I Have a Little Black Hole
Chapter 1120 The technical strength behind the live signal
The other is the signal delay problem she mentioned. Many people may not understand how terrifying the Infinite Gravity Group can keep the live screen connection with the earth from so far away from Mars. Ordinary People don't care about that either.
But those who have a little scientific common sense and those experts who are watching the live broadcast are not greedy for such a technology, because it is very difficult for them to do this alone!
Mars is less than 55 million kilometers away from the earth when it is closest, and it is close to 400 million kilometers when it is the farthest. Even if it propagates communication signals at the speed of light of 300,000 kilometers per second, it will take a long time.
To say the last sentence on Mars, it takes 183.3 seconds for radio transmission to reach the earth, which means that people on Earth need more than three minutes to hear the words just said by people on Mars.
And if it is at the farthest distance, then the radio signal needs to travel 1333.3 seconds to arrive, which means that it takes 22.2 minutes to hear the words from the person on Mars, which is obviously very inconvenient.
This is still a single communication time, and the communication time between the two parties will be doubled, and because the distance is too far, it is easy to lose packets during the transmission of data packets. These problems restrict the communication between Earth and Mars important reason for speed.
Moreover, the transmission of such data packets is also difficult to achieve high-speed mutual transmission of a large amount of data. Every problem in this is not a simple problem to solve.
Although all countries are studying this problem and have proposed some solutions, the theory is a theory, and the distance from theory to reality has never been so simple, which is why the success rate of probes in various countries into Mars is not high. Important reason, because they have no way of near real-time remote control operations like they do in Earth orbit.
Why is the Infinite Gravity Group able to broadcast live events so far away? These experts can only analyze that they used more than a thousand relay satellites they have deployed in the solar system to achieve it, but even if they used a lot of There are relay satellites to achieve high-speed transmission of signals, and there should be some delays.
So why can it be seen from the pictures in the live broadcast room that the communication between the space station and the earth is almost real-time? You must know that they did the calculation by sending a message. From pressing the Enter button on the earth to seeing their speech on the live screen, the whole process only takes about 3 seconds, which is a bit incredible. .
However, Jiang Ziyu and the other astronauts obviously ignored this issue. It's enough to show you our live broadcast, but you still want to inquire about the company's core technology.
Of course, netizens are not happy to see these issues discussing boring technology.
So netizens with sharp eyes began to gossip, and one netizen asked curiously: I don't know if there is a problem with my eyes, why do I think Jiang Ziyu, you seem to have gained weight?
The figure is not very obvious, but the face seems to be a little rounder. Is it because the food on the space station is so good? I have been eating for more than 3 months, so I can't control my weight?
As soon as his question came out, he received a lot of likes and approvals, and many netizens who liked to do things responded in succession: I think so too! Solve!
Jiang Ziyu blushed instantly after seeing such a question and discussion, and she shouted angrily: What are you talking about! How can you tell that I'm fat? Where am I fat? It's not like a girl at all. Be polite or not!
Just look at my perfect body and you'll know you're thinking! Why is my face so rounded? It's called bloating, isn't it? It is the sequelae of being in a low-gravity environment for a long time!
Regarding her explanation, it is obvious that not everyone can be fooled by her, and some netizens said directly: Please, sister, we have watched your company's outer space live broadcast many times, okay?
Why haven't we found out that others have had the so-called sequelae of a low-gravity environment like yours? Is this only because of your special physique, sister?
Jiang Ziyu nodded again and again after seeing this statement: Yes, yes! It's like this, it doesn't mean that this situation won't happen to me if it doesn't happen to others!
I've never stopped exercising, otherwise we won't be able to keep working in the next Mars landing mission, and I haven't noticed any abnormality in my weight monitoring data, so don't think about it, I'm not fat at all!
Many people laughed at her quibble, and the netizen who asked this question before laughed and complained: Yes, yes! You are right, it may be that your fat has been transferred from other parts of your body to your face. On, I think this situation is worth looking into!
I strongly recommend that your company launch a research project on your situation. If you get results, remember to add my screen name to the paper. After all, I raised this question first, so I have a little credit!
Damn! Are you driving? Also, 'fat has been transferred from other parts of the body to the face', I just want to know where you can tell it's transferred from? Someone laughed and complained.
Yeah, please explain, the old driver will take us to learn!
Children under the age of 18 can get off the bus, it's time for adults to learn!
A group of old dirty turtles, but as a woman, I also want to know the answer to this question, but the focus of my attention is whether the fat on the face can be transferred to two parts of the body, or whether it can be put on the body. Fat from other places is also transferred to these two specific parts!
Therefore, I also support the Infinite Gravity Group to carry out research in this area. This is a research project of Gong Zaiqiu. Jiang Ziyu, you are our hope! A female netizen also commented with a smile.
Seeing her reply, everyone would laugh heartily. For a while, the whole Internet was full of joy. Sand sculpture netizens obviously never lost their enthusiasm for discussing this issue.
Jiang Ziyu is so angry at this group of people, what do you say, a beautiful astronaut like me is going to study this for you? But the live broadcast is like this. Who made her the image ambassador of Infinite Gravity Group? The existence of such a high popularity will of course cause netizens to pay high attention to her.
