Brilliant images surrounded Xiao Li, his left and right hands were raised in a loop, the image of the sun was played with by him, and the people below did not speak. Pen % fun % Pavilion www.biquge.info

Their mouths were wide open, and their eyes reflected the image of the sun.

That's exactly what happened!

That's the purpose of building the Dyson Sphere!

They couldn't imagine that Xiao Li's words were too impactful.

They need time to digest.

Xiao ...... Academician....... A college student in a blue plaid shirt opened his mouth, his mind still hadn't recovered from the impact just now, and his voice stuttered a little, "Dyson ball...... How is it...... Establish? ”

The more he spoke, the smoother he became, and his arms waved, "According to Anders? Sandberg calculates that if a Dyson sphere were built enough to wrap around the sun, the area of this Dyson sphere would reach a terrifying 2.72 x 10 17 square kilometers, which is 600 million times the surface area of the earth. ”

"How should we build such a huge sphere?"

In front of the Dyson Sphere, the Eight Wonders of Shenma, the Pyramid of Shenma, and the Great Wall of Shenma are not worth mentioning. The Great Wall is long, can it grow as long as a Dyson ball?

No, not one, in the face of a Dyson sphere that is larger than the earth, how to build it is the biggest problem.

"This classmate." Xiao Li looked at his immature face and said with a smile: "You may not have noticed what I said earlier, I used 'one or more' to describe the Dyson ball. ”

"Actually, in the original idea of the Dyson sphere, it wasn't the solid sphere you imagined...... Dyson's original assumption was to assume that there were enough solar collectors around the star to absorb light energy, and he never said that the Dyson sphere must be a continuous shell-like object, so Anders? Mr. Sandberg's calculations were wrong. ”

The student's face was flushed, he had made such an obvious mistake, but he thought about it and was a little unwilling, so he continued to ask, "But even so, the construction of the Dyson sphere is beyond human expectations, it will be the largest project of all mankind, so large that it is beyond the limits of human ability." ”

"You're wrong again." Xiao Li replied lightly, "Newton University physicist Stuart? Armstrong once designed a solution for the creation of the Dyson sphere, and I thought it was perfect, so I used it directly...... If Stuart? Armstrong wants royalties, and I'll give them with both hands. ”

Xiao left the joke, then restrained his smile, "In Stuart? In Armstrong's plan, he divided the construction of the Dyson sphere into five steps. ”

"The first is to get energy, which is to build a small part of the Dyson sphere on the earth, and then collect the energy so that it can be used to support the rest of the work."

"Second, mining on Mercury, which has very rich resources on it, of course, just one Mercury is not enough, according to Stuart? Mr. Armstrong calculated that the construction of the Dyson sphere would require the removal of Mercury and Venus, as well as the asteroids that surround them, in order to build the Dyson sphere. ”

Why Mercury? Because Mercury has all the raw materials needed to build a Dyson Sphere, through it, the Dyson Sphere will not be worried about running out of materials at all.

"Thirdly, put the material into orbit ......."

"Fourth, make solar collectors ......."

"Fifth, the Dyson sphere was built successfully!"

Xiao Li's Stuart? Armstrong's plan was spoken, but he didn't copy it, "In Stuart? Mr. Armstrong's plan would take hundreds of years to build a successful Dyson sphere, but I think it would only take a few decades. ”

"It's simple, Stuart? When Mr. Armstrong proposed this idea, we had not yet popularized robots, and the aerospace capability was far from being as strong as it is now, and his idea was based on automation, in his idea, first build a part, and then put the part that was built in front of it into operation to provide energy for subsequent construction. ”

"But now it's different, robots are widely available, and we don't need to go to Mercury Mining to transport the ore back at all, just build a Dyson ball directly on Mercury."

"So here's my plan."

"First and second and Stuart? There is no difference between Mr. Armstrong's proposal, but third and fourth, I think it should be changed to build a Dyson sphere on Mercury and carry it directly to the vicinity of the sun's orbit. ”

"That's my plan, I estimate it will be built in 30 years."

"Thirty years?" The student asked, "Isn't thirty years too long?" In thirty years, I'm afraid that alien civilizations have already discovered us. ”

"No, it won't." Xiao Li smiled faintly, "This classmate, your understanding of the universe may still be stuck in some science fiction novels. ”

"In the novel, the universe is so small that a spaceship can fly through the universe, but the truth is that the universe is so big that it takes 13 billion years for a light-speed spaceship to fly from one end of the universe to the other."

"Thirty years may be a long time for us, but it is very short for civilization."

"Short-lived enough for the sun to transmit our information only into space."

"You don't think that there is a powerful civilization within thirty light years of us, do you?"

The universe is so vast, a civilization like the lizard civilization separated by 4.2 light years is definitely rare, otherwise, the earth would not have existed until now, and even the lizard civilization has discovered the earth civilization that is close at hand, and the civilization that destroys the lizard star cannot be unaware of the earth civilization.

So he was sure that there was absolutely no powerful civilization near the planet.

"But the message keeps coming." The student asked, "Sooner or later, this information will be transmitted to the detectors of other civilizations, and at that time, won't we still be hit by the Dark Forest?" Rather than that, why build a Dyson sphere? What's the point? Is it just to comfort our own human psyche? ”

"That's why you need to disguise." Xiao Li explained, "In my imagination, the false information released by photon sequencing will perfectly cover the information of the earth civilization, whether it is disguised as the earth civilization being wiped out or the earth civilization has shifted its position, it will erase the influence of the information transmitted before. ”

"Of course, we will calculate what the disguise will look like through the computer, and in terms of probability, the computer will calculate much more accurately than us."
