The more they can't pursue Huo Yushan, the more itchy the men will be, and the more fierce they will pursue.

This is the man's desire to conquer.

At this time, they unexpectedly found that Huo Yushan and a strange man were walking side by side, talking and laughing all the way, which had never happened before.

Many young talents in Hong Kong City began to feel uncomfortable.

Envy, jealousy, hatred!

"Who is this person, and why are you so close to Miss Huo?"

"I don't know, but I don't know which kid doesn't know the height of the sky!"

"Hmph, this kid is mediocre, and I don't know how Miss Huo likes him. ”

"I think eighty percent of him is stalking!"

The young talents of Hong Kong City all spoke sour words because of jealousy.

Yang Xiaotian naturally vaguely heard such remarks, but he didn't care, but talked with Huo Yushan with great interest.

As a child of the Huo family, Huo Yushan did not become a successful businessman as arranged by his elders, but was admitted to the physics department of Oxford University with excellent grades, and later majored in astrophysics and became a physicist.

She is currently working on her own research in astrophysics and is a lecturer in physics at Hong Kong City University.

It just so happens that Yang Xiaotian is also a science and engineering man, and the two have a special common topic.

Others think they are talking about love and love.

But in fact, they had just finished discussing quantum mechanics, and their thinking was jumping, and they were talking about aliens

The main discussion is the Fermi paradox of why aliens have not been discovered.

"Have you seen Liu Cixin's "Three-Body Problem"?" Huo Yushan said to Yang Xiaotian.

"Uh...... When I was at MIT, I read it in my spare time. Yang Xiaotian pondered for a moment and replied, "It should be said that I have read all of Da Liu's science fiction novels, so I am familiar with them!"

As a standard science man, Yang Xiaotian loves to read science fiction.

Liu Cixin, Arthur C. Clarke, Verne and other works Yang Xiaotian has basically read them.

"So what do you think of the Law of the Dark Forest's interpretation of Fermi's paradox?" Huo Yushan threw a question at Yang Xiaotian.

In the novel "The Three-Body Problem", the law of the dark forest perfectly explains the Fermi paradox. Yang Xiaotian thought about it and said.

Huo Yushan said: "What do you mean?"

Yang Xiaotian said: "In the real world, I am more inclined to the big filter hypothesis. ”

The Great Filter Hypothesis. It is also an explanation of Fermi's paradox.

What is the Fermi paradox? That is, according to the science of probability, there must be a large number of intelligent life in the vast universe, and these many intelligent life forms will inevitably develop advanced civilizations, so it stands to reason that human beings should have come into contact with aliens a long time ago, and even the footprints of aliens all over the galaxy are no exception.

For example, if aliens are advanced civilizations, there will probably be Dyson spheres, which are easy to observe.

Aliens are advanced civilizations, so it is likely that there will be von Neumann probes, which are easier to observe.

However, the universe observed by humans was dead silent, and no aliens were found.

This is known as the Fermi paradox.

The Great Filter Hypothesis is that there is a large filter in the universe, and this filter is so cruel that most civilizations have not been eliminated directly.

For example, the carbohydrate reaction gives birth to cells, which is the first filter.

Most planets don't have water, so most of them are filtered out.

Another example is that single-celled life becomes multicellular, which is another filter.

The mass extinction event of various ancient organisms is also a filter.

Then the birth of intelligent life may be a crucial filter.

Whether intelligent life can develop science is a filter.

And whether science has a ceiling, and whether life will use science to destroy itself is also a filter.

Filtering is everywhere, brutal and real.

To explain the Fermi paradox with the Great Filter Hypothesis, it can be said that life was born harshly and filtered most of the planets, life evolution was harsh and filtered most of the planets, intelligent life was born harshly and filtered most of the planets, and finally only a few planets developed civilizations.

However, civilization is fragile, science is not omnipotent, a solar helium flash, a civilization is destroyed, a volcanic eruption, a civilization is destroyed, a nuclear war is destroyed, a civilization is destroyed. Therefore, most of the civilizations in the universe have been filtered out, which is why the universe seems so lonely.

"Why would you lean towards the big filter hypothesis?" Huo Yushan asked Yang Xiaotiandao.

"Because I think the real law is terrible. Yang Xiaotian said, "The most terrible thing is that science and technology have an upper limit, and they cannot be developed indefinitely. In fact, there is already such a trend, and the Saturn V of the Apollo moon landing is still the most powerful rocket of mankind. A hundred years ago, quantum mechanics and the theory of relativity were still at the forefront of science......"

The two were chatting with great interest, but they met a couple and interrupted their conversation.

Yang Xiaotian recognized that this was a very famous couple in Hong Kong City, Huo Qigang and Guo Jingjing. Huo Qigang is the grandson of the Huo family, Guo Jingjing is a famous sports star, he can marry the Huo family, and he is very affectionate with her husband, I don't know how many others are envious.

"Big brother, sister-in-law. Huo Yushan said very politely to the Huo couple.

"Mr. Huo, Ms. Guo, hello. Yang Xiaotian also greeted the two.

Hodge just looked at Yang Xiaotian curiously, and said with a smile, "Little sister, I remember that you have always been unapologetic to men, and it is really rare to have such a happy chat with this gentleman today, what are you talking about?"

"The Fermi paradox. Huo Yushan said truthfully.

Hodggang: "......"

Guo Jingjing: "????"

Seeing that his brother and sister-in-law were speechless, Huo Yushan introduced Yang Xiaotian to Huo Qigang and said: "This is my new friend Yang Xiaotian today, the chairman of the Twin Group......"

Hodge's eyes lit up.

At this moment, not far away, another eye-catching couple appeared.

Mr. and Mrs. Hui.

Xu Hengjing.

Li Jiaxin.

Li Jiaxin was once known as the first beauty in Hong Kong City.

Although he has rich emotional experience and has been a junior, he has now married into a wealthy family for many years and is pampered.

It's just that Fanghua has passed away, and there is no longer the domineering that he was when he was beautiful.

Beside Mr. and Mrs. Hui, there were two men who came with Mr. and Mrs. Xu. When one of the tall and thin men swept his gaze across the field, he suddenly found Yang Xiaotian, and his eyes immediately froze, and his expression was cautious.

"It turned out to be Yang Xiaotian, this bastard, this is really a narrow road!"

"It's a pity that now you're in the light and I'm in the dark, I seem to be able to fix you!"

In this man's heart, he had a bad idea about Yang Xiaotian.

The other man, looking at Yang Xiaotian, who was quite close to Huo Yushan, was a little angry, and his eyes were full of fire.

He's furious!
