The 200 million-year revolution cycle of the sun caused 5 major extinctions of life on earth?
From electrons to stars, everything in the space and time of the universe is in endless motion, proclaiming its own existence
while the earth orbits the sun, The sun is also revolving around the center of the Milky Way galaxy in a”trailer”, revolving once every 220 million to 250 million years, so according to the”Milky Way”, the sun is actually only about 20 years old, and in the”20 years” of the sun, There have been 5 mass extinctions on the earth.
The first mass extinction occurred 450 million years ago, ending 85%of the species on Earth at that time. The scientific community temporarily believes that the gamma-ray burst of a nearby star severely damaged the ozone layer and caused this extinction event.
The second mass extinction occurred 377 million years ago, and 78%of marine life was taken away. The culprit was 300 billion cubic meters of”magma spewing out due to unknown reasons”
The third time The mass extinction occurred 251 million years ago. 98%of marine life and 96%of land life disappeared in”just 500,000 years”, as if they had never appeared before. As for the cause, the scientific community speculates that it may It is a chain of volcanic eruptions.
The fourth mass extinction occurred in the late Triassic period 200 million years ago, and the culprit is said to be”magma.”
The fifth mass extinction is familiar to all of us. The”dinosaur mass extinction” that occurred 65 million years ago was caused by an asteroid with a diameter of 10 kilometers hitting the earth, although it brought It hurt a lot, but it also laid the foundation for the subsequent outbreak of mammals, especially the emergence of humans.
Through the above review, it is not difficult to find that the previous mass extinctions are still in the”unsolved mystery series” for the scientific community today. Then is it possible that the mass extinction was caused by the sun orbiting the Milky Way galaxy? What?
The earliest life discovered in the scientific community is microorganisms 3.8 billion to 4.2 billion years ago. Therefore, the life history of the earth is generally considered to be only 3.8 billion years. In modern evolution theory, all the animals, plants and microorganisms on the earth today, including human beings, evolved from basic life 3.8 billion years ago.
but after For quite a long time, only basic microorganisms existed on the earth. It was not until the Cambrian life explosion that”unable to be perfectly explained by the theory of evolution” 540 million years ago that life on earth had”extinct qualifications”.
From the Cambrian period 540 million years ago to today, there have been 5 mass extinctions on the earth. On average, every 100 million years Occurs once
At first glance, one extinction in 100 million years seems to have nothing to do with the solar revolution cycle of 220 million years
But don’t forget, we In a moving universe
At this moment, there are 150 billion to 400 billion stars orbiting the center of the Milky Way with the sun. Although the surrounding stars of the solar system do not change much on the scale of hundreds of thousands of years, they are safe enough. , But in the 220 million-year revolution period, it’s hard not to”step on thunder” in the solar system
Black holes and jets from black holes, neutron stars and neutron stars, are dying Old stars, these”cosmic landmines” are threats to the solar system. If black hole jets and pulsed jets of neutron stars sweep the orbit of the solar system, the earth’s atmosphere will be stripped off and all life will be radiating Extinct.
And if the solar system If there are old stars about to explode in supernovae in the future orbit, the high-energy particle stream produced by supernovae within 100 light-years will completely destroy the earth’s atmosphere, smash or even tear the fragile DNA of life on earth.
According to astronomers’ current observations, Betelgeuse, 640 light-years away, and Haishan 2, 7,500 light-years away, may be thousands of in the future. If the light cone effect is taken into account, the two stars may even have or have already exploded.
Human civilization is now just heading towards a doomed end?
Although at present, except for the first mass extinction which may be related to extrasolar stars, the other four revolutions of the solar system have not yet found obvious causality. But from the perspective of the entire life history of the earth, the five mass extinctions are not all of them. There are actually a little embellishment between these five times, which is a series of”small extinctions”, their”connection” with the universe. It seems closer.
For example, the mass extinction event of marine life that occurred 2 million years ago is considered by the scientific community today to be caused by two dying stars 300 million light-years away, because the abnormal iron-60 isotope discovered by scientists on the seabed can only Generated by a stream of high-energy particles exploded by supernovae. Even the entire ice age of the Earth was also caused by a stream of particles that reached the earth 2 million years ago.
A small probability event that occurs once in a hundred years or even once in 10,000 years, placed in the universe for tens of billions of years Is very frequent in the history of and human civilization is living in the”cracks” of small probability events at this moment, no one knows what is happening in the depths of the universe or what has already happened .
