Next to the M3 cluster, a point of light larger than the cluster appears in the observation screen, and in addition to the visual deviation of the distance, this thing can also be described as a "giant comet", and it is coming towards the Earth.
According to astronomers and scientists observing the universe, this mysterious giant comet will reach a "visible" distance on the 12th. Given that meteor showers can also be visible to the naked eye, but we miss it every time and can't really accurately capture the results with the naked eye due to weather and light pollution, I think it doesn't matter if you can see it in the future in a few days, the important thing is that it is too big and "really happening"!
The astronomers of the comet, named "Bernardinelli-Bernstein" (BB), also described it in the paper as "nearly spherical cow of comets" to describe its enormity.
The discovery is the largest estimate of the comet's size in decades. The size of the comet "Bernardinelli-Bernstein" can even be compared to some of the "famous comets" in history, including a very bright comet that flew into the inner solar system in 1729.
Perhaps the most disturbing fact is that it is approaching Earth at a speed of more than 200,000 kilometers per hour, and is expected to reach the closest point to Earth on December 12, 2021, and pass through perihelion on January 3, 2022, and its brightness is also increasing.
This level of comet hitting the earth, not called a disaster, but will make us "painless" in the universe into dust, if only skimming near-Earth space, will also crash all the way to the satellite, but only the satellite is so simple?
The generation of tides is only a small matter, I think if this meteorite also has a "strong" gravitational or magnetic force, then it will cause a more life-than-death disaster to the earth, the atmosphere will be destroyed, the air will be sucked away, the earth's magnetic field will be destroyed, so that although the earth is saved, you will find that the plane in the sky will crash, and the birds in the sky will crash because they lose the magnetic field. That is a picture even more terrible than a painless destruction.
At present, since the scientific community has not issued a warning, indicating that this possibility is not very likely, the possibility of such a catastrophe can only become a kind of doomsday stunt.
For reasons of gravity, the larger the comet, the more gravitational effects in the solar system will point to a more massive star like the Sun, rather than earth. Even if it is saturn's turn, it will not be the turn of the earth to be the "guardian"!
But if the comet really avoids all the "traffic lights" and goes straight to Earth, then there may be a possibility, I think, that may solve the "nuclear weapons crisis" on Earth.
You might think of it this way, and the best and only solution to a meteorite hitting Earth disaster is to use a nuclear bomb to blow up its course or crush it completely before the comet hits Earth.
But based on scientists' descriptions of the comet, I believe that the force of just a small number of nuclear bombs on it may not have derailed it from the course of crashing into Earth.
Then it may be necessary for the world to launch all thermonuclear weapons to prevent its impact, and then it will empty the "nuclear depot" of human beings on Earth.
Then, the meteorite crisis disappeared, humanity became more united and harmonious, and nuclear weapons would disappear on Earth. The crisis of the last days is directly transformed into a new and beautiful world of peace.
However, as soon as I finished thinking about this idea, I was immediately overturned by myself, I did not take into account the ultimate weapon of mankind, that is, 'human nature', contrary to this speculative picture, human beings may feel that stockpiling nuclear weapons to intercept meteorites at any time is a necessary measure, but may build a large number of nuclear bombs... Just in case all of humanity needs, then, the next meteorite did not come, triggering the earth and winter.
Therefore, the most fundamental substantive question is that I need to work harder, and I want to find out whether there is a probability that this meteorite will pose a huge threat to the earth!
(The Global Scientific Community conducted a 1-hour query for the comet's data...) ）
I came to the conclusion that everyone should eat and drink, and that there have been no many incidents of comets of all sizes passing over the earth so far in human civilization, and there have been no disasters.
As for why the dinosaurs encountered the unique catastrophe of meteorites hitting the earth, we do not have perfect evidence and process data, so we cannot discuss it in depth.
Finally, on the 12th, how do you witness the meteorite passing by?
First of all, you must choose to observe at night, which makes it easier to catch the light with the naked eye, and also find a place or high place with low light pollution. If you have the ability, you can also take an astronomical telescope, according to the relevant information I give you a judgment is that the 12th belongs to the closest distance to the Earth observation, and then until it flies far enough to the distance that cannot be observed, there is a total of 3 days before it is observed.
So as long as the conditions permit, I am not afraid of not seeing.
As long as the comet's flight path is not in the direction of the north and south poles of the earth, most ordinary people can have the opportunity to see with the naked eye, and at that time, it will be a spectacle.
