Create nuclear fusion at the start

‘Click-click’

Countless flashes flickered wildly.

All the reporters went crazy and went up.

And the countless experts and professors in the auditorium have all turned into elementary school students at this time. Wherever Li Hao passed, everyone lowered their heads and shouted respectfully: “Expert Li! Professor Li!”

Even…… It’s Mr. Li.

Niu Li and Nakamoto trembled excitedly, one of them was a mathematician, the other was an expert in ancient language research, and it was logically impossible for their fields to intersect with Li Hao. But now, they have met Li Hao, and Li Hao is also here for them.

Whether it’s denying them, or affirming them. This proves the value and significance of their existence.

Li Hao walked past the two and nodded slightly.

Niu Li hurriedly shouted: “Li Li Li Li expert.” ”

Nakamoto bowed ninety degrees at this time: “Expert Li!”

Li Hao turned his head again and took a deep look at the stick country expert, and at this time, a look of panic flashed in the eyes of the stick country expert, and he quickly nodded and said hello: “Expert Li.” ”

‘Click’ countless flashes of light flickered.

Li Hao, under the focus of thousands of flashing lights and eyes, walked onto the podium, stroked the microphone and asked loudly:

“Who knows how big our universe is?”

The words fell, and the scene fell completely silent.

Everyone looked at each other, speechless. It’s not that I don’t know how to answer this question, but I wonder why Li Hao asked this question.

Everyone didn’t expect Li Hao’s first question to be like this…

A moment later, an English professor stood up: “According to Newton’s exposition, our universe should be a circle. It’s been born…”

Li Hao waved his hand to interrupt 023’s speech: “I just want to ask one question, who knows how big our universe is?”

The crowd was dumbfounded.

Then the England expert said: “Infinitely large.” We can’t know how big it is until we reach the edge of the universe, and we can’t figure out how big it really is. Nor can we know whether it has no end or an end. ”

Li Hao asked again: “How many planets are there in our solar system?”

Everyone shouted in unison: “Nine planets!”

Li Hao nodded: “Then in the Milky Way, how many solar systems are there?”

The crowd was dumbfounded. Many professors who had not studied astronomy fell silent. It’s not expertise they have access to.

At this time, an expert in astronomy stood up and said in a deep voice:

“In the Milky Way, there are probably more than 200 billion stars that resemble the sun. There are at least 10 billion of them, making up the complete solar system. So, there are more than 200 billion stars in the Milky Way, and there are 10 billion solar systems…”

Hiss –

Some experts who have not been exposed to astronomy knowledge gasped.

This is the first time they know this data so accurately!

This is an exaggeration, a horror!

Just thinking about it, it makes people’s scalp tingle…

I didn’t expect that it was just one galaxy, and there were 10 billion solar systems in it. What a cardinal figure is this? What is humanity in the face of the entire vast universe? Humanity is not even dust… No, even the entire solar system is just a speck of dust in the Milky Way, right?

Real dust.

It’s like a big pile of sand on a construction site.

You point to the pile of sand and ask, “How many grains of sand are there?”

If the Milky Way is compared to the pile of sand, then the sun can only be counted as one grain of sand.

And the earth is not even a grain of sand…

This is the concept of the Milky Way.

Li Hao glanced at the professor and asked, “So, how far can humans observe now?”

The professor replied again:

“The farthest distance that humans have observed in the universe is 20 billion light-years…”

Li Hao then asked: “Is 20 billion light years the end of the universe?”

The professor said in a deep voice, “I haven’t seen it.”

Li Hao asked again: “How many are in the range of 20 billion light years…”

“Uh…”

The professor was silent for a long, long time, and said in a deep voice in front of everyone, “Uncountable. It’s impossible to estimate… Within 20 billion light-years, galaxies like the Milky Way may exceed… Trillion. ”

‘Buzz+-‘ The scene was in an uproar.

Everyone was dumbfounded. For the first time, they learned about the real, vastness of the universe!

I used to just hear that the universe is vast.

But I didn’t think at all about how vast the universe really is, and I didn’t have a specific concept.

But now I know, now I understand.

This is the immensity of the universe.

There are nine planets in a solar system, and Earth is only the smallest of the nine planets.

In the Milky Way, there are more than 10 billion solar systems of this size, or even larger.

And within the current observable range of mankind, there are more than a trillion galaxies…

How small is the Earth, how small is the solar system, how small is the Milky Way?

How small.

And after knowing such intuitive data, a flash of horror flashed in the eyes of everyone present, which was a deep horror. It’s like a deep-sea phobia. Everyone will have such thoughts, after the first time they perceive their own insignificance…

And everyone gradually understood what Li Hao meant by what he was going to say.

Immediately afterwards, Li Hao slapped the table and said in a deep voice:

“I’m going to have another interaction and ask questions now. Those who do not believe in the existence of extraterrestrial civilizations in this universe… Raise your hand, please. ”

Everyone present looked at each other, and all the experts and professors who had been old-fashioned in various fields before were all dumbfounded at this time.

No one raised their hand.

If you raise your hand at this time, it is really insulting the IQ of others, and it is also insulting your own IQ (afei).

Empty.

Everyone looked at each other, and no one raised their hands.

Li Hao said in a deep voice:

“If you compare the universe to an ocean. And the entire galaxy is actually just a drop of water in this ocean. You remember what I said, I didn’t say that the earth is a drop of water in the universe. I’m talking about the Milky Way, which has 10 billion solar systems, and in this universe is just a drop of water… And the solar system is the countless molecules in this drop of water. The earth, in this drop of water, can only be counted as an atom, or even a quark. ”

“Then there is one thing in question, we have no doubt. From a probabilistic point of view. There are at least a trillion galaxies in the universe just as we can observe. From a probabilistic point of view… In this universe, there must be aliens. ”

The crowd was silent.

No one refuted it, and everyone acquiesced.

And a professor in England stood up and yelled excitedly: “From a probability point of view.” Even though, the possibility of an extraterrestrial civilization exists, it is only one in a billion. Then it must exist! Just in the 10 billion solar systems of the Milky Way, there are more than 100 million planets like Earth. Such a large base, such a large probability…”

Li Hao nodded, and asked again:

“I believe that there are extraterrestrial civilizations in this universe, and that they have developed extraterrestrial civilizations that are even more powerful than human beings. Raise your hand, please. 、”

There was silence for a while. Everyone, all hands up.

Undoubtedly!

This time, after hearing the intuitive data, no one hesitated. In the universe, there must be an alien civilization that is more powerful than humans.

Li Hao smiled, suddenly said in a solemn tone, and asked rhetorically:

“Then one of the questions we should think about is if there are extraterrestrial civilizations that are more powerful than humans. Why…… We don’t see it, but as we all know, if it develops to a certain extent in the universe, then it will inevitably go out of the planet and develop in the universe. However, humans have never observed it. Why?”

Hiss –

Everyone present gasped.

I couldn’t help but fall into deep thought.

Some people who love to drill the horns of the bull are even drenched in cold sweat at this time, and the whole person has fallen into a dead end.

That’s right, there is such a high probability in the universe that there are alien civilizations that are more powerful than humans. As long as he is stronger than a human, then it is bound to be observed. Definitely.

Even with the current level of human civilization, there are countless space junk, space stations, and spaceships outside the earth. Even if it is two light-years away, a civilization that is also at the same level as the earth, across a distance of two light-years, can observe that there is a civilization on the earth of human beings…

Then, if a more powerful civilization emerges in the universe, the earth will be absolutely 100% observable.

That’s where the problem comes in.

Why can’t it be observed?

This is the famous Fermi paradox on the earth in Li Hao’s previous life!

After the world was spoken, everyone was stupid.

Why?

Why is that?

Niu Li fell into deep thought, and muttered to himself in a cold sweat:

“It’s… It doesn’t make sense. ”

“yes, no one has ever thought about such a question. Why? Why, exactly?”

“It stands to reason that the universe is so big, there must be extraterrestrial civilizations. If there is a civilization, it will inevitably be observed by the earth, so why can’t it be observed?”

“……”

The expert of the stick country had already collapsed at this time, and he felt that his brain was about to explode, buzzing:

“Impossible…”

‘Is there actually no other civilization in the universe?’ Impossible, how can there be no civilization in such a large universe and such a high probability?’

“But… If there is a civilization, why can’t we observe it?”

“Here… What went wrong?”

“Oh my God!”

“Assi, oh my God, I’m me… I’m in a cold sweat!”

“Shhhh

“Why is that?”

“Why the hell is that?”

“……”

The entire auditorium was filled with horror and suspicion.

At this time, through the live broadcast, it was transmitted to TV stations all over the world.

Countless people around the world were silent and stunned at this time.

No one would have thought that behind this, there was a hidden one that no one thought of – paradox!_
