Before that, the global temperature was getting warmer. So why is this period called the new fairy wood period? Scientists have studied Greenland glaciers, and they found that the pollen of a plant that should have grown in the cold zone of northern Europe at that time began to appear in a large area during this period, and it can also be found in low latitudes. This plant belongs to Andromeda strain, which means that the temperature was very cold at that time, and this plant invaded the south like an explosion, so scientists named this period the New Andromeda Period.
During this period, the temperature in Greenland in North America plummeted by about 20 degrees Celsius, which also caused the extinction of most of the giant fauna in North America, and also led to the rapid demise of the Clovis culture of the Mayans at that time. In Europe, the temperature in southern England has also dropped by more than 8 degrees Celsius.
At first, people thought that this strange phenomenon of the new fairy wood period only occurred in North America and Europe, but with the deepening of research, we also found evidence of temperature drop in other parts of the world during this period, such as biogenic silicon deposition in the South China Sea of China and oxygen isotope 18 of glaciers on the Qinghai-Tibet Plateau, which were recorded truthfully, and there was an abnormal cooling phenomenon during that period. This shows that this is actually a great ice age all over the world.
So what happened 13000 years ago?
First, it is scientifically speculated that comets hit the earth.
There are different opinions about what happened before 13000 years ago, but the scientific community tends to think that a comet or an asteroid with a diameter of more than four kilometers hit the earth at that time, and the debris formed by the impact hit North America, South America, Europe and West Asia, which led to great floods and dramatic changes in the climate. Then it led to the great ice age of 1000 years. And this event is also known as the new fairy wood event.
In 1694, the famous astronomer edmund halley calculated the orbit of Halley's comet. He predicted that Comet Halley would return to Earth every 75 to 76 years. As for the Great Ice Age, he also thinks that it should be a comet that we humans have not yet understood, which caused a historic flood.
Another astronomer and Frenchman, Laplace, agrees. He published his masterpiece "Cosmic System Theory" in 1796. It is mentioned in the book that many people and animals all over the world have died from floods and strong earthquakes, and all species and all human remains have been destroyed, which is exactly what a comet impact can cause.
Later, more scientists put forward similar hypotheses. At the meeting of American Geophysical Union held in Acapulco in 2007, Richard firestone and West, together with about 20 other scientists, formally put forward the hypothesis that comets hit the earth for the first time.
Later, this expert group also published relevant papers in the Proceedings of the National Academy of Sciences. A few years later, more evidence seems to support this hypothesis. In 20 13, a scientific research report pointed out that the ice core in Greenland was formed about 12900 years ago. The platinum concentration in the ice core is abnormal, which is several hundred times higher than the normal state.
Scientists believe that this anomaly should also be formed by meteorite impact. It is speculated that this meteorite should be a large iron ore with a diameter of about 800 meters. In 20 17 years, the researchers detected abnormal platinum concentrations at other 1 1 locations on the road, and the historical period of these locations can also be traced back to the new fairy wood period.
By the end of 20 19, researchers have detected platinum concentration anomalies in 28 locations around the world at the same time, and they are widely distributed. This shows that if a comet really hit the earth that year, then the disaster caused at that time may be global. However, these are all scientific inferences.
Second, the age mystery of the Sphinx.
This phenomenon of prehistoric floods and climate anomalies has always been a hot topic in archaeology and geology, the most striking of which is the topic related to the Egyptian Sphinx. What does it matter?
The Sphinx near the pyramid of Kafra is one of the most famous statues in the world, but who built it and when this huge statue was built are still unsolved. Of all the ancient Egyptian inscriptions found so far. I don't know the text about this statue, who built it, how it was built, what it was used for, and so on. It's nothing.
Even his name Sphinx was given by the ancient Greeks 2000 years ago. This is because this statue, like the Sphinx in ancient Greek legend, has the body of a lion. Although everyone thinks that this statue must have stood next to the pyramid of Kafra, it is natural that it should have been built around 2500 BC. However, in 1857, Mariel, the founder of Cairo Museum, suddenly found a monument, which was probably built by the 26th Egyptian dynasty, that is, around 500 BC.
However, this inscription tells a new story. The inscription says that old Cabra found the Sphinx, which was buried in the yellow sand. Therefore, the Sphinx should actually be older than the pyramid of Kafra, but how old is it?
On the body of the Sphinx, there are some obvious wavy concave lines. Geologists have always believed that such traces should be caused by sand erosion, but this also brings another problem, that is, there are traces on the statue, but these concave lines do not exist in the face of the statue.
In A.D. 1950, an Egyptian scholar put forward a view that these concave lines should be traces of flood erosion. At that time, the flood only swallowed the body part of the statue, and the face was not submerged, so it was not corroded. This statement was later recognized by another geologist.
In the1990s, Robert Shoch, a geologist at Boston University in the United States, suggested that the time of this great flood should be at the end of the last ice age, which is almost the New Fairy Wood Age we just introduced. In 2008, two Ukrainian geologists, one named Ma Cheney Fu and the other named Pahominko, supported Xiuqi's point of view and deeply demonstrated the origin of the concave lines on the Sphinx.
From a geological point of view, they demonstrated their views in detail. For example, concave lines are caused by wave energy rather than wind erosion. They think that those concave lines are very consistent with the wavy concave lines on the Black Sea coast and cliffs, while the shape of rocks eroded by wind erosion nearby is obviously different from the traces on the Sphinx. Therefore, two scientists believe that the Sphinx has been submerged for a long time, which is true.
This undulating landscape is really mysterious, and it's not just in Egypt. In distant North America, geologist Harunbrett also found this wavy landform on the Columbia Plateau at an altitude of about 1500m. He believes that these may be caused by devastating floods, but the1500m plateau was flooded because the water source could not be explained and the extent of the floods could not be known.
So the academic circles at that time did not recognize his statement. However, Bret was not discouraged. He spent 30 years before and after and published 30 papers. Finally, he argued with more than 30 skeptics and won. Later, in 1974, the appearance of satellite images gave us a more comprehensive understanding of the earth's landforms, which was finally confirmed by the flood.
Five years later, Brett, 67, accepted the Penrose Medal awarded by the American Geological Society, which is the highest honor of the American Geological Society. In his acceptance speech, he said that although the theory of the great flood has been controversial for a long time, the photos taken by an earth satellite 900 kilometers above his head have provided clear evidence for the scope and nature of this prehistoric disaster. Anyway, if the Sphinx was really flooded more than 10 thousand years ago, it would bring another more important problem, because in everyone's impression, human beings were still in the Stone Age. Humans use stone tools, wrapped in two skins, to chase wild animals everywhere. How can they have the tools and ability to build such a huge sphinx? You know, it's more than 70 meters long and 19 meters wide, and it's a giant with six or seven floors.
Three. Gobekli Stonehenge
Some people say that all this is not impossible as long as the existence of prehistoric civilization is recognized. We are now a high-tech modern civilization, which will develop in the next 200 years. According to what everyone says at present, how could it be that several decent advanced civilizations have not developed in the long history of 4.6 billion years? Speaking of which, let's take a look at another relic of prehistoric civilization, Stonehenge in Gobekli, Turkey.
This stone array is located in eastern Turkey, about ten kilometers outside Urfa. 1994 A Kurdish shepherd found Shizhen. 1995, German archaeologist Chris Schmidt presided over an excavation. They identified that this stone array has a history of at least 12000 years and is one of the earliest cultural relics discovered by human beings on the earth so far.
In addition, Schmidt's archaeological team has so far excavated 45 rectangular or T-shaped boulders, which are five to ten feet apart to form a circle. On these stones, the main carvings are wild boar, ducks, long-tongued crayfish and lions in the hunting era. One of the huge stones is carved with a group of mysterious images, including vultures, wolves, scorpions and snakes. However, since it was excavated, until recently, no scholar could decipher the meaning of these pictures.
On June 28th, 20021year, the team of archaeologist Martin Videman from the University of Edinburgh in England achieved a research result. They think that the Gobekli Stonehenge is actually an ancient star-watching platform. At this moment, different creatures actually represent different constellations, including Sagittarius, Libra, Scorpio, Ophiuchus, Wolf, Pisces, Gemini and Virgo. Because of precession, constellations appear in different positions in the sky at different times, and their relative positions on the stone can correspond to the starry sky in 10950 BC, that is, about 13000 years ago, other symbols on the stone carving, including a headless man and something similar to a shock wave in the sky, seem to describe a disastrous event.
According to Dr. sweetman, this should describe the phenomenon that comets hit the earth. He said that this cosmic catastrophe was commemorated on the huge stone pillars of Stonehenge in Gobekli. Well, here comes the problem again. 13000 years ago, Turks who liked to look at the sky at night and could clearly divide the constellations, how developed their civilization was? How did they escape this disaster?
Well, that's all for today. Do you think, in fact, for the vast universe, our human civilization is like a grass on the earth, which comes and goes with the seasons? The grass that grows in winter and comes in spring may not know what glory it once had in this land, but history will never disappear because it is forgotten.
