Chapter 376

The less Huo Yushan is pursued, the more itchy the men are and the fiercer they are pursuing.

This is a man's desire to conquer.

At this time, they found Huo Yushan and a strange man walking side by side, talking and laughing all the way, which is unprecedented.

Many talented young people in Hong Kong are beginning to feel uncomfortable.

envious, jealous and hateful!

"Who is this man? Why are you so close to miss Huo? "

"I don't know, but I don't know which kid I don't know!"

"Hum, this boy is ordinary. I don't know what Miss Huo thinks of him."

"I think it's probably his obsession!"

All the young talents in Hong Kong City spoke sour words because of jealousy.

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

Huo Yushan, a child of the Huo family, did not become a successful businessman as arranged by his elders. Instead, he was admitted to the Physics Department of Oxford University with excellent grades. Later, he majored in Astrophysics and became a physicist.

She is now engaged in her own research on Astrophysics and a lecturer in physics at Hong Kong City University.

It's just that Yang Xiaotian is also a man of science and technology. They have a special topic in common.

Others think they are talking about romance and love.

But in fact, they have just finished the discussion of quantum mechanics, thinking big jump, talking about aliens

The main discussion is the Fermi paradox of why aliens are not found.

"Have you seen Liu Cixin's three bodies?" Huo Yushan to Yang Xiaotian.

"Er... I had nothing to do when I was at MIT before." Yang Xiaotian pondered for a moment and replied, "I should say that I have read all the sci-fi novels of Da Liu. I am familiar with them."

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

The works of Liu Cixin, Arthur Clark, Verne and others, and Yang Xiaotian have basically read them.

"So what do you think of the explanation of Fermi's paradox by the dark forest law?" Huo Yushan throws a question to Yang Xiaotian.

"In three bodies, the dark forest rule perfectly explains Fermi's paradox." Yang Xiaotian thought about it and said.

Huo Yushan said, "what do you mean by that?"

Yang Xiaotian said: "in the real world, I prefer the big filter hypothesis."

The big filter hypothesis. It is also an explanation of Fermi's paradox.

What is Fermi's paradox? According to probability theory, there must be many intelligent lives in the vast universe, and these intelligent lives will inevitably develop into advanced civilization. It is reasonable to say that human beings should have been exposed to aliens for a long time, and even the footprints of aliens all over the galaxy are no exception.

For example, if aliens are advanced civilizations, they will probably have Dyson sphere, which is easy to observe.

Aliens are advanced civilizations, so it is very likely that they have von Neumann detectors, which are easier to observe.

However, the universe observed by human beings is still, and no aliens have been found.

This is the famous Fermi paradox.

The big filter hypothesis is that there is a big filter in the universe, which is so cruel that most civilizations have not been eliminated directly.

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

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

Another example is the transformation of single cell life into multi cell life, which is another filtration.

Mass extinctions of various ancient creatures are also filters.

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

Whether intelligent life can develop science is a filter.

Whether science has a ceiling or not, and whether life will destroy itself with science, is also a filter.

Filtering is everywhere, cruel and real.

Using the big filter hypothesis to explain Fermi's paradox, we can say that the birth of life is harsh, filtering most of the planets, the evolution of life is harsh, filtering most of the planets, the birth of intelligent life is harsh, filtering most of the planets, and finally only a few planets develop civilization.

However, civilization is very fragile. Science is not everything. A solar flash, a civilization destruction, a volcanic eruption, a civilization destruction, a nuclear war, a civilization destruction. Therefore, the vast majority of civilization in the universe has been filtered out, so the universe seems so lonely.

"Why are you inclined to the big filter hypothesis?" Huo Yushan asked Yang Xiaotian.

"Because I think the real law is terrible." Yang Xiaotian said, "the most terrible thing is that there is an upper limit to the development of science and technology. In fact, there has been such a trend. Saturn V, the Apollo moon landing vehicle, is still the most powerful rocket for human beings. One hundred years ago, quantum mechanics and relativity are still at the forefront of science. "

They were chatting happily when they met a couple and interrupted their conversation.

Yang Xiaotian recognized that this is a famous couple in Hong Kong City, Hodge gang and Guo Jingjing. Hodgson is the first grandson of the Huo family, and Guo Jingjing is a famous sports star. He married to the Huo family and loved his husband very much. I don't know how many people I envy.

"Big brother, big sister." Huo Yushan is very polite to the Huo couple.

"Hello, Mr. Huo and Ms. Guo." Yang Xiaotian also said hello to them.

Hodge just looked at Yang Xiaotian curiously and said with a smile“ Younger sister, I remember that you have always been true to men. It's really rare that you chatted so happily with this gentleman today. What are you talking about? "

"Fermi paradox." Huo Yushan said it like it was.

Hodge just: "it's..."

Guo Jingjing

Seeing that his brother and sister-in-law were speechless, Huo Yushan introduced Yang Xiaotian to Hodge and said, "this is my new friend today, Yang Xiaotian, chairman of Gemini group..."

Hodge's eyes just brightened.

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

Mr. and Mrs. Xu.

Xu Hengjing.

Li Jiaxin.

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

Although he has rich emotional experience and worked as a junior, he has been married to a rich family for many years.

It's just that Fanghua is gone, and there's no more bullying like that.

Next to the couple, two men came with them. When one of the tall and thin men's eyes swept across the field, he suddenly found Yang Xiaotian. Suddenly, his eyes were fixed and his expression was cautious.

"It turned out to be Yang Xiaotian, an asshole. It's really a narrow road to go!"

"It's a pity that now you're in the light and I'm in the dark. It seems that I can take care of you!"

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

And another man, looking at Yang Xiaotian, who is quite close to Huo Yushan, is a little angry and angry.

He's angry!
