Jiang Cheng's voice sounded in the live broadcast room.
In our current observable universe, the space is 95.4 billion light years, and the number of galaxies has reached 103.4 billion. Almost every galaxy is as big as the Milky Way."
" According to Fermi's speculation and calculation, the number of stars in these galaxies is conservatively estimated to be 165.2 billion to close to 1 trillion. We'll take the minimum value and take 165.2 billion."
"Take the sun as an example. It is impossible for all 100 billion stars to be suitable for human habitation, so we use the elimination method.”
" If the star's mass is too large, its lifespan will be too short. If the mass is too small, the light emitted will be weak, unstable, and unable to produce life. Fermi estimates that about 5% to 30% of the stars in the universe meet the standard of the sun. Then we will also take the minimum value, 5%"
" Planets generally revolve around stars. The screening criteria for planets are that they are too close to the sun and too hot to produce life, and too far away from the sun and too cold to produce life. Fermi has made precise calculations. This is a 6% probability. Let's take the lower limit, 6%.”
" How many planets in the universe are like Earth that can give birth to life and are suitable for life? But we all know that the conditions for life are too harsh, with a suitable atmosphere and sufficient water, so the probability is only about one in ten thousand.”
" What I said above is the data we need to calculate how many alien civilizations may exist in the universe. In the end, we only need to substitute these data into the algorithm I obtained from solving the NP-complete problem. The final result is 10 to the power of 14 and 57. However, I used the minimum value of the data to calculate.”
After saying this, Jiang Cheng smiled.""I've finished answering. I wonder if Little Sister is satisfied?”
Bullet comments:
"F * ck, over a hundred trillion alien civilizations.”
"This is too f * cking terrifying. A universe is too magical.”
"Or is it because our human civilization is still too underdeveloped? There will definitely be other civilizations.”
"The universe is so big. There are many things that we have never explored before. It's too unbelievable.”
"I've really learned something. It turns out that our Earth is really a frog at the bottom of a well in the universe.”
"In ancient times, alien civilizations must have been here. Otherwise, how could they have created those amazing ruins?”
"I told you that the ancient people's wisdom was not lower than ours.”
...................................
"Miss, are you still there?"
In the live broadcast room, after Jiang Cheng finished speaking, he did not hear the other party's reply. Jiang Cheng asked in puzzlement.
"Yes, thank you very much for your answer. Also, can I ask you about the only algorithm for the NPC problem?”
"I'm sorry, I don't have much time right now. You can watch the recording of my first live broadcast. It should be helpful to you.”Jiang Cheng laughed.
"Thank you, then. I'll get off first."
Jiang City didn't agree, and the other party didn't force it. After greeting him, he went offline.
Bullet comments:
"Ghostly, the streamer is a straight man of steel.”
"Why do I hear disappointment in Little Missy's tone?”
"I feel like Little Sister has suffered a blow.”
"What do you want, little sister? What's the use of that thing? I only love science."
"To be able to talk to a god like the streamer, it seems that the other party is not simple.”
....................................
At the same time.
At a single apartment in B City.
It was a doll with a hot figure and a cold temperament. It was venting its anger on the bed with a delicate beauty.
"Damn it, damn it. I, Li Yu, have never been so embarrassed in front of a man since I was born.”
The one who was throwing a tantrum was Li Yu, the granddaughter of the deputy director of the Institute of Mathematics at the Chinese Academy of Sciences. She entered the Chinese University of Science and Technology at the age of 15 and went to MIT after graduation. Now that she had obtained her PhD, she returned to China to develop her career.
It could be said that Li Yu was the youngest female doctor in the country with a PhD from MIT. She was in her twenties, had a hot body, and was beautiful. She was definitely a goddess-level top student.
The limelight in Jiang City these two days had aroused Li Yu's interest.
Later, after watching the live broadcast of Jiang City on the Internet, Li Yu became even more interested in Jiang City.
Therefore, when Jiang City used the bullet screen lottery system to randomly draw the lucky audience, she wrote a Mini programs to make herself the first to be selected by the lottery system.
He had originally planned to personally test the bottom of Jiang City, but he did not expect to be defeated so thoroughly in front of Jiang City.
"Jiang City, I must kill your spirit.”Unwilling to admit defeat, Li Yu secretly swore.
Li Yu revealed a mysterious smile when he recalled the live broadcast in Jiang City and how he said that he was now a member of the Chinese Academy of Sciences.
Then, he made a call.
Li Hongyan, who was watching the live broadcast, realized that his granddaughter had called him and quickly picked up the phone.
"Yu 'er, why are you calling grandpa now?”Li Hongyan said dotingly.
"Grandpa, I've decided. I want to enter the Chinese Academy of Sciences.”Li Yu said.
"Really? Have you really thought it through?" Li Hongyan said excitedly.
Li Yu was fully qualified to enter the Chinese Academy of Sciences. Li Hongyan had always wanted his granddaughter to come in and contribute to the country's scientific research, but Li Yu had never agreed.
"I've thought about it. I'll report in the next few days.”Li Yu said.
"Alright, I'm going back soon. I'll make arrangements for you.”Li Hongyan said happily.
The call ended.
"Master, Li Yu is coming to the Chinese Academy of Sciences?”After hearing this news, Song Shi felt a chill down his spine.
"Yes."
"Once she comes, we'll be despised by her again.”Song Shi looked sad.
"Look at your useless appearance. This girl is most likely here for Jiang City. It won't be your turn this time.”Li Hongyan said proudly.
"That's true. It's much more comfortable now." Song Shi seemed to have thought of something and instantly smiled as brightly as a chrysanthemum.
