Chapter 167

The "Zizi" noise in the earphone became louder and louder, and he saw that several observation equipment had been damaged by strong radiation. Zhang Yuan quickly shouted: "temporarily shut down these equipment... Only keep the astronomical observation equipment and record all astronomical data! By the way, how much did the surface temperature of the spacecraft rise? "

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

Ship base η The rotation axis of the star 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 rotation axis.

According to estimation, the energy of gamma ray burst is equivalent to the total energy released by the sun in its entire 10 billion year life cycle, or even more!

After 2700 voyages, the spacecraft can theoretically escape from the attack range... So this supernova explosion will not have a great impact on the spacecraft. At most, it is equivalent to exposure to a little stronger sunlight for a while.

But... What if?

What if the calculation is wrong?

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

If the ship is affected, 500000 people will die!

"Damn it, it exploded at this time!" Zhang Yuan scolded fiercely in his heart and hurriedly operated the instruments to detect the total condition of the spacecraft.

The light in front of him was getting stronger and stronger. Zhang Yuan held his breath. It was the first time he witnessed the explosion of a supernova with his naked eye.

Through the thick glass, the light shines on the floor, and the floor soon becomes extremely hot.

Colleagues around are constantly reporting the situation, looking at various observation data jumping in the computer.

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

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

"The temperature on the sunrise side of the spacecraft has risen to 400... 500... 600 degrees Celsius... It is still within the tolerable range."

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

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

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

Since the supernova explosion will not cause much damage to the second spacecraft. He is considering whether to inform the conscious population on the spacecraft 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 recovered from the initial panic, and then they were very excited to record all kinds of data. Maybe scientists who wake up in the future can find new physical phenomena in all kinds of high-energy rays?

This supernova explosion of 100 times the mass of the sun can be described as a rare small probability event in 10000 years. It can only last for a few hours or a week at most. Because the mass is too large and the explosion is too violent, it may not even be able to form a black hole afterwards, because almost all the matter ejected violently at that moment.

Human beings know little about the explosion of such a massive star. A complete record of the whole explosion process is very beneficial to future research.

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

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

"After all, earth civilization is such an old interstellar civilization. Even if science and technology stagnates, it has long been different. If it is a solar explosion, you may not be able to resist it at close range, but there should be no problem against supernovae 7000 light-years away... "

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

"By the way, if they have neutrino observation devices, they should find the disaster a few hours early and arrange emergency refuge."

Zhang Yuan nodded. "I hope they have good luck. All we can do now is take care of ourselves."

Neutrinos from supernova explosions may indeed run faster than gamma rays.

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

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

Therefore, in the chase war of more than 7000 years, the fastest neutrino can often win for a few hours and bring the first alarm to mankind.

In this heated discussion, suddenly, Zhang Yuan felt bursts of slight vibration.

He quickly pressed his hand on the ground and carefully felt the subtle and looming vibration, which seemed to be buzzing through machinery.

His heart "cluttered" for a moment!

Earth times is an extremely stable spacecraft, especially when the nuclear fusion engine is completely turned off and depends on inertial navigation, it is almost impossible to have such a vibration!

Something may have happened!

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

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

When she quickly flew to the rail train, Lin Xuanxuan's panic cry came from her headset: "... No!"

"... a room in area m is broken, and the helium filled in it is losing a lot to the outside! Zhang Yuan, come quickly! "

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

The temperature of only six Baidu... How is it possible?!

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

No way.

He frowned deeply. "I see. You should find a place to hide first. Don't go there to join the fun! By the way, close all the air pressure gates near the hospital! "

The next second, another soldier connected to the dedicated line: "Captain Zhang, a peripheral room in zone m suddenly burst. We are trying to close the nearest air pressure door!"

"Do you know the specific reason?"

"We are investigating surveillance..."

A series of miscellaneous sounds are transmitted into the headphones.

All kinds of noisy noise upset Zhang Yuan. Zhang Yuan shouted at his headphones: "everyone, put on your spacesuit and stay away from zone m!"

"Turn on the air extraction pump, extract the air from the surrounding area, and close all the surrounding air pressure gates!"

"Don't feel sorry for the leaked air! Don't go over and see. If you're sucked out, you'll be dead! "

He didn't know what had happened. He just knew that the living area seemed to have been hit by something and then made a gap.

But

How is that possible?

At this moment, Zhang Yuan thought a lot in his heart.

Is it possible that what hits the spacecraft moves close to the speed of light? Then it can come almost at the same time as the supernova explosion.

But if it is a material moving close to the speed of light, it can turn the spacecraft into real interstellar garbage at one shot, instead of now, it just breaks a small gap!

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