Materials science and technology are the cornerstone of the spacecraft manufacturing industry, which is why Hara and Lynn paid special attention to this discovery. Pen % fun % Pavilion www.biquge.info

Sooner or later, the civilization of the earth will face the test of the ultimate bug in the universe - gamma-ray bursts.

How will the earth's civilization survive?

Some scientists believe that in history, the earth has also been hit by large-scale gamma ray explosions, which caused the first mass extinction on the earth.

In the Ordovician period more than 450 million ~ 600 million years ago, when gamma rays "attacked" the earth, two suns seemed to appear in the sky in an instant, and the molecular structure of the stratosphere of the earth's atmosphere was destroyed, forming new nitrogen oxides, making the earth surrounded by a layer of "brown smoke", and the ozone layer was also seriously damaged. During this period, most of the organisms living on or near the surface, especially the shallow marine organisms, were almost extinct, while the deep-water organisms survived. This was the first mass extinction, in which 75% of all life was wiped out from the planet, much worse than the extinction of the dinosaurs, and this upheaval made vertebrates the new overlords of the planet.

In fact, gamma-ray bursts are especially common in the universe!

In the vastness of the universe, a "sun" is destroyed in the process of stellar cataclysm almost every second, and the variety of ways in which they die is far beyond what we currently know.

These processes include the pulsation of stars, collisions between stars, the collapse of a star into a black hole, or the explosion of a supernova. However, for a long time, these fierce events of extinction have been obscured by the seemingly calm night sky.

The gamma-ray bursts produced by stellar events are more like rifles than shotguns. As long as it is not very close to it, and it is not directly on the ballistic trajectory, it will not suffer a devastating blow. Over the centuries, the Earth has endured many "faint" gamma-ray bursts, all of which have been unharmed.

However, the Crisis Science team at the Alliance for Planetary Exploration (ACE) headquarters has confirmed that the gamma-ray burst produced by the extinction of the giant star WR104 this time is much more violent than the one during the first mass extinction.

The star WR104 is so close to the Earth that if we look at the star WR104 as a rotating firework, then we will see that it is facing the Earth without any tilt. This means that when it perishes, a strong beam of gamma radiation will travel through the solar system at the speed of light with the precision of a rifle bullet, which we simply cannot defend against, and it will destroy life on Earth in an instant, everyone will be reduced to a pile of bones, and finally the Earth will be empty.

During his dormancy, Yuan Haochen had dreamed of various scenes of the destruction of the earth one after another, and the words of the commander-in-chief were still in his ears.

"Yes, most of the extraterrestrial life in the universe may have been swept away by gamma rays, and maybe the earth civilization will have such a day."

The star WR104, which was stirred up by the energy generated by the explosion of another supernova, has turned into a giant cosmic bomb that can explode at any moment, and in the worst case, this bomb may have exploded, and a powerful gamma-ray explosion is rushing into the solar system, ready to harvest all life on Earth.

"Hopefully..., no, we must be in time, time is pressing, we have to hurry up a little more!!"

Yuan Haochen already had the decision to burn the boat and break the cauldron in his heart.

Because there were so many relevant materials stored, it took Yuan Chen and Lin En a whole week to translate all of them into Chinese, and then after eliminating the duplicate and irrelevant materials, they were packaged and sent back to the Earth Command Center.

Unfortunately, the relevant instruments and equipment found in the ruins cannot be brought back to Earth for the time being, so arrangements will have to be made in the future.

When he was done with this, Yuan Haochen's heart was also a little relieved.

"With this information, this time the Alpha Centauri galaxy exploration operation, we finally didn't come to the ...... in vain, cough~"

Lynn was interrupted by a violent cough.

"Go get some rest."

Yuan Haochen looked at Lin En's pale face, and hurriedly stepped forward to stroke his back and said with concern.

It was true that he had taken a good rest, and in the past 10 days of research work, he and Lynn had basically not rested. On the one hand, everyone wants to do their best to buy some time for the planet. On the other hand, this is not the earth, the day/night cycle is extremely irregular, and the daylight hours are so long that people will unconsciously neglect the rest time.

"Okay, I'm a little tired too, I'm going to take a rest...... ahem~"

Lynn didn't shirk this time, he was well aware of his physical condition at this time.

Yuan Haochen patted Lynn on the shoulder worriedly and said, "Don't take care of your health, we still have more difficult tasks to complete." ”

"Don't worry, I'll get better." Lynn managed to put a smile on her face.

"Let's go and rest."

"Okay, I'll leave the rest to you."

Yuan Haochen didn't say anything more, just silently looked at the back of Lynn who turned to leave.

.......

At the same time, a beautiful island in the middle of a lake on Earth.

The island is conical in shape, with a circumference of 1,900 meters, and is framed by towering granite. In the middle of the island stands an old castle full of heroic masculinity.

The castle, together with the surrounding walls and moats, forms an independent city. Because of its age, the tall gray walls are covered with dark green vines, and the extensive use of columns and vaults of various shapes gives the castle a more solid, balanced, and saturated aesthetic effect.

Hundreds of years have passed, and the castle has long since said goodbye to the sonorous sound of weapons, as well as the noise of banquets and wine.

Today, only the twists and turns of the castle, the cold and unforgiving water prison, the scarred torture instruments, the old palace-like rooms, and the dilapidated harp placed in the hall still tell the story and glory of the past.

The narrow windows of the castle building float in mid-air like countless pupils, and they are like black holes, making all kinds of questions cower in inexplicable fear.

On the wall of the corridor that connects the banquet hall are portraits of the castle's owners throughout the ages. The youngest one at the end of the corridor is the current owner of the castle, Just, with a faint smile on his lips, in fact, more like a sneer.

A rush of footsteps began to pass through the hallway, and a middle-aged man with a white beard was heading straight for the banquet hall with a gloomy face......
