"Dai... Senqiu?"
This is another term that Lianfeng has never heard of.
"Is it bigger than a star?"
Lianfeng continued to ask.
She had never heard of such a thing, so she naturally couldn't figure out how big Zhang Heng's so-called big thing was.
"At least bigger than an ordinary star, but according to my opinion, bigger is better, and it is best to reach the level of the largest celestial body in the known universe..."
Zhang Heng replied.
The currently largest known star is 3,200 times the sun, which means he wants to build a Dyson sphere as large as 3,200 suns combined.
As for whether it would be possible to build it, he didn't know, so he could only build it first and see.
The Dyson sphere is originally a giant artificial spherical structure conceived, mainly to surround the sun so that most of the sun's radiation energy is intercepted.
In this way, all the energy of the sun can be collected and utilized to a great extent, instead of being wasted like most of the solar energy radiation in normal times.
In fact, he has never seen what a Dyson ball looks like.
In the past, no one in the Trisolaran universe dared to use stars to make such a big splash.
"3200 times the size of the sun?"
Lianfeng took a breath, obviously frightened by Zhang Heng's bold idea!
Moreover, Zhang Heng also wanted to leave this project to her...
It's only the size of a sun. If she were really allowed to build it, 50,000 years would probably not be enough.
What's more, it's still 3,200 times the sun?
This is simply impossible!
What exactly is the concept of a sun?
Kesha, the strongest person in the known universe, can be knocked offline by a star...
If you want to play 3200 stars, you might not be able to play with Kesa, right?
How virtuous and capable are you?
Lianfeng felt at this moment that Zhang Heng thought highly of her too much!
"Isn't your real purpose to use this spherical structure to collect solar energy?"
After Lianfeng was shocked, he seemed to realize that Zhang Heng's true thoughts were probably far more than just collecting energy.
When Zhang Heng introduced the originally envisioned Dyson sphere, he said that this kind of thing was used to collect solar energy.
However, if it is only used to collect energy, then it only needs to wrap the sun. Why build it so big?
The distance between stars is often several light years or more.
Even if a structure could be built that could wrap around 3,200 stars, it would only be able to wrap around one, right?
"Yes, stellar energy is of little use to me now. The Dyson sphere is indeed used for another purpose..."
Zhang Heng nodded and then explained to Lianfeng.
What he said was correct. If he wanted to use stellar energy, he wouldn't have to go to such trouble.
Just like before, directly cut off the space where the star is located, and then use the whole one.
Regarding the role of the Dyson sphere, he actually wanted to use it to change the cosmic background radiation.
In other words, on the basis of the cosmic background radiation, some more radiation is added.
Cosmic background radiation is electromagnetic radiation generated from the Big Bang. If there is no interference from external forces, this radiation can be observed by any civilization anywhere in the universe.
Once in the Trisolaran universe, after the Trisolarans sent sophons to the earth, they had the sophons change and affect the cosmic background radiation around the earth.
This move frightened the Earth's turkey scientists at that time into a daze.
So, what does Zhang Heng want to do now? He wants to use such a large Dyson sphere and add some radiation to the cosmic background radiation. What exactly does he want to do?
Could it be that he also wanted to become a farmer once and scare other low-civilized turkey scientists?
of course not.
His real intention is to add some radiation waves containing information to the cosmic background radiation to convey a message to all civilizations;
The universe is not a dark forest. There is an earth in the universe where all civilizations can communicate harmoniously and make progress together.
This place is the location of the radiation information source, which is also the location of the Dyson sphere.
So what's the benefit to him?
Of course there are benefits, and there are many more.
Since he planned to obtain scientific and technological inspiration by observing these civilizations, instead of observing them one by one, he might as well have them come to his door for his own observation.
Near the Dyson Sphere, Zhang Heng also has a plan to build a civilized trading ground.
The civilizations that come to the trading field can realize what they need by exchanging technology.
In this way, these civilizations who come to the trading field can be promoted more quickly and achieve a certain degree of progress.
After all, different ways of thinking create different technologies.
Being able to communicate with different civilizations and even switch to different civilizations' technologies is definitely better than working behind closed doors.
As these civilizations progressed, Zhang Heng would naturally be able to obtain more technological inspiration.
However, these will not be implemented until many thousands of years later, when the enlightened seed civilizations have grown up and the Dyson Sphere will be built.
By then, the universe will twinkle for all civilizations, and all civilizations will be able to observe this message from the cosmic background radiation.
Of course, just one Dyson sphere is certainly not enough to cover the entire known universe.
Even though this Dyson sphere is 3,200 times larger than an ordinary star, its radiation power is 3,200 times greater than that of an ordinary star.
Therefore, a galaxy like the Milky Way, which is hundreds of thousands of light years old, must have more than countless stars.
Even if possible, Zhang Heng would like to build one within a thousand light years.
This is done not only for the sake of the radiation speed of the Dyson sphere, but also for the sake of civilizations that want to follow the radiation source of the Dyson sphere.
In the future, those seed civilizations that have been enlightened and grown will only be able to fly into space when they have the ability to observe radiation waves.
Moreover, even if they enter a space-level civilization, their sailing speed will not exceed the speed of light.
In a range of a thousand light years, even if they observe radiation information, it will still take thousands, tens of thousands, or even longer to get to the vicinity of the Dyson sphere.
However, Zhang Heng will no longer reduce the density of the Dyson sphere.
If a civilization does not have the courage to spend thousands or tens of thousands of years pursuing progress, then Zhang Heng will not expect this civilization to bring him any surprises, whether you love it or not.
However, although Zhang Heng's ideas are grand, they are only preliminary ideas.
If you want to truly implement it, you must start by building a Dyson sphere.
"We still need to build one within a thousand light-years distance..."
After listening to Zhang Heng introduce his idea again, Lianfeng felt numb again!
