5 biological extinctions! The solar system is in different positions in the Milky Way! Coincidence or arrangement?
The solar system orbits the Milky Way in about 250 million years, and the age of the solar system is 5 billion years. In this way, the solar system has fully circled the Milky Way for 20 times, that is, 20 years of the Milky Way. During this time, the earth has not exploded. But earthshaking changes have taken place on the earth! The position of the solar system in different galaxies.
Earth life has experienced 5 life extinctions, the first is the end of the Ordovician 440 million years ago, the second is 3.65 In the late Devonian period of 100 million years ago, the third time was the end of the Permian period 250 million years ago, the fourth was the period of the Triassic period 185 million years ago, and the fifth was the Cretaceous mass extinction 65 million years ago. It was destroyed at that time.
The sun is on the cantilever of Orion, The revolution speed and rotation angle of each celestial body are different and not fixed. The current celestial time is very safe in the solar system, but hundreds of millions of years of revolution will cause dangerous celestial bodies to continue to approach the solar system. In the picture below,
The solar system is in In the galaxy, rotating clockwise, we are in the blue track line, and this time, when the dinosaur was born, then rotate clockwise into the yellow line, then the green line, and finally to The age of Tyrannosaurus Rex, that is, the extinction of dinosaurs 65 million years ago, at this time the position of the solar system is at the other end of the galaxy, and in each quarter is almost a quarter At one point, there will be a general phenomenon of biological extinction.
Scientists point out that the Milky Way rotates around the central black hole, and the faster it rotates inward, the slower the peripheral rotation speed, different The revolution speed and angle will cause unexpected collisions. After all, the celestial body is not fixed, and the black hole has great gravity. It drags the celestial body to rotate, and finally gets closer and closer to the center. It is now slowly approaching the center area. The more galaxies the further, and the more asteroids, the more chances of harassment on Earth.
Currently human observable data also It is the study of biological fossils hundreds of millions of years ago, but the fact that the asteroid hit the earth did happen at many coincident times and coincident locations, and each time it was the end of a creature and the rebirth of another creature. As for whether it is a coincidence Now, the only thing scientists can observe is the past hundreds of millions of years, and the future of hundreds of millions of years is not yet known. Maybe every lap is reincarnation, and if it is transferred to this place next time, it might not be called human.
Scientists reckon that the current large-scale activities of human beings make the rate of species extinction 1,000 times faster than natural extinction, whether it is marine animals or terrestrial animals , And birds, due to the excessive killing of humans and endless development, the earth will face the sixth mass extinction in the next few hundred years, when 75%of the life on the surface of the earth will be destroyed, and it will take hundreds of times to rebuild Ten thousand years.
