What? Ultraman is lifelong?

The Oort cloud wrapping the solar system is filled with many inactive comets. This mysterious spherical cloud, also known as the comet cloud in the human world, steadily wraps everything in the solar system all year round.

A beam of light that looked like a meteor passed through the mysterious spherical cloud composed of the endless nebula remnants of the sun and its planets, and without any stop, once again broke through the celestial bodies outside the orbit of Neptune in the solar system and near the ecliptic plane. The dense disk-shaped area, the huge asteroid belt on the edge of the solar system - the Kuiper Belt.

Finally, this light entered the observable range of humans, but when human equipment was about to notice it, it accelerated again, and then came the eight major planets, the asteroid belt between Mars and Jupiter, and various satellites. the moon, and finally the earth.

The light from the universe broke through the atmosphere, and then stayed for a moment above a neon baseball field. Before a caddy in the baseball field turned around, the light disappeared into the clouds again, like a jet plane. Traces of the passage appeared in the clouds and disappeared over a building with a silver-white metallic texture in the Pacific Ocean.

Castor and Masaki Keigo have been waiting for a long time, feeling the light returning from the universe. The two looked at each other, and then Masaki Keigo turned off all the electronic equipment in the laboratory, "Do Sawai and the others know?"

"I know." Castor glanced at the figure who appeared in the laboratory, "But they also know that we still need to judge whether humans can currently touch these things."

Asuka wiped the sweat from his forehead, walked to the edge to get a glass of water, and then took a big sip. The familiar and unfamiliar feedback from human organs gave him some aftertaste. Castor could see When Asuka came out, he wasn't thirsty. He was just trying to find his human side in this way.

Masaki Keigo casually took out three glasses and a bottle of whiskey from the corner of the laboratory, and then took out a box of ice cubes from the refrigerator where the experimental reagents were supposed to be placed. He tested the ice cubes through the ice box with the back of his hand. temperature, then he put the ice cubes into the cup with satisfaction, and then poured the amber wine into the cup.

"Hmph! Let me, Masaki Keigo, pour the wine myself." He shook his head, "That's you."

"Does whiskey have sake?" Kazuma Asuka asked a little embarrassed, "I used to be a pilot after all, and I'm considered a middle-aged man at my age."

"This thing can help you regain your human feeling as quickly as possible." Masaki Keigo said with some emotion, "This thing can help you break away from the rationality of light as quickly as possible."

Seeing Asuka Kazuma hesitate, Castor directly put the cold wine glass into the opponent's hand, then picked up a glass himself, and watched Masaki Keigo also pick up the last glass.

There was no clinking of glasses, the three of them just drank the wine in their glasses silently.

The people I choose are indeed different, Casto thought as he looked at their drinking postures.

Although Asuka Kazuma said that he was a pilot, when he actually drank, he drank all the liquid in the cup quickly.

Masaki Keigo is the complete opposite. Every sip he takes seems to be measured, with exactly the same frequency, exactly the same intake, and a face that will never change color, although he himself said that alcohol will make him lose his rationality. state, but Casto felt that there were many things that could make this guy lose his mind, but there would never be alcohol in them.

"Are you raising fish?" Masaki Keigo frowned and looked at the amount of liquid in Castor's cup. "If you don't know how to drink, I can give you milk. You don't need to spit it in, right?"

"That's because the ice cubes melted!" Casto curled his lips, "And compared to you, I'm just a child."

"Hmph! Who knows?" Masaki Keigo rolled his eyes at Castor, then turned his head and looked at Asuka Kazuma, who was already in a daze.

Asuka and Kazuma were called back from the universe by them.

The situation in the universe is different from what Masaki Keigo thought, at least that's what Castor told him.

In Masaki Keigo's original vision, based on the drawings of the cosmic empire, there should be a large number of unpredictable interstellar civilizations in the universe.

So according to common sense, there should be more cosmic civilizations appearing on the earth than there are now, but this is not the case.

And when Masaki Keigo used a computer to calculate, the result was not like this.

In the process of calculating the civilization of the universe, Masaki Keigo actually added the variable of the dark ruler in the deep sea. After all, he also knew how many civilizations the existence of this thing could block, but even so, the number was still wrong.

Too few. Even if there are ten more dark rulers, there will still be too few alien civilizations appearing on the earth.

Masaki Keigo had to admit that under this theory, there were still 'rules' in this universe that he didn't know about.

The Fermi Paradox, which should have expired in human society, reappeared in Masaki Keigo's calculations.

The Fermi Paradox is a scientific paradox about aliens and interstellar travel. This paradox only raises one thing, that is, between the high possibility of the existence of extraterrestrial civilization and the fact that there is a lack of proof in reality. The incomprehensible contradictions that exist.

The original idea for the Fermi Paradox was not proposed by Fermi, but came from an unpublished manuscript written by Konstantin Tsiolkovsky in 1933.

As the founder of astronautics and later known as the father of aerospace, he wrote: "People deny the existence of extraterrestrial civilizations because, if extraterrestrial civilizations really exist, two things should happen: One is that they should have visited the Earth, and the other is that they should have sent us some signals of their existence."

Of course, if this is the case, this question does not form a paradox, but is just a simple hypothesis deduction.

Because based on the fact that humans have not yet discovered extraterrestrial civilization and Tsiolkovsky's theory, the conclusion that should be drawn is that "there is no extraterrestrial civilization in the universe", and there will be no contradiction.

It was not until 1950 that Fermi came up with the question of where alien civilizations were while talking with his colleagues.

They also thought that if aliens exist, humans should have discovered aliens. But unlike Tsiolkovsky, Fermi made a simple calculation after the discussion and proposed that the probability of the existence of alien civilization is very high. The question therefore becomes a paradox.

After Fermi's death, the above content was published by his colleagues, and this paradox is also known as Fermi's Paradox.

N=NgxFpxNexFlxFixFcxFL.

The N on the left represents the number of observable extraterrestrial civilizations that should exist in the Milky Way. The first three items on the right represent the total number of planets in the Milky Way, and the following items represent multi-level conditional probabilities that extraterrestrial civilizations will be born and send signals. The required probabilities for each step are multiplied to get a total probability.

The two most important contradictory arguments of the Fermi Paradox are:

1. There should be a large number of alien civilizations in the Milky Way.

2. Humanity has observed no signs of extraterrestrial civilization.

The Fermi Paradox was broken on the eve of the establishment of TPC.

One of the reasons for the establishment of TPC is that after humans entered modern society, a large number of unknown cosmic radio waves were continuously detected. At the end of the last century, scientific research institutions in various countries and teams led by Director Sawai all experienced it personally. A true cosmic event.
