Hand rubbing nuclear fusion live in the wilderness

Chapter 487 Artificial Buildings A Billion Light Years Away
The appearance of Betelgeuse's carbon flash made Han Yuan a little worried.

Judging from this photo taken, the carbon flash in the core area has penetrated the entire star.

And before that, there have been countless carbon flashes.

And it was this large-scale carbon flash explosion that caused Betelgeuse to eject a large amount of high-temperature plasma gas, which in turn covered the entire star.

What this means for a massive star in its later years is already apparent.

That is to say, the mass of Betelgeuse is large enough, twenty times that of the sun, to create and support such a large-scale carbon flash explosion.

If it is replaced by the sun, carbon flashes of this scale do not need many times, one time is enough to completely tear the entire star apart, and after throwing out a large amount of matter, it enters its old age and begins to evolve into a red giant star.

Won doesn't know how long Betelgeuse can last, but what can be met is that in his lifetime, there is a probability of more than 90.00% to see a Betelgeuse supernova erupt.

Although at present, the mass loss of Betelgeuse is roughly judged to be only one part in a million, which is insignificant compared to its own mass.

But every large-scale carbon flash explosion that can penetrate the star will reduce the "electron degeneracy pressure" of the inner iron core to a certain extent.

When the electron degeneracy pressure in the core is not enough to support the mass beyond the Chandrasekhar limit, the core inside the star can no longer support the entire star.

The extremely powerful gravitational force may directly crush the core when the next large-scale carbon flash erupts, triggering a supernova explosion or core collapse.

Although the eruption time of the carbon flash is extremely short, and the huge mass of Betelgeuse can quickly repair and fill the stars destroyed by the carbon flash, once the collapse reaction or the chain of supernova explosions start, it will basically not stop.

After carefully checking the whole photo, besides the carbon flash, Han Yuan also found some other details, all of which show that Betelgeuse is about to explode as a supernova.

"Xiao Ling, suspend the synthesis of other photos, and give priority to combining photos related to Betelgeuse."

After checking the first photo of Betelgeuse, Won quickly gave orders.

For the first batch of observation targets of the telescope, except for a few stars that are too far away and in special positions that require a long exposure time, all other astronomical targets have been photographed.

For example, there are three photos of the Pillars of Creation, and five photos of the Crab Nebula.

After all, the performance of the No. [-] outer space telescope in his hand is stronger than that of astronomical telescopes such as Hubble and Webb.

If Hubble takes ten days to expose the Pillars of Creation, Webb takes one day, and Zero takes only one hour.

The powerful performance gives more shooting opportunities, so naturally more than one photo is taken for some easily exposed stars and areas.

After waiting for about an hour, the second composite picture of Betelgeuse taken by the zero outer space telescope came out.

Han Yuan couldn't wait to open it, and found the core area where the carbon flash appeared before.

After searching carefully and confirming that the area he was looking for was correct, he was slightly relieved.

Judging from the second composite photo, the area where the carbon flash erupted before has returned to normal, that is to say, the carbon flash in the previous photo did not have an irreversible impact on Betelgeuse.

This is good news, at least the supernova explosion did not appear because of this carbon flash.

Of course, Won is not sure how long Betelgeuse can last, and he can only keep the No. [-] outer space telescope paying attention, sending back photos and data intermittently.

In this way, information can be obtained at the first time.

But to put it bluntly, apart from worrying about the pulsating neutron star formed after the explosion of the Betelgeuse supernova, he actually still has some expectations in his heart.

To be able to witness the whole process of a supernova explosion of a massive star can be said to be an extremely difficult one-in-a-million opportunity.

Especially this kind of observation distance is only 640 light-years, it can be said that as long as the performance of the telescope is strong enough, almost most of the details can be seen.

You can see how the star quickly ejects high-temperature plasma gas, and you can also see how the star dims little by little, and then instantly lights up the entire Milky Way, and you can even see how gamma rays envelop A powerful energy rushes to a certain place
For any person, seeing each other once in a hundred years is not in vain.

As the follow-up photos of Betelgeuse were synthesized, Han Yuan further confirmed that although Betelgeuse hadn't erupted yet, it was coming soon.

Of the six photos, clear carbon flashes can be seen in two of them. This ratio is quite exaggerated, which means that Betelgeuse is already on the verge of explosion and may become a supernova at any time.

As for the specific time, Won is not sure, but he still gave a rough data for these six photos, and the judgment is based on the frequency of carbon flash outbreaks.

Clear traces of carbon flashes can be seen in two of the six photos, and it took two days to take these six photos. That is to say, within two days, Betelgeuse had at least two carbon flashes that could penetrate stars. Once a day, no, maybe twice a day.

After all, the Betelgeuse he can photograph actually has only one side, and there is another side.

Calculated according to this speed and the matter ejected by each carbon flash, and counting the fusion reaction of Betelgeuse itself, Betelgeuse will suffer irreparable trauma in about 50 years.

That is to say, after the carbon flash, the mass of Betelgeuse's stars will not be able to fill up the stars torn apart by the carbon flash in time.

This will cause the core's "electron degeneracy pressure" to be seriously insufficient, and it will start to collapse directly, and it also means that it will start the last journey of life, a supernova explosion.

Hearing Won's speculation and calculation data, the audience in the live broadcast room lamented.

【what?Will it take another 50 years to explode? 】

[What are you kidding, I am 37 years old this year, and I will be 50 in 87 years. If I can live to that time, I will go to hell. 】

[Disappointing, I thought it was about to explode, but I didn't expect to have to wait another 50 years. 】

[50 years later, I hope my son can be burned to me in front of the grave. 】

[It seems that everyone is very pessimistic about whether they can live for 50 years (_)]

[996, 007 every day, that’s all, it’s pretty good if you can live to be 50 years old, okay?You have another 50 years to live, what are you dreaming about? 】

[I really didn't expect that the more advanced the technology, the more and more hours I go to work every day. 】

[It’s rare, there are still classes now, and when intelligent robots become popular in the future, you won’t even be able to go to work. 】

[Rare Jill, I'm bored, destroy it! 】

[Let's get a meteorite with a diameter of [-] meters, and everyone will ascend to the sky together. 】

Looking at these bullet screens, Han Yuan couldn't laugh or cry, shook his head slightly, and he explained:

"50 years is an estimated time. In fact, the time of Betelgeuse's eruption is unpredictable, because every large-scale carbon flash may completely tear the star apart."

"When I say 50 years, it is calculated based on the frequency of carbon flash explosions and the material ejected during each carbon flash explosion. After 50 years, even Betelgeuse will not supernova due to carbon flashes and other factors. It explodes, and it explodes because it ejects too much material."

"Theoretically speaking, Betelgeuse actually exploded as a supernova 590 years ago, but it will take 50 years for the light from the supernova to reach the earth."

In a word, Han Yuan made a fateful prophecy to Betelgeuse, and the audience in the live broadcast room were amazed.

【I see. 】

[It has exploded, but it takes time for the light to travel to the earth. 】

[Suddenly I sighed, how insignificant human beings are in front of the universe. Betelgeuse exploded 600 years ago, but we didn't know anything about it. 】

[I remember that the diameter of the universe is 940 billion light-years, right?In addition, the space of the universe has been expanding, and the speed is faster than the speed of light. That is to say, we will not be able to see the light sent back from the edge of the universe for a lifetime. 】

[In front of the iron wall of the speed of light, it is really too powerless. 】

[Is there any superluminal detector mirror? 】

[Anchor anchor, do you have a superluminal telescope in your hand? 】

In the live broadcast room, ordinary viewers kept discussing and sighing, but experts from various countries fell silent after hearing Won's speculation.

In front of the iron wall of the speed of light, it can be said that the Betelgeuse supernova, which can be said to be 'near at hand', exploded and they could not see it.This makes people feel powerless and small.

Although it has never been doubted that human beings will be trapped on this planet forever, when faced with the vastness of the universe, even a group of people who are at the forefront of technology have begun to doubt.

Is it true that one day, our footprints will be able to travel across the entire universe?

In contrast, Han Yuan didn't think so much. It's not that he didn't think about and lament these things, but it's useless to think and lament.

For technology, only if you slowly develop bit by bit, and move forward bit by bit, can you make progress.

The development of a civilization, unless it is opened up like him and can develop by leaps and bounds, otherwise it can only climb slowly.

Even super scientists such as Einstein and Newton can only push forward for more than a century.

Han Yuan ignored the exclamation in the live broadcast room, and he methodically checked the photos sent back by the No. [-] outer space telescope.

For him, this is a kind of enjoyment. The wonderful scenery of the universe, whether it is a huge nebula or a star that breeds life, is presented to his eyes one by one.

In particular, the Pillars of Creation, the Crab Nebula, and the Great Nebula in Carina are so breathtakingly beautiful under the exposure of infrared radiation.

Suddenly, in a photograph of a star, Han Yuan's pupils shrank suddenly, and he saw something that he himself felt incredible.

This is a very obvious artificial object that wraps around a small half of a star. It presents a fairly regular hexagon as a whole, and there are two huge cavities in the central area.
