Dad's duty is to study the causes and hazards of holes, and he submits his thoughts and feelings to his superiors once a month.

And I used the forum I was on to help my dad summarize, which was also helpful.

It is worth mentioning that I have used the name of the earth's black hole in the submitted documents many times, and my father did not think that it was submitted directly.

But then it was criticized separately by the superiors, and the state did not recognize it as a black hole.

According to the superiors, you don't know what he is called a black hole on the earth.

Is there still a black hole in the universe that is not afraid of misunderstanding by ordinary people?

Later, my father would carefully replace the word "black hole on earth" with "hole" and turn it in, so I would also carefully modify this term.

In this way, my father and I also found a lot of things, such as these holes are found in the vicinity of famous buildings, such as the Statue of Liberty in the United States, directly below the Eiffel Tower in France, a room in Big Ben in England, the Great Wall of China on the North Great Wall, Moscow's Red Square in Russia, the Leaning Tower of Pisa in Italy, the Taj Mahal in India, and the Netherlands in the Netherlands, etc.

And the shape of the hole is perfectly round.

The perfect circle is a concept, as if pie is an infinite number of digits after 3.14.

A circle can only be perfectly circled unless it is programmed by a computer or drawn with the help of a tool.

But there is no such thing as a perfect circle in nature, just like a perpetual motion machine that has been realized on this black hole on Earth.

There is an analogy in the most microscopic world, everything is fluctuating, and there is no smooth arc. So how round the circle is depends on how thin you look, if you look at the sun from the earth, the sun is round, but if you run near the sun to see it, it is not.

And this black hole on the earth is almost a perfect circle everywhere it can be seen and touched.

Of course, I also tried to talk to my dad about the fact that this circle could not happen in nature and might not be a product of the earth, and my dad only explained to me some Planck scale that I didn't understand.

I'm an archaeology student, and I can't argue with my dad about what he is best at, quantum physics, or anything like that.

In fact, not to mention that Dad wants to know the secret of the black hole on Earth, the whole world wants to know.

Even two years ago, the Nobel Prize set up a new project called the Mystery of the Hole, which is to accumulate $200 for the black hole of the earth for the sake of this black hole on the earth, in order to ask the world to find the truth about the black hole of the earth.

But here in China, it is estimated that it is difficult to unravel, because there are many restrictions.

If you want to do anything about the hole, you have to apply for it, and you have to pass it.

As a result, you can't do anything, just look at what you can know.

In contrast, some of the earth's black holes in other countries are even open to the public for investigation. Whatever you want, as long as you don't fall off.

I'm a junior in college this year, and my father has been trying to know the secret of the hole for the past three years.

But many of the colleagues who came to investigate together have left because there is too little oil and water in it.

The monthly salary is only 7,000 yuan, but the price of goods in Beijing can not be solved by 7,000 yuan alone.

My dad also insisted because I was here, thinking that I would go back to Nanjing with me as soon as I graduated.

But as the hole gets bigger and bigger, let alone know the truth.

There aren't many people who even say a rough idea, and there are a lot of very dark claims on the Internet.

There are many categories of these statements, and I have sorted them out.

But I didn't show my father, and I roughly divided it into four hypotheses.
