Heterogeneous star

Chapter 396 [Discuss with physicists! 】

Han Shuo recalled the contents of the book "A Brief History of Time", and typed the following text on the keyboard: "At the time of the Big Bang, the volume of the universe was considered to be zero, so it was infinitely hot. However, the temperature of radiation varies with Decrease with the expansion of the universe. Up to this point, you have no doubts, right?"

"Yes, it is indeed reduced," David replied quickly, "I don't have any doubts, MR Han, please continue."

"Well," Han Shuo replied to David, "I think I don't need to talk about the following questions. In short, the central region of the star will collapse into a very compact state, such as a neutron star or a black hole. The outer part of the star Regions are sometimes blown out in huge explosions called supernovae, which can outshine all the stars in the galaxy by comparison. Heavy elements produced by some stars near the end of their lives are thrown back into the gas in the galaxy Go, provide some raw materials for the next generation of stars. I think, after I say this, Mr. David, you should already understand what I want to say? I don’t need to repeat the rest, right?”

Han Shuo believed that with David's comprehension ability, he could completely analyze what he was going to say next. After all, he was a famous physicist.Therefore, Han Shuo didn't want to continue wasting words on this issue, he wanted David to understand.

David on the other end of the network deposited about 5 minutes, and during this time only netizens who stayed up late and did not sleep responded one after another.

After about 5 minutes, David replied: "MR Han, you don't need to continue this question, I figured it out. Can you continue to answer my remaining questions? In the very early or very early days of the universe What exactly happens in the late period, when the gravitational field is so strong that quantum effects cannot be ignored? Does the universe have a beginning or an end at all? If so, what do they look like?"

"Mr. David, I remember the rest of your questions, and I haven't forgotten them," Han Shuo replied, "To answer these questions, I have to talk to you about the singularity theorem. David Sir, as a famous physicist, you must know the singularity theorem, right?"

"Well, I know," David replied, "the singularity theorem states that if the classical theory of general relativity is correct, then time began with infinite density and infinite space."

"Yes, that's it," Han Shuo typed a few words on the keyboard, "People can imagine that there are new laws that hold at the singularity, but, Mr. David, please think about a problem. Is it very difficult to even formulate such a law at this point?"

David, who was far away across the ocean, was taken aback by Han Shuo's question, and then fell into deep thought.

At this time, seeing that David did not reply, netizens couldn't sit still, and expressed their opinions online one after another.

"Why didn't David reply? Does he not agree with Han Shuo's theory?"

"I think David should be convinced by Master Shuo's theory."

"Wow, the conversation between Master Shuo and David is too professional, I can't understand it at all!"

"I don't know how serious it is!"

"By the way, why do I feel that Master Shuo's words are about to turn around? I vaguely feel that Master Shuo's next words may shock everyone."

"I think David should have been shocked by Master Shuo's unique insights into physics, otherwise he would not have spoken for so long."

"To be honest, as a graduate student majoring in physics, I can't fully understand the specific meaning of what Master Shuo and David said. I can only barely get a general idea."

"My God! Who would have imagined that a domestic entertainer would discuss such profound knowledge of physics with a famous foreign physicist? My God! This is really unexpected. I feel that this is a plot that hardly appears in novels." , but Master Shuo did it, he is really amazing."

"You said, is it possible that David felt that what Master Shuo said was unreasonable, so he simply went to bed and ignored Master Shuo?"

"Upstairs, what are you thinking about? Is there a time difference between David's side and ours? Isn't it midnight on their side? It's broad daylight on their side, so how can you sleep? I think it's too late. Wei may have been shocked by Master Shuo's theory, and he hasn't digested it for a while, so he didn't reply immediately."

"I have always liked studying physics, so I also like David very much. Now seeing David discussing physics issues with Mr. Shuo, I suddenly feel that Mr. Shuo's image in my mind is much higher. I will support him in the future. At the same time, David will support Master Shuo together."

"David hasn't replied for a long time. What's the matter with him? Did he suddenly do something else, or was he shocked by Master Shuo's answer, or was he not interested in Master Shuo's answer?"

"By the way, I suddenly discovered that David speaks Chinese well. Have you noticed?"

"Khan! From upstairs, do you know that David speaks Chinese well?"

"Hey, tell me, why did David go? Why didn't he reply?"

Netizens were talking about it, but David completely ignored these comments. He was sitting in front of a computer on the other side of the ocean, carefully studying what Han Shuo just said.Han Shuo's theory is really special, and he can see from the passage Han Shuo just replied to him that Han Shuo is trying to overthrow a point of view that has been recognized by the physics community for a long time.You must know that this is not a trivial matter, Han Shuo really has the courage!
Seeing that David didn't reply for a long time, Han Shuo replied: "And we didn't get any hints about what these laws should look like from the observation. However, what the singularity theorem really shows is that the gravitational field becomes so so strong that quantum gravitational effects become important, and the universe is no longer well described by classical theory."

Sure enough, Han Shuo still challenged the classical theories of physics.At this time, David on the other side of the computer stood up from the chair in shock, and couldn't help saying: "It's too crazy!"

"Its too crazy" means "too crazy". The reason why David said such a sentence was because he thought Han Shuo's words and deeds were too crazy from the bottom of his heart.Han Shuo just said that "classical theory can no longer describe the universe well", it is simply saying that I think this classical theory in physics cannot describe the universe well, so I want to question this theory, and I want to introduce my theory. own theory.That's why David said that Han Shuo was crazy.
