Base Star, Military Commission Conference Room.

A very detailed stereoscopic star map is suspended above the conference table, with Betelgeuse as the center, a radius of 200 light years, like a layer of shell spherical shock wave to contain most of the holographic star map, the distance between the blue star below the star map and the shock wave is only a short distance.

Xie Guohui, from the National Astronomical Center, pointed at the blue light star with a stern expression and said, "According to our calculations, the distance between the shock wave and the blue light star is only 30 light years at most, and it may even be just over 20 light years. ”

Before the astronomers arrived, everyone made up some astronomical knowledge related to Betelgeuse, so no one asked stupid questions of common sense, but all listened attentively to the experts' explanations.

"Betelgeuse was discovered at the time of its discovery, which was already in the final stage of a star that could explode into a supernova at any time, and the astronomical community has been speculating about the final eruption time of Betelgeuse, but it did not expect that it will actually erupt much earlier than everyone expected." Xie Guohui pushed the glasses on the bridge of his nose, and sighed involuntarily.

With the current level of medical care, no matter how severe the eye disease is, it can be completely cured, even if the eye is completely necrotic, it can be replaced with a mechanical prosthetic eye, and glasses have been completely reduced to a tool for shading light and a dispensable decoration.

However, Xie Guohui's glasses are different, they allow the veteran expert to see the starry sky under the blue sky and white sun, and magnify it for a certain extent, and it also has the function of stabilizing the image, in short, it is a portable multi-functional small astronomical telescope.

This thing uses a lot of military technology, so it's expensive. Private purchases are a fatal affair, so only the best astronomical experts will be allocated a pair by the state.

Of course, he must not be able to see anything on the base star surrounded by nebula, so this old expert usually stays in the blue light star, and it was a complete accident to be able to invite him today.

After entering the cosmic age, the state has invested astronomical funds and forces in the study of astronomy, but limited to the technical level, in most cases, astronomical research still needs to use the naked eye and optical equipment for observation, so the top astronomers basically stay in relative safety. You can also see the blue stars in the starry sky.

At a critical moment in the expansion of the republic into the universe. Any top astronomer is a national treasure. Among the four planets owned by the Republic, only the base star is the safest, and if there is any unpredictable accident on the blue star, the strategic planning at the national level will probably be affected.

In order to resolve this contradiction. The Republic invested in the construction of the National Holographic Planetarium.

Over here. The information of the number of stars in the library can be called through the guò network for holographic restoration. It can also be shared with the space telescopes placed in each colony star in real time, and the real starry sky can be observed in an immersive way, so that you can stay at home. Look at the starry sky.

Professor Xie Guohui came back this time to participate in the inauguration ceremony of the holographic planetarium, but he didn't expect to avoid the crisis of the blue light star.

After the establishment of a holographic planetarium, there is no need to run to the distant blue star to study the starry sky, and there is no need to be separated from his family, which is safe and comfortable.

Because of this, a large number of experts and scholars in the astronomical field similar to Professor Xie's situation rushed back to the base star ahead of schedule, and only a small number of personnel were stranded in the blue star.

"Professor, I now want to know how much of an impact Betelgeuse will have on the blue star after it becomes a supernova!" Xu Shijie's two sword eyebrows raised slightly, "You also know, after all, there is a distance of more than two hundred light years between the Blue Light Star and Betelgeuse, although the explosion power of the supernova is very strong, but after flying over such a long distance, the power should have been weakened a long time ago, how can it still cause such a strict impact?" ”

"In the past, we thought that the impact range of a supernova explosion would not exceed 100 light-years, and the range that would have a fatal impact on habitable planets would be at most 30 light-years, but this number is based on speculation, and after looking at the number of stars detonated during the attack on the subhuman capital star, the calculated power range is 150 light-years, and we have reason to believe that the power radius of the previous 100 light-years is a misreading and underestimation of the power of the supernova explosion." ”

"Based on the current analysis number, how powerful will the supernova explosion be?" Xu Shijie couldn't help but ask.

"It's huge." Professor Xie said with difficulty, "You may have heard that the Sun has been traveling in the bubble of the local galaxy for more than 300 light years for 3 million years, and its current location is in the interstellar cloud, which is relatively dense in the bubble of the galaxy. ”

"In other words, the power of a massive star explosion can reach more than 300 light years, right?" Not talking about the key points made Xu Shijie very painful, and couldn't help but ask again, "What about Betelgeuse?" ”

Professor Xie replied: "Betelgeuse is much larger than the stars near the capital star of the Asians, and all the numbers we currently have come from the observations of astronomical telescopes, which are all hundreds of years old. ”

Speaking of this, the old professor pointed to the arc-shaped shock wave that was only a little distance away from the blue light star: "However, from the actual situation, the mass of Betelgeuse is greater than our previous estimates, but don't worry, the speed of the shock wave will not exceed the speed of light, so in less than ten or twenty years, the blue light star will not be affected, and we have a lot of time to withdraw from the blue light star." ”

"Is this necessary?" Xu Shijie asked, "Professor, I don't doubt your professionalism. Although the energy intensity of the shock wave is dangerous at the moment, not long ago, a battleship strayed into the inner layer of the shock wave, but quickly escaped, basically without any damage. You have also seen that the shock wave is still more than 20 light-years away from the blue light star, and after passing more than 20 light years, the shock wave intensity will definitely be much attenuated than now, and the blue light star is also a planet, and the protection will not be worse than a battleship, right? ”

Professor Xie sighed heavily: "The planet's magnetic field can indeed bring strong protection to the planet, in fact, the mother star of the blue star, the large blue star also has a very strong magnetic field, it can provide more powerful magnetic field protection for the entire galaxy, and the double magnetic field protection can make the shock wave threat to the blue star much stronger than the armor of a single battleship, but this does not mean that the blue star does not need to be relocated."
