Chapter 162

The "Zizi" noise in the earphone is getting louder and louder. Seeing that several observation devices have been damaged by strong radiation, Zhang Yuan quickly said in a loud voice: "turn off these devices temporarily Only keep astronomical observation equipment, record all astronomical data! By the way, how much has the surface temperature gone up? "

The sense of crisis rose to the extreme, and his breathing became heavy.

The axis of rotation of η star on the base of the ship is aligned with the direction of the earth. At the moment of supernova explosion, the biggest disaster in the universe - gamma ray explosion will be ejected from the axis.

The energy of the gamma ray burst is estimated to be equal to, or even more than, the total energy released by the sun over its 10 billion year life cycle!

After 2700 voyages, the spacecraft has been able to escape from the attack range in theory So this supernova explosion won't have much impact on the spacecraft. At most, it's just equivalent to being exposed to a little stronger sunlight for a while.

But What if?

What if the calculation is wrong?

What if this gamma ray burst deviated a little bit and just aimed at the spacecraft?

If the ship is affected, 500000 people will be killed!

"Damn, it exploded at this time!" Zhang Yuan heart hard to scold a, hurriedly operate the instrument, test the total condition of the spacecraft.

As the light in front of him became more and more intense, Zhang Yuan held his breath. It was the first time that he witnessed the explosion of a supernova with his naked eye.

Through the thick glass, light on the floor, the floor soon became extremely hot.

Colleagues around the computer looking at the jump of various observation data, is constantly reporting the situation.

"The temperature on the surface of the ship is rising!"

"The radiation in the Observatory has greatly exceeded the standard The energy of a single photon is about 400000 times that of the sun.... "

"The temperature on the Chaoyang side of the spaceship rises to 400 500…… 600 degrees centigrade It's still within the range of affordability. "

After testing for about 20 minutes, people were a little relieved, "the temperature will not rise again in a short time. 600-700 ℃ is already the limit. I don't know if there will be a second outbreak."

"If that's all It won't be a big problem. "

Zhang Yuan patted his chest. Fortunately, it was a false alarm.

Since the supernova doesn't cause much damage to the spacecraft. He is considering whether to inform the conscious population on board to come to the observatory to witness the supernova event.

However, adhering to the principle that more is better than less, he soon gave up the idea.

Everyone recovers from the initial panic, and then records all kinds of data with great excitement. Maybe the scientists who wake up later will be able to discover new physical phenomena in all kinds of high-energy rays?

This kind of supernova explosion with 100 times the mass of the sun is a rare small probability event in ten thousand years. It can only last for a few hours in a short time, and it can last for a week at most. Because the mass is too big and the explosion is too violent, it may not even be possible to form a black hole after the event, because almost all the matter is ejected violently at that moment.

Human beings know little about the explosion of this kind of massive star. It is very beneficial for future research to record the whole explosion process completely.

Zhang Yuan suddenly remembered something and sighed: "suppose the calculation is accurate I don't know what happened to the targeted earth civilization and whether it will be devastated by supernovae. "

"I think it may have some impact, but it won't hurt the muscles and bones," several colleagues said

"After all, the earth civilization is such an old interstellar civilization. Even if technology stagnates, it will not be what it used to be. If it's a solar explosion, you may not be able to resist it at close range, but it should be no problem to resist a supernova 7000 light-years away... "

"Preventive measures for this disaster have also been taken."

"By the way, if they had neutrino observation devices, they would have discovered the disaster a few hours earlier, and then arranged for emergency evacuation."

Zhang Yuan nodded, "I hope they're lucky. What we can do now is to manage ourselves."

Neutrinos in supernovae may indeed run faster than gamma rays.

This is because photons may interact with various particles in the universe during the long journey. The speed of photons can not reach the true absolute speed of light.

Some neutrinos are close to the speed of light and hardly interact with any matter.

As a result, in the pursuit of more than 7000 years, the fastest neutrinos are often able to win so many hours, bringing the first alarm to mankind.

In this heated discussion, all of a sudden, Zhang Yuan felt waves of slight vibration.

He quickly pressed his hand on the ground and carefully felt the subtle vibration, which seemed to have a buzzing feeling through mechanical transmission.

In his heart "clatters" once!The earth age is an extremely stable spacecraft, especially when the nuclear fusion engine is completely shut down and depends on inertial navigation, it is almost impossible to have such a vibration!

There may be something wrong!

Zhang Yuan took a cool breath: "you continue to record here, I'll go back and have a look!"

In the vacuum environment, there is no way to move at high speed. In order to speed up, Zhang Yuan even started the valuable jet device in the spacesuit.

As she quickly flew into the middle of the rail train, Lin Xuanxuan's voice of panic came from her earphone No

“…… There's a room in area m that's broken, and a lot of helium is leaking out! Come on, Zhang Yuan

Zhang Yuan was so excited that the wall of the spaceship was destroyed!

Just six hundred degrees of temperature How is that possible?

Generally speaking, when a living area is idle, in order to prevent oxygen from oxidizing its equipment, helium will be used instead of the air inside. Area m is just an idle area. Is it because of the negligence of usual maintenance?

It's impossible.

He frowned deeply, "I know. You should find a place to hide first. Don't go to join in the fun! By the way, close all the airlocks near the hospital! "

The next second, another soldier connected to the dedicated line: "Captain Zhang, there is a room outside the M area suddenly ruptured. We are trying to close the nearest air pressure door!"

"Do you know the specific reason?"

"We're investigating surveillance..."

There is also a series of miscellaneous sound into the headphones.

Zhang Yuan was upset by all kinds of noise. Zhang Yuan yelled at the earphone: "everyone, put on your spacesuit, stay away from the M zone!"

"Turn on the air pump, pump the air out of the surrounding area, and close all the surrounding air pressure gates!"

"Don't worry about the leaked air! Don't go to see it. If you are sucked out, you will die! "

He didn't know what was going on. He just knew that the living area seemed to be hit by something, and then he made a gap.

But

How is that possible?

In this moment, Zhang Yuan thought a lot.

Is it true that what hits the spaceship moves close to the speed of light? That way, it can come almost at the same time as the supernova explosion.

But if it is near the speed of light, it can turn the spaceship into a real interstellar garbage. It's not like this now. It just breaks a small gap!

Or maybe A meteorite just hit the spaceship, which has nothing to do with this supernova?
