Chapter 8 The Ending Star

"Supernova?"

   Lu Yu, who could only be confined in a narrow cockpit for half a month, has been crazily supplementing his knowledge of astronomy these days. In his opinion, he is jumping between the stars, and the subject he is most likely to promote is only astronomy.

  According to the current level of human science and technology, the cognition of the universe is still at a very elementary and primitive level. At present, the celestial bodies outside the solar system are all based on observations and guesses, or models that are calculated and simulated.

  If some typical celestial bodies can be found, such as black holes, galactic centers, or super celestial bodies such as neutron star supernovae for close observation, then this information will have an inestimable role in promoting Blue Star's astronomy.

  The outer armor set by the Silver Star can completely withstand the extreme environment around the super celestial body. Observing in the cockpit is more like overlooking the phenomenon from a high dimension, and there is no need to worry about being instantly evaporated by high-energy rays.

  Looking at the blue stars outside, Lu Yu drifted in the universe for more than half a month, and his already cold mood was a little excited.

  Supernovae lie at the intersection of many different branches of astronomical research.

  As the final destination of many kinds of stellar life, it is an important part of testing the current theory of stellar evolution.

  The phenomena observed at the moment of explosion and after the explosion involve various physical mechanisms, such as neutrino and gravitational wave emission, combustion propagation and explosive nucleosynthesis, radioactive decay, and the interaction of shock waves with peristellar matter, etc.

  And the remnants after the explosion, such as neutron stars or black holes, expanding gas clouds play a role in heating the interstellar medium.

   Meanwhile, supernova explosions play an important role in producing the heavy elements in the universe. Nuclear fusion in the red giant phase of stars produces a variety of intermediate-mass elements heavier than carbon but lighter than iron. Elements heavier than iron are almost all synthesized during the explosion of a supernova, and they are thrown into the interstellar space at a high speed. The gold on the blue star is basically born in the nuclear fusion of a supernova explosion.

   In addition, supernovae are the main spokesmen for the chemical evolution of galaxies. In the evolution of early galaxies, supernovae played an important feedback role, and the loss of galactic matter and the formation of stars may be closely related to supernovae.

   Therefore, observing supernovae has always been an important observation topic for the major astronomical telescopes on Blue Star.

   And now Lu Yu can actually come to a supernova that has reached a critical state. This may be the miracle he has been pursuing!

   "How long will its critical state last? If the moment of supernova explosion and the formation of black hole can be observed, it will be a milestone step for blue star astronomy, right?"

  Lu Yu eagerly asked the professor in the video, but the professor over there nodded suddenly, then seemed to remember something, opened his mouth and was speechless.

   Lu Yu keenly captured this expression, and then realized the fatal point, his enthusiasm instantly cooled down.

   This is a star.

  Even for a star that is about to die, the moment it is about to end may be the length of a lifetime for human beings.

  Time is so cruel, especially for Lu Yu who is about to have no food.

  In silence, Lu Yu showed a surprised expression again.

  Because a translucent holographic panel appeared in front of his eyes, with reminder text displayed on it.

  【The supernova in front of me has reached the critical point, and after 46 hours, this star will come to an end】

  【Trigger system task mechanism. 】

  【During the mission, the point reward will be doubled】

  【Please select a task】

   At the moment when Lu Yu was close to the end of his life, this black technology realization system that had been awakened for more than half a month responded for the first time.

   46 hours left? ! Instead of more than a thousand years?

   So, I can still save it!

  Lu Yu quickly clicked on the [Task] icon on the screen, and soon four tasks appeared on it for him to choose.

  Mission 1: Supernova Flash

  In the cognition of low-level civilizations, supernova explosions seem to be the most peculiar celestial bodies in the universe. It may be a small-scale reproduction of the origin of the universe, or it may be the source of all life elements.

  Look at it for an important piece of the astronomy puzzle!

  D-level rewards are used to calculate the degree of completion of astronomical achievements and to settle points.

  Task 2: New material library, hurry up!

  Superheavy elements are scarce in planets, and neutron stars and white dwarfs are extremely difficult to mine. In the eyes of intermediate civilizations, supernova explosions are undoubtedly the best time to obtain large amounts of rare elements.

   Get busy and enrich your material reserves!

  C-level rewards, use the collected superheavy elements to calculate the degree of completion and settle the points.

  Mission 3: The newborn black hole

  The nascent black hole is too naive for low-level civilizations, but just right for high-level civilizations.

   Capture it, transform it!

  B-level rewards, the points are settled according to the completion of the black hole transformation.

  Mission 4: It’s just a toy

   A critical state supernova is a shiny marble, a nice toy.

   Freeze it forever and add it to your collection!

  A-level rewards, the points are settled according to the degree of completion.

   After browsing through the four tasks, Lu Yu directly chose task one without even thinking about it.

  The other three tasks can be understood by looking at the simple task introduction. Is that a task he can complete now?

  No such ability!

  After decisively accepting the mission one, the personal panel of the system immediately changed.

  Host: Lu Yu

   Points: 0

  Mission: [Supernova Flash: 0%]

  Currently owns a black technology product: [Silver Star]

   On the task column, Lu Yu can check the content, except for the task brief that he saw before, which is the progress of the task.

  【Supernova Flash】

  【Progress: 0%】

  【Achieved results: None】

  【Settlement】

   Here, Lu Yu also got an unexpected harvest. If he chooses [Settlement], even if the task progress is only 0, he can still settle it in advance. The consequence is that he should not expect to get points anymore, right?

  Lu Yu understands that this task may be his only chance to survive, how can it be settled with zero progress?

  The development of scientific theories and hypotheses is inseparable from observational phenomena, and this blue star is the best astronomical observation material.

At this time, he was very fortunate to have established a certain foundation of mutual trust with the country early on. Relying on his own strength alone, even if he recorded the moment of a worthless supernova explosion, it would be difficult for it to get attention, let alone promote the development of astronomy in a short period of time. develop.

  When Lu Yu shared the intelligence and mission with the country again, he soon got an unexpected reply.

   "We want to host the most grand global astronomy live broadcast for you!"

   "At that time, well-known astronomers from all over the world will be invited to witness the moment of the supernova explosion!"

  “Although science without borders has become a joke now, it should indeed be a moment that belongs to the civilization of all mankind!”

   "This is for you, but also for civilization. At this moment, we choose to open and share."

   Such a reply far exceeded Lu Yu's expectations, and he quickly figured out the meaning behind it.

  If the recorded data at the moment of the supernova eruption only stays inside, then how long it will take for the theories or conjectures promoted by it to be recognized and accepted by the human astronomy community, and Lu Yu has no time to wait.

  So it’s better for everyone to witness this moment together. As long as they can admit that the moment when Lu Yu shot the supernova explosion at close range is real, there will be no doubt that literature will open a new chapter that day!
