The noise of "Zizi" in the headphones became louder and louder, and seeing that several observation devices were damaged by strong radiation, Zhang Yuan hurriedly said loudly: "Turn off these devices temporarily...... Keep only the astronomical observation equipment and record all the astronomical data! By the way, how much has the temperature on the surface of the spaceship risen? ”

The sense of crisis rose to the extreme, and his breathing couldn't help but become heavy.

The axis of rotation of the η star of the constellation is aimed in the direction of the Earth, and at the moment of the supernova explosion, the gamma-ray burst, the greatest disaster in the universe, is ejected from the axis of rotation.

The energy of a gamma-ray burst is estimated to be equal to, or even more than, the energy emitted by the Sun over its entire 10 billion year lifetime!

After 2700 voyages, the ship was theoretically able to escape from the attack range...... So this supernova explosion will not have much 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 the gamma-ray burst was off the rails and hit the spacecraft?

If the ship is affected, 500,000 people will be killed!

"Damn, it exploded at this time!" Zhang Yuan scolded fiercely in his heart, and hurriedly operated the instrument to detect the sum of the spaceship.

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

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

The surrounding colleagues looked at the various observations jumping in the computer and were constantly reporting the situation.

"The temperature on the ship's surface is rising!"

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

"The temperature on the sunny side of the ship rises to 400 ...... 500…… 600 degrees Celsius...... It's still within the affordable range. ”

After about twenty minutes of testing, everyone breathed a sigh of relief, "The temperature will not rise again in the short term, 600-700 degrees Celsius is already the limit, I don't know if there will be a second outbreak." ”

"If only that's all there is to it...... There won't be much of a problem. ”

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

Since a supernova explosion doesn't cause much damage to the spacecraft. He was considering whether to inform the sober population on the spacecraft to come to the observatory to witness the supernova extravaganza.

However, adhering to the principle that more is better than less, this idea was quickly abandoned.

Everyone recovered from the initial panic, and then they were very excited to record all kinds of data, maybe the scientists who woke up in the future will be able to discover new physical phenomena in various high-energy rays?

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

Mankind has little understanding of the explosion of such massive stars, and a complete record of the entire explosion process is very beneficial for future research.

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 devastating by the supernova. ”

Several colleagues said, "I think there may be some impact, but it won't hurt the bones." ”

"After all, the earth civilization is such an old interstellar civilization, and even if science and technology are stagnant, it will not be what it used to be. If the sun explodes, you may not be able to resist it at close range, but you should have no problem fighting a supernova 7,000 light-years away......"

"Precautions against this disaster have also been made."

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

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

Neutrinos that explode from supernova do have the potential to run faster than gamma rays.

This is because photons may interact with various particles in the universe during their long journeys. There is no way for the speed of a photon to reach the absolute speed of light in the true sense of the word.

Some neutrinos, on the other hand, have a speed close to the speed of light and hardly interact with any matter.

As a result, in the pursuit of more than 7,000 years, the fastest neutrino can often outperform for a few hours, bringing the first alarm to mankind.

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

He quickly pressed his hand to the ground, feeling it carefully, the subtle and looming of this vibration, transmitted through the machinery and seemed to carry a buzzing feeling.

He "groaned" in his heart!

Earth Age is an extremely stable spacecraft, especially now that the nuclear fusion engine is completely turned off and relying on inertia to sail, it is almost impossible for such a vibration to occur!

Something could have happened!

Zhang Yuan gasped: "You guys continue to record here, I'll go back and take a look!" ”

There was no way to move at high speed in a vacuum environment, and in order to speed up, Zhang Yuan even activated the precious jet device in the spacesuit.

Flying quickly into the rail train, Lin Xuanxuan's panicked voice was already heard in the earphones: "...... Oh no! ”

“…… There's a room in Block M that's cracked, and a lot of helium is leaking out! Zhang Yuan, come on! ”

Zhang Yuan was full of excitement, and the wall of the spaceship was destroyed!

The temperature is just 600 degrees...... How can it be?!

In general, when a living area is idle, helium is used instead of air to prevent oxygen from oxidizing the equipment inside. Area M happens to be an idle area. Is it because of the negligence of ordinary maintenance?

Impossible.

He frowned deeply, "I know, you guys find a place to hide first, don't go over and join in the fun!" By the way, close all the air pressure gates near the hospital! ”

In the next second, another soldier connected to the special line: "Captain Zhang, there is a peripheral room in Area M that has suddenly cracked, and we are trying to close the nearest air pressure door!" ”

"Do you know why?"

"We are investigating surveillance ......"

There was another series of miscellaneous sounds coming into the headphones.

All kinds of noisy noises made Zhang Yuan upset, and Zhang Yuan yelled loudly into the headphones: "Everyone, put on spacesuits and stay away from Area M!" ”

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

"Don't feel sorry for the air that leaks out! Don't go over and look at it, if you are sucked out, you will die! ”

He didn't know exactly what was going on, only that it looked like something had hit the living quarters, and then a gap had been made.

But......

How is that possible?

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

Could it be that what hits the ship is moving close to the speed of light? That would happen almost at the same time as the supernova explosion.

But if it is a matter moving close to the speed of light, it can turn the spaceship into real interstellar garbage with a single shot, instead of the current one, just a small gap!

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