone found him, he was already dead. Let's rest here tonight. The girl is very sad and still can't sleep. Suddenly the tent was opened from the outside. When the girl saw it, it turned out to be a boy with long hair and muddy body! Boys grab girls' hands and drag them out! The girl was frightened and asked with trepidation, aren't you dead? Why did you come back to scare me? The boy whispered, there was a mudslide on the mountain today, and the mountaineering team was wiped out. Only I survived. Everything you saw at night! Yes! Go to hell! People! ! ! Run with me!

The joke finally asks: If you were a girl, would you go with a boy?
