Harry Potter’s Morning Light

  Chapter 1083 The Son of Stardust

  When the sun dies, the hydrogen element in its core will be exhausted and everything will begin to cool down.

  The internal thermal pressure cannot support its internal structure, gravity dominates, and its inner core continues to collapse.

  The collapse will increase the core pressure of the sun, causing the gas to expand and increase in volume in an instant, until it becomes a red giant star.

Its radius will extend to the earth and swallow this beautiful planet. Compared with the entire universe, the sun is insignificant. Even standing outside the Milky Way to observe, the sun may not be found at all, because it is too small, just a medium-sized one. Mass stars.

  Iron is not rare on the earth, even in everyone's body. It is precisely because of iron that human blood has the smell of rust.

Once a red giant star is formed, when the outer region rapidly expands, the helium core shrinks inward by the reaction force, and the compressed matter continues to heat up. However, a star with a mass like the sun can only go from hydrogen to helium when its life ends. If it fuses to carbon, the final carbon core will not continue to fuse.

   Even more massive stars can continue to burn carbon nuclei when the hydrogen and helium are burned out, producing heavier elements such as sodium and magnesium, all the way to iron.

  Elements with atomic numbers greater than iron can undergo nuclear fission reactions under certain conditions, and eventually iron is produced. And elements with atomic numbers less than iron can undergo nuclear fusion reactions under certain conditions, and eventually iron is also produced.

  Iron is just in the critical state of fusion and fission, it can neither fusion nor fission reaction, so in the end only iron is left.

  The iron on the earth and humans may have come from billions of years ago, a large star at least 8 to 29 times larger than the sun.

  The iron nucleus at the center of the red giant has a lot of electrons. When the star’s lifespan is about to end, the nuclear fusion reaction becomes weaker. Gravity squeezes the iron nucleus and electrons are squeezed into the nucleus.

  Due to electron capture, the number of electrons is reduced, pressure and gravity break the balance again, and gravity collapse occurs. This process is about 0.1 seconds, and then the supernova explodes.

  The extreme high temperature and high pressure of the supernova big bang will synthesize elements heavier than iron, such as gold, but in this case, white dwarfs will not be formed.

  The white dwarf is formed at the end of a star with the same mass as the sun. If it is more than 30 times the mass of the sun, then the star will form a black hole at the end of its evolution. No matter can escape its gravity, even light.

   After a supernova explodes, a neutron star will be formed. The debris produced by the previous generation of stars is captured by the second generation of stars. Some elements are pulled into the "furnace" and some elements form planets, and then a galaxy similar to the solar system is born.

  These are all discovered by modern Muggle scholars. Humans in the fifteenth and sixteenth centuries did not have a Hubble telescope. Mercury is called Mercury because it moves fast, so it is called the "messenger".

  Observing Mercury from the earth is blue, reminiscent of the blue sea, but this planet closest to the sun actually has no drop of water, just like mercury. Although it can flow like liquid, it is a metal. Whether it is mercury or Mercury, flow and speed are their important characteristics.

  Severus is an experimentalist, as Sirius said, he likes to tinker with his chemical tools in the cellar.

  Pomona is a speculationist. The ancient alchemy manuscripts have a lot of encrypted content, and there are many complex metaphors and symbols. Unless you have the key to open, you can't see the connection between the context.

  Guessing the meaning of these manuscripts is also part of the practice. The same is the swan. Sometimes it represents arsenic, sometimes it represents Mercury. Almost all alchemists use obscure myths and metaphors to describe their experiments.

  Pomona believed that Tom had found the right key by chance, and Severus did not believe that there was such a coincidence that he would use the slow but safe method of experimenting one by one.

Gold, silver, copper, iron, tin, lead, and mercury are the seven sacred metals in alchemy, but they actually used much more metals than these seven metals. If Mongoñez Hagrid uses such a simple encryption method, the treasure will be early Was taken away.

  The key is that the mercury content in a gold coin cannot exceed a quarter of an ounce. If the seven sacred metals are really used, then one gold coin will have an excessive amount of mercury.

  Leo represents gold. It seems to be easy to guess, but Virgo can’t use mercury. Harvest wheat needs fertilizer. Potassium seems to be a possibility. Plants also need trace elements.

Pomona looked at the "cheating" note. Slytherin worked so hard to win the Academy Cup in the first school year. At the end of the semester banquet, the old lion added more than 400 points in one breath, and the trophy he was going to get changed hands. .

  Even the Weasleys are eccentric, and Ron has never received much attention from Pasido.

  Severus has never been favored by his elders, so he doesn't know this "little trick".

  He is very good, but he doesn’t like Albus. Albus took him out of Wisengamo’s trial with a single word, which shows how powerful and prestigious the old fool is.

  But in school, he just wanted to fight Albus. What about his Slytherin's cunning?

  There are many books on alchemy in the Black family's collection. The more she reads, the more upset she gets.

   So she put down the book and stared at the other "bookworm". He was so intent that she took out her pocket watch and took a look. It was already eleven o'clock.

   "It's time to rest, let's go back to our room to sleep."

   "You haven't got enough sleep after two months?" Severus said without looking up.

   "I am worried about your health."

   "Wait for me to finish reading this paragraph."

  Pomona was angry. He wanted to steal these books the last time in the Black House. If this continues, he will become a "Frankenstein".

   "Let's go!" She pulled his sleeve, the old bat remained unmoved.

   "What content did you see so interesting?" She also watched it curiously.

"Remember Fox? It swallowed a spell, but didn't die. Instead, it was reborn. The phoenix, like the lighthouse jellyfish, can live forever as long as it is not eaten." Severus said, pointing to the phoenix in the book. "Phoenix does not have as many natural enemies as jellyfish. I have always wondered why there are so few phoenixes?"

   "Do you want to raise one?"

  Severus smiled weirdly, "Why do you have this idea?"

   "It's cool to have a phoenix pet."

  Severus shook his head, "The appearance of this animal is not in accordance with the laws of nature. If the book is true, the phoenix is ​​the same as the basilisk, and is a product of alchemy."

   "I know that there is a phoenix in Nick Lemay's book, but I don't think it is like a life created by alchemy."

   "That's why I have to finish reading and then leave. Can you clean up something for me?"

   "I heard that when Dumbledore needs a Phoenix, it will always appear." Pomona said.

"How did you know?"

  "Have you had a picnic with the old fool?"

  He frowned, "Why should I have a picnic with him?"

   "You only have business to talk to, right, and Harry?" Pomona stared at him and shook her head.

  "You have a good personal relationship with him, did he tell you how this phoenix came from?"

   "I didn't ask!" she said confidently.

   "Awesome, what do you talk about on a picnic? Is this candy really sweet?" he said with a smirk.

   "We talk about students and their growth." Pomona said, "Who gets married, whose child is going to school again."

   "What's the point of such a chat?"

   "Of course, because we are all children of the stars." Pomona stared into his eyes and said, "We are related to the stars in the sky."

  Severus looked at her and shook his head, "You are crazy."

  But he threw the broken book away, and then he got up, put his arm around her shoulders, and left the secret room.
