Spaceship Accident

The "sizzling" noise in the earphones became louder and louder, and seeing that several observation equipment had been damaged by strong radiation, Zhang Yuan hurriedly said loudly: "Temporarily shut down these equipment... only keep the astronomical observation equipment, and record all astronomical observations. Data! By the way, how much has the temperature on the surface of the spacecraft increased?"

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

The rotation axis of η Carina star is aligned with the direction of the earth, at the moment of supernova explosion, the biggest catastrophic gamma ray burst in the universe will be ejected from the rotation axis.

According to estimates, the energy of gamma-ray bursts is equal to or even more than the sum of the energy released by the sun in its entire 10 billion-year life cycle!

After 2700 voyages, the spacecraft can theoretically escape the attack range... So this time the supernova explosion will not have a great impact on the spacecraft, at most it is 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 is a little bit off-angle, and it's aimed right at the spacecraft?

If the spaceship is affected, 500,000 people will die!

"Damn it, it exploded at this time!" Zhang Yuan cursed fiercely in his heart, and frantically operated the instruments to check the overall condition of the spacecraft.

The light in front of him became more and more intense, and Zhang Yuan held his breath. This was the first time he witnessed a supernova explosion with his naked eyes.

Through the thick glass, the light shone on the floor, and the floor quickly became extremely hot.

Colleagues around looked at the various observation data jumping in the computer and were constantly reporting the situation.

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

"The amount of radiation in the observatory has greatly exceeded the standard... The energy of a single photon is about 400,000 times that of sunlight..."

"The temperature on the sun-facing side of the spaceship has risen to 400...500...600 degrees Celsius...it's still within the tolerable range." After about

20 minutes of testing, everyone breathed a sigh of relief, "The temperature will not rise any further in the short term. Yes, 600-700 degrees Celsius is already the limit, and I don't know if it will erupt again." "

If it's just like this...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 too much damage to the spacecraft. He is considering whether to inform the conscious population on the spacecraft to come to the observatory to witness this supernova event.

However, following the principle that one thing more is worse than one thing less, this idea was quickly abandoned.

Everyone recovered from the panic at the beginning, and then recorded all kinds of data very excitedly. Maybe the scientists who wake up in the future can discover new physical phenomena in various high-energy rays?

This kind of supernova explosion with a mass of 100 times the sun can be described as a rare event with a small probability of 10,000 years. It can only last for a few hours, and last for a week at most. Because the mass is too large and the explosion is too violent, it may not even be possible to form a black hole afterwards, because almost all the matter is ejected violently at that moment.

Human beings know very little about the explosion of this massive star, and a complete record of the entire explosion process will be of great benefit to future research.

Zhang Yuan suddenly remembered something, and sighed: "Assuming the calculation is accurate... I don't know what happened to the earth civilization that was targeted, and whether it would be devastated by the supernova." Several colleagues

chattered Tongue, "I think there may be some impact, but it will not hurt the bones."

"Earth civilization is such an old-fashioned interstellar civilization after all. Even if technology stagnates, it will not be what it used to be. If the sun exploded, There may be no way to resist it at close range, but it should be no problem against a supernova 7,000 light-years away..."

"We have been taking preventive measures for this disaster."

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

Zhang Yuan clicked Nodding, "I wish them good luck, all we can do now is take care of ourselves."

The 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. There is no way for the speed of photons to reach the absolute speed of light in the true sense.

Some neutrinos, on the other hand, travel close to the speed of light and barely interact with any matter.

Therefore, in the chasing battle that lasted for more than seven thousand years, the fastest neutrino can often win for a few hours, bringing the first warning to human beings.

In the midst of this heated discussion, Zhang Yuan suddenly felt a slight vibration.

He hurriedly pressed his hand to the ground and felt it carefully. The vibration was subtle, faintly visible, and it seemed to have a buzzing feeling when it was transmitted through the machine.

There was a "click" in his heart!

The Earth Era is an extremely stable spacecraft, especially when the nuclear fusion engine is completely shut down and relies on inertial navigation, it is almost impossible for such a vibration to occur!

Something may have happened!

Zhang Yuan gasped: "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 activated the precious jet device in the space suit.

Flying quickly to the middle of the track train, Lin Xuanxuan's panicked cry came from the earphones: "...it's not good!" "...

a room in M ​​District is broken, and a large amount of helium filled inside is leaking out! Zhang Yuan, come quickly!"

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

The temperature is only 600 degrees... how is it possible? !

Typically, when a living area is idle, the air inside is replaced with helium to prevent oxygen from oxidizing the equipment inside. Area M happens to be an idle area. Is it because of negligence in usual maintenance?

impossible.

He frowned deeply, "I see, you should find a place to hide first, don't join in the fun! By the way, close all the air pressure gates near the hospital!" The next second, another soldier

connected A dedicated line was set up: "Captain Zhang, a peripheral room in Area M suddenly ruptured, and we are trying to close the nearby air pressure door!" "Do you know the specific

reason?"

"We are investigating and monitoring..."

Another series of miscellaneous messages The sound enters the earphones.

Zhang Yuan was disturbed by all kinds of noisy noises, and Zhang Yuan yelled into the earphone: "Everyone, put on space suits and stay away from Area M!

" All the surrounding air locks are closed!"

"Don't feel sorry for the leaked air! Don't go and look, if you are sucked out, you will die!"

He didn't know what happened, he just knew that life The district seemed to be hit by something, and then made a gap.

But...

how is it possible?

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

Could it be that the thing hitting the spaceship is moving close to the speed of light? That would be possible almost simultaneously with the supernova explosion.

But if it is a matter moving close to the speed of light, the spaceship can be turned into real interstellar garbage in one shot, instead of just breaking a small gap like it is now!

Or maybe...a meteorite happened to hit the spacecraft, and it has nothing to do with the supernova this time?
